Caterpillar: Confidential Green
Generator - Inspect
Once a month start the engine and run the engine
until it reaches normal operating temperature (about
10 minutes). Plug in a corded device and turn on the
device to ensure that the generator is providing
power. Once you have verified that the generator is
providing power, turn off the device and unplug it.
Then turn the generator off.
Air Filter – Check
A dirty air filter will restrict air flow into the carburetor,
will cause poor fuel economy, and may damage the
engine. To keep the generator in good operating
condition, service the air filter regularly. Service more
frequently when operating the generator in extremely
dusty areas.
Note: Never operate the generator without the air
filter in place. Operating the generator without the air
filter in place will result in rapid engine wear.
To access the air filter, follow the procedure for
Battery Connection in the FIRST USE
INSTRUCTIONS.
1. To access the air filter foam and paper elements,
unclip the 2 fasteners (1).
2. Gently remove the air filter cover. Note, the
paper element should be removed with the
cover.
Inspect the paper element for cleanliness. If the paper
element is dirty, replace it.
Inspect the foam element. If the foam element is dirty,
wash the element. If the foam element is damaged,
replace it.
Use nonflammable solvent or a mixture of household
detergent and warm water to wash the filter. Rinse the
filter thoroughly to remove all of the cleaning solution.
Replace the filter after the filter has dried. DO NOT oil
the foam filter.
Note: Do not wring out the filter. Wringing out the filter
may damage the filter.
Use a damp rag to wipe dirt from the case and cover.
Install the filter into the housing. Replace the air filter
door and side panel in the reverse procedure to
removal.
Cylinder Head - Clean
Only qualified service personnel should perform this
maintenance procedure. Contact your local service
center to schedule this maintenance.
Engine Oil Level – Check
Always check the engine oil with the generator on a
level surface and with the engine stopped.
1. Open the service access door and remove the oil
level gauge (1) and wipe clean.
2. Check the oil level by re-inserting the oil level
gauge (do not screw in tight).
3. If the oil level is low (3), add the recommended
engine oil, using the funnel supplied, until the oil
level reaches the upper mark (2) on the oil level
gauge. Use the chart below to determine which
viscosity oil to use.
4. After adding oil, install and tighten the oil level
gauge (1) and close the service door.
Note: Non-detergent and 2-stroke engine oils will
damage the engine and must not be used.
