Maintenance and care
1. Blade
1. Socket wrench
Checking the nylon line cutting head
2. Locking tool
2. Blade
Insert locking tool into a hole located on the right side of angle
transmission while forcing retainer spring to the left side. Insert
locking tool further into blade retainer fixing slot to fix output shaft.
Fasten output shaft using locking tool securely in order to
avoid the possibility of output shaft rotating when mount-
ing cutting blade which will prevent the cutting blade fas-
tening nut from being tightened sufficiently.
Tighten the nut (turn anticlockwise) using a socket wrench.
Never fasten while applying your weight. Otherwise the thread of
nut could be broken.
Replace nut and cup with new ones no matter how small the wear
is.
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 abnormal 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, re-
place 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.
