Operation
Attaching the pipe saw to the pipe
Open the pipe saw's gripper unit enough to suit the
diameter of the pipe by rotating the adjustment
handle located at the rear of the saw (Fig. E/1).
Position the pipe saw on top of the pipe so that the
edge of the lower blade guard is at the cutting mark.
Fasten the pipe saw to the pipe by turning the gripper
adjustment handle until the gripper grips firmly the
pipe to be cut (Figure E/2). Hold the pipe in place
and ensure that pipe saw moves freely in the direction
the pipe is fed. For sake of safety ensure the pipe
saw leads are to the left of the pipe saw. The pipe
saw is now ready for cutting.
Piercing the pipe wall
Grip the gripper firmly with your right hand and place
your left foot on top of the pipe approximately 20"
from the pipe saw. Turn the saw until it leans slightly
forward (Figure H). When starting the motor, first
of all release the power-switch locking lever (Fig
F/1) and push the power switch all the way down
(Fig F/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 H/1).. Look
at the UNLOCK button during the piercing operation.
When UNLOCK button is locked, i.e. the yellow
mark disappears (Fig G), pipe saw is locked in the
sawing position, and you can safely start sawing
around the pipe.
Sawing around the pipe
Start sawing by feeding the pipe saw forward and
fix the pipe with your left foot (Fig H/3).. 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 J). Start a new
feeding movement, and feed continuously forward
ca. 1/6 of the pipe's circumference. Repeat until the
pipe is cut off (Fig K).
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
sawing result.
