General Safety Summary
Observe these safety precautions when using the K420 Bench Cart.
Keep the K420 Level
Keep the K420 level at all times, especially when it is loaded with instruments.
The cart is designed to be very stable, but it can fall over if tilted to extremes.
Observe this precaution especially in these cases:
H When rolling the cart across uneven floors.
H When rolling the cart through doorways with uneven thresholds.
H When lifting the cart wheels over cables.
H When rolling the cart up or down ramps.
Do Not Overload Shelves
Do not put more weight on any cart shelf than is listed in the specifications.
Load the top of the cart evenly.
Observe Electrical Safety
All parts of the cart must be treated as electrical conductors, even if they appear
to be nonconducting. Do not rely on the casters to provide insulation between the
cart and the surface it stands on. Conversely, do not rely on the casters to provide
a conductive ground path for the cart.
Test the Stability of Custom Configurations
Changes in shelf location and loading can af fect the balance of the cart. If you
arrange the shelves differently from the configuration described in this manual,
test the cart carefully for stability before using it.

Introduction
The Tektronix K420 Bench Cart requires some assembly. This manual tells how
to assemble and use the cart.
You can assemble the K420 Bench Cart by yourself, but it is easier if you have
another person to help you.
You will need a large flat area to assemble the cart. The area should be level and
large enough to move the various parts into place. A carpeted floor space is ideal.
Tools
You will need a 3/4 inch (19 mm) open--end wrench, or an adjustable wrench that
can be adjusted to that size.
Other tools are included with the K420 Bench Cart. These include a 5/32 inch
Allen wrench, a 3/16 Allen wrench, a 1/8 inch Allen wrench, and a circular
bubble level.
Parts Identification
The large pieces of the K420 Bench Cart are packed separately in the shipping
carton. A bag of small parts is packed in a box with these instructions. The
included tools are also packed in this bag. Figure 1 on page 2 shows the small
parts you will be using.
Table 1 on page 3 lists all the parts needed to assemble the cart, including the
large pieces and assemblies. Take an inventory now to familiarize yourself with
the parts for the assembly process.
