3.11 SERVICE AND ADJUSTMENTS
Do NOT use a forceful spray of water to clean
!the generator. Water will enter the generator interior and cause problems, and may also contaminate the generator fuel system.
3.10 BATTERY
All
◆3.10.1 ONCE WEEKLY
Inspect battery posts and cables for tightness, corro- sion. Clean and/or tighten as necessary.
Also check battery fluid level, and, if necessary, fill with DISTILLED WATER ONLY. DO NOT USE TAP WATER IN BATTERY.
◆3.10.2 EVERY SIX MONTHS
Have the battery state of charge and condition checked by an automotive service facility. This should be done with an automotive type battery hydrometer.
DANGER
Storage batteries give off explosive hydrogen gas. This can form an explosive mixture around the battery for several hours after charging. The slightest spark can ignite the gas and cause an explosion. Such an explo- sion can shatter the battery and cause blind- ness or other injury. Any area that houses a storage battery must be properly ventilated. Do not allow smoking, open flame, sparks or any spark producing tools or equipment near the battery.
Battery electrolyte fluid is an extremely caus-
!tic sulfuric acid solution that can cause severe burns. Do not permit fluid to contact eyes, skin, clothing, painted surfaces, etc. Wear pro- tective goggles, protective clothing and gloves when handling a battery. If fluid is spilled, flush the affected area immediately with clear water.
Do not use any jumper cables or booster bat-
!tery to crank and start the generator engine. If any battery has discharged, remove it from the vehicle for recharging.
◆3.11.1 ENGINE SPEED
Engine speed is completely
NOTE:
The computer will disable the electrical load capabilities of the generator and enter a fault con- dition if the throttle is accelerated manually or any other way.
3.12 ADJUSTING THE CARBURETOR
The carburetor of the generator is preset at the facto- ry. The carburetor should not be tampered with, as this will void the emission control system warranty. If the generator is used at altitudes in excess of 5,000 feet, consult the Generac Authorized Service Facility regarding high altitude jetting changes.
3.13 ADJUSTING VALVE CLEARANCE
After the first 50 hours of operation, adjust the valve clearance in the engine.
When adjusting valve clearance, the engine should be at room temperature and the piston should be at Top Dead Center (TDC) of its compression stroke (both valves closed). Correct clearance is
1.Loosen the rocker arm jam nut. Use an allen wrench to turn the pivot ball stud while checking clearance between the rocker arm and the valve stem with a feeler gauge (Figure 3.8).
