Overload Protection And Rotation Speed Control; Improving Possible Misalignment Of The Cut; Model 280E Cutting Result Adjustment - eXact PipeCut 410E Betriebsanweisungen

Operation
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/17). 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.

Improving possible misalignment of the cut

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 saw
may move to left or right cusing unperfect cut
(see Fig M). Cutting result can be improved as
following with models 280E and 410E.

Model 280E cutting result adjustment

The model 280E gripper unit has 8 guidance
wheels. One of those is called adjustment wheel
(Fig A/9). Note that the adjustment of this wheel
applies only to the actual pipe size and material,
and the wheel may have to be readjusted as the
blade is worn.
