CAUTION
!
If the motor unit is adjusted with the laser, the
gripping device must be attached to the pipe with
normal tension. This ensures that the saw fastening
corresponds to the normal condition of operation.
If you are not satisfied with the cutting result of your
saw and you need to adjust it again then always start
by adjusting the eccentric adjustment wheel.
Installing and changing the saw blade
WARNING
: To reduce the risk of injury, turn the
unit off and disconnect it from the power source before
installing and removing accessories, before adjusting
or when making repairs. An accidental start-up can
cause injury.
Remove the power plug from the socket.
Remove the blade guard cover (Fig N / 1) by opening
the blade guard screw (Fig N / 2). Press the spindle-
lock button (Fig A / 12) 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 nut. Remove the securing nut (Fig N /
3), the outer blade flange (Fig N / 4) and the blade
(Fig N / 5).
Before installing a new blade, check that both blade
flanges are clean. Place a new or sharpened blade on
the back flange (Fig N / 6), 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 cover.
Ensure that the new blade goes right to the bottom on
the back blade flange. Put the outer blade flange, and
the securing bolt back in place. Press the spindle lock
button and tighten the blade securing nut. Put the blade
guard cover back in place and tighten the blade cover
bolt.
When changing to Cut+Bevel Diamond disc, change
also the lower blade cover to version with wide opening
according to instructions on page 12.
WARNING
: Regular lower blade cover
must
be
installed if saw is used with regular saw blade with
cutting teeth.

Maintenance and servicing instructions
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 by an approved
service center or engineer.
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
and gearbox. When you notice that the blade is blunt
do not continue cutting 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. Diamond X Discs cannot be sharpened
Gripper unit
Clean the gripper unit regularly with compressed air.
Lubricate the gripper's wheel axles (Fig O / 1 and 3)
and its joints (Fig O / 2). Clean and lubricate also the
gripper's trapezoidal screw and the two adjusting nuts
on it (Fig O / 4).
Blade guard
When you have cut plastic pipes and then intend to
start cutting metal pipes always clean the inside of the
blade guards. Hot metal particles originating from metal
cutting will heat up 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 obstructed.
Lubricate the axis of the moving blade guard regularly.
As an extra equipment you can buy outer blade
guard with connection for vacuum cleaner. For
extra equipment see page 19.
Motor
Keep motor air vents clean to allow free airflow.
