BLADE CARE AND SERVICE
For best results cutter blades must be kept sharp.
The blades can be sharpened with a few strokes of a
file or grinding wheel.
DO NOT attempt to sharpen while on the rough
cutter.
Important: Replace blades that have been damaged
or deeply nicked.
Important: Check blade and spindle hardware on a
regular basis to make sure nuts are tight.
Blade installation:
To install a blade, put in place the blade (item 1) with
a bolt 3/4 x 2-1/4 grade 8 (item 2) making sure to
place the shim (item 3) between the blade and the
stump jumper (item 4). Put some extra strong locktite
on the threads of the stump jumper. Tighten the bolt
(item 2) by hand until the blade can not move freely.
Then loosen 1/8 turn. Firmly hold in place the position
of the bolt and the stump jumper. Secure the
assembly by putting some extra strong locktite on the
bolt and inserting the nylon insert lock nut 3/4’, (item
5). Torque according to the torque specification table.
If the bolt and the stump jumper are not held in place
before tightening; there is a risk that the bolt will
tighten up and will lock the blade rotation.
After installation the blade must rotate freely. If not
this will cause vibrations that can cause damages or
even injuries.
Before using the equipment again, follow the
necessary waiting period according to the locktite
manufacturer’s instructions.
NOTE: You must use a new nylon insert lock nut
every time you change a blade and a new bolt if the
old one is damaged.

HANDS.

RESULT IN SERIOUS INJURY.
