QUIETPACT™ 75D Recreational Vehicle Generator
Be sure to reinstall the hex pipe cap tightly to the spark arrestor cleanout pipe. Vibration could cause a loose cap to fall out, resulting in hot engine exhaust being drawn through the centrifugal cooling fan and out beneath the unit. This could result in damage to the genera- tor or in discharge of hot exhaust sparks beneath the unit.

3.5CLEANING THE GENERATOR
Keep the generator as clean and as dry as possible. Dirt and moisture that accumulate on internal gener- ator windings have adversely affect insulation resis- tance.
Periodically, clean the generator’s exterior surfaces. A soft brush may be used to loosen
Once each year, have the generator cleaned and inspected by a Generac Authorized Service Dealer. Service technicians will use dry,
Finally, have the insulation resistance of stator and rotor windings checked. If insulation resistances are excessively low, the generator may require drying.
Do NOT use a forceful spray of water to clean
!the generator. Water will enter the generator interior and cause problems, and may also contaminate the generator fuel system.
3.6BATTERY MAINTENANCE
All
•Inspect the battery posts and cables for tightness and corrosion. Tighten and clean as necessary.
•Check the battery fluid level of unsealed batteries and, if necessary, fill with Distilled Water Only. Do not use tap water in batteries.
•Have the state of charge and condition checked by a Generac Authorized Service Dealer.
NOTE:
Servicing of the battery is to be performed or supervised by knowledgeable personnel, accord- ing to the required precautions. Keep unautho- rized personnel away from batteries.
Damage will result if the battery connections are made in reverse.
DANGER
Do not dispose of the battery in a fire. The battery is capable of exploding. Storage batter- ies release explosive hydrogen gas. This gas can form an explosive mixture around the battery for several hours after charging. The slightest spark can ignite the gas and cause an explo- sion. Such an explosion can shatter the battery and cause blindness or other injury. Any area that houses a storage battery must be properly ventilated. Do not allow smoking, open flame, sparks, or any
A battery presents a risk of electrical shock and high
•Remove watches, rings, and other metal objects;
•Use tools with insulated handles;
•Wear rubber gloves and boots;
•Do not lay tools or metal parts on top of the battery;
•Disconnect any charging source prior to connect- ing, or disconnecting, battery terminals; and
•Do not use any jumper cables or booster battery to crank and start the generator engine. If any bat- tery has discharged, remove it for recharging.
