Piercing the pipe wall
Grip the gripper firmly with your right hand and place
your left foot on top of the pipe approximately 50 cm
from the pipe saw. Turn the saw until it leans slightly
forward (Figure F). When starting the motor, first of all
release the power-switch locking lever (Fig D/1) and
push the power switch all the way down (Fig D/2).
Before starting to saw, wait until the blade reaches full
speed. Pierce the pipe wall by pressing pipe saw
operating handle downwards slowly and evenly until
the blade has cut through the pipe wall (at this stage
the pipe must not rotate) and the motor unit is locked in
the sawing position (Fig F / 1).
Look at the UNLOCK SWITCH during the piercing
operation. When UNLOCK SWITCH is locked, i.e. the
yellow mark disappears (Fig E / 1-2), the pipe saw is
locked in the sawing position, and you can safely start
sawing around the pipe.
Cutting around the pipe
Start cutting by feeding the pipe saw forward and fix
the pipe with your left foot (Fig F / 2). After that release
the pipe (remove your left foot from the pipe) and turn
the pipe saw backwards, whereby the pipe will also be
rotated backwards (Fig G). Start a new feeding
movement, and feed continuously forward ca. 1/6 of
the pipe's circumference (Fig H). Repeat until the pipe
is cut off. Select the feeding 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 cutting result.
When the pipe is cut off, push the UNLOCK SWITCH
forward until the yellow mark is visible and the locking
is released (Fig I / 1). Now raise the motor unit to
starting position (Fig I / 2). Release the power switch
(Fig I / 3). When the blade has stopped, open the
gripper safety mechanism (Fig I / 4) and disengage the
pipe saw from the pipe by loosening the gripper
adjustment handle (Fig I / 5). Ensure that the moving
lower blade-guard is lowered into safety position.
Should there be problems during piercing or cutting,
abnormal sounds or vibrations and you have to
interrupt cutting before the pipe is cut through, release
the motor unit locking by pushing the UNLOCK
SWITCH forward until the UNLOCK SWITCH 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 the position or teeth of the blade contact the
pipe to be sawn. Ensure, that the blade/disc is not
connected to pipe during the motor operating.
