7.1 Adjusting Counterbalance
The VHM-PL arm is shipped in its upmost position (top of
height adjustment range) –be sure it is still in this position
before proceeding. The Arm must be unlocked to perform
the counterbalance adjustment. This is done by pulling the
handle grip and inserting a 1/8” hex wrench into the handle
grip holes as shown. When grip is released, the hex wrench
will stay in position and hold the handle grip in the un-lock
position (the arm will freely move up and down). Remove
hex key after completing counterbalance adjustment.
Installation Note: VHM-PL (locking)
7.0 Adjusting the Arm
Counterbalance Adjustment –The Counterbalance Adjustment Screw is located under the Arm in front of the rear pivot
assembly. Grasp the mounted device or handle (making sure the hex wrench does not fall out) and move the Arm to a level
horizontal position. Using a 5/32” hex wrench, tighten (+) or loosen (-) the Counterbalance Adjustment Screw.
Counterbalance is correctly adjusted when the mounted device can be moved up or down with minimal force and does not
rise or fall after releasing the Arm.
Installation Note: Adjustments are factory pre-set. However, adjustments to counterbalance, tilt tension, swivel tension,
and pivot tensions may all be required to achieve optimal arm performance. Detailed instructions for making adjustments
follow in the section below. When properly adjusted the mounted device will move easily throughout the arms full range of
motion. Refer to the Routine Maintenance Check List in Section 11 for a quick guide to these functional checks.
Caution: The counterbalance procedure is performed with the device(s) and accessories installed on the Arm.
When unlocking the arm to perform the counterbalance procedure, use caution as it may be necessary to
support the weight of the arm/mounted device(s). This process may require an additional person. Use caution
while performing this procedure.

8.0 Cable Management
Cable Routing
Cables are routed from the front of the Arm to the Channel to provide an organized installation. Proper
installation of the cabling will ensure the Arm operates correctly through its full range of motion and that
there are adequate service loops for the cables to avoid damage to cables or the mounted device.
Cables are anchored at the front of the Arm (after service loop to device is determined), routed into the
Cable Cover, then anchored at the rear pivot of the Arm.
Parts included for cable routing:
Cable Sleeves: 2 Length: 30.5” (77.5cm)
Cable Ties: 8
Cable Cover
Cable Sleeve
Four (4) Cable Anchors are provided at the front
and four (4) at rear of the arm to secure cables
and create the correct service loop. Cables are
secured to the anchor points using plastic cable
ties (an initial supply is included with the Arm).
If replacement cable ties are required, standard
commercial cable ties can be used.
Two (2) Cable Sleeves are provided to assist in
determining the correct service loop and to help
protect /organize the cables as the Arm is moved
throughout its range of motion. Each Cable Sleeve
will hold three (3) small cables or one (1) large
and one (1) small cable. Use of the Cable Sleeves
is optional. Information on cable routing with and
without Cable Sleeves follows.

Service Loop 1
Determine Cable Service Loop and Route Cables with Cable Sleeves
Identify all cables that need to route through the Arm to the Channel
and ensure they are long enough. Connect all cables to the device and
organize cables so cables on the left side of the device route to the left
side anchor points and cables from the right side of the device route to
the anchor points on right side of the arm. Two Cable Sleeves are
included –they are 30.5” (77.5cm) in length and determine the correct
service loop for the cables from the front cable anchor point to the rear
cable anchor point (Service Loop 2).
Insert cables into Cable Sleeves (see diagram below). Determine the
service loop needed for the cables from their connections on the device
to the front anchor points (Service Loop 1) –do this by tilting the device
all the way forward and being sure there is adequate length to avoid
damage to a connector or unintended disconnection of a cable.
Insert cables into sleeve
Cable Sleeve must have a 1/4 rotation overlap minimum.
CAUTION: Cable sleeve material other than that supplied with the arm (or equivalent) should not be used
without verification of function by GCX.
Once Service Loop 1 to the front anchor points is determined, adjust the
Cable Sleeve and secure cable bundle to Cable Anchor with cable tie
1/2” (13mm) from the end of the Cable Sleeve. Before securing the
cable tie, ensure the service loop to the device is still correct, then
secure cables by pulling on the cable tie until the cable bundle does not
move. Position the female receptacle of cable tie against the Arm before
tightening. Use of pliers may assist in providing enough cable tie tension
on the cable bundle. Clip excess length of the cable tie as flush as
possible to avoid creation of a sharp edge.

If routing cables downward from the rear of the Arm, proceed to
Section 9 Installing Pivot Covers.
If routing cables upward from the rear of the Arm, it is necessary to
wrap the cable around the Slide before routing upward to ensure
cables will fit inside the Rear Pivot Covers (Section 9). Cables from Left
side are routed up the Right side of the Slide. Cables from the Right
side are routed up the Left side of the Slide
For cables routed without a Cable Sleeve, it is necessary to set
the proper service loop (Service Loop 2) from the front Cable
Anchor point to the rear Cable Anchor point after securing the
cables to the front Cable Anchor points (and already determining
Service Loop 1 from device to front anchor points). The correct
length for Service Loop 2 = 29.5”/75cm.
Determine Cable Service Loop and Route Cables without Cable Sleeve
Position the female receptacle of
cable tie against the Arm before
tightening. Clip excess length of the
cable tie as flush as possible to
avoid creation of a sharp edge.
Verify Service Loop 2 by pivoting the arm all the way to the
LEFT and all the way to the RIGHT to ensure cables do not
bind. Follow steps on Page 12 for installation of Cable
Cover.

10.0 Channel Cover Installation
The Arm may be cleaned with most mild, non-abrasive solutions commonly used in the hospital environment (e.g. diluted
bleach, ammonia, or alcohol solutions).
The surface finish will be permanently damaged by strong chemicals and solvents such as acetone and trichloroethylene.
Steel wool or other abrasive material should never be used.
Damage caused by the use of unapproved substances or processes will not be warranted. We recommend testing any
cleaning solution on a small area of the arm that is not visible, to verify compatibility.
Never submerge or allow liquids to enter the arm. Wipe any cleaning agents off of the arm immediately using a water-
dampened cloth. Dry the arm thoroughly after cleaning.
CAUTION: GCX makes no claims regarding the efficacy of the listed chemicals or processes as a means for controlling
infection. Consult your hospital’s infection control officer or epidemiologist. To clean or sterilize mounted instruments or
accessory equipment, refer to the specific instructions delivered with those products.
