Section 4 — Maintenance

Liquid-cooled 15, 20 and 25 kW Generators

‹ 4.7.2 BATTERY FLUID

 

‹ 4.8.6 PERFORM VISUAL INSPECTION

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.

4.8MAINTENANCE OWNER/ OPERATOR CAN PERFORM

‹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”.

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.

‹4.8.7 INSPECT EXHAUST SYSTEM

Inspect the exhaust system at least once every three months. Check all exhaust system pipes, mufflers, clamps, etc. for condition, tightness, leaks, security, damage.

‹4.8.8 CHECK FAN BELT

•Inspect fan belts every three months. Replace any damaged, deteriorated, worn or otherwise defec- tive belt.

•Check fan belt tension. Thumb pressure, exerted midway between pulleys, should deflect about 3/8 to 5/8 of an inch. Adjust belt tension as required.

‹4.8.9 INSPECT ENGINE GOVERNOR

Visually inspect electronic governor.

DANGER

Do not attempt to adjust the governor. Only

!qualified service facilities should adjust the governor. Excessively high operating speeds are dangerous and increase the risk of personal injury. Low speeds impose a heavy load on the engine when adequate engine power is not available and may shorten engine life. Correct rated frequency and voltage are supplied only at the proper governed speed. Some connected electrical load devices may be damaged by incorrect frequency and/or voltage. Only quali- fied service technicians should adjust the gov- erned speed.

‹4.8.10 CHANGING ENGINE OIL

Refer to maintenance performed by authorized service facilities for engine oil and filter change frequencies.

Drain the oil while the engine is still warm from run- ning. This means warm up the engine, shut it down and drain immediately as follows:

1.Remove OIL DRAIN HOSE from its retaining clip.

2.Loosen and remove OIL DRAIN HOSE CAP. Drain oil completely into suitable container.

3.When all oil has drained, install and tighten OIL DRAIN HOSE CAP, and re-install into its retaining clip.

4.Turn OIL FILTER (Figure 4.1) counterclockwise and remove. Properly dispose of old filter.
