CONTENTS INDICATOR
5-6 Service and Repair
1. Remove side cover "B" (Section 5.2.1, steps 1 and 2).
2. Use a small screwdriver or awl to remove the outermost E-clip 8 from the pivot
shaft 7. Remove the pivot shaft.
Some older models may contain hitch pins in place of the E-clips. If the unit has
hitch pins, it will also contain a different pivot shaft.
Remove the carrying strap 7 (Figure 6-1 or 6-2) from the Portable.

Service
Service to the carrying strap consists of replacing the shoulder pad 8 (Figure 6-1 or 6-2)
only.
Installation
Install the carrying strap by reversing the removal procedure (Section 5.4.1).
•
Install the carrying strap so the patient can easily snap the buckle together without
twisting the strap. Both buckles should point to the center of the loop created by the
strap.
•
Make sure that the large-loop end of the strap fits completely around the side cover
screw boss.
•
Make sure the E-clip is fully engaged in the groove of the pivot shaft before closing
the unit.
The contents indicator mechanism on the Companion 1000/T is a mechanical, spring-
balanced weight scale that measures the liquid contents in the unit. The needle on the
weight scale mechanism deflects an amount proportional to the amount of liquid in the
unit. The weight scale mechanism is activated by suspending the unit from the end of
the shoulder strap closest to the indicator. The contents indicator weight scale
mechanism mounts to the standoffs in the manifold by means of four socket head cap
screws. A tab on the weight scale mechanism is also clamped in place between the side
covers.
Incorrect contents indication hazard. The contents indicator
assemblies are not interchangeable between the Companion 1000 and
the Companion T. Doing so will result in incorrect contents readings.
The contents indicator assembly on the Companion T can be identified by the
word "Transport" that appears on the indicator dial. Also, the Companion T
contents indicator uses a spring spacer
mounting bracket (Figure 6-3).
