Operating and indicating elements Chapter 4


4.1. Elements to lock the saw arm

The saw arm features below lug 2 with two drill holes. The locking bolts are stored in the lug.

The revolving plate features lug 1 and 3.

In order to make straight cuts, you must not lock the saw arm.

The locking device from lug 2 to lug 3 is meant for the optional circular cutting.

Lock lug 2 to one of the drill holes in the basic plate (chapter 4.3) in case you want to cut an angle.

Lock lug 2 to lug 1 in 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).

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; using all the possible options of the machine; the economic operation of the machine.

5.1. Starting

In order to start the operation, the band saw RS 315 has to be adjusted by means of the screws in the machine feet in such a way that the pipe support and the saw blade guidance are horizontal.

Connect the mains plug to the local power supply 400 V / 16 A / 50-60 Hz. Connect the pressure regulator (optional) to the local compressed air supply (6-8 bars).

Remove the locking bolt on the right side from lug 1 (chapter 4.1).

It is necessary to install a vacuum; a connecting piece is available at the right saw arm in the front (chapter 4.1).

In situations of danger for persons and the machine, the emergency-off has to be pushed immediately or the mains plug has to be unplugged! Cut only firmly clamped pipes!

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. Take care that no unauthorized person has access to the band saw.

Protect the band saw from wetness and humidity!

The saw arm has to be cleaned regularly – switch off the saw for that purpose! (see point 6.4)

5.1.1. How to adjust the compressed-air regulator

Slowly pressurize the complete system.

Pull the pressure setting button left (away from the housing).

Turn the pressure setting until the desired pressure is shown on the pressure gauge. The input pressure must be at least 1 bar greater than the output pressure.

Press the pressure setting button to the right (towards the housing) to secure it against unintentional turning.

Starting and operating Chapter 5


5.2. How to make straight cuts

Check whether the wide saw blade (13 mm) is mounted, if necessary replace it.

Adjust the saw blade cover onto the corresponding height in relation to the pipe (chapter 4.4).

The saw has not been swiveled, the pointer of the scale is exactly on position 0° (see chapter 4.3) and the clamping levers of the swiveling device are tightened.

Lay the pipe onto the pipe support in such a way that the cutting edge is in front of the saw blade.

Switch on the optional laser at the slide switch (see point 4.4) and verify the cutting edge (the later course is optically indicated).

Clamp the pipe either with the manual clamping lever and turn the pipe clamper manually onto the pipe center at the same time.

Or clamp the pipe with the clamping belt.

Move the saw blade with the hand grip until it is just in front of the pipe.

Switch on the local exhaust.

Take care that no part of a body or foreign object is in the sawing area. Switch on the saw by pushing the push button on the top of the grip (or tread on the optional foot switch).

Pull the saw arm forwards in order to start cutting. Release the push button (optionally foot switch) and push the saw behind the pipe again.

The saw still runs for appr. 3 sec after having released the push button.

Switch off the vacuum again.

Now the pipe can be unclamped by actuating the manual clamping lever and be removed.

Remove the cuttings and the remaining pieces.

5.3. How to cut angles

Check whether the wide saw blade (13 mm) is mounted, if necessary replace it.

Release the clamping lever on the swiveling device and adjust the saw onto the desired angle (up to max. 45° on both sides / 67.5° on one side) and tighten again the clamping lever.

Clamp the pipes and perform the cutting as described in chapter 4.5.

5.4. How to mount the circular cutting device (optional)

In case of branch pipes, you have to use the 13 mm saw blade.

You may use the 10 mm saw blade (optional) in order to cut small radii.

There are rollers for each saw blade width that must be also replaced upon changing the saw blade width (for this, please see chapter 6.6).

Make sure upon mounting and dismounting the circular cutting device that it does not swivel unintentionally. Secure the device by a belt.

Otherwise you may crush your hands and fingers.

For saws with additional right pipe support (optional), you must dismount this pipe support before mounting the circular cutting device.

Dismount the two pan-head screws and remove the suction funnel.

Drive the saw arm to the front until the drill holes match lug 2 and lug 3 on the right side (chapter 4.1).

Put the locking bolt into both drill holes in order to lock the saw arm

Take up the circular cutting device e.g. by a lifting device and put it to the front and the right side of the saw arm. Make sure that you do not damage the saw blade.

Put a belt around both beams in order to secure the device against unintentional swinging.

Mount the circular cutting device in the frontby four pan-head screws (M8) and washers.

Retaining block

Mount the circular cutting device in the rear by a hexagon socket screw (M8) and washer.

Check the installation of the circular cutting device.

The prism being horizontal must be located to the saw blade in an entirely right angle.

If necessary slightly detach the fixing screws, adjust the angle until the device is in rectangular position and tighten the screws again.

5.5. How to adjust the circular cutting device

As soon as the circular cutting device is mounted it must be adjusted to the radius to be cut. The gap from the device’s center of rotation to the saw blade is the cutting radius, equaling ½ outer diameter (OD) of the main pipe to which the cut branch pipe is to be welded.

5.5.1. How to adjust the cutting radius

The sawing radius is adjusted by three screws.

For its displacement detach the screws and push the device to the necessary dimension at the slotted holes, then tighten the screws again.

At the front adjuster, one screw has to be displaced according to the cutting radius. From outer diameter main pipe smaller than OD 320 mm to outer diameter OD 320 up to 480 mm.

Main pipe

Branch pipe 90° Branch pipe 45°

Sawing radius = ½ outer diameter main pipe

The rear fixing screw also serves to the radius’ adjustment

Adjust screws to the radius




5.5.2. 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 screws in the rear from prism and support, swivel the prism upwards and mount the long fixings for angle 45° - branch, the short fixings for angle 60°.

5.5.3. How to adjust the gap from saw blade to pipe support

The cutting course should possibly be close to the pipe support. For this purpose, the prism can be continuously adjusted.

Swivel the circular cutting device in a way that the saw blade is next to the prism center. The gap of leading edge + prism center to saw blade should be appr. 10 - 20 mm. In order to adjust the gap, detach the rear screws of the prism and swivel it upwards. Now detach the screws on the support, displace them to the desired gap and tighten the screws again. In case no angle has to be cut, fix the prism to the support again.

Carry out a swinging motion with raised prism but without pipe. The prism must not touch the saw blade!

5.6. How to clamp and cut branch pipes

The prism features two slots in order to hook in the belt. Always clamp the pipes as close as possible to the sawing cut.

Adjust the saw blade cover just shortly above the pipe (Chapter 4.4).

Put on the pipe and tightly clamp it by the belt (Chapter 4.6.1), thereby avoid deforming thin-walled pipes.

Adjust the gap between center of rotation and saw blade to ½ OD of main pipe (as described in chapter 5.5.1).

Activate the saw motor by pressing the push-button at the saw frame handle or by treading the optional foot switch.

Carefully swivel the pipe against the running saw blade by the swivel arm handle and cut the pipe through.

Release push-button or foot switch and wait for the saw blade to stand still.

Now you can unclamp and take out the pipe, and remove the reject.




6. Maintenance / Storage / Transport Goal of the chapter is:

Keeping the nominal state and the operation capacity of the machine.

Efficient planning of the maintenance work and the maintenance tools.

Increasing the efficiency by avoiding non-planned outage.

6.1. In general

All maintenance and repair work have to be basically performed with the machine in off position.

During this, the machine has to be secured against unauthorized switching on, e.g. by disconnecting the mains plug.

Prescribed maintenance and inspection work should be performed in time. We recommend inspection work after 1 year.

For machines with especially high usage percentage, the testing cycle should be shortened.

The work should be performed at the WIDOS GmbH company or by an authorized partner.

You must clean the linear guidings weekly e.g. with a brush.

Check the linear guide carriages every 12 months and grease via lubricating nipples if necessary.

Guidings may jam and run roughly due to dirt.

The operating staff has to be informed before starting maintenance work.

Check the tightness of all screwed connections every three months.

Replace damaged parts immediately. Be particularly careful with electric parts - dust and humidity are very much current conducting.

Only use original WIDOS spare parts for repair work.

Store dry.

Protect the machine from heavy shocks.

Handle the machine carefully.

6.2. Storage

If any storage becomes necessary, make sure that the storage room is dry and that the temperature is between +5°C and +35°C.


Maintenance / Storage / Transport Chapter 6


6.3. Transport

It is not necessary to disassemble the saw for the transport.

Push the saw arm to the front.

Secure the saw arm on the right hand side by inserting the locking pin in tab 2 and 3 (see also chapter: 4.1.

6.4. How to remove the cutting chips from the saw blade housing

Clean the saw blade housing from cuttings regularly. For that purpose disconnect the mains plug. Release the star screw and put saw blade housing completely downwards.

Open up the two locks at the saw arm.

Open up the door on the left side (if necessary turn saw arm to the right) and remove all cutting chips.

Afterwards, shut saw arm again.

Connect the mains plug again to the local mains supply.

6.5. How to tension and adjust the saw blade

The saw blade is tensioned on the right side of the saw arm at the center deflection pulley. Release the counter nut with fork wrench size 30. Turn the eccentric with ring-fork-wrench 16 until the saw blade has the desired tension. Then secure the eccentric with the counter nut again.

The saw blade must run on the center of the pulleys. In case that it runs unevenly, check if the saw blade is in central position.

First disconnect the mains plug, t put saw blade housing completely downwards and open the saw arm.

The center position can be set on both deflection pulleys.

For that purpose release the fixing screws, then turn the set screws somewhat in or out (they rest on the faces of the deflection pulleys) if necessary.

Finally turn the saw blade manually (wear safety gloves!) in moving direction in order to check if it runs evenly.

If so, tighten again the fixing screws and close the saw blade housing.

Connect again the mains plug.

6.6. How to exchange the saw blade

Danger of injuries!

The tips of the saw teeth are sharp - for that reason wear safety gloves!

The saw blade is driven by the saw motor with drive wheel and runs over two deflection pulleys in the saw blade housing.

Disconnect the mains plug in order to exchange the saw blade.

Open the saw arm on the left side.

Release the saw blade tension (see chapter: 6.5) and disassemble the cover of the saw blade guiding below.

Release the tension of the idle pulleys by means of an eccentric bolt at the top and bottom (see chapter 4.2).

Now remove the saw blade. If you change the saw blade width, then replace the idle pulleys now (chapter: 6.6.1)

Deflection pulleys

Drive wheel

Cover of lower sawblade guiding

Set screw Fixing screw




Lay the new saw blade over the drive wheel and the deflection pulleys with the teeth showing to the backside of the housing.

Then turn the saw blade in the cutting area in such a way that the teeth show to the front (see photo on the left).

Remount the cover for the saw blade guidance. Reset the upper and the lower saw blade guidance (see point: 6.5).

Now tension again the saw blade. Check by turning manually if the saw blade runs on the center of the pulleys, adjust it if necessary (see point: 6.5).

Then close the saw blade housing, tighten the screws and connect again the mains plug.

6.6.1. How to replace the rollers

The rollers are axially sustained on the bearing and eccentric bolt by safety rings.

For the saw blade being 10 mm wide, there are rollers with a large bevel in order that the saw teeth do not run on the roller.

In order to replace the rollers (above and below), remove the safety rings and then pull off the rollers to the front. Push the new rollers onto the bolts with the large bevel showing to the front and mount the safety rings again afterwards.

6.7. Disposal

At the end of their lifetime, the machine and the wear parts have to be disposed of properly and non-polluting, and in accordance with the national laws of waste disposal.
