Use of the most important machine parts

6.1 Power systems and control fitting
The electric output of your band saw is controlled magnetically either via 230 volt alternating current or 400 volt 3-phase current.
Before connecting the machine to the mains supply ensure that the motor shaft is running in the right direction.
We advise you to use mains cable measuring 1,5 mm ² protected with 10 ampere dual-element fine fusing for the power supply to all machines irrespective of their electric output.
Consult the electric wiring plan supplied with the machine for further instructions concerning the question as to how the saw is connected to a power source. The power supply must be disconnected when the band cover is opened or used during repair.
Please check the direction of movement of the band. If the saw teeth move in the wrong direction please reconnect the cable (rotate phases).
6.2 Adjustment of upward and downward movement of saw arm
The downward movement of the saw arm is to be adjusted such that when the saw arm is in its lowest position the teeth of the saw band do not touch the worktop. The stop screw (A) is used to set the spacing between the band and the worktop. After the spacing  has been set, tighten the counter nut.
The screw (B) is used to set the upward angle of the saw arm and tighten the counter nut. 6.3 Adjustment of band tension and track
Turn the band tensioning handle (C) in a clockwise direction to tension the saw band. The scale is graduated enabling the band to be tensioned to suit the quality of the saw band. Slacken the band tension at the end of each working day in order to extend the service life of the band.PROMAC SX 818DV SX 818DV
Metal Band Saw - Unpacking 4

Ensure that the saw band is correctly tensioned prior to checking or adjusting the track. The track of the band is correct if the rear side of the band only touches the flanges of both wheels lightly when the machine is running.
6.4 Adjustment of cutting width
Firstly undo the screw (D). Shift the left-hand band guide rail into the position required. Then tighten the screw (D).PROMAC SX 818DV SX 818DV Metal
Band Saw - Unpacking 5.

6.5 Adjustment of band guide roller bearings, hard metal
band guide and spare bearing and removal of chippings Before making the following settings, ensure that the track and tension of the saw band are correctly adjusted:

  1. The rear side of the band should make contact with the spare block (B). In order to make adjustments, release the setting screw and move the guide block upwards or downwards until it touches the rear side of the band lightly.
  2. The saw band should also touch the two band guide roller bearings lightly and lie between them (E). The front bearing is located on an eccentric mounting and can be adjusted easily to suit the band thickness by loosening the nut and turning the shaft (F).
  3. The band guide bearings (E) should also be adjusted so that they make light contact with the band (F).

6.6 Instructions for handling the quick-clamp vice system
For operation purposes proceed as follows:
Lift the arm 5 cm above the workpiece. Shut the control valve to hold the arm 2 cm above the workpiece.
Place the workpiece on the worktop. Move the handle of the vice (A) up to an angle of 45 degrees (semi-opened) to release the vice. Move the vice slides up against the workpiece by turning the handle (B). Press against the vice handle (A) to fix the workpiece in place.
To release the workpiece from the vice, hold the workpiece and lift the vice handle (A) to an angle of 90 degrees (fully opened). Remove the workpiece. FURTHER CUTTING:
If you wish to make multiple cuts to a workpiece, all you have to do is lift the vice handle (A) in order to release the workpiece or change its position. Press on the same handle to then fix the workpiece in place. You can also press the vice handle (A) downwards first and then tighten the vice by turning the handle (B) in a clockwise direction. Once the cuts have been made, you can release the workpiece by turning the handle. This quickclamp vice system has a tightening path of 4 mm when the rectangular handle is fully opened. For normal metallic materials, a tightening path of 2 mm is all that is required. The user can tighten the workpiece by pressing the vice handle (A) downwards with appropriate pressure to suit the hardness of the workpiece.
6.7 Adjustable cutting angle option
Please proceed as follows to select the cutting angle required. The pivoting range is in a clockwise direction from 0 ° to 60 °. Before pivoting the base ensure that nothing is in the way and that there are no other hindrances.

  1. Pull the handle (A) out.

  2. Press it to turn the pivoting base to the angle required.
    Observe the scale on (B) for the number of degrees.

  3. Fix the handle (A) in place and start cutting.

  7. Locate the new saw band on the band wheels and in the band guides and adjust the band tension and band guides to suit.

Maintenance

It is easier to keep the machine in good condition by way of ongoing maintenance than it is to repair it if it breaks down.
Daily maintenance (by user)
(a) Replenish the lubricant each day prior to the initial operation of the machine.
(b) If the gearbox is overheating or making strange noises, stop the machine immediately so that it can be inspected.
(c) Keep your work area clean; release the vice, blade and workpiece from the worktop; disconnect the power supply, remove the chips and dust from the machine and follow the instructions on lubricating or coating with rust-free oil before leaving the workplace.
Weekly maintenance
(a) Clean the vice spindle and lubricate it lightly with oil.
(b) Check whether the side face and pivoting parts have sufficient lubricant. If there is insufficient lubricant, this should be replenished.
Monthly maintenance
(a) Check whether any fixed parts have come loose.
(b) Replenish gearbox oil if required in order to avoid wear and tear.
Annual maintenance
(a) Check the worktop in its horizontal position in order to ensure that its precision is maintained.
(b) Check the electric cables, plugs and switches at least once a year to avoid any accidental loosening or wear.

Choosing the saw band

Choose a too thing that is appropriate to the workpiece being processed. Ideally, at least 3 teeth should be in action at the same time.
The too thing should not be smaller than necessary, as the cutting speed is reduced if there are too many small teeth working on the workpiece simultaneously, which causes the saw band to wear more quickly, and makes the cuts crooked and distorts them.
The following table shows the approximate too thing of the saw bands for a specific material thickness. For further information please contact your saw band dealer. Comments
10/14 tooting provides good cutting results for thin walled pipes and profiles.
The choice of tooting (i.e. the number of teeth per inch) should be such that at least 3 teeth are always in action at the same time.
When cutting thick material, a coarse Tooth Pitch “T” is needed to accommodate the big chips. Cutting speed selection
The general rule is the harder the material being cut, the slower the blade speed.
20 m/min
for stainless steel, alloy steel and bearing bronzes.
30-50 m/min
for mild steel, hard brass or bronze.
60-85 m/min
for soft brass, aluminium or other light materials.
Saw band lubricant
The lifetime of the saw band can be extended significantly by lubricating it with stick wax item no. 100103.
NOTE
Some materials, such as stainless steel or aluminium, require specific oils.
Rounding of teeth
A carefully broken in blade lasts much longer and gives better performance. To break in your new blade, run it at only 30% of normal pressure for ten minutes.
Then gradually increase to normal pressure.
Feed pressure selection:
A good indication of proper feed pressure is the shape of the cutting chips.
Perfect:
Loose curled chips

If the chips are thin or powdered increase the feed pressure.
If the chips are burned reduce the cutting speed and decrease the feed pressure.
8.1 Blade structure
Bi-metal blades are the most commonly used. They consist of a silicon-steel blade backing by a laser welded high speed steel (HHS) cutting edge. The type of stocks are classified in M2, M42, M51 and differ from each other because of their major hardness due to the increasing percentage of Cobalt (Cc) and molybdenum (Mo) contained in the metal alloy.
8.2 Blade type
They differ essentially in their constructive characteristics
– Shape and cutting angle of tooth,- Pitch REGULAR TOOTH: Oº rake and constant pitch. Most common form for transversal or inclined cutting of solid small and average cross-sections or pipes, in laminated mild steel and gray iron or general metal.
POSITIVE RAKE TOOTH: 9º – 10º positive rake and constant pitch.

Particular use for crosswise or inclined cuts in solid sections or large pipes, but above all harder materials (highly alloyed and stainless steels, special bronze and forge pig iron).
COMBO TOOTH: pitch varies between teeth and consequently varying teeth size and varying gullet depths. Pitch varies between teeth, which ensures a smoother, quieter cut and longer blade life owing to the lack of vibration.

Another advantage offered in the use of this type of blade in the fact that with an only blade it is possible to cut a wide range of different materials in size and type.
COMBO TOOTH: 9º – 10º positive rake.

This type of blade is the most suitable for the cutting of section bars and large and thick pipes as well as for the cutting of solid bars at maximum machine capacity.
Available pitches: 3-4/4-6.
SETS
Saw teeth bent out of the plane of the saw body, resulting in a wide cut in the workpieces REGULAR OR RAKER SET: Cutting teeth right and left, alternated by a straight tooth.

mm. Used for the cutting of steel, castings and hard nonferrous materials.
WAVY SET: Set in smooth waves.

This set is associated with very fine teeth and it is mainly used for the cutting of pipes and thin section bars (from 1 to 3 mm).
ALTERNATE SET (IN GROUPS): Groups of cutting teeth right and left, alternated by a straight tooth.

This set is associated with very fine teeth and it is used for extremely thin materials (less than 1mm).
ALTERNATE SET (INDIVIDUAL TEETH): Cutting teeth right and left. This set is used for the cutting of nonferrous soft materials, plastics and wood.
