Definition of terms
Kerf
The gap formed when material is removed by the moving blade.
Cutting line
The line along which the blade cuts through the workpiece.
Saw set
A saw blade's teeth are alternately set slightly outward in order to prevent the blade jamming in the kerf. The kerf is therefore wider than the blade thickness.
Workpiece
The object being cut. The surfaces of a workpiece are usually referred to as the top, bottom, front edge and rear.
Longitudinal cutting
Sawing along the grain of the wood.
Angle cutting
Cutting at an angle to the surface of the workpiece that is not a right angle.
Mitre cutting
Cutting at an angle to the front edge of the workpiece that is not a right angle.
Double mitre cutting
A combination of angle and mitre cutting.
The bandsaw must only ever be operated from the front or side.
Be sure not to install or operate the bandsaw in damp or wet conditions.
7. Assembly (Figure 1/2)
Caution! Pull out the power plug before carrying out any maintenance or resetting work on the bandsaw!
The bandsaw is preassembled at the factory. All you have to do is fasten the machine table (13) to the machine stand with the quick-release clamping screw. Ideally you should bolt the bandsaw to a solid worktop or workbench using the holes provided in the machine foot. Check the data on the rating plate. Voltage and frequency have to comply.
7.1 Adjusting the cutting height
The upper blade guide has to be adjusted in accordance with the thickness of the workpiece. Undo the fixing screw (2) and adjust the blade guide so it is approx. 2-3 mm higher than the thickness of the workpiece you want to saw. Re-tighten the fixing screw. Check the setting before every cut and re-adjust if necessary.
7.2 Changing the blade
Caution! Pull out the power plug before changing the blade.
The blade is sharp! Beware of cutting yourself! Wear safety gloves when carrying out any work on and with the blade.
- Undo the fixing screw (2) and move the upper blade guide unit to a position approx. half way between the table and the frame.
- Release the two machine frame locks and open the housing cover.
- Undo the two fastening screws of the blade guard and remove the guard.
- Remove the table adjusting screw, washer and thumb nut from the bandsaw table.
- Move the blade through the slot in the table as far as the middle of the table, making sure that the teeth face the front edge of the table and the tips of the teeth point down.
- Remove all tension from the blade by turning the tension button down.
- Now place the blade on the two blade pulleys and align centrally on the pulley tyres (the rubber surface on the pulleys).
Important!
Remove the tension from the blade if you are not going to use the bandsaw for a while. Place a notice to this effect on the machine where it cannot be overlooked. Be sure to re-tension the blade before you re-start the machine.
7.3 Tensioning the blade (Figure 5)
Caution!
Make sure the blade is tensioned before you switch on the machine. The blade tensioning device has to be locked.
Important!
The blade may break if the tension is too high. Beware of injury!
If the tension is too low, the powered blade
GB
pulley will spin while the blade does not move.
-
Turn the knurled screw (5) anticlockwise until the spring (12) is under no tension. » Starting position!
-
Turn the knurled screw (5) clockwise until the spring begins to tension.
-
Leave the knurled screw (5) in this position and see Point 4.
-
Setting the blade tension on blades of various thicknesses:
1/8" blade: Point 2 setting plus 1 complete turn
1/4" blade: Point 2 setting plus 2 complete turns
3/8" blade: Point 2 setting plus 2 complete turns
7.4 Adjusting the blade (Figure 5)
The blade tension has to be set correctly before you can adjust the blade.
- Slowly turn the upper blade pulley clockwise by hand. The blade should run in the middle of the pulley tyre. If it does not you will have to adjust the tilt of the upper blade pulley.
-
The knurled screw (6) for adjusting the blade run is situated at the back of the machine frame in the middle. Use this screw to adjust the run. Keep the side cover open while making the adjustment. Turn the guide pulleys by hand to check the run. Remember that the blade runs from top to bottom.
-
If the blade tends to run to the back, turn the screw (6) clockwise while turning the blade pulley by hand until the blade runs in the middle.
-
Now check the blade run on the lower blade pulley. The full width of the blade should rest on the pulley tyre. Check that the position of the upper blade pulley runs centrally.
-
Before you switch on the machine, turn the upper blade pulley vigorously several turns by hand to see whether the blade runs off the pulleys. If it does, you must re-adjust the upper blade pulley.
7.5 Adjusting the blade guide
Adjust the upper and lower blade guide after you have adjusted and checked the blade tension. The guide pins of the upper and lower blade guides have to be set to leave a gap of a maximum 1 mm to the right and left of the blade. Adjust the support bearing so that the back edge of the blade runs on the outer ring of the bearing. The support bearing is designed to support the blade on deep cuts in order to guarantee perfect cutting.
Important!
The blade will be rendered useless if its teeth touch the guide pins while the blade is running. Correct adjustment of the upper and lower blade guide is vital, therefore, if your blade is to serve you for a long time.
7.6 Upper blade guard
Adjust the blade guard to leave a gap of a maximum 5 mm between the workpiece and the guard. As a general rule, keep the gap as small as possible.
7.7 Brake system (Figure 6)
The bandsaw's brake system needs regular attention. The bandsaw brake takes the form of a wheel brush which is situated inside the housing cover. Please contact your dealer when the wheel brush is worn. Check the wheel brush in regular intervals before starting the machine. To adjust the brake:
- Undo the screw (1) and move the brush (2) to the correct position.
- Re-tighten the screw (1).
7.8 Cross fence
The cross fence is designed to guide the workpiece safely when making cross cuts or mitre cuts. The cross fence has a 45^ dial scale on both sides for mire cutting.
7.9 Parallel fence
The workpiece is guided along the parallel fence to make straight longitudinal cuts. The parallel fence can be adjusted to the required cutting width.
8. Operation
For all cutting operations it is important to position the blade guide as close as possible to the workpiece.
This will ensure safe operation as well as cuts of optimum quality.
Always guide the workpiece with both hands, holding it flat on the table in order to prevent the blade from jamming. Feed the workpiece at a speed that enables the blade to cut through the material without difficulty.
Always use the parallel fence or the cross fence on all cuts for which they are intended. This will prevent the blade from leaving the cutting line, particularly
GB
when working with a tilted table.
Plan your work steps in advance. Follow the old rule: "It's better to measure twice and cut once than to measure once and cut twice!" 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 to stop before freeing the workpiece. Remember that the blade produces a kerf. Adjust the cutting width accordingly so that the kerf lies in the off-cut section of the workpiece.
After every new adjustment we recommend you to make a trial cut in order to check the new settings.
8.1 Longitudinal cuts
Longitudinal cutting is when you use the saw to cut along the grain of the wood.
It is possible to make freehanded cuts along a marked line. You will achieve better results, however, if you guide the workpiece along the parallel fence. For right-angled cuts (with the table at right angles to the blade), place the parallel fence to the left of the blade so that you can guide the workpiece safely along the fence with your right hand. For mitre cuts with the table tilted, place the parallel fence to the right of the blade on the downward pointing side (provided the workpiece is wide enough) in order to stop the workpiece from slipping off.
8.2 Cross cuts
Cross cutting is when you use the saw to cut at right angles to the grain of the wood. It is also possible to make freehanded cross cuts. We recommend using the cross fence, however, in the interest of safety as well as precision. The cross fence can be adjusted to angles of up to 45^ for mitre cuts. With the table tilted it is also possible to make double mitre cuts.
Hold the workpiece securely against the cross fence and flat on the table. Watch your fingers, particularly toward the end of the cut. Keep away from the blade. Small workpieces should be held by a screw clamp. The cross fence can be equipped with a limit stop to enable several workpieces to be cut exactly to the same length. You can also use this limit stop as a support when working with the table tilted.
8.3 Freehanded cuts
One of the most outstanding features of a bandsaw is the ease with which it allows you to make curved
cuts. Freehanded cuts should be made at low feed speed so that you can guide the blade along the required line. Be careful not to push the workpiece sideways off the cutting line or the blade will twist and jam in the kerf. It often pays to first cut off surplus material up to about 10 mm from the cutting line. In the case of radii which 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 will drop off and the blade cannot become jammed.
9. Cleaning and maintenance
Bearings
Apply high-quality machine grease to the bearings of the guide pulleys at regular intervals but at least after every 25-30 hours in operation.
Cleaning
Remove saw dust and chips regularly from the inside of the bandsaw. Switch off the machine and pull out the power plug before you open the housing cover. When the cover is open, clean the inside with a brush or vacuum cleaner. After every work session, remove the dust and chips from the cooling vents of the motor.
Maintenance
Do not carry out any repairs yourself. If any problems arise, take your bandsaw to a specialist workshop.
10. Ordering replacement parts
Please provide the following information on all orders for replacement parts:
- Type of machine
