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

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.
