COOLING SYSTEM
Air intake and outlet openings in the generator com- partment must be open and unobstructed for contin- ued proper operation. This includes such obstruc- tions as high grass, weeds, brush, leaves and snow.
Without sufficient cooling and ventilating air flow, the engine/generator quickly overheats, which causes it to shut down. (See the installation diagram.)
The exhaust system parts from this product get extremely hot and remains hot after shutdown. High grass, weeds, brush, leaves, etc. must remain clear of the exhaust. Such materials may ignite and burn from the heat of the exhaust system.
CHECKING FLUID LEVELS
CHECK ENGINE OIL
Check engine crankcase oil level (Figure 10.3) at least every 20 hours of operation, or prior to use.
•Remove oil dipstick and wipe dry with a clean, lint- free cloth.
•Install oil dipstick, then remove again.
•Oil should be between FULL and ADD marks.
•If oil level is below the dipstick ADD mark, remove oil fill cap. Add the recommended oil to bring oil level up to the FULL mark. DO NOT FILL ABOVE THE “FULL” MARK. See “Engine Oil Recommen- dations” for recommended oils.

BATTERY FLUID
Check battery electrolyte fluid based on the Maintenance Schedule. Fluid should cover separa- tors in all battery cells. If fluid level is low, add dis- tilled water to cover tops of separators. DO NOT USE TAP WATER IN BATTERY.
OVERLOAD PROTECTION FOR ENGINE DC ELECTRICAL SYSTEM
Engine cranking, start up and running are controlled by a solid state Engine Controller circuit board. Battery voltage is delivered to that circuit board via a 15 amp fuse. These overcurrent protection devices will open if the circuit is overloaded.
If a circuit breaker opens or a fuse element melts, find the cause of the overload before resetting the circuit breaker or replacing the fuse.
ENGINE COOLANT
Check coolant level in coolant recovery bottle. See Specifications.
•Add recommended coolant mixture as necessary.
•Periodically remove radiator pressure cap (only when engine has cooled down) to make sure the coolant recovery system is functioning properly. Coolant should be at bottom of radiator filler neck. If coolant level is low, inspect gasket in radiator pressure cap. Replace cap, if necessary. To have pressure cap tested, contact an Authorized Service Dealer. Inspect cooling system and coolant recov- ery system for leaks.
