Maintenance and care
Method to change shield
There are two types of shields: namely the one used exclusively
for nylon line cutting head and the other one used exclusively for
metal blade. When metal blade is used, use the shield for metal
blade.
Fully loosen the bolt on the right side of the bracket to slide the
shield. The bolt itself cannot be removed from the bracket. Push-
ing the button, slide the shield to the left and remove it. Put shield
of other type into groove and slide it to the right until it stops. Be
sure to tighten the bolt.
Installing blade
Inspect blades before installation. Check for sharpness.
Dull blades increase the risk of blade kickback reactions.
Small cracks can develop into fractures resulting in a piece of
blade flying off during operation.
Discard cracked blades no matter how small the crack.
Blade retainer, blade, lower blade retainer, cup and nut finger
tight.
If worn nut and cup for blade are used, there is a danger of
blade getting loose. Replace them with new one.
Do not attempt to fit the trimmer blade with one hand or
without using the socket spanner. Fit the trimmer blade
accurately using the supplied socket spanner and tight-
en firmly in position.
The trimmer must not be used if the blade vibrates or is
loose.
Wear heavy duty gloves when working with the trimmer
blade. When replacing the trimmer blade during a trim-
ming task, ensure that the engine is switched off and
that the blades have stopped.
Do not use any tools other than the proved socket span-
ner 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.
When turning the product over to replace the trimmer
blade, ensure that the fuel tank cap is securely in place.
Failure to do so could lead to an injury or serious accident,
or cause a fire.
