Muffler
This machine must never be operated
with a faulty or missing spark arrester
or muffler. Make sure the muffler is well
secured and in good condition. A worn
or damaged muffler is a fire hazard and
may also cause hearing loss.
Spark Plug
Keep the spark plug and wire connec-
tions tight and clean.
Fasteners
Make sure nuts, bolts, and screws
(except carburetor adjusting screws)
are tight.
WARNING!
Before performing any mainte-
nance, repair, or cleaning work on
the machine, make sure the engine
is completely stopped. Disconnect
the spark plug wire before perform-
ing service or maintenance work.
Daily Maintenance
Prior to each work day, perform the
following:
! Remove all dirt and debris from the
engine, check the cooling fins and
air cleaner for clogging, and clean
as necessary.
! Carefully remove any accumulations
of dirt or debris from the muffler and
fuel tank. Dirt build-up in these areas
can lead to engine overheating, fire,
or premature wear.
! Check for loose or missing screws or
components. Make sure the sprayer
hose is securely fastened.
! Check the entire machine for
leaking fuel or grease.
