Installation of bracket
Fit bracket to mounting portion of angle transmission and fix the
bracket by holding fitting plate pressed from beneath and tighten
4 bolts (M5×25) lightly.
Get notches and convexes of fitting plate to face corresponding
convexes and concaves of bracket, and fix bracket tightening 4
bolts (M5×25) securely.
Method to change shield
Remove bolt (M5×18) on the right side of the shield and slide the
shield to the left and remove it. Put shield of another type into
groove and slide it to the right until it stops and be sure to fasten
with the removed bolt (M5×18).
When using nylon line cutting head, use the shield for nylon line
cutting head (see Page 18 in the section "Loop handle version
18").
Fit cut off knife to the shield for nylon line cutting head using
screw (5×12).
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.
