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

COOLING FINS CLEANING
1. Loosen the knob (and screw: BC3021H)and lift off the cylinder cover.
2. Clean all dirt and debris from the cooling fins and from around the
cylinder base.
3. 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 fitting 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 brushcutter in a dry place away from excessive heat, sparks or open flame.
