Assembly
WARNING! Always disconnect the machine
!
from the air hoses before cleaning, assembly
and maintenance.
Fitting the cutting blade
Husqvarna's blades are approved for hand-held power
cutters. Blades are manufactured with three different
diameters of centre holes: 20 mm (0.787"), 22.2 mm (7/8")
and 25.4 mm (1"). Bushings can be fitted on the machine axle
to adjust the machine to the centre hole of the blade. Use a
bushing with the correct diameter! The blades are marked
with the diameter of the centre hole.
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.
Tightening torque for the bolt holding the blade is: 15-25 Nm
(130-215 in.lb).
The axle can be locked by inserting a screwdriver or the like
in the hole in the belt guard.
When a diamond blade is mounted on the power cutter make
sure that the diamond blade will rotate in the direction
indicated by the arrow on the blade.
When the blade is replaced with a new one, check the flange
washers and the drive axle. See instructions under the
heading Checking the drive axle and flange washers.
ASSEMBLY
Checking the drive axle and flange
washers
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.
Cutting arm
It is possible to turn the cutting arm 180° so that the blade
comes on the other side of the cutting arm. This simplifies
cutting close to obstacles such as walls and floors etc. The
cutting arm and drive belt are released in the same way as
when replacing the drive belt. See instructions under the
heading Replacing the drive belt.
Loosen the guard's stop screw and water hose.
Turn the arm 180°, replace the respective parts, and screw
them secure in the same way as before.
If you are using a diamond blade you must also turn it so that
it rotates in the right direction. A diamond blade must rotate in
the direction shown by the arrow marking on the blade.
Guard for the blade
The guard must always be fitted on the machine.
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.
