900W Generator
Check the cleanliness of the generator frequently and clean when dust, dirt, oil, moisture or other foreign substances are visible on its exterior surface.
•Remove the oil fill cover and clean area around oil drain plug (Figure 12).
Figure 12 — Oil Drain Plug
NOTE: DO NOT use a garden hose to clean generator. Water can enter engine fuel system and cause problems. In addition, if water enters generator through cooling air slots, some of the water will be retained in voids and cracks of the rotor and stator winding insulation. Water and dirt buildup on the generator internal windings will eventually decrease the insulation resistance of these windings.
To Clean the Generator
•Use a damp cloth to wipe exterior surfaces clean.
•Soft, bristle brush may be used to loosen caked on dirt or oil.
CAUTION! NEVER insert any object or tool through the air cooling slots, even if the engine is not running.
•A vacuum cleaner may be used to pick up loose dirt and debris.
•Low pressure air (not to exceed 25 psi) may be used to blow away dirt. Inspect cooling air slots and opening on generator. These openings must be kept clean and unobstructed.
WARNING! When working on the generator always disconnect spark plug wire from spark plug and keep it away from spark plug.
Oil Drain Plug |
•Remove oil drain plug, sealing washer, and oil filler cap. Drain oil completely into a suitable container.
•Install oil drain plug and sealing washer. Tighten securely.
•Refill with recommended oil and check the level. See page 6 for oil recommendations.
•Wipe up any spilled oil.
CAUTION! Avoid prolonged or repeated skin contact with used motor oil. Used motor oil has been shown to cause skin cancer in certain laboratory animals. Thoroughly wash exposed areas with soap and water. KEEP OUT OF REACH OF CHILDREN.
DON'T POLLUTE. CONSERVE RESOURCES. RETURN USED OIL TO COLLECTION CENTERS.
• Replace oil fill cover.
ENGINE MAINTENANCE
Checking Oil Level
Oil level should be checked prior to each use or at least every 5 hours of operation. Keep oil level maintained.
Changing Engine Oil
Change the oil after the first month of operation, then every 25 hours. If you are using your generator under extremely dirty or dusty conditions, or in extremely hot weather, change the oil more often.
Change the oil while the engine is still warm from running, as follows:
Clean/Replace Spark Plug
Check and clean the spark plug every 50 hours of operation or every three months, whichever comes first. This will help your engine to start easier and run better.
•Remove spark plug access cover. Remove spark plug cap.
•Clean the area around the spark plug.
•Remove and inspect the spark plug.
•Replace the spark plug if electrodes are pitted or burned or the porcelain is cracked. Use recommended plug for replacement.
•Check electrode gap with wire feeler gauge and set spark plug gap between 0.028 and 0.031 inch (0.7 to 0.8 mm) if necessary (Figure 13).
