4.1. Elements to lock the saw arm
The saw arm features below lug 2with two drill holes. The locking bolts are stored in the lug.
The revolving plate features lug 1and 3.
In order to make straight cuts, you must not lock the saw arm.
The locking device from lug 2to lug 3is meant for the optional circular cutting.
Lock lug 2to one of the drill holes in the basic plate (chapter 4.3) in case you want to cut an
angle.
Lock lug 2to lug 1in case you want to transport the saw.
4.2. Saw blade guiding
The saw blade runs through the saw blade guidings above and below. The saw blade is
guided in each of the front rollers, and is unilaterally held to the rear by a larger roller.
The side without large roller has an eccentric bolt
and can thus adjust the band guiding.
The adjusted position is correct if both rollers in the
front can just be turned against each other and the
saw blade is smoothly running.
In order to adjust the guiding rollers detach the
counter nut of the eccentric bolt by flat wrench SW
24. Now you can turn the eccentric bolt by Allen
wrench SW 6 until the rollers do have the desired
gap. Secure this position by tightening the counter
nut.
You may also use a smaller saw blade (optional) with 10 mm width in order to cut
small radii.
For this purpose you must replace the guide rollers by the ones with large bezels
(see chapter: 6.6.1).

4.3. How to set the swiveling angle
In order to turn the saw arm, release both clamping levers and pull out the locking pins.
Now turn the saw arm onto the requested angle.
Lock the angle by the locking pins (right image).
Additionally tighten both clamping levers.
4.4. Linear laser (optional) and saw blade covering
At the upper saw blade guiding, there is the (optional)
linear laser. It indicates the cutting course on the
clamped pipe.
Adjust the light beam in a way that it is vertically
located above the saw blade.
Example: in case the saw is in position 90°, the light
beam also indicates 90° on the scale. Turn on/off the
laser via the sliding switch.
The laser is operated by a mignon battery.
In order to replace the battery, detach the upper
cover, change the battery and close the cover again.

Please take the exact setting and further details from the separately enclosed working
instructions of the laser, type: ZA3.
The saw blade covering is recommended to be adjusted in a way that the lower edge of the
cover is a bit above the pipe to be cut.
In order to displace the covering, detach the star screw and push the saw blade covering
to the desired height. Afterwards, tighten the star screw again.
4.5. Clamping pipe
4.5.1. Pipe clamping device (optional)
How to set the clamping device:
Release clamping lever 2 of the telescopic clamping arm and push the telescope in / out
(arrow) of the clamping arm; arrest the desired position with clamping lever 2.
In order to swing the clamping arm, release clamping lever 1, swing the clamping arm into
the desired position and lock it with clamping lever 1.
The pipe clamper is turning horizontally.
Upon clamping it is turned manually onto the pipe center.
The height of the clamping arm can be adjusted by means of the control slide. For that
purpose release the screw in the control slide, bring the clamping arm to the desired height
and tighten the screw again.
By turning the lever of the manual valve, the pipe clamping fixture is moved up and
downwards and the pipe is clamped.
Regulate the speed of opening and closing the pipe clamping fixture at the respective exit
air - one-way flow restrictor.
Set the desired clamping pressure at the pressure regulator.

4.5.2. How to clamp the pipes with clamping belt (optional)
Lay the pipe onto the pipe support (take care of the
saw blade distance!) and clamp it by the clamping
belt.
Lay the clamping belt around the pipe and the pipe
support. Lead the belt from the inside to the
outside through the opening of the ratchet and
tighten it (see illustration). Clamp the pipe firmly
onto the pipe support 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.
