GENERAL SAFETY RULES

WARNING!

Read all instructions

Failure to follow all instructions listed below may result in

electric shock, ﬁ re and/or serious injury.

The term “power tool” in all of the warnings listed below

refers to your mains operated (corded) power tool or battery

operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

1) Work area

a) Keep work area clean and well lit.

Cluttered and dark areas invite accidents.

b) Do not operate power tools in explosive

atmospheres, such as in the presence of

ﬂ ammable liquids, gases or dust.

Power tools create sparks which may ignite the dust

of fumes.

c) Keep children and bystanders away while

operating a power tool.

Distractions can cause you to lose control.

2)

Electrical safety

a) Power tool plugs must match the outlet.

Never modify the plug in any way.

Do not use any adapter plugs with earthed

(grounded) power tools.

Unmodiﬁ ed plugs and matching outlets will reduce

risk of electric shock.

b) Avoid body contact with earthed or grounded

surfaces such as pipes, radiators, ranges and

refrigerators.

There is an increased risk of electric shock if your

body is earthed or grounded.

c) Do not expose power

tools to rain or wet

conditions.

Water entering a power tool will increase the risk of

electric shock.

d) Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool.

Keep cord away from heat, oil, sharp edges or

moving parts.

Damaged or entangled cords increase the risk of

electric shock.

e) When operating a power tool outdoors, use an

extension cord suitable for outdoor

use.

Use of a cord suitable for outdoor use reduces the

risk of electric shock.

3) Personal safety

a) Stay alert, watch what you are doing and use

common sense when operating a power tool.

Do not use a power tool while you are tired

or under the inﬂ uence of drugs, alcohol or

medication.

A moment of inattention while operating power tools

may result in serious personal injury.

b) Use safety equipment. Always wear eye

protection.

Safety equipment such as dust mask, non-skid

safety shoes, hard hat, or hearing protection used for

appropriate conditions will reduce personal injuries.

c) Avoid accidental starting. Ensure the switch is in

the oﬀ position before plugging in.

Carrying power tools with your ﬁ nger on the switch or

plugging in power tools that have the switch on invites

accidents.

d) Remove any adjusting key or wrench before

turning the power tool on.

A wrench or a key left attached to a rotating part of the

power tool may result in personal injury.

e) Do not overreach. Keep proper footing and

balance at all times.

This enables better control of the power tool in

unexpected situations.

f) Dress properly. Do not wear loose

clothing or

jewellery. Keep your hair, clothing and gloves

away from moving parts.

Loose clothes, jewellery or long hair can be caught in

moving parts.

g) If devices are provided for the connection of

dust extraction and collection facilities, ensure

these are connected and properly used.

Use of these devices can reduce dust related

hazards.

4) Power tool use and care

a) Do not force the power tool. Use the correct

power tool for your application.

The correct power tool will do the job better and safer

at the rate for which it was designed.

b) Do not use the power tool if the switch does not

turn it on and oﬀ .

Any power tool that cannot be controlled with the

switch is dangerous and must be repaired.

c) Disconnect the plug from the power source

before making any adjustments, changing

accessories, or storing power tools.

Such preventive safety measures reduce the risk of

starting the power tool accidentally.

d) Store idle power tools out of

the reach of children

and do not allow persons unfamiliar with the

power tool or these instructions to operate the

power tool.

Power tools are dangerous in the hands of untrained

users.

e) Maintain power tools. Check for misalignment or

binding of moving parts, breakage of parts and

any other condition that may aﬀ ect the power

tools’ operation.

If

damaged, have the power tool repaired before

use.

Many accidents are caused by poorly maintained

power tools.

f) Keep cutting tools sharp and clean.

Properly maintained cutting tools with sharp cutting

edges are less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits

etc., in accordance with these instructions and

in the manner intended for the particular type

of power tool, taking into account the working

conditions and

the work to be performed.

Use of the power tool for operations diﬀ erent from

intended could result in a hazardous situation.

5) Battery tool use and care

a) Ensure the switch is in the oﬀ position before

inserting battery pack.

Inserting the battery pack into power tools that have

the switch on invites accidents.

b) Recharge only with the charger speciﬁ ed by the

manufacturer.

A charger that is suitable for one type of battery pack

may create a risk of ﬁ re when used with another

battery pack.

c) Use power tools only with speciﬁ cally designated

battery packs.

Use of any other battery packs may create a risk of

injury and ﬁ re.

English

7

d) When battery pack is not in use, keep it away

from other metal objects like paper clips, coins,

keys, nails, screws, or other small metal objects

that can make a connection from one terminal to

another.

Shorting the battery terminals together may cause

burns or a ﬁ re.

e) Under abusive conditions, liquid may be ejected

from the battery; avoid

contact. If contact

accidentally occurs, ﬂ ush with water. If liquid

contacts eyes, additionally seek medical help.

Liquid ejected from the battery may cause irritation or

burns.

6) Service

a) Have your power tool serviced by a qualiﬁ ed

repair person using only identical replacement

parts.

This will ensure that the safety of the power tool is

maintained.

PRECAUTION

Keep children and inﬁ rm persons away.

When not in use, tools should be

stored out of reach of

children and inﬁ rm persons.

PRECAUTIONS FOR CORDLESS STUD CUTTER

1. Never bring the cutter near your ﬁ ngers when operating

the switch.

2. Do not use for cutting screws other than soft steel studs.

This tool is designed especially for cutting of soft steel

studs. Using this tool for brass or stainless steel screws

could cause distortions in the screw threads,

thereby

preventing insertion of nuts.

Never use to cut tempered bolts, screws of diﬀ ering

sizes, reinforcing rods, etc.

3. Use by changing the special cutters according to the size

of the studs. Cutting with cutters of the wrong size could

damage to the continuous thread studs or the cutter

edges.

4. Make sure that the threads on the studs and those on the

cutter are correctly meshed before starting to cut. Cutting

when the threads are not meshed could cause damage

to the studs and the cutter.

5. If the cutter has been attached in the wrong direction or

the bolt

for cutter attachment is loose, this could cause

damage to the cutter edge and could lead to premature

damage to the main unit.

Be very careful to attach the cutter correctly.

6. Cutting studs at short lengths of 10 millimeters or less will

create an insuﬃ cient meshing length between the

cutter

and studs, thus causing damage to the cutter. Always cut

at lengths of more than 10 millimeters.

7. When cutting studs secured to narrow locations, be sure

that there is at least 8 millimeters between the stud and

the surrounding materials.

If the distance is less than 8 millimeters the

cutter could

contact the surrounding materials, thereby causing

damage to the cutter and the main unit.

8. When inspecting, cleaning or replacing the cutter, be

sure to remove the battery from the main unit. The

switch could be turned on accidentally, thereby causing

accidents.

9. When using this equipment at heights,

make doubly

sure prior to use that there is no one standing in the

area immediately below you. Place the tool in a safe and

stable place when not using at the moment.

10. Always charge the battery at a temperature of 0 – 40°C.

A temperature of less than 0°C will result in over charging

which is dangerous. The battery cannot be charged at

a temperature greater than 40°C. The most suitable

temperature for charging is that of 20 – 25°C.

11. Do

not use the charger continuously.

When one charging is completed, leave the charger for

about 15 minutes before the next charging of battery.

12. Do not allow foreign matter to enter the hole for

connecting the rechargeable battery.

13. Never disassemble the rechargeable battery and

charger.

14. Never short-circuit the rechargeable battery.

Short-

circuiting the battery will cause a great electric current

and overheat. It results in burn or damage to the battery.

15. Do not dispose of the battery in ﬁ re.

If the battery is burnt, it may explode.

16. Do not insert object into the air ventilation slots of the

charger.

Inserting

metal objects or inﬂ ammables into the charger

air ventilation slots will result in electrical shock hazard or

damaged charger.

17. Bring the battery to the shop from which it was purchased

as soon as the post-charging battery life becomes too

short for practical use. Do not dispose of the exhausted

battery.

18. Using an exhausted battery will damage the charger.

1 When using the M10, M8 or M6 cutter

Check and conﬁ rm that the accessory M6, M8 or M10

spacers are correctly inserted respectively between

bracket (A) and the cutter and bracket (B) and the cutter

(Fig. 6).

CAUTION

If the spacers are not attached or if spacers of

the wrong

size are used, the threads of the cutter and the studs will

not properly mesh, thereby causing damage to the studs

and the cutter edge. Be sure to attach spacers correctly.

2 When using the W3/8" cutter

No spacers are required. Check and conﬁ rm that only the

cutter

is attached.

For details, refer to the section on “Cutter life and

replacement”.

5. Correctly insert the stud guide

The stud guide is used to prevent tilting during cutting of

studs. Correctly adjust the dial calibration to the mark (

△)

depending on the size of the stud to be cut (Fig. 7).

CAUTION

If the size of the stud and the dial position to do not agree,

the cut section may be subjected to burrs or its shape

may be distorted, which may result in damage to the main

unit.

HOW TO USE

CAUTION

○ Never bring the cutter near your ﬁ ngers when operating

the trigger switch.

○ When cutting short studs, take caution as to not place

your ﬁ ngers in the space between the short stud and

main unit, such as the guard section (see Fig. 8), battery,

etc.

○ After cutting, the cut

section of the stud is very sharp and

therefore dangerous. Be very careful when handling the

stud.

1. Normal Cutting Method

(1) Pull the trigger switch and move bracket (A), stopping

with the cutter in the open position shown in Fig. 8.

(2) As shown in Fig. 9, set the stud

to be cut in the cutter

on the bracket (B) side, making sure that the threads

correctly mesh with each other.

(3) While maintaining the stud in a horizontal position, pull

the trigger switch all the way to cut the stud (Fig. 8).

(4) After cutting turn oﬀ the switch

with bracket (A) facing

directly upward. The unit stops with the cutter in the open

position, thus making it easier to proceed to the next

operation.

2. Number of cuttings (per battery charging)

Refer to the chart below for the number of cuttings per

battery charging.

Table 4

Battery M10 M8 M6 W3/8"

BSL1430 660 1020 1520 740

The number of cuttings can also vary somewhat

according to the ambient temperature, characteristics of

the battery and the condition of the cutter.

3. Cutting ﬁ xed lengths (Fig. 10)

When cutting several studs to the same length, using

the equipment in the following way will making cutting

operations more

eﬃ cient.

(1) First cut one stud to the required length, and then use it

as a ﬁ xed length guide.

CAUTION

○ When the battery charger has been continuously used,

the battery charger will be heated, thus constituting

the cause of the failures. Once the charging has been

completed, give 15 minutes rest until the next charging.

○ If the battery is recharged when it is warm due to battery

use or

exposure to sunlight, the pilot lamp may light in

green.

The battery will not be recharged. In such a case, let the

battery cool before charging.

○ When the pilot lamp ﬂ ickers in red (at 0.2-second

intervals), check for and take out any foreign objects

in the charger’s battery installation hole.

If there are no

foreign objects, it is probable that the battery or charger

is malfunctioning. Take it to your authorized Service

Center.

PRIOR TO OPERATION

1. Preparing and checking the work environment

Make sure that the work site meets all the conditions laid

forth in the precautions.

2. Checking the battery

Make sure that the battery is installed ﬁ rmly. If it is at all

loose it could come oﬀ and cause an accident.

3. Setting the

forward/reverse switching button

(1) Push the forward/reverse switching button from the right

as shown in Fig. 5 (a). Cutting is possible.

(2) By setting the forward/reverse switching button in the

lock position as shown in Fig. 5 (b), the motor will not

operate even if the trigger switch is pulled. When

carrying

or storing the main unit or when stopping operations, set

the forward/reverse switching button to the lock position

(Fig. 5 (b)).

(3) Push the forward/reverse switching button from the left

as shown in Fig. 5 (c). With the button held down, pull

the trigger switch so that the

cutter can be removed from

the stud. Only set to this position if the rechargeable

battery is worn out and the unit stops operating during

cutting. Immediately turn oﬀ the switch after the cutter

has been removed from the stud.

If you remove your ﬁ nger, the forward/reverse switching

button automatically

returns to the lock position (Fig. 5

(b)).

CAUTION

Do not attempt to cut in the reverse position (Fig. 5 (c)).

If you attempt to cut in this position, there will be an

overload on the motor and cutting will not be possible.

Never apply excessive force to the

main unit as this can

cause damage to the unit.

4. Check the cutter size, attachment direction,

attachment bolt and spacer

(1) The cutter size diﬀ ers according to the size of the studs to

be cut. Make sure that a cutter is attached that conforms

to the size of the

studs to be cut.

(2) Cutter attachment includes directionality. Make sure that

the cutter has been attached so that the side without the

notch on the cutter can be seen on bracket (A) (movable

side) when the main unit is viewed from the front or that

the notch on the cutter

surface can be seen on bracket

(B) (ﬁ xed side).

(3) Use the accessory hexagonal wrench to insure that the

hex. socket hd. bolt for attaching the cutter is securely

tightened (Fig. 6). Using the equipment while the bolt is

loose could cause damage to the main unit and cutter.

(4)

Depending on the size of the studs it may be necessary

to attach special spacers to the cutter.

English

11

(2) Insert the stud used as a ﬁ xed length guide in the stud

attachment hole found on the main unit stud guide and

use the hexagonal bar wrench to tighten and secure

the hex. socket hd. bolt. Adjust at this time so that the

distance between the end of the stud

used as a ﬁ xed

length and the cutter is the necessary length.

(3) Insert the stud for cutting in the cutter, aligning the end

with that of the stud used as a cutting guide, and then cut

the stud.

4. Cutting studs that are already secured (Fig. 11)

When cutting studs

that are suspended from the ceiling

or secured to walls or ﬂ oors.

When inserting the stud in the cutter, the meshing of

the stud thread and cutter thread is unstable. In such

a case, after inserting the stud in the cutter, lightly pull

the trigger switch to close the cutter at

low speed and

then completely mesh the stud and the upper and lower

cutters. Next, pull the trigger switch all the way to cut the

stud.

CAUTION

Use your one hand to hold the stud on the side released

by cutting to insure that it does not fall unexpectedly.

5. Removing the

screw from the unit during cutting

operations

If the battery wears out during cutting operations so that

the motor stops rotating, pull the trigger switch while

pushing the forward/reverse switching button to the

reverse side (Fig. 5 (c)). The motor will rotate in the

opposite direction and it will

be possible to remove the

stud from the cutter(Fig. 12).

CAUTION

○ When removing a stud that is suspended from the

ceiling, hold the main unit with both hands to prevent

any possibility of the stud falling.

○ Immediately turn oﬀ the switch once the cutter is free

from the stud.

If you attempt to do this with the switch

turned on, the cutter might cut into the stud again.

6. Using the hook

The hook can be used to hang up the unit temporarily

during operations (Fig. 13).

CAUTION

The hook should never be used to hang the unit on your

person.

When using the hook, check to make sure that the main

unit will not slip and fall, or become unstable by the wind,

etc.

Never hang the unit from your belt or trousers as this

could cause accidents.

NOTE:

During normal use or during storage, store the hook in the

latch found on the bottom of the main unit.

7. Using the trimmer

NOTE: Use a special trimmer that is suitable for the size

of the stud.

If it is diﬃ cult for the nut to enter the cutting position,

either use a wrench to ﬁ rmly tighten the nut or

use the

accessory trimmer to remove the ﬂ ange on the screw

thread.

Insert the stud in the hole on the grip. Use a pliers to

retain the stud and rotate the trimmer 5 or 6 times to the

right to remove the ﬂ ange and then rotate in the opposite

direction to

remove the trimmer (Fig. 14).

CAUTION

This trimmer is specially designed for Studs Cutter. The

ﬂ ange on studs cut with a hacksaw or disc grinder is too

large for this trimmer so that the trimmer does not rotate

and it is not possible to remove ﬂ ange.

8. About Remaining Battery Indicator

When pressing the remaining battery indicator switch,

the remaining battery indicator lamp lights and the

battery remaining power can be checked. (Fig. 15) When

releasing your ﬁ nger from the remaining battery indicator

switch, the remaining battery indicator lamp goes oﬀ . The

Table 5

shows the state of remaining battery indicator

lamp and the battery remaining power.

Table 5

State of lamp Battery Remaining Power

The battery remaining power is

enough.

The battery remaining power is a half.

The battery remaining power is nearly

empty.

Re-charge the battery soonest

possible.

As the remaining battery indicator shows somewhat

diﬀ erently depending on ambient temperature and

battery characteristics, read it as a reference.

NOTE:

○ Do not give a strong shock to the switch panel or break

it.It may lead to a trouble.

○ To save the battery power consumption, the remaining

battery indicator lamp lights while pressing the remaining

battery indicator switch.

CUTTER LIFE AND REPLACEMENT

1. Cutter life

As is shown in Fig. 17, repeated cutting can cause

breaking and warping of the cutter edge. Using the

cutter in this condition can produce ﬂ ange on the cutting

location of the studs so that the threads are distorted.

This will prevent clean cuts and make it

impossible to

insert the nut.

Breaking Warping

Fig. 17

As is shown in Fig. 18, the edge is found on four locations

on the cutter. Use the method described below to change

the attachment direction of the cutter to allow a total of

four usages.

If the nut does not ﬁ t on the screw due to breaking

and

warping of the edge, change the cutter attachment

direction to use the edge without breaking and warping

or replace with a new cutter.

2. Changing the cutter attachment direction or

replacing the cutter

(1) Before removing:

1 Pull the trigger switch and move bracket (A), stopping

with the cutter in the open position.

2 Set the forward/reverse switching button to the lock

position (Fig. 5 (b)).

3 Remove the rechargeable battery from the main unit.

(2) Removal

Use the accessory hexagonal bar wrench to remove the

hex. socket hd. bolt. It is now possible to remove the

cutter and spacer.

(3) Before attaching

1 There are four edges on the cutter. As shown in Fig. 19,

by changing the position of the edge it is possible

to use

the blade four times.

3 If there is breakage or warping on the cutter edge or if

there are bulges on the cutter attachment surface, use a

ﬁ le to the areas ﬂ at.

4 Use brush to remove the ﬁ lings attached to the cutter

attachment groove on the bracket.

CAUTION

As shown in Fig.

21, if the cutters are combined in such

a way that both side without the notch on the cutter or

both notch sides are facing out, the pitch of the threads

on the studs and the threads on the cutter will not be in

agreement. This can cause damage to

the cutter edge or

cause wear to premature damage to the main unit.
