6. Tighten the nut to secure the bolt in position
7. Check the table angle guide to see how far from 0 degrees the arrow
points (for your reference when cutting to angles in future)
Applications
Use the bandsaw ONLY for:
• Longitudinal and cross-cuts on timber and wood-type materials
• Curved and shaped cuts that do not excessively twist the blade
Blade selection
• The blade supplied with the bandsaw is designed for all-purpose use. When
you select a blade, pay attention to the following criteria:
• You can cut tighter radii with a narrow blade than you can with a wide blade
• Use wide blades for straight cuts. This is particularly important when cutting
wood because the blade will tend to follow the grain of the wood, with the
risk of deviating from the cutting line
• Finely toothed blades provide smoother cuts but are slower than coarse
blades
• Never use warped or lacerated blades
• For guidance on changing the blade see ‘Maintenance’
Operating Instructions
• It is recommended that hearing protection is used in addition to other safety
equipment, when operating this power tool
• Never wear gloves that are manufactured with fabric that frays. Loose
material could result in your hands being dragged into the teeth of the blade
• Ensure the Upper Cover & Lower Cover (12) are securely closed whenever
the tool is in operation
Positioning the upper blade guide
• The Upper Blade Guide (4) must be positioned as close as possible to the
workpiece to be cut. Allow a gap of approx. 2 – 3mm
• Check the setting before each cut and re-adjust as necessary
• To adjust the upper blade guide:
1. Unlock the Blade Guide Height Adjuster (24) and rotate the wheel to lower
the guide to within 2 – 3mm of the workpiece
2. Lock the blade guide height using the locking knob
Switching On/Off
• Connect the bandsaw to the electrical supply and use the On/Off Switch
(13) as follows:
• To switch the machine on, press the green button marked ‘I’
• To switch the machine off, press the red button marked ‘0’
• As a safety feature, in the event of a power cut the power switch will switch
off. When power is restored you will need to press the green button ‘I’ to
restore operation
Adjusting the fence (See Fig 11)
• The Fence (17) must always be positioned parallel to the blade for control of
the workpiece during the cut
1. Push the Fence Clip (18) up to allow the fence to be mounted on
the saw table
2. Move the fence along the table to the position required
3. Push the clip down to secure the fence in position. If the clip does not
provide sufficient hold turn it clockwise several times until it provides
sufficient grip
Making the cut
• After every adjustment it is recommended you make a trial cut to check
the new settings
• Position the Upper Blade Guide (4) as close as possible to the workpiece
(see Positioning the upper blade guide)
• Guide the workpiece with both hands, holding it by the longer side, flat on
the saw, keeping the workpiece flat on the table
• Feed the workpiece at an even speed that enables the blade to cut through
the material without difficulty and without jamming
• Use the rip fence when possible to support the workpiece
• Always aim to make a complete cut in one smooth operation rather than
stopping and starting. If you need to remove the workpiece, switch the
saw off first and wait for the blade to stop completely before freeing the
workpiece
Using the push-stick
• When handling narrow workpieces, always use the supplied push-stick.
Never place your hands close to the blade in use.
• When not in use, hang the push-stick on the hook at the back of the saw
Adjusting the blade tracking
CAUTION: The blade must be correctly tensioned before making any
adjustment
1. Unfasten the Upper and Lower Cover Locks (14 & 11) with the supplied
screwdriver and open the Covers (12)
2. Slowly turn the Upper Blade Wheel (2) clockwise by hand. The blade
should run in the middle of the wheel; if this is not the case, you must
adjust the angle of the wheel:
a. If the blade tends to run to the back edge of the wheel, i.e. towards
the machine frame, turn the Blade Tracking Adjustment Knob (15)
anticlockwise until, as you turn the wheel, the blade runs in the centre.
b. If the blade tends to run to the front edge of the wheel, turn the setting
screw clockwise
3. After setting the upper blade wheel, check that the blade is running
centrally in the lower blade wheel. If not, continue to adjust the angle of
the upper blade wheel until the blade runs centrally in both wheels
4. Once the blade is correctly adjusted, close and re-fasten both covers
NOTE: Whenever you adjust the blade tension or tracking, you must re-set
the support bearings and guide pins in the upper and lower assemblies.
Adjusting the upper support bearing (See Fig 7)
1. Loosen the Upper Support Bearing Hex Screw (26)
2. Position the Upper Support Bearing (27) so that it is just behind the blade,
but not in contact with the blade. Allow a gap of 0.5mm max
3. Re-tighten the fixing screw to secure the bearing in position
NOTE: The Upper & Lower Support Bearings (27 & 34) support the blade only
when cutting. Otherwise the blade should not be in contact with the support
bearings
Adjusting the upper guide pins (See Fig 8)
1. Use the hex key to loosen the hex screw for the Upper Guide Pins
Housing (30)
2. Adjust the position of the housing so that the front edge of the guide pins
is approx. 1mm behind the gullet of the blade teeth. This prevents the
guide pins from damaging the teeth and allows them to guide the blade
on the flat surface behind the teeth
3. Make sure the guide pins are parallel with the blade
4. Tighten the hex screw to secure the housing in position
5. Now loosen the Hex Screws for the Upper Guide Pins (29)
6. Adjust the position of the Upper Guide Pins (28) so that there is a gap of
approx. 0.5mm between the guide pins and the blade on both sides
7. Tighten the hex screws to secure the pins in position
8. Turn the Upper Blade Wheel (2) several rotations in a clockwise direction
to check that the pins do not touch the blade. Adjust the position of the
pins if necessary
IMPORTANT: The blade will be damaged and rendered useless if the teeth
come into contact with the pins during operation
To access the lower assembly support bearing and guide pins
1. Remove the Saw Table (6) (See ‘Installing the saw table’) to access
the lower guide pin assembly
2. Unlock the Lower Cover Lock (11) using the supplied screwdriver and
open the bottom cover
3. Remove Lower Blade Guard (32) to allow access to the Lower support
bearing (34)
Adjusting the lower support bearing (See Fig 9)
1. Adjust the Lower Support Bearing (34) using the same method as for the
upper support bearing using the same 0.5mm maximum gap
Adjusting the lower guide pins
1. Adjust the position of the lower guide pins using the same method as for
the upper guide pins
2. Use the same 0.5mm gap from the blade with the pins aligned slightly
behind the teeth by 1mm to protect the teeth of the blade
3. Check that the lower guide pins do not come into contact with the blade
by turning the Lower Blade Wheel (9) clockwise several rotations. Re-
adjust the position of the pins if they come into contact with the blade
4. Once adjustment is completed refit the parts you have removed
Checking alignment of the saw table (See Fig 10)
1. Raise the Upper Blade Guide (4) as far as it will go
2. Loosen the Table Lock Handles (21) so that the table can pivot
3. Using a set square (not supplied), position the table at exactly 90° to
the blade
4. Tighten the table lock handles to secure the table in position
5. Loosen the Table Alignment Securing Nut (37) on the Table Alignment Bolt
(36) and rotate the bolt until the head of the table alignment bolt is in
contact with the table. (See Fig 10)
