Power Unit Servicing (Electric Motor)
1. Out-of-Service Protection (30 days or more)
A. Wipe entire unit to remove all dirt, etc.
B. Provide a suitable cover over the entire unit.
C. Make sure all electrical connections are
disconnected to prevent accidental starting.
D. Priming if needed:
Tilt unit and jog motor unit (switch down)
several times - allow motor to idle to a
complete stop between "jogs". Return unit to
an upright position. Switch to the "run"
position (switch up) and allow unit to operate
for about five (5) minutes. The foregoing
steps are essential to prime the high
pressure pistons.
2. Temperature Protection
A. See that nothing obstructs the air flow
around the motor and pump.
B. Keep motor clean (internal and external) for
maximum cooling.
C. In areas of high temperature, it may be
necessary to provide additional cooling.
Install an air cooled heat exchanger available
from your GB Distributor.
