Overload Protection And Rotation Speed Control; Straightness Of Cut And Adjusting Wheel - eXact PipeCut 280E System Operating Instructions Manual

Information
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 has stopped, open the gripper safety
mechanism (Fig L/4) and disengage the pipe
saw from the pipe by loosening the gripper
adjustment handle. (Fig L/5). 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 protector and rotation speed
control
The saw has a two-speed rotation speed control
(Fig A/16). When sawing stainless or acid-proof
steel use the lower rotation speed l. When
sawing other materials use the faster rotation
speed ll. The saw also has an overload protector
which switches the power off automatically in
an overload situation. The motor part has a red
indicator light (Fig A/5), which fl ashes alerting
you to the overload and is lit continually when
the overload protector has been triggered. If the
light begins to fl ash, the motor must be cooled
down. Stop sawing and allow the motor to cool
down. You can speed up the cooling process by
running the motor without loading it. When the
motor has cooled down suffi ciently, the light will
stop fl ashing or turns off and you can continue
sawing.

Straightness of cut and adjusting 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/8) 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.
