3.11 MISCELLANEOUS MAINTENANCE
# 5.11.1 CLEANING THE GENERATOR_____________
Keep your generator as clean and as diy^ as possi­
ble. Dirt and moisture that accumulate on internal
generator windings have an adverse effect on insu­
lation resistance.
Periodically, clean the generator’s exterior surfaces.
soft brush may be used to loosen caked on dirt.
You can use a vacuum system or clr/, low pressure
air to remove any accumulations of dirt. The gener­
ator is housed inside an all-weather enclosure:
clean the enclosure with a soft, damp cloth or
sponge and water.
Once each year, have tlie generator cleaned and
inspected
t3V a Generac/Guardian Authorized
Dealer. Sertdce technicians wall use diy, low pres­
sure air to clean internal windings. Parts Inside the
control console should be cleaned and inspected at
this time as w^ell.
F'ina.lly, have the insulation resistance of stator and
rotor wdndings checked. If insulation resistances are
excessively low. the generator may require diydng.
^ 3.11.2 RODENT PROTECTION____________________
The intrusion of rodents into the generator set can
cause a wide range of problems, from failure of the
unit to start, to personal injury and, in extreme cir-
cumsta.nces, short circuit or fire. .Although the unit
wms designed to limit this problem, you can take
further precautions to help minimize both the
chance of rodent entry and the extent of any dam­
age, You should inspect the unit at regular inter­
vals for signs of rodent intrusion. In addition,
ensure that all access doors are tightly closed and
secured at all times. If you detect intrusion and/or
damage, contact your nearest Generac Authorized
Service Dealer immediately.

5. While ttie engine is still warm from n.m,ning, drain
the oil completely. Reiill the cranitcase witli the
recommended oil (see Section 1.9, Page 7).
6. Attach a tag to tlie engine indicating the viscos­
ity and classification of the oil in the crankcase.
7. Remove the battery and store it in a cool, dry
room on a wooden boa.rd. Never store the bat-
ter>' on any concrete or earthen floor.
8. Clean and wipe the entire generator.

as follows:
1. Verify that utility' power is turned off to the
transfer switch and that the Auto/Off/Manual
switch is set to OFF.
2. Check the tag on the engine for oil viscosify and
classi,fication. Verify that the correct recom­
mended oil is used in engine (see Section 1.9.
Page 7). If necessa.r>i clradn and refill with the
proper oil.
3. Check the barterv. Fill all ceils to the proper
level witli distilled water. DO NOT USE TAP
WATER IN THE BATTERY. Remove the batteiy
before charging. Recharge the batteiy' to 100
percent state of charge, or. if defective, replace
the batteiy' with a 12-volt DC Group 26F battery
rated for 75 amp hours (part # 77483).
4. Clean and wipe the entire generator.
5. Reconnect the battery. Obsen'e battery pokirity.
Damage will occur if tlie battery is connected
incorrectly.
6. Open the fuel shutoff valve.
