Cleaning the Product

■
Stop the product before cleaning.
■
Clean the exterior of the product with a damp cloth.
■
Avoid using solvents when cleaning plastic parts.
Most plastics are susceptible to damage from various
types of commercial solvents and may be damaged by
their use.
■
Wipe or scrape the trimmer head and spool area
when they accumulate dirt or clippings.
■
Scrape debris away from air intake vents on both
sides of the motor housing.
CAUTION:
Keeping air intake vents free of grass and debris
prevents motor overheating and possible failure.
Note: Depending on the type of fuel used, the type
and amount of oil used, and/or your operating con-
ditions, the exhaust port and muffler may become
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 recommended that only qualified service tech-
nicians perform this service.

Servicing the Product

■
Check and tighten all fasteners. If any part is
damaged or lost, repair it or replace it.
