MOUNTING THE BLADE
First make sure that the machine is unplugged.
Then, using the 17mm combination wrench, engage the arbor bolt and turn the arbor while pressing on the
arbor lock . When the arbor reaches the right position, the arbor lock will be allowed to engage. Then the arbor
bolt may be loosened and the plain outer flange may be removed.
The inner flange of this machine is 1" (25.4mm). Check the inner flange to ensure that the size matches the bore
of the blade .
Inspect the blade before use. It must not be cracked, warped or damaged in any way that would cause a hazard
in operation. Loose diamond segments can be ejected at high speed, causing possible injury. Always check
that the diamond segments are not under cut. If the diamond segments are thinner or nearly thinner than the
blade core, the kerf will be too tight fitting and could easily lead to kickback.
Ensure that the flanges and blade bore are clean and undamaged and that everything fits properly. The flanges
may not be used if they are warped, the surface is uneven, burred or if they are dirty. The arbor bolt and
arbor threads must be undamaged. Inspect the blades for segment damage, arbor hole damage or any other
damage which could cause hazardous operation.
The protruding edge of the inner flange should be facing the blade. Then mount the blade to the inner flange
and add the outer flange. Add the arbor bolt and tighten to 15-25 Nm.
WARNING: Do not attempt to mount a blade which does not match the mounting hardware. It will lead
to eccentric running and vibration which will be uncontrollable.
ADJUSTING THE BLADE GUARD
The blade rotates clockwise when viewed from the arbor end. Therefore, most of the cutting debris, sparks
and slurry is thrown to the rear. So the blade guard should be adjusted so that the rear edge is flush with the
workpiece.
TO ADJUST
First pull out the locking lever against the spring tension, then rotate the
blade guard to the desired position. Allow the locking lever to engage the
nearest slot in the guard to lock it into position.
BLADE GUARD BRUSH
There is a removable brush at the rear of the guard to help contain sparks, dust, debris and slurry. To install,
simply push the brush into the slot in the bottom of the dust port bracket until it clicks in place. This brush may
be pulled straight out to replace when worn.
