Operation
For this reason the result may vary, and the
cut may turn to left or right (misalignment of
the cut's starting and ending point) (Fig. M).
The pipe saw gripper has one adjustable
wheel (Fig. A/9) which be used for improving
the quality of the cut and for reducing the
misalignment. The adjustment applies only to
the actual pipe size and material, and the wheel
may have to be readjusted as the blade is worn.
To adjust the wheel, loosen the locking screw
(Fig. N/1) and turn the wheel centre clockwise
or counter clockwise to the desired position
(Fig. N/2), and lock the wheel again (Fig. N/3).
If the blade has wandered too much to the
left, adjust wheel centre clockwise (- sign). If
the misalignment is to the right, adjust counter
clockwise (+ sign). The extent of the adjustment
depends on the actual misalignment. Remember
to lubricate the adjusting wheel at regular
intervals.
Installing and changing
the blade/disc
WARNING: To reduce the risk of
injury, turn unit off and disconnect it
from 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. Check
that the motor unit is locked in the upper position.
Remove the blade guard cover (Fig. O/1)
by opening the two 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 0,2". 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
fl ange disc (Fig. O/5), and the blade (Fig. O/6).
Before installing a new blade, check that both
blade fl ange discs are clean. Place a new
or sharpened blade on the back fl ange 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 fl ange disc. Put the blade
fl ange 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 bolts.
