SPARK PLUG
The spark plug should be removed from the engine and checked after
each 25 hours of operation. The tips can be cleaned with a stiff brush.
Adjust the gap to 0,6-0,7mm (see sketch). Replace the spark plug if it is
oil_fouled or damaged, the average spark plug life is approximately 100
hours.
CAUTION-Do not over_tighten the spark plug. The correct torque is 10.7-
16.6N m(100 -160 kgf cm)

CYLINDER COOLING FINS
Loosen the knob (and screw : BC2259,BC2259H) and lift off the cylinder
cover. Clean all dirt and debris from the cooling fins and from around the
cylinder base. Reinstall the cylinder cover.
FUEL FILTER
The fuel filter is attached to the end of the fuel pick_up hose inside the fuel
tank. After each 25 hours of use, it should be checked for dirt or damage,
and replaced if necessary. Using a wire hook, gently pull the fuel filter out
through the fuel filler opening. Grasp the fuel hose next to the fuel filter fit-
ting and remove the filter, but do not release the hose. While still holding
on to fuel hose, attach the new fuel filter. Drop the new fuel filter back into
the fuel tank. Make sure that the fuel filter is not stuck in a corner of the
tank, and that the fuel hose is not doubled over (kinked) before refueling.
LUBRICATION : GEARCASE
The gearcase should be checked for lubrication after each 30 hours of
use. Remove the cutting attachment and the boss adapter. Clean any dirt
and debris from the area between the boss adapter and the gearcase.
Remove the grease plug from the side of the gearcase. While rotating the
attaching shaft, Inject lithium base bearing lube (P/N 211337) through the
plug hole until the gearcase is full. Reinstall the boss adapter and grease
plug.
GENERAL CLEANING AND TIGHTENING
The MARUYAMA brushcutter will provide maximum performance for many,
many hours if it is maintained properly. Good maintenance includes regular checking of all fasteners for correct
tightness, and cleaning the entire machine.
STORAGE
For long term storage of the Brushcutter, perform all regular maintenance procedures and needed repairs.
Empty the fuel tank. Start the engine and allow it to run until it stops. Pull the starter cord a few times to remove
any excess fuel from the engine. Remove the spark plug and insert a small amount of oil. Pull the starter cord
once and bring the piston to a position closest to the spark plug hole. Reinstall the spark plug. Store the brush-
cutter in a dry place away from excessive heat, sparks or open flame.
