4.2. Saw blade guidance and saw blade co er
The saw blade guidance is mounted to the saw blade
cover. The saw blade cover should be adjusted in
such a way that the lower edge is somewhat above
the pipe to be cut.
• Keep hold of the saw blade guiding, detach the
hexagon socket screw and shift the saw blade
guiding to the requested height.
• Fix the saw blade cover by the hexagon socket
screw again.
(Saw blade guidance upper side)
The saw blade runs through the identical saw blade guidings upside and downside.
It is lead through the two rollers and supported to the backside by the larger roller on one side.
The roller with eccentric can be adjusted. It is adjusted correctly if both rollers can still be
turned somewhat towards each other and if the saw blade runs even.
For setting the guidance, release the left hand counter nut by means of fork wrench size 24.
Now the eccentric is turned with hexagon socket wrench size 6 until the rollers have the
desired distance.
Secure the eccentric again by means of the counter nut

4.3. How to adjust the sawing radius
• In order to adjust the radius, release
both clamping levers.
• Push the swiveling bow until the desired
radius is shown on the measuring tape.
• Fix the setting with the both clamping
lever.
4.3.1. How to adjust the angle for branch pipe 45° and 60°
In case of branch pipes with angle 45° or 60° having to be cut, the prism thus has to be
swiveled upwards.
For this purpose detach the two hexagon
head screws „1“ in the rear from prism and
support and unscrew the two hexagon head
screws „2“ in front.
Swivel the prism upwards and mount the
long fixings for angle 45° branch, the short
fixings for angle 60° between prism and
support and fix the hexagon head screws„2“
again.
Depending on the pipe size and angle it will
be necessary to shift the prism in order to
minimize the unsupported pipe overhang.
• For this purpose detach the hexagon
head screw „3“ and push the support with
the prism to the required position.

4.4. Vacuum (option)
It is indispensable to exhaust the cutting chips. The guidings for the swiveling arm as well as
the saw blade guiding may become sluggish resp. get damaged by the cutting chips.
Example for a vacuum:
F.e. shift the vacuum hose from one of the vacuums (option) below the guard plate just in front
of the saw blade.
Necessarily secure the vacuum against shifting f.e. by vibration during the
cutting.
Always activate the vacuum during the cutting.

5. Starting and operating
The instructions of this chapter are supposed to initiate in the operation of the machine and
lead during the appropriate starting of the machine.
This includes:
• the safe operation of the machine
• economic operation of the machine.
5.1. Starting
To start the operation, the radius band saw has to be adjusted by means of the leveling
screws in the machine feet in such a way that the swiveling bow is horizontal and the saw arm
is vertical.
• Connect the mains plug to the local power supply 400 V / 16 A / 50 Hz.
It is necessary to connect a vacuum plant (chapter: 4.4).
In situations of danger for man and machine immediately let loose the button
resp. pull the power plug!
Only cut tightly clamped pipes!
• Take care that no unauthorized person has access to the band saw.
• Protect the band saw from wetness and humidity!
The housing of the saw blade has to be cleaned regularly. For that purpose
switch off the saw.
Don’t saw without safety glasses and ear protection!
Replace the screw plug by the enclosed venting screw
before starting the band saw.
Do not throw away the screw plug, you need it again
when transporting the band saw.

5.2. How to clamp the pipes
If the swiveling retainer is not at the left limit stop,
thus swivel it there.
Lay the pipe onto the prism and clamp it by the
clamping belt in near to saw cut.
Lay the clamping belt around the pipe and the
prism.
Lead the belt from the inside to the outside
through the aperture of the ratchet and tighten it.
Clamp the pipe firmly onto the prism by moving
several times the grip of the ratchet into direction
of the arrow.
The ratchet snaps in at both ends.
Attention! Do not deform pipes with thin walls.
The belt can be unclamped again by pulling the
safety gripper into direction of the ratchet grip.
