4.0 INFORMATION ABOUT TRANSPORT & STORAGE
Due to the size of the machine, it should be transported on a forklift or by a crane bridge, using slings.
If the machine is left in storage for a long period of time, lubricate periodically. Do not expose to the
elements. The machine is supplied in a properly designed and sized wood crate, and it is also supplied
wrapped in plastic.
CAUTION: Do not improperly dispose of the packaging. Send the materials to be recycled or
eliminated in accordance with current legislation.
5.0 INSTRUCTIONS FOR ANCHORING & SERVICE START-UP
5.1 ANCHORING INSTRUCTIONS
The machine must first be checked in order to ensure that it has not suffered any damage during
transport. If so, immediately contact the manufacturer.
The machine must be installed on a firm surface that is as level as possible in order to reduce vibrations
during operation and so that it operates according to the parameters established by the manufacturer.
Page 6
5.2 CONNECTION TO THE ELECTRIC SYSTEM
Ensure that the power supply voltage corresponds to the voltage on the data plate of the machine.
Connect the cable (4 x 1.5 sleeve) to the electric system, using a plug that is appropriate for the
characteristics of the same, thereby respecting color codes.
After the machine has been connected, verify that the rotation of the hydraulic power pack motor
agrees with the direction indicated by the arrow shown on the same. If the motor rotation is not
correct, reverse the two phase connections of the line and then, check again.
The pneumatic connection must be made to the supply system using a connector that is appropriate for
the connector on the machine. Adjust the pressure at the filtering group.
5.3 INSTALLING THE BAND SAW BLADE
In order to install the band saw blade:
Lift the frame guard and remove the blade guide guards.
Loosen the tension adjuster.
Put on the band saw blade, sending it through the interior of the guides.
Re-tighten the tension adjuster.
Put on all of the guards.
Turn the saw manually and use a brush to lubricate in between the two guides, using SAE 30
lubricating oil.
ATTENTION: When replacing the band saw blade, always use protective gloves.
DANGER: After changing the band saw blade, put on all guards again. It is absolutely prohibited to
work with them removed.
Page 7
5.4 CUTTING COOLANT
When filling the cutting coolant, use pure, synthetic water-soluble coolant and pour it in through the
coolant down-tube on the machine mount.
CAUTION: When it is necessary to empty the liquid coolant tank, do not improperly dispose of the
coolant.
ATTENTION: The use of any other kinds of coolants may cause irreparable damage to the machine,
as well as diminish the quality of the cut and reduce the life of the saw.
6.0 INSTRUCTIONS FOR USE
6.1 PROPER AND IMPROPER USE
Band saw machine for cutting all kinds of ferrous and non-ferrous materials. Use of the machine for
cutting other materials is prohibited. Such use may cause damage to the machine and risk the safety
of the worker.
DANGER: We are hereby not liable for any possible accident caused by the failure to comply with
the aforementioned provision.
6.2 FUNCTION OF THE OPERATING MECHANISMS
1. The vise is closed using lever no. 1. Work with the vise jaws less than ¼ inch (6 mm) from the
material to be secured.
2. Angle locking lever. Set to position C to allow angled rotation.
Page 8
6.3. RAISING AND LOWERING THE STOP
The machine is fitted with lowering stops and a mechanical safety stop. Use the washer on the arc bolt to
adjust the height.
WARNING: When performing the cut, it is important that the saw should be lowered at a constant
rate, with no sharp changes of speed. If the saw becomes jammed in the material, release the
rotation control and raise the head.
IMPORTANT: Always secure the material with the vise jaws and never by hand.

Check for oil leaks. State of internal flanges.
Tensing mechanism. Flywheel and bearing.
7.1 ADJUSTMENT OF CUTTING BLADE GUIDES
In order to obtain a correctly squared cut, you must make sure that there is a distance of .035
thousandths of an inch (0.9 mm) between the side plates (3), so that they are all in contact with the blade.
To adjust this distance, follow the instructions given below:
1. Loosen screws (1)
2. Place a .035" (0.9 mm) gauge or sheet between the
plates and adjust the distance using the set screw (2).
The gauge must slide smoothly but without
wobbling. (If a gauge is not available, a piece of the
cutting blade from the machine may be used.)
The upper guide assembly may also be exerting excessive pressure on the cutting blade, resulting in a
widening at the upper edge. To prevent this, loosen the screws (6) and slightly raise the blade guide (7).
The guide must be positioned so that after rotating the saw when it is not in contact with any material,
the plate (4) must not exert any downward pressure on the cutting blade when at rest. (There should be a
clearance of .004 (0.1 mm) with the blade.)
7.2. CHANGING THE GUIDE PLATES
Over time, the side plates (3) and the upper plate (4) may need to be replaced. To do so, follow the steps
indicated below:
1. Loosen the screws (1) on both sides of the guide and remover the guide plates.
2. Tap the plate (4) through the hole (5) until it comes out of its housing.
3. Fit the upper plate and then the side plates (3).
4. Adjust the lateral clearance of the plates, as explained in the previous section, ADJUSTMENT OF
CUTTING BELT GUIDES.

10.0 ACCESSORIES
Scotchman has several accessories to help with your sawing needs; the first of which are our Material
Supply Tracks. They are available in 5' and 10' lengths and can be assembled to as long as needed.
The same is true for our Discharge Tracks. They are available with either our Quick-Loc or Multi-Loc
measuring systems, which will save you time and increase your productivity.
The Quick-Loc can be changed quickly from one length to another. It has a 10" extension arm that can
be used to cut short lengths closer to the blade. The whole stop assembly can be flipped up, out of the
way, if needed.
The Multi-Loc can be set up to cut several lengths from one bar of material. These simple and efficient
measuring systems can be used in many applications: drilling - tapping - punching - shearing, as well as
sawing. These tracks and measuring systems can also be purchased in either Left or Right hand
configuration. Please visit Scotchman.com to see a demonstration of how well our measuring systems
work. We think you'll be impressed!
