Checking the blade
Maintenance and care
1.
Check plug gap. Correct gap is 0.6 mm to 0.7 mm.
2.
Inspect electrode for wear.
3.
Inspect insulator for oil or other deposits.
4.
If the spark plug is dirty, clean it. Do not sandblast to clean.
Remaining sand will damage engine.
5.
If the electrodes or terminals are worn, or if there are cracks
in the ceramics, replace them with new parts. (see Specifi-
cationspage 30)
6.
Tighten to 15 N·m - 17 N·m (150kgf·cm to 170 kgf·cm).
The spark test (for checking whether the spark plug is spark-
ing) must be carried out by your dealer.
Inspect the drive shaft (A) every 100 hours of use and replenish
grease if it is insufficient.
NOTE
Use good quality lithium multi grease.
1.
Remove the plug (A) and drain screw (B) from the angle
transmission (C).
2.
Add grease into the transmission until old grease is pushed
out. If necessary, use a low pressure pump.
Use good quality lithium multi grease.
3.
Reinstall the drain screw and 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.
