tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which can result in serious personal injury.
SPARK PLUG
This engine uses a Champion RCJ4 or equivalent spark plug
with .025 in. electrode gap. Use an exact replacement and
replace annually, or more frequently if necessary.
NOTICE:
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product.
CLEANING THE EXHAUST PORT
NOTICE:
The spark arrestor on this product has not been evalu-
ated by the USDA Forest Service and cannot be used on
U.S. forest lands. In addition, product users must comply
with Federal, State, and local fire prevention regulations.
Check with appropriate authorities. Contact customer
service to purchase a replacement spark arrestor.
NOTE: Depending on the type of fuel used, the type and
amount of lubricant used, and/or your operating conditions, the
exhaust port, muffler, and/or spark arrestor screen may be-
come blocked with carbon deposits. If you notice a power
loss with your gas powered tool, you may need to remove
these deposits to restore performance. We highly recommend
that only qualified service technicians perform this service.
