CONNECTING YOUR MACHINE TO THE POWER SUPPLY: (230V ONLY)
To eliminate the possibility of an electric shock your machine has been fitted with a BS approved, non rewirable moulded plug and cable which incorporates a fuse, the value of which is indicated on the pin face of the plug. Should the fuse need to be replaced an approved BS1362 fuse must be used of the same rating, marked thus . The fuse cover is detachable, never use the plug with the cover omitted. If a replacement fuse cover is required,ensure it is of the same colour as that visible on the pin face of the plug (i.e. red). Fuse covers are available from your Draper Tools stockist. If the fitted plug is not suitable, it should be cut off and destroyed. *The end of the cable should now be suitably prepared and the correct type of plug fitted. See below.
*WARNING:
A plug with bare flexible wires exposed is hazardous if engaged in a live power socket outlet.
WARNING:THIS APPLIANCE MUST BE EARTHED.
Green and Yellow - Earth, Blue - Neutral, Brown - Live. As these colours may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows.: The wire which is coloured green and yellow must be connected to the terminal in the plug which is marked with the letter 'E' or by the earth symbol or coloured green or green and yellow. The wire which is coloured blue must be connected to the terminal which is marked with the letter 'N' or coloured black or blue. The wire which is coloured brown must be connected to the terminal which is marked with the letter 'L' or coloured red or brown. N.B.Three phase machines must be connected by a qualified electrician.
EXTENSION LEAD CHART: Extension lead sizes shown assure a voltage drop of not more than 5% at rated load of tool.

ADDITIONAL SAFETY RULES FOR BANDSAWS
1. Lower the blade guard to within approximately 3mm (
1
8") above the material being cut.
2. Always keep hands and fingers away from the saw blade,especially when coming to the end of a cut.
3. Use a push stick or piece of scrap wood to do the pushing and guiding when sawing small pieces which require the fingers to be close to the saw.
4. Switch the machine off and let the blade come to a stop before removing scrap pieces from the table.
6. Make all adjustments and set ups with the power off and plug removed from the power supply, such as tilting the table, adjusting the saw blade guards and blade guides.

line up with the zero mark on the tilt scale.
ADJUSTING THE BLADE GUIDES AND BACK UP BEARING
NOTE: The upper and lower blade guides and back up bearings support the bandsaw blade during cutting operations.The guides and bearings should be checked and adjusted whenever a different blade is fitted.
1. The upper back up bearing ✾✌ Fig.29. should be
adjusted first. Loosen the hexagon set screw ✿✌ located to the side of the bearing.
2. Adjust the back up bearing to within 1.5mm (
1
32") of the blade and tighten the hexagon set screw. Now repeat this exercise for the lower blade guide assembly.
NOTE: The back up bearing supports the back edge of the blade during a cutting operation.The blade should NOT be in contact with the bearings when you stop cutting.
3. Next adjust the position of the upper blade guide
support ❀✌ Fig.30. Loosen set screw ❁✌ and slide the blade guide support along until the front edge of the blade guides are 1.5mm (
1
32") behind the gullet of the blade.Tighten the set screw.
4. Repeat this exercise for the lower blade guide. IMPORTANT: The blade will be damaged if the
blade teeth hit the blade guides whilst the bandsaw is operating.Correct adjustment of the upper and lower blade guards will prevent this from happening.
Loosen the two hexagon screws ❂✌ Fig. 31. that lock the upper blade guides ❃✌ and press both guides gently against the sides of the blade. Do not pinch the blade. Release the guides and rotate the upper wheel slightly clockwise (moving the blade downwards towards the table).
Check that one guide is not further away from the blade than the other and tighten the hexagon screws ❂✌. Repeat this exercise for the lower blade guides.

USE OF ACCESSORIES
MITRE GUIDE
Most cross cut work, especially with small pieces of material are more easily controlled with the use of the mitre guide.The mitre guide is also used for accurate mitre and compound cuts.The guide is graduated to 45˚ for assistance in cutting both left and right hand angles. Fig.32.
RIP FENCE
True straight line rip cutting is best done by guiding the work against the rip fence.The fence can also be used for cutting off exact widths. Fig.33.
WARNING: The supporting surface where the band saw is mounted, should be examined carefully after mounting to ensure that there is no movement during use. If any tipping or walking is noted, secure the workbench or supporting surface before operating bandsaw.
MOUNTING BANDSAW TO WORKBENCH
If the bandsaw is to be used in a permanent location, it should be fastened securely to a firm supporting surface such as a workbench.
If mounting to a workbench,holes should be drilled through the supporting surface of the workbench using dimensions illustrated. Fig.34.
1.Each leg should be bolted down securely using
10mm diameter machine bolts, lockwashers and 10mm hex. nuts (not included). Bolt length should be 45mm plus the thickness of the bench top.
2.Locate and mark the holes where the bandsaw is to
be mounted.
3.Drill four 12mm diameter holes through the
workbench.
4.Place the bandsaw on the workbench aligning the
holes in the feet with the holes drilled in the workbench.
5.Insert all four 10mm bolts and tighten.
NOTE: All bolts should be inserted from the top. Install the washers and nuts from the underside of the bench.
CLAMPING BANDSAW TO WORKBENCH
The bandsaw can be clamped to a workbench using two (2) or more "C" clamps on base of unit.Fig.35.

TIPS ON USING YOUR BANDSAW
For all cutting operations the upper blade guard should be adjusted to just clear the work being cut (approx. 3mm or
1
8"). Not only does this provide the best operator safety, but it also brings the blade guides closer to the work giving more accurate results and easier control.
Use both hands to feed the workpiece into the blade.The work must be held flat on the table at all times to prevent binding of the blade. Use a steady even pressure just sufficient to keep the blade cutting at full speed.
Always use a rip fence or mitre guide where possible to eliminate any sideways slip of the work.This is most important when the table is tilted to an angle.
Always plan work ahead. The tradesmans’ rule is “measure twice, cut once”. It is best to finish a cut in one continuous operation, but frequently backtracking will be necessary. Turn off the motor and allow the blade to come to a complete stop before backing the blade out of the cut.
Remember that the blade removes material during the cut. This gap created by the blade is called the kerf and must be allowed for when cutting to exact sizes. Plan your cut so that the kerf is to the scrap side of the line you wish to cut. If necessary, allow a little more for finish sanding.
RIP SAWING
This term refers to the cutting of timber with the grain rather than at a right angle to the grain.You can rip wood freehand to a previously drawn line,but best results are obtained by using the rip fence. If the table is level, set the rip fence to the left hand side of the blade.This allows you to use your right hand to hold the work firmly against the fence. The width of cut indicator on the front of the worktable shows the distance between the blade and the right hand edge of the timber.
When cutting a bevel rip, with the table tilted at any angle up to 45˚, set the rip fence to the right hand side of the blade if the width of the workpiece allows it.
With the fence on the downhill side of the table it will help support the work against slip.The width of cut indicator shows the distance between the blade and the rip fence at the table surface.
CROSS CUTTING
This term refers to the cutting of timber at right angles to the grain. This type of cut can also be made freehand but the mitre guide is used to ensure accurate results. The mitre guide can be adjusted to a 45˚ angle to assist during mitre cuts, and with compound mitre cuts.
Make sure the work is held firmly against the table and against the face of the mitre guide. Be careful to keep your fingers away from the blade, particularly at the end of the cut.
FREEHAND SAWING
The ease with which many different and varied shapes can be cut is one of the most important features of the bandsaw. Select a blade suitable for cutting the smallest radius in the work you have planned.
When freehand cutting always feed the work slowly so that the blade can follow the line you wish to saw. Make sure not to drag the work off line forcing the blade sideways,or twisting it.
In many cases, it is helpful to rough cut about 6mm away from the line in difficult curves and corners. In the case of very sharp curves which may be too tight for the blade, make relief cuts onto the face of the curve so that these scraps will fall as the final radius is sawn.

MAINTENANCE
CHANGING TYRES
Eventually the rubber tyres on the bandsaw wheels will wear due to the constant contact of the sharp teeth of the blade. Remove the blade, lift the edge of the tyre with a small screwdriver and the tyre can be worked off the wheel easily. We recommend that the two tyres be changed at the same time. (See Spare Parts Listing/Drawing). Refit blade
BLADE GUIDES
Blade guides should be inspected regularly for wear or chipping.When replacing guides replace all guides at the same time,both upper and lower. (See Spare Parts Listing/Drawing).
BEARINGS
All bearings used in the construction of your bandsaw and its motor are sealed and lubricated for life.
CLEAN OUT
Accumulated dust and chips should be removed from inside the bandsaw frequently. Remove the front cover and use a brush or vacuum cleaner. At the end of every work session clean sawdust away from the motor vents.
BLADE BRUSH
Ensure that you check on a regular basis that the brush is in full contact with the bandsaw blade and wheel.This will help to keep the tyres on the wheel clean and assist with the quick and smooth run down of the bandsaw blade.
NOTE: Bandsaw blade should stop within 10 seconds of the machine being switched off as per original set up.
