General Safety Summary

Observe these safety precautions when using the K475 Workstation Tower.

Keep the K475 Level

Keep the K475 level at all times, especially when it is loaded with instruments.
The tower 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 tower across uneven floors.

H When rolling the tower through doorways with uneven thresholds.

H When lifting the tower wheels over cables.

H When rolling the tower up or down ramps.

Do Not Top-Load the K475

Do not load the top shelves of the K475 while leaving the bottom shelves empty.
That makes the tower top-heavy and easier to tip over. Load the top shelves only
if the bottom shelves are also loaded.

Do Not Overload Shelves

Do not put more weight on any tower shelf than is listed in the specifications.
Load the top of the tower evenly.

Observe Electrical Safety

All parts of the tower must be treated as electrical conductors, even if they
appear to be nonconducting. Do not rely on the casters to provide insulation
between the tower and the surface it stands on. Conversely, do not rely on the
casters to provide a conductive ground path for the tower.

T est the Stability of Custom Configurations

Changes in shelf location and loading can affect the balance of the tower. If you
arrange the shelves differently from the configuration described in this manual,
test the tower carefully for stability before using it.

Introduction

Tools

The Tektronix K475 Workstation Tower requires some assembly. This manual
tells how to assemble and use the tower.

You can assemble the K475 Workstation Tower by yourself, but it is easier if you
have another person to help you.

You will need a large flat area to assemble the tower. The area should be level
and large enough to move the various parts into place. A carpeted floor space is
ideal.

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 K475 Workstation Tower. These include a
3/16 inch Allen wrench and a circular bubble level.

Parts Identification

The large pieces of the K475 Workstation Tower 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 tower, including the
large pieces and assemblies. Take an inventory now to familiarize yourself with
the parts for the assembly process.

Base Assembly

Begin assembling the cart by joining the leg assemblies using the strut, and then
putting on the casters. You will use these parts:

H 2 Locking Casters

H 2Non-LockingCasters

H 2 Extrusions

H 2Legs

H 4 Bumpons

H 4 1/4--20 x 1-1/4 inch Screws

H 4 1 inch Fender Washers

H 13/16AllenWrench

H 41x3inchEndCaps

H 1Strut

H 4 1/2 inch Split Lockwashers

H 4 1/4--20 Button Head Screws, 1/2 inch length

H 4 1/4 inch Tooth Lockwashers

H 4 Short Rails

You will use a 3/4 inch (19 mm) wrench or adjustable wrench, and the 3/16 inch
Allen wrench included with your tower.

1. Prepare the strut as shown in Figure 3. P osition the short rail with the raised
threaded flange toward the strut. Leave each screw assembly loose; do not
screw the short rail onto the button head screw more than one full turn.

2. On each leg assembly, observe that there is a small, clear, plastic button on
the horizontal leg bar. This button is on the inside of the tower, at the back.
Position the leg assemblies as shown in Figure 4. Leave a space between the
leg assemblies about equal to the length of the strut.

Base Assembly

Pencil Marks: first line should be 10 inches
from the bottom of the extrusion. For the first
leg assembly, turn extrusion so pencil marks
are on the inside. For second leg assembly,
pencil marks are also on the inside.

Bumpons are on the
inside of the extrusions.

Clear Plastic Buttons (1 on each leg assembly)

Note: Leg tube can be crushed if screw is over
tightened; maximum torque is 3-6 foot/pounds.

Figure 4: Aligning the Leg Assemblies and the Strut

3. Orient extrusion so the end with threaded holes is on the bottom If shelf

position pencil marks are present on one of the slotted sides of the extrusion
there should be one mark 10 inches from this end. You will build two leg
assemblies, one with the extrusion oriented with pencil marks on the right
side and the second with pencil marks on the left side.

4. Place extrusion on top of leg tube oriented so the caster nuts are on the

bottom as shown in Figure 4.

5. Place long screw through washer and insert through bottom of leg tube (side
with large caster nuts) and into the extrusion. Screw will extend through top
of leg tube to receive threaded ends of extrusion. Hand tighten with hex key.

CAUTION. Leg tube can be crushed if screw is over tightened.

Max torque is 3--6 ft--lbs. Repeat for second assembly, be sure to orient
extrusion so pencil marks are on the other side.

6. Apply two bumpons to the top of each leg as shown in the illustration. They
go on the side of the extrusion with pencil marks for each assembly.

7. Install end caps into end of each leg. Don’t install end caps into extrusions.

8. Position the strut horizontally between the leg assemblies, as shown in

Figure 4, with the open side of the strut to the back. Line up the short rails
with the back groove in the leg assemblies.

9. Slide the strut down to the base of the tower, adjusting the distance between
the leg assemblies as needed. When complete, make sure the strut is resting
tight against the clear plastic buttons on the leg assemblies.

10. Use the 3/16 inch Allen wrench to tighten the button head screws. Tighten
them first snugly, then go back and tighten them firmly.

NOTE. If you have a torque wrench available, tighten these and all shelf screws
to 60 in⋅lb (6.8 N⋅m) torque.

11. Tip the tower onto its back as shown in Figure 5, resting it on the work
surface by the tops and backs of the leg assemblies.

12. Identify which casters are locking and which are non-locking. The locking
casters, which go on the front of the cart, have an extra tab that you step on
to lock the wheels.

13. On the locking casters, place a 1/2 inch split lockwasher on each threaded
shaft, then install the casters into the two front holes in the bottoms of the
leg assemblies. Tighten the casters using the wrench only until they are snug.

14. On the non-locking casters, place a 1/2 inch split lockwasher on each
threaded shaft, then install the casters into the two back holes in the bottoms
of the leg assemblies. Tighten the casters using the wrench only until they
are snug.

15. Return the tower to the upright position.
