CYLINDER COOLING FINS
Loosen the knob 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 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 dou-
bled 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 re-
move any excess fuel from the engine. Remove the spark plug and insert a small amount of oil. Pull the start-
er 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.
