■ MUFFLER

• Inspect periodically, the muffler for loose fasteners,

any damage or corrosion. If any sign of exhaust
leakage is found, stop using the machine and have it
repaired immediately. 

■ SPARK ARRESTER
• The muffler is equipped with a spark arrester to

prevent red hot carbon from flying out of the exhaust
outlet. Periodically inspect and clean as necessary
with a wire brush. 
In the State of California it is required by law
(Section 4442 of the California Public Resources
Code) to equip a spark arrester when a gas powered
tool is used in any forest covered, brush covered, or
grass covered unimproved land. (MA4)

■ GEAR CASE
• The reduction gears are lubricated by multipurpose,

lithium-based grease in the gear case. At every 25
hours of use, supply the gear case with new grease.
(MA5)

• Remove the cutter holders before installing new

grease to arrange for old grease to exit. (MA7)

• When removing and installing the holder(A), use

care not to allow any dirt and dust entering in to the
gear case. (MA7)

■ DRIVE SHAFT (MA6)
• The drive shaft is lubricated by multipurpose lithium-

based grease (NLGI No.2). Pull out the shaft from
the pipe and supply new grease every 50 hours of
use or more often depending on the job condition.
