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.

Your local zoning or environmental regulations will give
you more detailed instructions on proper disposal.
