it comes to a complete stop.
17. Do not use any power tools while under the effects of drugs, alcohol or medication.

18. Always wear a face or dust mask if operation creates a lot of dust and/or chips. Always operate the
tool in a well ventilated area and provide for proper dust removal. Use a suitable dust extractor.
ADDITIONAL RULES FOR BAND SAWS
1. Ensure that the saw table is clear of off-cuts, tools or anything else that might foul the work-piece.
2. When cutting long boards use one or more roller stand(s) to support the work or have a competent
helper to support it as it feeds off the rear of the table.
3. Always make sure that the blade is tracked and tensioned correctly before starting to use the saw.
4. Always use a brush to clear the table of dust or debris. NEVER use your hands, especially when
the machine is running.
5. Always ensure that the thrust bearings and guide blocks are correctly adjusted before using the
saw.
6. ALWAYS USE A PUSH STICK WHEN IT IS NECESSARY TO PUSH ANY PIECE OF MATERIAL
OF SUCH SIZE THAT IT WOULD BRING YOUR HANDS WITHIN 30 CM OF THE BLADE.
7. Do not cut material that is badly warped or which has screws or nails in it.
8. Be extra vigilant when cutting stock which has loose knots in it as these my fly out of the saw.
9. NEVER tilt the table when the saw is running.
10. To avoid exposure to hazardous dust, do not use this saw without connecting it to a suitable dust
extractor.
11. Always work with a sharp saw blade and feed the work at a rate suited to the thickness and
hardness of the material.
Note: This band saw has been designed and built solely as a woodworking machine. Do not modify it in
any way or use it for anything other than its designated purpose. Neither the manufacturers nor the
supplier are liable for any damage or injury caused by incorrect assembly, operation or electrical
connection of this machine.

Unpacking
The bandsaw is supplied in one carton
After cutting the tape at the top of the
box, invert it on a table or bench and lift
it off the polystyrene insert. Separate
the two pieces of packing and remove all
the components.

Assembly
Place the saw, so that it is lying on its
back.
Prop the upper end up on a suitable
block or box, so that the table may be
held in place with the four threaded
holes in line with the holes in the upper
trunnion.
Using the four bolts and serrated
washers supplied, attach the table to
trunnion, leaving the bolts slightly loose.
Carefully place a steel rule against the
side of the blade, between teeth.
Twist the table on the trunnion until the
rule is aligned with the slot.
Tighten the four bolts holding the table
to the trunnion.

Check to see if the blade is centred in
the slot. You will probably find that it is
offset to one side or the other.
The gap in the insert allows for 45°
cutting.
The lower trunnion is attached to the
body of the saw by three hex headed
bolts.
These may be slackened and the
trunnion slid in either direction until the
blade is centred.
After adjustment, tighten them securely.
Adjustable pointer.
This lever locks and unlocks the
trunnion so that the table may be tilted.

Having set the table so that the blade is
centred, use a set square position the
table at right angles to the blade.
Lock it in position and if necessary,
adjust the pointer so that it aligns with
the zero as shown above.
Tilt the table to 45°
Insert the table stop screw, complete
with locking nut, into the tapped hole on
the top face of the saw’s lower housing.
Reset the table to 0° and adjust the
screw so that it touches the underside of
the table.
Secure it in this position with the
locknut.
Attach the Rip Fence Carrier to the front
edge of the table using the four M8 x
12mm bolts provided.
Screw in and lock the push stick hanger
on the side of the frame.
This completes the assembly of your
saw.

Setting Up The Bandsaw
Blade tensioner
Blade guard height adjuster and lock
Tracking control and lock

Set The Blade Tension
Turn the blade tensioner clockwise to
increase the tension. Turn the knob
anticlockwise to lower the tension.
Raise the blade guard to its highest position
and increase the tension until it is only
possible to deflect the blade sideways by 2
to 3 mm at its midpoint between the table
and the guard.
Set The Blade Tracking
When fitting a new blade it may be
necessary to adjust the tracking (the
alignment of the top wheel).
The blade should sit on the centre or to the
front of the rubber tyre on the wheels.
To check the tracking, open both doors and
rotate the top wheel by hand.
If the blade starts to move towards the front
edge of the wheel, turn the tracking control
(located at the rear) clockwise.
Lock the tracking control in this position.
Set The Upper Blade Guides
The upper and lower thrust bearings
and blade guide pins should be set up
next.
Thrust bearing
Guide pin
Guide pin locking screw
The thrust bearing should be about
0.5 mm behind the back of the blade.
Adjust it and lock in place.
Slacken the guide pin locking screws
then adjust the pins so that there is a
clearance of 0.5mm either side of the
blade. Lock the pins in place with the
grub screws.

Set The Lower Blade Guides
The lower thrust bearing is adjusted
similarly.
Lower thrust bearing
Locking screw
The thrust bearing should be about
0.5 mm behind the back of the blade.
Adjust it and lock in place.
Slacken the guide pin locking screws
then adjust the pins so that there is a
clearance of 0.5mm either side of the
blade. Lock the pins in place with the
grub screws.
Locking screws

Making A Cut
For every type of of cut, the blade guard should be lowered so that the bottom edge of the guide
is just above the work piece. This is for safety and to better control the blade during the cut.
Always use a push stick so that you keep your fingers at least 30cm from the blade.
Straight Rip Cuts
Ripping cuts are generally made using
the guide fence and run along the grain
of the timber.
The rip fence may be used on either
side of the blade.
Rip Fence
Crosscutting
Cutting across the grain is generally
done using the mitre fence.
The rip fence may be used as a length
stop for repetitive cross or mitre cuts.
Mitre Fence
Blade width Min. Diameter
6mm (1/4”) 60mm (2.1/2”)
10mm (3/8”) 100mm (4”)
Cutting Curves
The bandsaw can be used to cut curves
freehand. The diameter of the curve you
can cut depends on the width of the
blade. A narrower blade can cut tighter
curves than a wide blade. The table on
the left gives a guide.
Note: Once you have cut curves with a
blade, the set of the teeth will have
changed. After having cut curves with a
blade it will not cut so accurately in a
straight line. Ideally you should keep
one blade for straight cuts and one
blade for curved cuts.
Your bandsaw is now ready for use.
It is recommended it be bolted to a bench and a suitable dust extractor be attached.

Changing The Saw Blade
Take care as the blade teeth are sharp.
Wear protective gloves if necessary.
Unplug the power supply.
Remove the rip fence guide rail by
loosening the fixing bolts underneath
the table.
Open both doors and reduce the blade
tension by turning the tension knob
anticlockwise.
Lower the blade guard fully down.
Slide the blade off the wheels and ease
it out through the slots in the left hand
column, the blade guard and the table.
Reverse these steps to fit the new
blade. Ensure that the teeth are at the
front and pointing down.
If the new blade is a different width,
tension & track the blade first, then
adjust the guide pins and thrust
bearings as shown in this manual.
