Checking the drive shaft and flange
washers
When the blade is replaced with a new one, check the flange
washers and the drive shaft.
• Check that the threads on the drive shaft are undamaged.
• Check that the contact surfaces on the blade and the
flange washers are undamaged, of the correct dimension,
clean, and that they run properly on the drive axle.
Do not use warped, notched, indented or dirty flange
washers. Do not use different dimensions of flange washers.

Checking the bushing

Bushings are used to fit the machine to the centre hole in the
cutting blade. The machine is supplied with two different sized
bushings, 20 mm (25/32'') and 25, 4 mm (1''). A plate on the
blade guard indicates which bushing has been factory-fitted.
When replacing the bushing, the labeling of the machine must
be updated with the supplied decal.
• Check that the bushing on the machine's spindle shaft
corresponds with the centre hole of the cutting blade. The
blades are marked with the diameter of the centre hole.
Checking the direction of the blade
rotation
• When using diamond blades make sure that it rotates in
the direction indicated by the arrow on the blade. The
direction of rotation for the machine is shown by arrows on
the cutting arm.

Fitting the cutting blade

• The blade is placed on the bushing (A) between the inner
flange washer (B) and the flange washer (C). The flange
washer is turned so that it fits on the axle.
• Lock the shaft. Insert a tool in the hole in the cutting head
and rotate the blade until it is locked.
• Tightening torque for the bolt holding the blade is: 15-25
Nm (130-215 in.lb).

Blade guard

The guard for the cutting equipment should be adjusted so
that the rear section is flush with the work piece. Spatter and
sparks from the material being cut are then collected up by
the guard and led away from the user.
The blade guard is friction locked.
• Press the ends of the guard against the work piece or
adjust the guard with the adjustment handle. The guard
must always be fitted on the machine.
