SAFETY WARNINGS
WORK ENVIRONMENT
1. Keep the work area clean and well lit. Cluttered and dark areas invite
accidents.
2. Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Anyone
entering the work area must wear personal protective equipment.
Distractions can cause you to lose control and fragments of work or a
broken disc may fly away and cause injury.
4. Store power tools properly when not in use. Abrasive products should be
stored in a dry, secure place out of the reach of children.
5. Please read these instructions carefully and retain for future reference.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never modify the plug in any way.
Do not use adapter plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce the risk of electric shock.
2. Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
3. Do not abuse the power cable Never use the cable for carrying, pulling or
unplugging the power tool. Keep the cable away from heat, oil, sharp
edges or moving parts. Damaged or entangled cables increase the risk of
electric shock.
4. When operating a power tool outdoors, use an extension cable suitable for
outdoor use. Use of a cable suitable for outdoor use reduces the risk of
electric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired or
under the influence of drugs, alcohol or medication. A moment of

ASSEMBLY
PREPARATION
• Make sure that all parts are un-damaged and are present. If any parts are
missing or damaged please contact your CLARKE dealer immediately.
• For maximum stability, the bandsaw should be bolted to either a
workbench, a suitable stand, or a piece of plywood, and the plywood
then clamped firmly to a workbench using clamps, while the bandsaw is
being used.
• The saw must be located in an area large enough to allow you to work
freely, taking into account the size of your workpiece and that there is
adequate lighting.
• Make sure that the electrical supply is close by. Take extra care if extension
leads are used. Make sure that there is no possibility of tripping over the
lead when moving around the work area.
FITTING THE TABLE
1. Fit the work table to the bandsaw
using the table locking lever
components.
2. Screw the locking knob and
washer finger tight to the frame to
secure the table.

2. Use the angle scale and pointer
on the table tilting bracket to find
the desired angle.
3. Re-tighten the locking lever to
secure the table.
• For assured accuracy, we
recommend checking the tilt
angle using a protractor or set
square.
4. With the table exactly level, it
should rest on the supporting stud
shown. Adjust the height of the
stud by screwing it in or out of the
table and securing with the
locknut.
5. Check with a set square against
the blade that the table is exactly
level when resting on the stud.
TRACKING THE SAW BLADE
If the saw blade does not run in the centre of the rubber tyres, the tracking
needs to be corrected by adjusting the tilt of the upper bandsaw wheel.
1. Open the upper and lower covers
by releasing the 10mm captive
bolts.
2. Rotate the wheels by hand, taking
care of the sharp blade and
check that the blade tracks
centrally on both wheels.
3. Turn the tracking knob clockwise
or anticlockwise until the blade
tracks centrally and without
fouling on the blade guide parts including the guard.
4. When satisfied that the tracking is correct, close the covers.

mm from the sides of the blade
and closer to the rear edge than
the front as shown in the diagram.
• Slacken off the two screws using a
hex key and position each side
guide pin so that they almost touch the blade as shown below.
CAUTION: TOO MUCH TENSION CAN CAUSE THE SAW BLADE TO BREAK.
TOO LITTLE TENSION CAN CAUSE THE BLADE TO MAKE IRREGULAR CUTS

CONNECTING TO A DUST COLLECTOR
This bandsaw is fitted with a dust port
for connection to a vacuum cleaner
or dust collector such as the Clarke
CDE35 if available.
PRACTICAL OPERATION
Before commencing work, ensure the work area is clean and tidy and the
work table is clear of tools etc. Plan your work carefully and set the bandsaw
up accordingly before switching on.
• Check the blade is correctly tensioned before use (see page 12).
• Adjust the height of the upper blade guide to approx 3mm or as close as
practical to the workpiece. This provides the best safety for the operator
and giving more accurate results and greater control.
• Switch on and allow the saw blade to reach full speed before cutting.
• Use both hands to feed the workpiece. 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.
• Always use the rip fence or mitre gauge where possible to eliminate any
sideways movement of the work. This is most important when the table is
tilted at an angle.
• Remember that the blade removes material during the cut creating a gap
called the ‘kerf’, which must be allowed for, when cutting to exact sizes.
Plan your cut so that the kerf is the scrap side of the line you wish to cut.
Where necessary, allow a little more material for finishing.
• Always use a suitable holding device when cutting round or irregular
shaped timber to prevent twisting of the work piece.
TYPES OF CUT
Several types of cut are possible with this bandsaw i.e. rip cutting, cross
cutting, bevel or mitre cutting.

16
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or Servi[email protected]om
RIP CUTTING
This term refers to cutting timber in the same direction as the grain, rather than
across it. You can rip wood freehand to a drawn pencil line, but best results
are obtained by using the rip fence.
If the table is set level, set the rip-fence to the left hand side of the blade,
allowing you to use your right hand to hold the work firmly against the fence.
When cutting a bevel rip, with the table tilted at any angle up to 45o, 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 workpiece.
Long workpieces may require additional support in the form of blocks or rollers
and may be pulled as well as pushed to pass them through the bandsaw.
CROSS CUTTING
This term refers to cutting timber at right angles to the grain. This type of cut
can also be made freehand, but the mitre gauge is used to ensure accurate
results. The mitre gauge can be adjusted up to 60oto produce mitre cuts, and
with the table tilted, compound mitre cuts.
Make sure the work is held firmly against the table and against the face of the
mitre gauge. Be careful to keep your fingers away from the blade, particularly
at the end of the cut.
MITRE CUTTING
Most crosscut work, especially with small pieces is more easily controlled with
the use of a mitre gauge. The mitre gauge is also essential for accurate
compound mitre cuts. The gauge is graduated to 60ofor both left and right
hand angles.
FREEHAND CUTTING
The ease with which many different and varied shapes can be cut is one of
the most important features of the bandsaw.
When freehand cutting, always feed the work slowly so that the blade can
follow the line you wish to cut. 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. For
small curves which may be too tight for the blade, make relief cuts at 90° to
the face of the curve so that these scraps fall away as the final radius is sawn.
The blade has a minimum radius which it will be able to cut, dependant upon
its width. The blade supplied is 6.35mm wide and able to cut as little as 25mm
radius, beyond which the stress may cause it to break. If using a different
blade, a bandsaw blade radius chart should be consulted.
