INSTRUCTIONS FOR USE
Select the sawing speed as per the material and the
thickness of the wall. Too high speed can damage the
blade, overload the pipe saw and give a poor sawing
result.
When the pipe is cut off, push the UNLOCK button
forward until the yellow mark is visible and the locking is
released (Fig L/1). Now raise the motor unit to starting
position (Fig L/2). Release the power switch (Fig L/3).
When the blade is stationary, remove the pipe saw from
the pipe by loosening the gripped handle (Fig L/4). Ensure
that the moving lower blade-guard is lowered into safety
position.
Should there be problems during piercing or sawing,
abnormal sounds or vibrations due to which you have to
interrupt sawing before the pipe is cut through, release
the blade by pushing the UNLOCK button forward until
the UNLOCK button is released, and lift the motor unit
up. Once the problem is cleared, start sawing again.
Never start the motor, when the motor unit is locked in
sawing position or teeth of the blade contact the pipe to
be sawn.
Overload protection
The pipe saw is equipped with overload protection. When
the blade is dull or the speed is too high, the overload
protection cuts power automatically. Restore the power
by pushing the overload protection switch (Fig A/15).
Straightness of cut and control wheel
The cut is affected by many factors, e.g. the size of the
pipe, the material, the wall thickness, the quality of
the pipe’s surface, the roundness, welded seams, blade
condition, feed rate, operator’s experience. 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.
The wheel can be adjusted in 9 positions; mid position
and 4 steps to left and right. To adjust the wheel, loosen
the locking screw (Fig N/1) and turn the wheel center
clockwise or counterclockwise to the desired position
(Fig N/2), and lock the wheel again (Fig N/3). If the
blade has wandered too much to the right, adjust wheel
center clockwise. It the misalignment is to the left, adjust
counterclockwise.
The number of steps depend on the actual misalignment.
Remember to lubricate the adjusting wheel at regular
intervals.
