2.
Turn the Monitor so that you are facing the front. Note the range of
movement for each arm. The arm should rest as the left Monitor in
Figure 42 indicates, and move freely to the position shown in the right
Monitor in Figure 42 If the arm does not move freely, inspect the bearing
to see if itis contaminated.
3.
Each arm contains a molded, internal plastic step which catches ona
similar molded plastic step on the handle.
This causes the handle to
raise as the arm is raised.
4,
Repeat step 2 and raise each arm. Verify that each arm catches and
raises the handle.
if the handle does not raise with each arm, then either
the handie or the arm has a broken plastic step.
Equipment Required
+
Small jeweler's screwdriver
+
Standard screwdriver
+
9/6" socket and driver
Note:
Review the contents of the Arm replacement parts kit (see the
Replacement Parts List on page 64), to confirm which parts you
may need to keep/discard during disassembly.
Procedure
1. . Remove the arm cap by inserting a small flat head jeweler's screwdriver
between the arm cap and the arm as illustrated in Figure 43.
2.
Remove the shoulder screw to separate the arm from the enclosure as in
Figure 44.
Note:
There are two shoulder screw configurations; slotted head screw
and a hex head screw. The slotted shoulder screw is used with
a smail washer.
Keep this washer only if a hex head shoulder
screw is not available as a replacement. Use a large flat head
screwdriver for the slotted head screw and a 3/8" hex head nut
driver to remove:the hex head screw.
3.
Visually inspect the bearing to verify that there is. ne.contamination which
would cause it to bind up. If the bearing is contaminated, clean out the
bearing with either compressed air or anon abrasive cloth dampened
with 70% Isopropyl Alcohol.
If available, apply two drops. of a non-
silicone-based lubricant to the bearing:
Note:
Some oils have chemical compounds which may attack the
plastic enclosure. Use only oil/grease which will not attack the
material of the arms.
4.
Visually inspect the molded plastic steps. Item A in Figure 45 is the step
on the inside of the arm.
Item B is the step on the outside of the handle.
If either step is cracked or broken, the respective part must be replaced.
