WARNING:
when handling or performing maintenance on
the blade to avoid injury. The blade is sharp and
can cut you even when it is not moving.

Do not use any blades, or
fastening hardware other than the washers and
nuts shown in the following illustrations. These
parts must be provided by Jonsered, and
installed as shown below. Failure to use proper
parts can cause the blade to fly off and seriously
hurt you or others.
1. Install the dust cup over the threaded
shaft.
2. Install the blade and the retaining washer
over the threaded shaft of the gearbox.
3. Make sure the raised part of the retaining
washer is facing the gearbox and the
raised area fits into the hole in the center

the dust cup and the retaining washer. There
should be no space between the blade and the
dust cup or the retaining washer.
6. Align hole in dust cup with hole in side of
gearbox by rotating the blade.
7. Insert a small screwdriver or hex wrench
(provided) into aligned holes. This will
keep the shaft from turning while tighten-
ing the blade nut.
