4.6OVERLOAD PROTECTION FOR

Section 4 — Maintenance

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.

4.6OVERLOAD 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.

Liquid-cooled 25 kW Generators

‹4.7.2 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.

‹4.7.3 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.

4.7CHECKING FLUID LEVELS

‹4.7.1 CHECK ENGINE OIL

Check engine crankcase oil level (Figure 4.3) 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.

‹4.8.1 CHECK ENGINE OIL LEVEL

Refer to “Checking Fluid Levels”.

‹4.8.2 CHECK BATTERY

See “Checking Fluid Levels”.

Check battery cables for condition, tightness, cor- rosion or damage. Clean, tighten or replace as necessary.

‹4.8.3 EXERCISE SYSTEM

Start the generator engine at least once every seven days and let it run at least 12 minutes. See “Weekly Exercise Cycle”.

‹4.8.4 INSPECT COOLING SYSTEM

Inspect engine cooling system. See “Maintenance Schedule”.

Check hoses for damage, deterioration, leaks, etc. Correct any discrepancies found.

Check hose clamps for tightness.

‹4.8.5 CHECK ENGINE COOLANT LEVEL

See “Checking Fluid Levels”.

‹4.8.6 PERFORM VISUAL INSPECTION

Complete a thorough visual inspection of the entire engine-generator monthly. Look for obvious damage, loose, missing or corroded nuts, bolts and other fas- teners. Look for fuel, oil or coolant leaks.
