Maintenance and care
Angle transmission
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.
3. Reinstall the drain screw and plug.
Checking the blade
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.
Checking the nylon line cutting head
1. Make sure each periphery of the 2 retaining pawls of housing
spreads almost fully up to the outer periphery of the respec-
tive cover window.
2. Check mount of cutting head on trimmer and tighten if it is
loose.
3. Check the cutter head for deflection or abnormal noise rotat-
ing it by hand. Deflection or abnormal noise can cause ab-
normal vibration to occur or mount to trimmer to loosen
during rotation which is dangerous.
4. Inspect cover and tap knob for wear. When slot appears on
bottom of the tap knob or when slot appears on cover bottom
close to outlet for nylon line, replace them with new parts
without fail.
5. Check the cutting head for crack or chip. Replace parts that
show any crack or chip with new ones without fail.
NOTE
Use good quality lithium multi grease.
