A. Cleaning
The generator may be cleaned by careful use of compressed air and/or a good, SAFE commercial
cleaner. Steam cleaning of the generator is no longer recommended because the use of steam and
harsh chemical compounds may damage insulation and other generator components.
WARNING: ELECTRIC SHOCK AND FIRE CAN KILL OR INJURE! BE SURE THE
UNIT IS COMPLETELY DRY BEFORE OPERATING. DO NOT USE A FLAMMA-
BLE SOLVENT.
B. Adjustment
The generator itself requires no adjustment. Adjustment procedures for generator controls will be cov-
ered in Section 2-3.
8. Drive Belts
Twin belts from the crankshaft pulley are used to drive the alternator and water pump. For proper en-
gine operation these belts should be in good condition and at proper tension at all times.
A. Checking Belt Tension
Check belt tension every 200 hours of engine operation, or bi-weekly. Belts which are too tight are de-
structive to bearings of the alternator and water pump. A loose belt will slip and cause inefficient op-
eration of the alternator and/or the water pump.
To check belt tension, press each belt firmly with the thumb at a point halfway between the alternator
pulley and the crankshaft pulley. A properly adjusted belt should deflect about 3/8 inch.
B. Belt Adjustment
To adjust belt tension, loosen the alternator mounting bolts and change the position of the alternator.
Upon obtaining the correct tension, re-tighten both alternator mounting bolts.
When new belts are fitted, it is necessary to run the engine for a short period to allow the new belts to
settle into the grooves of the pulleys and thus show any initial stretching that is going to occur. Re-
check belt tension after running the engine and adjust as necessary. Twin drive belts should be
changed in pairs.
9. Trailer, Truck and Battery Maintenance
If the generator set comes with either the trailer or truck option, refer to Chapter 5 for the number of the
manual which covers the particular option. The manual referred to will provide the appropriate mainte-
nance procedure. Both manuals cover battery maintenance, as, when either option is used, the batteries
are installed within it.
10. Service Helps
A. Wiring
All small wire leads are routed through plastic flexible conduit which protects them and makes a neat
easily removable and replaceable wiring harness arrangement. This wiring method allows the replace-
ment of a single wire lead with a minimum of difficulty. All wires are color coded.
