manipulate the vacuum hose. When rocks or chunks of
stone/masonry are drawn into the vacuum hose, cease
work and clean the vacuum hose immediately. Prevent
the vacuum hose from being bent or creased.
• Use the wall saw machine only as intended for.
• Observe the general requirements for construction sites.
• Provide for good ventilation.
• Ensure that the work area is free of obstructions. For
longer grinding jobs, the vacuum cleaner must be able to
move along freely and at the right time.
• Wear hearing protection, protective goggles, a dust mask
and gloves as required. As dust mask, use at least a
particle-filtering class FFP 2 half-mask.
• Use a suitable vacuum cleaner for cleaning the work-
place. Prevent settled dust from being swirled up by
sweeping.
ASSEMBLY INSTRUCTIONS
Necessary tools:
• Wrench 6 mm.
• Screwdriver or pin.
To install the diamond cutting blade follow next steps (see
page 4, image A):
• Disconnect from the power supply.
• Loosen the depth locking leaver (#10).
• Remove the flange cover from the blade guard.
• Move the motor until the flange with bolt appears before
the hole.
• Loosen the bolt with the delivered wrench and remove
the flange. It is possible that the bolt is stuck. In that case:
use a pin or screwdriver between the diamond cutting
blade's teeth to block the axle, and loosen the bolt.
• Check the condition of the flange set. The surfaces
between the flange and the diamond cutting blade need
to be clean and must fit exactly.
• Mount the new diamond cutting blade. Please pay
attention to the direction of rotation. The direction on
the diamond cutting blade has to be identical to the
machine's rotation direction.
• Mount the flange on the axle.
• Screw the bolt in the axle.
• Prevent the diamond cutting blade from turning by
blocking it with a screwdriver or pin between the teeth of
the diamond cutting blade and tighten the bolt.
Use the same procedure to change a worn diamond
cutting blade.
OPERATION INSTRUCTIONS
Before cutting in a wall, floor or similar object: investigate
14
whether the object contains any electric, water or gas
conduits. If necessary, use a locator for detecting conduits
in the object.
Only use diamond cutting blades.
It is strictly forbidden to use other blades, like circular
woods blades, because the extra necessary protection fails.
Do not use deformed, damaged or bad diamond cutting
blade.
The voltage of the wall socket must be similar to the
voltage indicated on the machine.
To prevent unintentional starts, the wall saw machine is
provided with a lock-off button (#12).
For further use of the machine please check the safe-
guards for proper functioning. In case of damage to the
case or other parts, these need to be repaired or repla- ced
by a professional service department. Don't use other
equipment that cannot be flawlessly switched ON and OFF.
While using, please hold the machine with both hands
Starting the machine:
• Connect to the power supply.
• Press the lock-off button (#12).
• Press the main ON/OFF switch (#13).
• Release the switch (#13 ) to turn the machine OFF.
Adjust the cutting depth.
The depth of the cut needs to be adapted to
of the hardness of the material to be cut.
Using the machine as followed will prevent
any overload.
Cutting in concrete has to be done in steps of 2,5 to 5 cm
of depth; so for instance: a depth of 12 cm depth can be
reached in 2 or 3 steps. Cut brick in steps of 5 to 8 cm,
depending on the hardness of the stone.
Adjust the cutting depth:
• Disconnect from the power supply.
• Loosen the depth locking leaver (#10).
• Adjust the saw depth by moving the motor along the rails.
• Lock the depth locking leaver (#10).
Use the right diamond cutting blade.
Choose a type of diamond cutting blade which is suitable
for the material to be sawn. We advice CARAT diamond
cutting blades. Please read all the instructions of the dia-
mond cutting blades.
Make sure that the diamond cutting blade is turning in the
right direction. Check the arrow on the blade guard for the
correct direction.
