Before you start
Installation of shield
Fit shield to mounting portion of angle transmission and tighten 4
bolts.
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 using nylon line cutting head, use the shield
for nylon line cutting head.
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.
