WARNING:
Use only Toro replacement parts when servicing
this product. Use of any other parts may create a
hazard or cause product damage.
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 conditions,
the exhaust port and mufer may become blocked with
carbon deposits. If you notice a power loss with your
gas powered tool, you may need to remove these depos-
its to restore performance. We highly recommended that
only qualied service technicians perform this service.
Servicing the Product
■ Check and tighten all fasteners. If any part is damaged
or lost, repair it or replace it.
