ASSEMBLY PROCEDURES
Assembly of cut-o
ff
wheel
1. Place the wheel (1) between the two
fl
anges (2), and
tighten the bolt (3) by hand. (
Fig. 6
)
2. Insert the hex. wrench (4) into the hole of arm cover (5)
and lock the spindle in place while tightening the bolt (3)
securely using the combi box spanner (6). (
Fig. 7
)
3. Make sure the rotation direction of the diamond wheel
conforms to the direction indicated on the clutch cover
and install the diamond wheel. (
Fig. 8
)
NOTE
○
When using a wheel with an arbor hole of 25.4mm, securely
attach the adapter collar (7) to the spindle. (
Fig. 9
)
○

WARNING
○
Do not use damaged wheels. Before each use, inspect
the wheels for chips, cracks, distortion of shape or
imbalance and reject any such wheel.
○
When you use the abrasive cut-o
ff
wheel check the
expiration year marked (8) on the wheel before attaching.
(
Fig. 10
)
There is a risk of bursting when using a wheel that it past
its expiration year.
○
Before tightening the bolt, check that the direction of the
two
fl
anges is correct. Also check that the
fl
anges are
securely installed in the
fl
ats of the spindle.
○
The correct tightening torque is 20 N·m. Do not tighten
more than 20 N·m.
○
Check the wheel by running it for 1 minutes at full throttle
before applying it to a workpiece.
