ASSEMBLING AND ADJUSTMENTS

Fitting the cutting blade

• The blade is placed on the bushing (C) between the
inner flange washer (A) and the flange washer (B).
The flange washer is turned so that it fits on the axle.
• The cutting blade/axle can be locked by holding in the
locking button on the rear of the machine. The button
is spring-loaded and is reset when button is released.
• 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.
