| Start the generator engine at least once every seven |
Oil Fill Cap | days and let it run at least 20 minutes. See “Weekly |
| Exercise Cycle”. |
| INSPECT COOLING SYSTEM | |
Oil | • Inspect engine cooling system. See “Maintenance | |
Dipstick | Schedule”. | |

| ||
| Correct any discrepancies found. | |
| • Check hose clamps for tightness. |
CHECK ENGINE COOLANT LEVEL
See “Checking Fluid Levels”.
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.
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.

CHECK ENGINE OIL LEVEL
Refer to “Checking Fluid Levels”.
CHECK BATTERY
•See “Checking Fluid Levels”.
•Check battery cables for condition, tightness, cor- rosion or damage. Clean, tighten or replace as necessary.
PERFORM VISUAL INSPECTION
Complete a thorough visual inspection of the entire
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.
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.
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 incor- rect frequency and/or voltage. Only qualified service technicians should adjust the governed speed.
