WARNING:
Failure to properly follow maintenance instructions
and precautions can cause severe personal injury or
loss of life.
Always follow the procedures and precautions in the
instruction manual.
Safety Precautions
• Make sure the engine is off before beginning any
maintenance or repairs. This will eliminate several
potential hazards:
- Carbon monoxide poisoning from engine
exhaust.
Operate outside away from open windows or
doors.
- Burns from hot parts.
Let the engine and exhaust system cool before
touching.
- Injury from moving parts.
Do not run the engine unless instructed to do so.
• Read the instructions before you operate the generator,
and make sure you understand the instructions and
have the tools and skills required.
• To reduce the possibility of fire or explosion, be careful
when working around gasoline. Use only a non-
flammable solvent, not gasoline, to clean parts. Keep
cigarettes, sparks, and flames away from all fuel-
related parts.
Remember that your servicing dealer knows your
generator best and is fully equipped to maintain and repair
it.
To ensure the best quality and reliability, use only new,
genuine Makita parts or their equivalents for repair or
replacement.

Engine Oil Change (Fig. 15)
Drain the oil while the engine is warm to assure quick and
complete draining.
1. Place a suitable container below the engine to catch
the oil.
2. Drain the oil by removing the oil drain plug, the sealing
washer, and the oil filler cap/dipstick.
3. Reinstall the oil drain plug and a new sealing washer
and firmly tighten the plug.
4. Refill with the recommended oil and check the oil
level.
Wash your hands with soap and water after handling used
oil.
NOTICE:
Improper disposal of used engine oil can be hazardous to
the environment. Before changing the oil, check for a
suitable way to dispose of the used oil. Do not discard it in
a trash bin, pour it down a drain, or dump it on the ground.
Your local zoning or environmental regulations will give
you more detailed instructions on proper disposal.
Air Cleaner Service (Fig. 16 & Fig. 17)
A dirty air cleaner will restrict air flow to the carburetor. To
prevent carburetor malfunction, clean the air cleaner
