3.1 Power Unit Set Up and Adjustment for Opera-
tion
3.1.1
Remove the handhole cover.
3.1.2
Lift the portable drive motor to the handhole and
slide its square support bracket into the power unit
support bracket on the winch mounting plate. Align
holes in the tubes and install the snap-lock pin through
the tubes. Be sure to engage the snap-lock over the
end of the pin. (See Figure 26)

SECTION III
OPERATING INSTRUCTIONS
EVERY PERSON WHO INTENDS TO OPERATE THE LOWERING DEVICE SHOULD READ COMPLETELY
AND UNDERSTAND FULLY THESE INSTRUCTIONS BEFORE OPERATING THE DEVICE.
3.1.3
Check alignment and fit of the portable drive motor
drive coupling onto the winch input shaft. During the first
operation of the power unit on a new pole installation, it
may be necessary to adjust the alignment by loosening
the nuts holding the power unit support bracket and/or
the winch, moving them slightly and then tightening all
nuts securely. This should be done to insure that the
centerlines of the winch and the power unit drive shaft
are parallel and the coupling slides squarely onto the
3.0 General Comments
3.0.1
The portable drive motor is provided with a twenty
foot long remote control cord and switch. This permits
the operator to stand a safe distance from the pole
while operating the device.
WARNING
Operate the lowering device only while standing at the
maximum distance from the pole allowed by the twenty
foot long remote control cord. Failure to follow this
procedure may result in injury or death.
3.0.2
The Holophane portable drive motor is supplied
with two built-in safety features which are incorporated
to prevent excessive torque from being applied to the
winch input shaft. These are:
a.
a factory-set torque limiting clutch,
b.
a shear pin which breaks below a predetermined
torque limit, higher than the torque limiting clutch
setting.
These two torque limiting features are for the protection
of both equipment and operating personnel.
WARNING
Do not expose the torque limiter or shear pin to damag-
ing elements or mistreatment such as sand, mud, salt
spray or other conditions which could render either
safety mechanism inoperable. Do not attempt to adjust
the torque limiting clutch or replace the shear pin. If
repairs are necessary, replace damaged equipment
with replacement components from Holophane. Failure
to follow these warnings may result in injury or death.
3.0.3
If the shear pin breaks, call Holophane at (740)
345-9631 and ask for the Field Service Department.
(See Paragraph 4.3 for the torque limiter assembly
replacement)
3.0.4
If the torque limiter releases before the mounting
ring reaches the top of the pole, this is an indication
that either there is something causing the lowering
device to require an abnormally high lift force to operate
or that the clutch is releasing at an abnormally low
torque level. Carefully try to determine if there is some-
thing wrong with the lowering device that is causing an
abnormally high input torque requirement. A couple of
possible problems are as follows and can be checked
