TYROLIT Hydrostress HBE 350, Operating Instructions Manual

Page: 12 / 24

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
Blade Guard Locking Lever
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.
SPLASH GUARD
The spring-loaded splash guard is useful to help to contain slurry which splashes toward the back.
To install, simply clip into place on the back of the dust port bracket. To remove, tilt upward to pop free.
If the splash guard is not needed, such as when cutting dry, it may be clipped up out of the way. Simply engage
the male clip on the flap with the female clip on the mount. Unclip to release.
WATER CONNECTION
Water is a basic requirement for diamond sawing with wet-type diamond blades. The water serves as a coolant
to avoid the working surface of the diamond segments from overheating.
When the diamond bit becomes overheated, both the bond matrix and even the diamonds break down, thus
destroying the blade. Besides cooling, water also keeps down dust and flushes away abrasive particles.
