1 Transport & handling
1.1 Transport
Scantool SC 250 T industrial double-ended grinding machine is delivered on a pallet wrapped in
protective covering.
1.2 Handling
Scantool SC 250 T industrial grinding machine can easily be transported in the packing in which it is
delivered. If the grinding machine is delivered on a pedestal you must make sure that the pedestal is
secured to the transport pallet.
1.3 Placing
Placing of the industrial grinding machine must take place on a firm and level surface. Now tighten the
grinding machine to the floor or the working table by using the four bolt holes used for securing the
machine to the pallet.
The electrical voltage must be within the given ranges shown on the motor label.
The machine must be wired according to the wiring diagram (please see section 5.3).
The wiring must be performed by an authorised installer. Please make sure that the motor has the
correct direction of rotation (please see the arrow on the cover).
Fig.: 1.1
Before operating the machine please control that the outer cover (A) (see fig.: 1.1) is secured to the inner
cover. The outer cover must be mounted during use of the machine and can only be dismounted during
maintenance. The grinding wheel (B) must be able to rotate freely without being loose. The tool rest (C)
must be adjusted to a distance of appr. 2mm from the grinding wheel.
The eye shield (D) must be kept clean and adjusted to the correct position and the spark arrester (E)
must also be adjusted to a distance of 5mm from the grinding wheel and lightly fastened.
All these checks and adjustments can only be made while the machine is disconnected from the power
source.
First time you start up the machine please let it run at maximum speed for appr. 5 minutes before start
grinding. Make sure you are positioned in a safe distance while doing the running test.

2 Operator’s guide
2.1 Operation
After adjustment and connection of the grinding machine it is ready for use. Lead the work piece to the
grinding wheel with a firm and level pressure to avoid destroying the grinding wheel and overloading the
motor. Avoid excessive pressure or uneven grinding. Let the machine run at max speed before start
grinding. Grind at max speed if possible. Clamp the work piece if possible as this is safer than holding
the work piece in your hands.
Avoid grinding on the side of the grinding wheel unless you grind on a cup wheel.
Do not stop the rotation of the grinding wheel by pressing the work piece against it. Let the grinding
wheel stop by itself. It is important to have the work place well-lighted.
2.2 Security
The existing safety rules must be kept in order to avoid personal or material injury when working with the
belt grinder.
A. User
Do not wear loose clothing, gloves, rings, bracelets, or other jewellery to get caught in moving parts.
Non-slip foot wear is recommended. Wear protective hair covering to protect long hair.
Always wear eye protection and face or dust mask if the operation is dusty. Ordinary glasses cannot
replace eye protection.
Do not overreach. Keep proper footing and balance at all times.
Never leave tool running unattended. Turn power off. Do not leave tool until it comes to a complete stop.
Don´t operate tool while under influence of drugs, alcohol, or any medication.
B. Use of Machine
Use right tool. Don´t force tool or attachment to do a job for which it was not designed.
Use recommended accessories. Consult the owner´s manual for recommended accessories. The use of
improper accessories may cause hazards.
C. Adjustment
Make all adjustments with the power off. In order to obtain the machine precision and correct ways of
adjustment while assembling, the user should read the detailed instruction in this manual.
D. Working Environment
Keep work area clean. Cluttered areas and benches invite accidents.
Do not use in dangerous environment. Do not use power tools in damp or wet locations, or expose them
to rain. Keep work area well-lighted.
Keep children and visitors away. All children and visitors should be kept a safe distance from work area.
E. Maintenance
Disconnect machine from power source when making repairs.
Check damaged parts. To read every details of trouble shooting, repair it very carefully and make sure
the operator will not get injured and damage the machine.
2.3 Maintenance
The grinding machine must be placed on a dry place to avoid the grinding wheels from getting wet by
damp or rain.
The grinding wheel often gets uneven during use and therefore we recommend that you make it even
occasionally. We recommend that you replace the grinding wheel when it is worn about 25%. An uneven
grinding wheel causes vibrations which with time destroys the bearings in the machine.
Damaged tool rests, eye shields and covers must be replaced immediately to avoid personal injuries or
material damage.
When the grinding wheel must be replaced first dismount the spark arrester (A) (see fig.: 2.1), then
dismount the outer cover (B). The nut (C) is unscrewed and now the outer flange and the grinding wheel

can be taken off. The new grinding wheel is not allowed to exceed the measures given on the motor sign
on the machine. It is very important that the hole dimension is correct. The grinding wheels are supplied
with labels (discs made of pressed material), which are placed around the holes on both sides of the
grinding wheel. If these labels are damaged or missing they must be replaced by new ones of the same
dimension. The new grinding wheel is mounted between the two flanges (D) and the lock nut (C) is
screwed on and tightened. The lock nut (C) must be tightened enough to hold tight the grinding wheel but
not too tight as this will result in unwanted tension in the grinding heel.

3 Trimming
3.1 Assembling and mounting of trimming attachment/deburring
The deburring cover is assembled as shown in fig.: 3.1. The four screws in the end cover (A) is
unscrewed and the mounting plate (B) is placed on the end cover (A). The four counter sunk machine
screws M6x20 (C) are screwed in. Now the deburring cover (D) can be mounted during the two slits in
the mounting plate (B), the cover can be moved back and forth so that the steel brush (G) can be utilized
better. The inner flange (F) is mounted on the shaft together with the steel brush (G) and the outer flange
(H). Last the lock nut (I) is screwed onto the shaft and tightened. Before the lid for the deburring cover
(D) is closed, the eye shield (J) is mounted (as shown in fig.: 3.1.). If you are not going to trim a pipe you
can dismount the tool rest for pipe trimming (K) and use the flat tool rest below the other one.

Fig.: 3.1
3.2 Changing of the steel brush
When the steel brush is worn about 10 %, it needs replacing. This is easily done by opening the lid on
the deburring cover (D). Dismount the nut (I) and the flange (H) together with the steel brush. The new
steel brush is mounted in reverse order. Often it will be necessary to adjust the tool rest (K) before
placing the new steel brush.
3.3 Maintenance of the deburring/trimming attachment
It is not necessary to do any maintenance on the trimming device besides it is necessary to adjust the
tool rest when the steel brush is worn.
The eye shields and other equipment must be replaced as soon as it is broken or damaged.
3.4 Operation of the deburrer
When the deburring/trimming attachment has been correctly mounted the tool rest (A)
(see fig.: 3.2) must be adjusted by setting the height of the tool rest when the screw (B) is loosened. The
distance to the steel brush is adjusted by loosening the grip (C) below the cover. As mentioned earlier
the tool rest for pipe trimming (A) can be dismounted and the flat tool rest below can be used for
trimming plates or squares.
It is only recommendable to do this adjustment of the tool rest when the machine is not on.

6
Fig.: 3.2
Before starting the trimming operation it is important that the machine runs at max speed and that the
trimming is made at max possible speed. Secure the work piece in clamps or equal, as it is safer than
holding the work piece in your hands. Also it frees both hands to do the operations.
If the motor is slowed down during trimming this can result in burn-out of the motor. The best possible
result can be obtained by leading the work piece slowly towards the steel brush and avoid excessive
pressure against the brush.
Do not the rotation of the steel brush by pressing a work piece against it. Always let the steel brush stop
by itself.
