Section 3 — Maintenance
Guardian
CAUTION: After refilling the crankcase with oil, always check oil level on dipstick. NEVER OPERATE ENGINE WITH OIL BELOW THE DIP- STICK “ADD” MARK.
7.Start engine and check for oil leaks.
•Battery electrolyte fluid is an extremely caustic sulfuric solution that can cause severe burns. DO NOT permit fluid to contact eyes, skin, clothing, painted surfaces, wiring insulation, etc. If you spill any battery fluid, flush the affected area with clear water immediately.
COOLANT CHANGE
Every year, have Authorized Service Facility drain, flush and refill the cooling system. See SPECIFICATIONS (page 7) for cooling system recommendations.
MISCELLANEOUS MAINTENANCE
CLEANING THE GENERATOR
•Always wear safety glasses, rubber apron and gloves when handling a battery.
•Batteries give off explosive hydrogen gas while charging. The gas can form an explosive mixture around the battery for several hours after charging. Any spark, heat or flames can ignite the gas and cause an explosion which can shatter the battery, causing blindness or other serious injury.
Keep your generator as clean and as dry as possible. Dirt and moisture that accumulates on internal genera- tor windings have an adverse effect on insulation resist- ance.
Periodically clean generator exterior surfaces. A soft brush may be used to loosen caked on dirt. You can use a vacuum system or dry, low pressure air to remove any accumulations of dirt. The generator is housed inside an
Once each year have the generator cleaned and inspect- ed by an Authorized Service Facility. That facility will use dry, low pressure air to clean internal windings. Parts inside the control console should be cleaned and inspected at this time as well.
Finally, have the insulation resistance of stator and rotor windings checked. If insulation resistances are excessively low, the generator may require drying.

BATTERY REPLACEMENT
Generac uses these different types of vented batteries on units ranging up to 400 kW. When replacing batteries, use the same number and the type of battery that follows:
Generac P/N | BCI Group No. | CCA |
58665 | 27F | 700 @ 0 deg. F |
61915 | 4DLT | 810 @ 0 deg. F |
61104 | 8D | 1155 @ 0 deg. F |
Note:
The BCI number should be located directly on the battery. For more information, see “Specifications.”

•DO NOT use jumper cables and a booster battery to crank or start the generator engine.
•DO NOT recharge a weak battery while it is installed in the generator. Remove battery from generator and recharge in a
