Remove the power plug from the socket. Check that the
motor unit is locked in the upper position.
Remove the blade guard cover (Fig. O/1) by opening the
two finger screws (Fig. O/2). Press the spindle-lock button
(Fig. A/11) and simultaneously rotate the blade by hand
until the spindle-lock button drops a further distance of
about 7 mm. Now the rotation of the blade is prevented.
Use the blade key to open the blade attachment bolt.
Remove the securing bolt (Fig. O/3), the washer (Fig. O/4),
the blade flange disc (Fig. O/5), and the blade (Fig. O/6).
Before installing a new blade, check that both blade
flange discs are clean. Place a new or sharpened blade on
the back flange disc (Fig. O/7), so that the marked side of
the blade is facing outwards and the arrows on the blade
are facing in the same direction as the rotation direction
markings on the inside of the blade case.
Ensure that the new blade goes right to the bottom
in the back flange disc. Put the blade flange disc, the
washer, and the securing bolt back in place. Press the
spindle lock button and tighten the blade securing bolt.
Put the blade guard cover back in place and tighten the
finger bolts.
Remove the power plug from the socket before servicing
or cleaning the pipe saw. All maintenance operations
carried out on the pipe saw’s electrical components must
be carried out at an approved service agency.
Blade
Check the condition of the blade. Replace a bent, blunt,
or otherwise damaged blade with a new one. Using a
blunt blade can overload the pipe saw’s electric motor.
When you notice that the blade is blunt, do not continue
sawing with it, as the blade may become so badly
damaged that it will not be worth sharpening.
A blade in sufficiently good condition can be sharpened a
few times by a professional sharpening company.Use only
Pipecut blades.
Gripper unit
Clean the gripper unit regularly with compressed air.
Lubricate the gripper’s wheel axles (Fig. P/1) and its
joints (Fig. P/2). Also clean and lubricate the gripper’s
trapezoidal screw (Fig. P/3) and the two worm screws on
it (Fig. P/4).

Blade guard
When you have sawn plastic pipes and then intend to
start sawing metal pipes always clean the inside of the
blade guards.
Hot particles derived from sawing metal will burn plastic
particles, which may release toxic smoke. Make it a
rule to clean the blade guard regularly, and pay special
attention to keep the moving blade guard movement
from becoming hampered. Lubricate the axis of the
moving blade guard regularly.
Motor
Keep the motors cooling vents clean.
Plastic parts
Clean the plastic parts with a soft rag. Only use mild
detergents.
Do not use solvents or other strong detergents
as they may damage the plastic parts and paint
surfaces.
