Cooling
Do not direct water or steam into the gen-
erator openings. Do not allow any soap and
water solutions to enter the generator.
Keep all cooling parts clean. DO NOT EXCEED TEM-
PERATURE RISE OF 80°C (176°F) ABOVE A 40°C
(104°F) AMBIENT. This ensures that the NEMA Class
"F" insulation will not be damaged. DO NOT EXCEED
RATED LOAD. OPERATE GENERATOR AT RATED
SPEED. Failure to operate generators at rated load or
speed will cause overheating and possible damage to
windings due to over voltage or current.
Drying the Generator Windings
High voltage (dielectric) testing must not
be performed on the machine without first
observing NEMA rules. The insulation of
this generator winding may be safely
checked by using a megohm meter. A high
reading indicates good insulation.
Generators of this type should not be
"flashed". Operation with external voltage
source or momentary shorting of leads will
damage the generator and may cause inju-
ry.
Generators that have been in transit, recently steam
cleaned, or in storage for long periods may be sub-
jected to extreme temperature and moisture changes.
This can cause excessive condensation, and the gen-
erator windings should be thoroughly dried out before
bringing the generator up to full nameplate voltage. If
this precaution is not taken, serious damage to the
generator can result.
The windings may be dried by placing generator in
drying oven or hot room or dry with warm air blower
directed through windings.
Removal
Be aware of HIGH VOLTAGE supplied by
the generator as the unit may start auto-
matically. Before servicing the unit, ensure
the START/RUN-OFF switch is in the OFF
position. Also disconnect the power plug
and negative battery cable. NEVER dis-
assemble the generator: HIGH MAGNETIC
FIELD INSIDE!
1. Disconnect the battery negative and then positive
terminals.
2. Disconnect the generator ground and ground strap
at the rear engine mounting channel.
3. Open the spiral wrap on the generator wires and
cut the connections on the generator side.
4. Remove the bolts from the two rear engine mounts.
