4.1.1. Fuse
The motor protective is located within the switch
cabinet F40, 2.8 – 4A.
It is the overloading protection for the drive motor.
In case the motor protective has been triggered, clear
the cause of the overloading and reactivate the fuse
afterwards.
4.2. Saw blade guiding and saw blade cover
The saw blade guiding is mounted to the saw blade cover. Adjust the saw blade guiding for cutting at
the top in a way that only minimal space remains between the lower edge of the saw blade guiding and
the upper edge of the pipe.
Hold tight to the saw blade guiding, release the fixing handles and shift the saw blade
guiding to the necessary height.
Fix the saw blade cover by the fixing handles.

(Upper saw blade guiding)
The saw blade runs through the identical saw blade guidings on top and bottom.
It is lead through the two rollers and supported to the rear 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 guiding, 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 by means of the counter nut.
4.3. Adjust the cutting radius
In order to adjust the cutting radius,
release both clamping levers.
Shift the swiveling plate until the desired
radius is shown on the measuring tape.
Fix setting with both clamping levers.

4.4. Vacuum device
It is indispensable to exhaust the cutting chips. The guidings for the swiveling plate as well as the saw
blade guiding may become sluggish resp. get damaged by the cutting chips.
Special feature: the vacuum device has two extraction hoses in
order to exhaust the chips at the saw blade and the second one to
exhaust the machine surroundings.
Solid hose at the saw blade: Detachable hose at the base frame:
E.g. shift the extraction hose from one of the vacuums below the guard plate just in front of the saw
blade.
Necessarily secure the vacuum against shifting e.g. by vibration during cutting.
Always activate the vacuum device while cutting.

5. Starting and operating
The instructions of this chapter are supposed to initiate in the operation of the machine and lead
through the appropriate starting of the machine.
This includes: - the safe operation of the machine
- economic operation of the machine.
5.1. Starting
The saw RSR 630 must be adjusted by means of the leveling screws in the machine feet in such a way
that the swiveling plate is horizontal and the saw arm is vertical.
Connect the mains plug to the local power supply 230 V / 16 A / 50 Hz.
It is necessary to attach a vacuum device (chapter: 4.4).
In situations of danger for man and machine immediately release the button resp. pull the
power plug!
Cut only tightly clamped pipes!
Take care that no unauthorized person has access to the band saw.
Protect the band saw from wetness and humidity!
Clean the saw arm regularly with the saw switched-off! (see chapter 6.3 )
Do not 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.

10.04.17 Working instructions WIDOS RSR 630 Page 19 of 28
5.2. 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!
Release the belt by pulling the safety gripper into
direction of the ratchet grip.
In order to make pipe clamping easier, the machine
features a limit stop. The pipe must be shifted towards
this limit stop and then be fixed by the belt.

5.2.1. Adjust angle for branch pipe 45° and 60°
If you want to cut branch pipes with 45° or 60° angles, you must swing the prism accordingly upwards.
Detach both rear hexagon screws “1” and
detach the front hexagon screws “2”.
Mount the fixtures for angle 45° branch or for
angle 60° branch between support and prism
and fix the hexagon screws „2“.
Depending on pipe size and angle it is
necessary to shift the prism in order to minimize
the unprotected pipe overhang.
Release the hexagon screws „3“ and shift
the support including prism on the
necessary distance.
