MAINTENANCE
MAINTENANCE, REPLACEMENT OR REPAIR OF THE
EMISSION CONTROL DEVICES AND SYSTEMS MAY
BE PERFORMED BY ANY NON-ROAD ENGINE REPAIR
ESTABLISHMENT OR INDIVIDUAL.
Carburetor adjustment (Fig. 27)
WARNING
The cutting attachment may be spinning during
carburetor adjustments.
Never start the engine without the complete clutch
cover and tube assembled! Otherwise the clutch can
come loose and cause personal injuries.
In the carburetor, fuel is mixed with air. When the engine is
test run at the factory, the carburetor is basically adjusted.
A further adjustment may be required, according to
climate and altitude. The carburetor has one adjustment
possibility:
T = Idle speed adjustment screw.
Idle speed adjustment (T)
Check that the air fi lter is clean. When the idle speed is
correct, the cutting attachment will not rotate. If adjustment
is required, close (clockwise) the T-screw, with the engine
running, until the cutting attachment starts to rotate. Open
(counter-clockwise) the screw until the cutting attachment
stops. You have reached the correct idle speed when the
engine runs smoothly in all positions well below the rpm
when the cutting attachment starts to rotate.
If the cutting attachment still rotates after idle speed
adjustment, contact a HITACHI dealer.
NOTE
Standard Idle rpm is 2500 – 3000 rpm.
WARNING
When the engine is idling the cutting attachment must
under no circumstances rotate.
Air fi lter (Fig. 28)
The air fi lter must be cleaned from dust and dirt in order
to avoid:
○ Carburetor malfunctions.
○ Starting problems.
○ Engine power reduction.
○ Unnecessary wear on the engine parts.
○ Abnormal fuel consumption.
Clean the air fi lter daily or more often if working in
exceptionally dusty areas.
Cleaning the air fi lter
Remove the air fi lter cover and the fi lter (24). Rinse it
in warm soap suds. Check that the fi lter is dry before
20
reassembly. An air fi lter that has been used for some time
cannot be cleaned completely. Therefore, it must regularly
be replaced with a new one. A damaged fi lter must always
be replaced.
Fuel fi lter (Fig. 29)
Drain all fuel from fuel tank and pull fuel fi lter line from tank.
Pull fi lter the element out of the holder assembly and rinse
the element in warm water with detergent.
Rinse thoroughly until all traces of detergent are
eliminated.
Squeeze, do not wring, away excess water and allow the
element to air dry.
NOTE
If element is hard due to excessive dirt buildup, replace
it.
Spark plug (Fig. 30)
The spark plug condition is infl uenced by:
○ An incorrect carburetor setting.
○ Wrong fuel mixture (too much oil in the gasoline).
○ A dirty air fi lter.
○ Hard running conditions (such as cold weather).
These factors cause deposits on the spark plug electrodes,
which may result in malfunction and starting diffi culties. If
the engine is low on power, diffi cult to start or runs poorly at
idling speed, always check the spark plug fi rst. If the spark
plug is dirty, clean it and check the electrode gap. Re-
adjust if necessary. The correct gap is 0.6 mm. The spark
plug should be replaced after about 100 operation hours or
earlier if the electrodes are badly eroded.
Muffl er (Fig. 31)
Remove the muffl er and clean out any excess carbon
from the exhaust port or muffl er inlet every 100 hours of
operation.
Cylinder (Engine cooling) (Fig. 32)
The engine is air cooled, and air must circulate freely
around the engine and over the cooling fi ns on the cylinder
head to prevent overheating.
Every 100 operating hours, or once a year (more often if
conditions require), clean fi ns and the external surfaces of
engine of dust, dirt and oil deposits which can contribute to
improper cooling.
NOTE
Do not operate the engine with the engine shroud or
muffl er guard removed as this will cause overheating
and engine damage.
Angle transmission (Fig. 33)
Check angle transmission or angle gear for grease level
about every 50 hours of operation by removing the grease
fi ller plug on the side of angle transmission.
If no grease can be seen on the
fl anks of the gears, fi ll
the transmission with quality lithium based, multipurpose
grease up to 3/4.
Do not completely fi ll the transmission.
Blade
WARNING
Wear protective gloves when handling or performing
maintenance on the blade. (Fig. 34)
○ Use a sharp blade. A dull blade is more likely to snag
and thrust. Replace the fastening nut if it is damaged
and hard to tighten.
○ When replacing the blade, purchase one recommended
by HITACHI, with a 25.4 mm fi tting hole.
○ When installing saw blade, always face the stamped
side up. 80-tooth blades can be used with either side
facing up.
○ Use the correct blade for the type of work.
○ When replacing blades, use appropriate tools.
○ When cutting edges become dull, re-sharpen or fi le
as shown in fi gure. Incorrect sharpening may cause
excessive vibration.
○ Discard blades that are bent, warped, cracked, broken
or damaged in any way.
NOTE
When sharpening blades it is important to maintain the
original shape of the radius at the base of the tooth to
avoid cracking.
Nylon head
Nylon line replacement
○ Remove the cutting body cap by pushing inward the
locking tabs on the side of the nylon head (Fig. 35).
Take out the spool (Fig. 36), hook the new nylon line
into the hole of the spool, then wind it around the spool
(Fig. 37).
When the nylon line has been wound around the spool,
temporarily fasten it in the opening of the spool at
about 10 cm from the end. (Fig. 38) Then thread the
nylon line through the hole on the side of the nylon
head and place the cutting body cap in reverse order
of the cap removal. Pull the right and left nylon lines
until they are secured about 15 - 16 cm from the end.
(Fig. 40)
NOTE
○ The nylon head is designed for nylon lines with an
outer diameter of 2.5 mm. Do not use nylon lines with a
diff erent outer diameter.
○ Make sure that the right and left nylon lines are of equal
length since vibrations will otherwise increase.
