MAINTENANCE
Air filter (see Fig. 14)
•
The air filter should be cleaned daily, or more often when
working in extremely dusty conditions.
•
Replace every 100 hours of operation.
1.
Remove the foam element (A).
2.
Clean the foam element with warm, soapy water.
Let the element dry completely.
3.
Apply a light coat of SAE 30 motor oil to the foam element
and squeeze out all excess oil.
4.
Put the foam element and filter cover back in place.
Fuel filter (see Fig. 15)
The fuel filter should be replaced every 100 hours of operation.
1.
Make sure the fuel tank is empty.
2.
Unscrew the fuel tank cap, and pull up and remove the cap
holder (A).
3.
Using a wire hook, gently pull the fuel filter out through
the fuel filler opening.
4.
Grasp the fuel hose next to the fuel filter fitting and remove
the filter (B), but do not release the hose.
5.
While still holding on to the fuel hose, attach the new fuel filter.
6.
Drop the new fuel filter back into the fuel tank.
7.
Make sure that the new fuel filter is not stuck in a corner
of the tank, and that the fuel hose is not doubled over
(kinked) before refuelling.
Spark plug (see Fig. 16)
•
The spark plug should be removed from the engine
and checked every 25 hours of operation.
•
Replace the spark plug every 100 hours of operation.
1.
Gently twist the high tension lead boot on the spark plug
back and forth a couple of times to loosen the boot,
then pull the boot off the spark plug.
2. Remove the spark plug.
3.
Clean the electrodes with a stiff brush.
4.
Adjust the spark plug gap to 0.6-0.7 mm.
5.
Replace the spark plug if it is oil-fouled, damaged,
or if the electrodes are worn down.
6.
Do not overtighten the spark plug when installing.
The tightening torque is 12-15 Nm.
Cylinder cooling fins (see Fig. 17)
•
The cylinder cooling fins should be cleaned every 25 hours
of operation, or once a week, whichever comes first.
•
Air must flow freely around and through the cylinder cooling
fins to prevent engine overheating. Leaves, grass, dirt
and debris build-up on the fins will increase the operating
temperature of the engine, which can reduce engine
performance and shorten engine life.
1.
Loosen the clamping mechanism and lift off the cylinder
cover.
2.
Clean all dirt and debris from the cooling fins and from
around the cylinder base.
3.
Put the cylinder cover back in place.
Gearcase lubrication (see Fig. 18)
•
The gearcase should be checked for lubrication every
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
(A: P/N 211337) through the plug hole (B) until the
gearcase is full. Put the boss adapter and grease plug
back in place.
Daily inspection
•
Make sure that the cutting attachment is not cracked
or damaged. Replace it if damaged.
•
Make sure there are no fuel leaks from the engine.
Repair as required, should any leaks appear.
•
Check all fasteners on the unit. If loose, tighten them
properly.
Storage (see Fig. 19)
For long-term storage of the trimmer/brushcutter:
1.
Empty the fuel tank into a suitable fuel storage container.
2.
Pump the primer bulb on the carburetor until all fuel
is discharged through the clear fuel return hose.
3.
Run the engine to remove any fuel that may remain
in the carburetor.
4.
Carry out all regular maintenance procedures and any
needed repairs.
5.
Remove the spark plug and squirt a very small amount
of engine oil into the cylinder.
6.
Pull the starter grip once.
7.
Slowly pull the starter grip to bring the piston to the top
of the cylinder (TDC).
8.
Put the spark plug back in place.
9.
Store the trimmer/brushcutter in a dry place away from
excessive heat, sparks or open flame.
