Installing Brushcutter Blade
WARNING!
Do not attach any blade to
a unit without proper installation of
all required parts. Failure to use the
proper parts can cause the blade to
and/or bystanders.
1. Turn the unit upside down so the gear
case output shaft is facing UP and
remove the shaft bolt, bolt guard and
holder B from the gear case shaft.
2. Align the hole in blade holder A with
the matching hole in the gear case
flange and then temporarily lock the
output shaft by inserting a hex wrench
through both holes.
3. Fit the blade over the flange on holder A.
WARNING!
hole must be centered over the raised
boss on blade Holder A.
CAUTION!
Install the blade so its printed surface
is visible to the operator when the
brushcutter is in the normal operating
position.
IMPORTANT!
Discard blades that are bent, warped,
cracked, broken or damaged in any way.
Use a sharp blade. A dull blade is more
likely to snag and thrust.
