Method to change shield
Installing blade (option)
 Wear heavy duty gloves when working with the trimmer blade.
 When replacing the trimmer blade during a trimming task, ensure that the engine is switched off and that the blades
have stopped.
 When turning the product over to replace the trimmer blade, ensure that the fuel tank cap is securely in place.
 Do not attempt to fit the trimmer blade with one hand or without using the socket spanner. Fit the trimmer blade ac-
curately using the supplied socket spanner and tighten firmly in position.
 Do not use any tools other than the provided socket spanner to tighten the blade; a pneumatic or electric tool may
tighten the blade more than necessary and cause the nut or the output shaft to break.
 If worn nut and cup for blade are used, there is a danger of blade getting loose. Replace them with new one.
Failure to do so could lead to an injury or serious accident, or cause a fire.
Inspect the drive shaft (A) every 100 hours of use and replenish
grease if it is insufficient.
 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.
 There are two types of shields: namely the one used exclu-
sively for nylon line cutting head and the other one used exclu-
sively for metal blade. When metal blade is used, use the
shield for metal blade.
1. Fully loosen the bolt (A) on the right side of the bracket (B)
to slide the shield. The bolt itself cannot be removed from the
bracket.
2. Pushing the button (C), slide the shield (D) to the left and re-
move it.
3. Put shield of other type (E) into groove and slide it to the right
until it stops. Be sure to tighten the bolt.
