All the surface of the power transmission shaft (R) should al-
ways be properly greased.
At the time of delivery from the plant, this is greased, so evenly
grease all the surface of the power transmission shaft (R) ap-
proximately 10 mL in every 18 hours.
The major points necessary for disassembling and reassem-
bling are as follows: - As pushing in the lock pin of the engine
fully, draw out the flexible shaft assembly from the engine. -
Unfasten the coupling of the flexible shaft assembly at the grip
end, draw out the flexible shaft assembly from the rear handle
assembly. - Then the power transmission shaft (R) with the
spacer can easily draw out from the flexible shaft assembly. -
Use the same grease as the angle transmission's. - When re-
assemble, it is preferable to fit the power transmission shaft
(R) reversely, but the spacer is fitted on the rear handle as-
sembly side of the powertransmission shaft (R) at all times.
Remove plug from angle transmission.
Add grease, if necessary, using low pressure pump.
NOTE
Use good quality lithium multi grease.
Do not overfill housing.
Reinstall plug.
Use only blade designated for this model by the manufacturer.
When a crack is noticed on the blade, do not use it but replace
with a new one.
Ensure that the blade is correctly fitted in accordance with the
instructions.
When the cutting blade becomes dull due to wear reverse it for
further use.
When chip or bend occurs on the blade, vibration will increase.
Replace with new one.
When filing the blade file 3 cutting edges evenly using a flat file
as shown in the illustration.
Otherwise, the balance will be lost and vibration will increase.
