The control panel fuse has been removed from the control box.

The 120VAC supply to the battery charger is switched OFF.

The negative battery cable has been removed.

CHECK ENGINE OIL

Check engine crankcase oil level (Figure 10.1) according to the Service Schedule and SIB10-10-L24G.

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 Recommendations” for recommended oils.

CHANGING ENGINE OIL

nHot oil may cause burns. Allow engine to cool before draining oil. Avoid prolonged or repeated skin exposure with used oil. Thoroughly wash exposed areas with soap.

Refer to the Service Schedule for engine oil and filter change fre- quencies.

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

1.Remove the drain hose from its retaining clip or cut the zip-tie securing the oil drain hose.

2.Loosen and remove OIL DRAIN HOSE CAP. Drain oil com- pletely into suitable container.

3.When all oil has drained, install and tighten OIL DRAIN HOSE CAP and secure drain hose with a new zip-tie, or place the hose in its retaining clip.

4.Turn OIL FILTER (Figure 10.1) counterclockwise and remove. Properly dispose of old filter.

5.Apply light coating of new engine oil to seal of new oil fil- ter. Install FILTER and tighten by hand only. DO NOT OVER TIGHTEN.

6.Remove OIL FILL CAP and add recommended oil. Crankcase oil capacity is listed in the "Specifications" section.

nAfter refilling the crankcase with oil, always check oil level on dipstick. NEVER OPERATE ENGINE WITH OIL BELOW THE DIPSTICK “ADD” MARK.

7.Start engine and check for oil leaks.

8.Shut OFF engine and wait 10 minutes for the oil to settle down into the oil pan. Recheck oil level on dipstick. DO NOT fill above the dipstick "FULL" mark.

9.Dispose of used oil at a proper collection center.

COOLING INTAKE/OUTLET

Air intake and outlet openings in the generator compartment must be open and unobstructed for continued proper operation. This includes such obstructions as high grass, weeds, brush, leaves and snow.

Without sufficient cooling and ventilating air flow, the engine/gen- erator 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.

INSPECT COOLING SYSTEM

Inspect engine cooling system. See the Service Schedule.

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

Check hose clamps for tightness.
