Hilti DSH 700 Mode D'emploi page 17

CAUTION
Don't use synthetic resin-bonded fiber-reinforced
cutting discs that have exceeded their use-by date.
CAUTION
Don't use damaged diamond cutting discs (cracks in
en
the steel disc, broken or polished segments, damaged
arbor hole, bent or distorted steel disc, heavy discol-
oration due to overheating, steel disc worn away
beneath the segments, diamond segments with no
lateral overhang, etc.)
1. Insert the locking pin in the hole in the drive belt
cover and turn the cutting disc until the locking pin
engages.
2. Use the wrench to release the clamping screw by
turning it counterclockwise.
3. Remove the clamping flange and the cutting disc.
4. Check that the mounting bore of the cutting disc to
be fitted corresponds with the centering collar of the
cutting disc mounting flange. The mounting flange
is provided with a 20 mm diameter centering collar
on one side and a 25.4 mm (1") diameter centering
collar on the opposite side.
5. Clean the clamping and centering surfaces on the
machine and on the cutting disc.
6. CAUTION Take care to ensure that the direction
of rotation of the cutting disc (indicated by an ar-
row) matches the direction of rotation shown on the
machine.
Place the cutting disc on the centering collar of the
clamping flange.
7. Place the clamping flange on the drive arbor and
tighten the cutting disc clamping screw by turning it
clockwise.
8. Insert the locking pin in the hole in the drive belt
cover and turn the cutting disc until the locking pin
engages.
9. Tighten the cutting disc clamping screw to a torque
of 25 Nm.
6.3 Adjusting the guard
DANGER
Don't operate the machine without the protective
devices that belong to it.
DANGER
Adjust the guard to the correct position. Direct the
particles of material removed away from the operator
and the machine.
WARNING
The motor and the cutting disc must have come to a
complete stop before making adjustments or chang-
ing parts etc.
10
Hold the guard by the grip provided and rotate it to the
desired position.
6.4 Converting the saw from normal cutting mode
to flush cutting mode 4
DANGER
Adjust the guard to the correct position. Direct the
particles of material removed away from the operator
and the machine.
NOTE
After completion of flush cutting it is recommended that
the saw is converted back to normal cutting mode due to
the more favorable balance in this position.
NOTE
After doing this, check that the cutting disc can be turned
easily by hand and that all screws have been tightened
securely.
DANGER
Don't operate the machine without the protective
devices that belong to it.
In order to facilitate cutting as closely as possible to
edges and walls etc., the forward section of the saw arm
can be turned and fitted in the reversed position so that
the cutting disc, when seen from behind, is positioned to
the right of the saw arm.
1. Remove the spray jets from the guard.
2. Slacken the three clamping nuts on the forward
section of the saw arm approx. one complete turn.
3. Release the tension on the drive belt by turning the
belt tensioning cam counterclockwise carefully as
far as it will go (until resistance is felt, i.e. approx. ¼
of a turn).
4. Remove the three clamping nuts and the two secur-
ing screws from the forward section of the saw arm,
then remove the drive belt cover and the forward
section of the saw arm.
5. Release the four securing screws on the rear drive
belt cover and remove the cover.
6. Remove the stop screw that limits rotation of the
forward section of the saw arm.
7. Place the drive belt carefully over the drive pulley.
8. Fit the forward section of the saw arm onto the rear
section of the saw arm. Fit only the middle clamping
nut. Tighten the nut only finger-tight.
9. Rotate the disc guard until the opening is at the rear.
10. Tension the drive belt by turning the belt tensioning
cam clockwise carefully as far as it will go (until
resistance is felt, i.e. approx. ¼ of a turn).
11. Secure the forward drive belt cover with the two
clamping nuts and two securing screws.
