Assembly of the sub-frame and wheels (Fig. 3-5/27)

• First attach the legs (21) loosely to the base plate (5) of the machine using 2 screws for each leg. Use the round head M8x12 screws to do so.
• Screw the 2 long struts (41) and the 2 short struts (42) loosely to the legs (21). The doubled-over part of the struts must be at the top.
• Attach the rubber feet to the legs (21).
• Place the machine onto the legs
• Align the entire base frame and tighten all screws.
• Fasten the holder (29) for the push stock (28) as follows: Screw the lock nut onto the bolt (29) and then screw this into the housing until the push stick (28) can be hung up.

Assembling the saw table (Figures 6-9)

• Slacken the wing nuts (45) on the underside of the saw table (15) and remove the chain bar (2) from the saw table.
• Lead the blade through the slot (a) in the machine table and place the machine table on the table guide so that the clamping screw (47) fits through the mounting (48).
• Screw the saw table tight with the wing nut (18).
• Place the chain bar (2) onto the saw table (15) so that the screw heads (50) slide into the guide slots (51).
• Check that the blade (25) runs freely and does not touch the saw blade.
• To remove the saw blade guard, proceed in reverse order.

Tensioning the blade

• CAUTION! Remove the tension from the blade if the bandsaw is not going to be used for some time. Be sure to re-tension the blade before you start the machine.
• Turn the tightening screw (9) for tensioning the blade (25) in a clockwise direction.
• The correct blade tension can be checked by applying pressure to the side of the blade with your finger, somewhere in the middle between the two blade pulleys (7+8). You should only be able to bend the blade (25) very slightly (approx. 1-2mm).
• CAUTION! The blade may break if the tension is too high. BEWARE OF INJURY! If the tension is too low, the powered blade pulley (7) will spin while the blade does not move.

Adjusting the blade

• Undo the fasteners (13) and open the side cover (12).
• Turn the upper blade pulley (8) slowly in a clockwise direction. The blade (25) should run centrally on the blade pulley (8). If it does not, the angle at which the upper blade pulley (8) tilts must be adjusted.
• If the blade (25) runs more towards the rear of the blade pulley (8), i.e. towards the machine housing (24), the setting screw (22) must be turned in an anticlockwise direction. Then turn the blade pulley (8) slowly with the other hand to check the position of the blade.
• If the blade (25) runs towards the front edge of the belt pulley (8), the setting screw (22) must be turned in a clockwise direction.
• After adjusting the upper blade pulley (8), check the position of the blade (25) on the lower blade pulley (7). Again, the blade (25) should run in the middle of the blade pulley (7). When adjusting the upper blade pulley you have to turn it several times until the adjustment affects the position of the blade on the lower blade pulley.
• When the adjustment has been completed, close the side cover (12) again and secure it with the fasteners (13).

Adjusting the blade guide (Fig. 11-13)
Whenever you change the blade you must reset both the support bearings (30+31) and the guide pins (28+29).

Upper support bearing (Fig. 11)

• Undo the screw (33).
• Move the support bearing (30) s that it is almost touching the blade (25). There should be a gap of approx. 0,5mm.
• Re-tighten the screw.

Setting the lower support bearing (31)

• Disassemble the saw blade (15).
• Adjust in the same way that the upper support bearing was adjusted.
• The blade (25) is only supported by the support bearings (30+31) during cutting. During the idle run, the blade should not touch the ball bearings.

Setting the upper guide bearings (Figure 11)

• Undo the screw (35).
• Move the mount (36) of the guide bearings (28) so that there is a gap of approx. 1mm between the front edge of the guide bearings (28) and the gullet of the blade in front.
• Re-tighten the screw (35)
• CAUTION! The blade will be rendered useless if the teeth touch the guide bearings while the blade is running.
• Undo the screws (37)
• Move the two guide bearings (28) towards the blade so that there is a gap of approx. 0,5mm between the guide bearings (28) and the blade (25).
• Re-tighten the screws (37).
• Turn the upper blade pulley (8) several times in a clockwise direction.
• Check the setting of the guide bearings (28) again and re-adjust If necessary.

Setting the lower guide bearings (29) (Fig. 12/13)

• Disassemble the saw table (15) (see 7.2)
• Undo the screw (40)
• Move the mount of the guide pins (29) so that there is a gap of approx. 1mm between the front edge of the pins (29) and the gullet of the blade in front.
• Re-tighten the screw (40).
• CAUTION! The blade will be rendered useless if the teeth touch the guide pins while the blade is running.
• Undo the screws (38).
• Move the guide pins (29) towards the blade so that there is a gap of max. 0,5mm between the guide pins (29) and the blade (25). (The blade must not jam).
• Re-tighten the Allen screws (38).
• Turn the lower blade pulley (7) several times in a clockwise direction.
• Check the setting of the guide pins (29) again and re-adjust if necessary.

Adjusting the upper blade guide (11) (Fig. 2/14)

• Undo the fixing handle (20).
• Turn the adjustment wheel (19) to lower the blade guide (11) as close as possible to the workpiece to be cut (the gap should be approx. 2-3mm).
• Re-tighten the fixing handle (20).
• Check the setting before each cut and re-adjust if necessary.

Adjusting the saw table (15) to 90° (8/15)

• Move the upper blade guide 811) to the top.
• Undo the fixing handles (18).
• Set the angle (d) between the blade (25) and the table (15).
• Tilt the table (15) by turning it so that the angle between it and the blade (25) is precisely 90°.
• Re-tighten the fixing handles (18).
• Undo the screw (52) of the pointer of the dial scale (16), set the pointer to exactly 0° and tighten the screw (52) again.

Blade selection
The blade supplied with the bandsaw is designed for all-purpose use. When you select a blade you should have regard to the following criteria:

• Use a narrow blade to cut tighter radii than you can with a wider blade.
• Wide blades are used to saw straight cuts. This is particularly important in cutting wood because the blade tends to follow the grain of the wood and thereby deviate easily from the cutting line.
• Finely-toothed blades provide smoother cuts but are slower than coarse blades.

IMPORTANT: Never use warped or lacerated blades!

Replacing the blade (Figure 16)

• Move the blade guide (11) into a position approximately half way between the table (15) and the machine frame (24).
• Undo the fasteners (13) and open the side cover (12).
• Remove the chain bar (2).
• Turn the tightening screw (9) anti-clockwise to remove the tension from the blade (25).
• Remove the blade (25) from the blade pulleys (7,8) and take out through the slot in the table (15).
• Fit the new blade (25), aligned centrally on the blade pulleys (7,8).
• The teeth of the blade (25) must point downwards in the direction of the table.
• Tension the blade (25) (see 7.2)
• Close the side cover (12) again.
• Mount the web panel (4) again.

Changing the rubber tires on the blade pulleys (Fig. 17)
After a certain time the rubber tires (3) on the blade pulleys (7,8) will get worn by the sharp teeth of the blades and must be replaced.

• Open the side cover (12).
• Remove the blade (25) (see 7.7)
• Lift the edge of the tire (3) with a small screwdriver (f) and remove it from the blade pulley (8).
• Repeat for the lower blade pulley (7).
• Fit the new rubber tire (3), mount the blade (25) and close the side cover (12) again.

Changing the table insert (Fig. 18)
To prevent increased likelihood of injury the table insert (17) should be changed whenever it is worn or damaged.

• Dismantle the saw table (15) (see 7.2).
• Push out the worn table insert (17).
• Fit the replacement table insert by following the above in reverse.

Extractor port
The bandsaw is equipped with a 100mm extractor socket (6) for extracting sawdust and chips.

Adjusting the blade speed (Fig. 28)
The bandsaw can be operated at two-blade speeds. To change the position proceed as follows:

• Slacken the drive belt (54) by turning the hand wheel (4) in an anticlockwise direction.
• Move the belt to the desired position on the belt pulley (55) and the lower blade pulley (7). The blade speeds are indicated on the inside of the side cover.
• Tension the drive belt (54) again by turning the hand wheel (4) in a clockwise direction. Important: Drive belts must not be tensioned too much!

OPERATION

ON/OFF switch (Fig. 19)

• To turn the saw on, press the green button (g).
• To turn the saw off again, press the red button (h).

Your bandsaw has a switch with undervoltage release. After a power failure, you must reactivate the switch

Parallel stop (Fig. 20/21)
The parallel stop is used as a guide in slitting.

• Place the parallel stop (23) onto the chain bar (2) on the left or right and set the desired dimension.
• Clamp the parallel stop in the desired position by pressing the clamping lever (27)
• The chain bar can be used for thinner workpieces as shown in Figure 20 and for thicker workpieces as shown in Figure 21.

Angular cuts (Figure 8/22)
To enable you to perform angular cuts parallel to the blade (25), the table (15) can be tilted forwards between 0° -45°.

• Undo the fixing handle (18).
• Tilt the saw table (15) forward until the required angle value has been set on the man scale (16).
• Re-tighten the fixing handle (18).
• Important: When the table (15) is tilted, place the parallel stop (23) to the right of the blade (25) looking in the direction in which you are working, on the side pointing downwards. (provided the workpiece is wide enough) to stop the workpiece from slipping off.

OPERATION ADVICE

Important! After every new adjustment, we recommend you to make a trial cut to check the new settings.

• For all cutting operations it is important to position the blade guide (11) as close as possible to the workpiece.
• Always guide the workpiece with both hands, holding it flat on the table (15) to prevent the blade (25) from jamming.
• Feed the workpiece at a uniform speed that enables the blade to cut through the material without difficulty and without blocking.
• Always aim at making a complete cut in one pass rather than in a stop-and-go operation requiring the workpiece to be withdrawn. If you have to withdraw the workpiece, switch off the bandsaw first and wait for the blade (25) to stop before freeing the workpiece.
• The workpiece must always be guided by the longer side during cutting.

Important!
When handling narrower workpieces, it is essential to use a push stick. The push stick (28) must always be kept close at hand at then hook(29) provided for that purpose on the side of the saw (Fig. 27).

Longitudinal cuts
A longitudinal cutting (also known as slitting) is when you use the saw to cut along the grain of the wood.

• Place the parallel stop (23) to the left of the blade (25), as far as possible, for the width required.
• Lower the blade guide (11) down to the workpiece.
• Switch the saw on.
• Press the edge of the workpiece with your right hand to hold it securely against the parallel stop (23) and flat on the table (15).
• Guide the workpiece along the parallel stop (23) and through the blade (25) at a uniform speed.
• Important: Long workpieces must be secured against falling off the table at the end of the cut-

Freehanded cuts (Figure 25)
One of the most outstanding features of a bandsaw is the ease with which it allows you to make curved cuts and radii.

• Lower the blade guide (11) down to the workpiece.
• Switch on the saw.
• Hold the workpiece securely on the table (15) and guide slowly through the blade (25).
• Freehanded cuts should be made at low feed speed so that you can guide the blade (25) along the required line.
• It often pays to first cut off surplus curves and corners up to about 6mm from the cutting line.
• In the case of curves that are too tight for the blade to cut correctly, it can help to make a series of close-lying cuts at right angles to the curved line. When you saw the radius the material simply will drop off.

MAINTENANCE

Important! Pull out the power plug first. Remove the dust and dirt regularly from the machine. Cleaning is best carried out with a fine brush or a cloth. Never use caustic agents to clean plastic parts.
