Determination of pipe’s sawing point
Mark the sawing point on the pipe to be cut
in a way that deducts one inch from the
required measurement. The blade’s point of
contact with the wall of the pipe is one inch
from the measuring edge in the direction of
the saw’s gripper unit. Always keep in mind
that the measuring edge is set one inch
more than, or correspondingly less than,
the required measurement depending from
which direction the required dimension is
being calculated.
Attachment of pipe saw to pipe
Place the pipe saw above the pipe to be
sawn, ensuring that the gripper encloses the
pipe to be sawn. The diameter of the pipe
saw’s gripper can be adjusted with the gripper
adjustment lock (Picture A4). Place the pipe
saw at the desired position by using the
measuring edge part of the blade guard.
(Picture A 12). Adjust the gripper unit ac-
cording to the pipe’s diameter by turning the
pipe saw’s gripper adjustment lock (Picture
A4) and tightening the saw against the pipe.
Make sure that the compressed air hose or
any other object is not caught between the
gripper and the pipe to be cut. Never begin
sawing if your fingers, or any other improperly
placed clothes or other tools, are between
the gripper and the pipe. Also remove any
possible sand and/or other debris from
under the gripper. Make sure that the saw
travels freely. If the saw is not moving proper-
ly, detach the saw from the pipe and check
the gripper’s wheels and ball bearings, (Picture
A7) cleaning and oiling them if necessary. If
the saw’s gripper unit has been damaged, the
machine cannot be used until it is repaired.
Piercing and sawing of pipe wall
Make sure that all persons working near
the pipe saw have the appropriate personal
protection equipment.
Firmly grip the saw’s operating handle
(Picture D1) with your right hand and hold
the gripper adjustment lock (Picture A4)
with your left hand.
Pierce the pipe’s wall by gently pushing
the pipe saw’s operating handle directly
downwards with an even pressure until
the blade has cut through the pipe’s wall
and the motor unit has locked in the
sawing position. You will feel the locking
when the locking pin (Picture A3) snaps
into the slot designed for it (Picture A6)
and moves slightly to the right.
Now that the pipe saw is locked in the
sawing position and you can safely begin
the pipe’s circular sawing. Never feed the
saw in the wrong direction.
Filling of oil tank
When the oil tank’s piston is visible in the
oil level sight glass, and the motor is not
running other than by pressing the Start
button, oil should be added to the oil tank.
The piston must always be pressed down-
wards when oil is being added.
Make sure that the pressure has been dis-
connected from the saw and that the intake
hose is detached. Unscrew the oil tank’s
cap. Use a clean tool such as a screwdriver
to press the oil tank’s piston into the down-
ward position. This pressing is done through
the hole in the oil cap. While pressing, make
sure that the threading inside the hole
remains undamaged. After pressing, the
piston will no longer be visible in the oil level
sight glass. The best way to fill the oil tank
is with a hypodermic syringe. The volume
of the tank is approximately 0.05 liters, or
about 3 cubic inches. After the filling, screw
the oil tank cap back in place. Any possible
oil spillage should be carefully wiped away.
NOTE! The level of the oil, for example at
the halfway mark, may be visible in the
tank’s oil level sight glass. This does not,
however, indicate the actual level of the oil.
The position of the piston, also visible in the
oil level sight glass, provides the only true
indication of the amount of oil in the tank.
When the piston has been pushed down it is
no longer visible in the oil level sight glass.

Release the motor unit to the upper posi-
tion by pulling the locking pin (Picture A3)
and press the STOP (Picture A2) button
immediately to turn off the motor. Always
avoid using the motor without loading.
Operational instructions
Operational instructions
The feeding speed is selected according to
the pipe’s material and wall thickness. An
excessive feeding speed can damage the
blade, overload the pipe saw, and cause
a poor sawing result. Control the feeding
speed during the entire duration of the
cutting. Never completely let go of the saw
while cutting.
The pipe’s circumferential sawing
consists of four steps:
1. Begin the sawing by feeding the pipe
saw forward while gripping the handles
(Picture D1 and D2) until you have
sawed approximately one-fourth of
the pipe’s circumference.
2. Change your grip on the handles:
(Picture D4 and D5) now the pipe saw’s
own weight helps the feeding motion
and you can also slightly brake the
feeding speed.
3. When the pipe saw is under the pipe,
change the position of your grip on the
handles (Picture D2 and D3) and pull
the pipe saw forward and upwards until
you have sawed approximately three-
fourths of the pipe’s circumference.
4. Once again change the position of your
grip on the handles (D1 and D6) and
feed the pipe saw until the cutting is
completed.
