ADDITIONAL SAFETY RULES FOR
ELECTRICAL INSTALLATION
BANDSAWS
•Set the blade guide block assembly as close
as possible to the workpiece.
•Switch off the saw, and make sure the blade
has come to a complete stop before clearing
sawdust or off-cuts from the table.
•Keep the saw properly adjusted, paying
particular attention to the blade tension and
tracking, and position of the blade guides.
•Disconnect the saw from the mains supply
before removing the wheel cover.
•Make sure there are no nails or foreign objects
in the part of the workpiece to be sawn.
•Be extra cautious with very large or small, or
irregularly shaped workpieces.
•Set up the machine and make all adjustments
with the power OFF.
•NEVER operate the machine with the wheel
cover or blade guards off. They must all be in
place and securely fastened when
performing any operation.
•When cutting large or oversize stock, always
ensure the material is supported at table
height.
•Any adjustable component must be securely
locked in position to ensure it cannot vibrate
free during operation.
•When sawing curves, make relief cuts to allow
removal of scrap material. This will prevent
undue twisting or binding of the saw blade.
Make the relief cuts before starting a curved
cut.
•When sawing, hold material firmly, and feed
into blade at a moderate speed.
•DO NOT saw any material that does not have
a flat surface on which to bear, unless a
suitable support is used. Round or tubular work
has a tendency to roll, and causes the blade
to ‘bite’....always use a suitable device to
hold round material securely.
•Ensure the bandsaw is securely fixed in
position before operating.
•When cutting with the table tilted...ensure the
parallel fence is mounted to the right of the
saw blade.
•Never cut workpieces that cannot be held
comfortably and securely by hand.
•ALWAYS wear Safety Goggles and Ear
Defenders. We also strongly recommend the
use of a breathing mask.
•ALWAYS rPeplace Table Insert if damaged.
Connect the mains lead to a standard, 230 Volt
(50Hz) electrical supply through an approved 13
amp BS 1363 plug, or a suitably fused isolator
switch.

ASSEMBLY
PREPARATION FOR USE
GENERAL NOTES:
For maximum stability and safety, the Bandsaw should
be bolted firmly to either a workbench, a suitable
stand, or a piece of plywood, 5/8” thick, and the
plywood should be clamped firmly to a workbench,
using ‘G’ clamps, whenever the bandsaw is being
used.
Ensure the saw is located in an area large enough to
allow you to work freely, taking into account the size
of workpiece, and that there should be adequate light.
Never work in your own shadow.
Ensure also that an adequate electrical supply is close
at hand. Take extra care where extension leads are
used...ensure there is no possibility of tripping over the
lead when moving around the work area.
Any protective coating on the Band Saw should
be removed using a cloth moistened with
paraffin.
DO NOT use acetone, petrol or paint thinners.
The saw is fully assembled, except for attaching
the table as follows:
All adjustments are factory set, except for those
detailed below which MUST AL W AYS be checked
before switching on the saw.
A. Blade Tension
Blade tension is effected by raising or lowering
the upper wheel, by means of the Blade Tension
Adjuster Knob (A, fig. 1) The upper wheel is
mounted on a spring loaded trunnion, and
tension is therefore a matter of ‘feel’.
Turn the knob clockwise until it becomes tight.
The blade should be taught enough to prevent
slippage, but not overtight, as this will lead to
breakage of the blade.
Additionally, the upper wheel can be adjusted
so that the blade will run centrally about both
wheels. This adjustment is factory set and should
not need to be carried out. If, subsequently, the
blade persists in running off the wheels or runs
off-line, then the adjustment necessary to
overcome this is detailed under ‘Maintenance’.
1. Remove the clamping screw from the table
slot, (E, Fig. 1), and the table insert from the
table, (K, Fig.1).
2. T aking care not to damage the saw blade or
the table, carefully manoeuvre the table, with
the saw blade in the table slot, on to its
mounting.
3. Remove the handle
from the table clamping screw by
unscrewing spring loaded screw
arrowed in illustration.
Fig. 2
4. Hold the table firmly so that the
quadrant, on the
underside of the
Fig. 3
table, is flat against
the body of the
saw, with the
curved guide (on
the body of the
saw), engaged in its
slot in the quadrant.
Screw in the
clamping screw as
far as it will go, by hand as shown in Fig. 3.
5. Replace the handle on the clamping
screw ensuring the spring is in place.
6. Replace and tighten the clamping screw in
the slot in the table then replace the Table
Insert.
The parallel fence and mitre gauge may now
be placed on the table.
B. The Table Angle
For all normal sawing operations, it is important
to ensure that the table is set at 90O to the blade.
This is checked by sliding an engineers square
on the table, up to the blade (with the blade
correctly tensioned), and carrying out a visual
inspection.
If necessary slacken off the Table Clamping
Screw, and move the table until you are satisfied
it is square with the blade, then re-tighten the
Clamping Screw.
It may also be necessary
to undo the Table Stop
Screw lock nut (see
Fig.4), and screw the
Stop Screw in or out so
that it just contacts the
body of the machine,
when the table is at 90
to the blade. Nip up the
lock nut when satisfied.
Now, whenever the
table is set to cut Mitres, it is a simple procedure
to reset the table to 90º. i.e. when the stop screw
touches the body, the table is at 90º.
With the Table Clamping Screw tight, check to
ensure the pointer beneath the table, is correctly
set to zero on the scale on the quadrant. If
necessary, slacken the pointer securing screw,
and reset the pointer to zero.
7
O
Fig. 4
Page 8
C. Blade Guide Height
DUST EXTRACTION
The Upper Blade Guide must be adjusted
according to the thickness of the workpiece to
be cut.
Slacken off the Guide Block using knob (L, Fig. 1)
and adjust the height of the guide so that it is nomore that 5mm higher than the workpiece, then
secure in this position.
Check this setting and readjust if necessary
before each cut.
OPERATION
Check to ensure that all safety precautions have
been complied with before switching on the
mains supply and pressing the ON button (1).
Allow the blade to come to full speed.
Ensure the workpiece is held firmly against the
table at all times. (See ‘Tips On Using Your
Bandsaw’ which follows).
Remember that round stock should be clamped
as shown in Fig. 5, to ensure it cannot roll.
Always feed the workpiece at a rate that allows
the blade to cut without difficulty.
Whenever new adjustments are made, you
should always make a trial cut in order to check
the settings.
Parallel Fence and Mitre Gauge
Always use the parallel fence or mitre gauge on
all cuts for which they are intended, to prevent
the blade from running off the cutting guide line,
particularly when working with a tilted table.
When using the parallel fence, there must be
sufficient clearance between the blade and
fence so as to allow the operator to hold the
workpiece firmly, between fence and blade,
without endangering the hand. The other hand
is used as a guide/support ONLY, the hand
between fence and blade being the hand that
feeds the workpiece into the blade.
If the clearance is small, then a push stick should
be used; i.e the workpiece is fed into the blade
with a pushstick.
NOTE:
Pushsticks can easily be made using a piece of wood
1/2”x1” x 12” , with a 1/4” notch cut in one end, as
shown below.
A dust extraction outlet is provided which may
be connected to a vacuum cleaner or a dust
extraction device, such as the CLARKE CDE35,
when the need arises.
Please see your CLARKE dealer for details.
TIPS ON USING YOUR BANDSAW
It should be understood that this machine is
primarily designed for freehand cutting - i.e. to
cut shapes in relatively thin wood. It is NOT
designed for cutting plastics, or any other
material. However, to increase its versatility, it is
possible to cut straight lines using either the Mitre
Gauge or Parallel Fence, as described below.
For all cutting operations, the upper guide block
and blade guard assembly should be adjusted
to be just clear of the work being cut. Not only
does this provide the best safety for the operator,
but it also brings the blade guides closer to the
work giving more accurate results and better
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.
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 your work ahead, and aim to make
a complete cut in one pass, rather than stopping
a cut, which requires the workpiece to be
withdrawn. The tradesmans’ rule is “measure
twice, cut once”. It is best to finish a cut in one
continuous operation, but frequent backtracking
may be necessary.
If you do have to withdraw the workpiece, switch
off the bandsaw first, by pressing the OFF (O)
button, and allow the blade to come to a
complete stop before backing it 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 the scrap
side of the lines you wish to cut. If
necessary, allow a little more for
finish sanding.

RIP SAWING
This term refers to the cutting of the timber with
the grain, rather than at a right angles 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 set at a level angle, set the rip fence
to the left hand side of the blade for long pieces,
allowing you to use your right hand to support
the work and your left hand, or pushstick to feed
the work into the blade and held firmly against
the fence.
For shorter pieces you may set it to the right as
shown in fig. 7, using your right hand to hold the
work firmly to the table and rip fence.
Fig. 8 shows a similar operation with the table set
to produce a 45º bevel.
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 to a angles up to 45°, to produce mitre
cuts, or with the table tilted as well - 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.
Slide the Gauge and workpiece together , across
the table with the guide bar engaged in the slot
provided as shown in Fig. 9.
Fig. 7
Fig. 8
NOTE:
In each of the illustrations, for clarity, the left hand has
been omitted, however, in practice it would be used
to support and guide the workpiece, on the opposite
side of the blade, wherever possible.
FREEHAND SAWING
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 difficult curves
which may be too tight for the blade, make relief
cuts at 90° to the face of the curve so that these
scraps will fall away as the final radius is sawn.

MAINTENANCE
5. Open the Wheel Cover using a screwdriver
on each of the two knob centre screws
ALWAYS disconnnect from the power supply
before carrying out any maintenance
After use
1. Accumulated dust and chips should be
removed from inside the bandsaw. Open the
Wheel Cover and use a brush or vacuum
cleaner at the end of every work session.
2. ALWAYS Lower the Blade Guide Block and
Guard Assembly to its lowest position and lock
it in place.
3. ALWAYS slacken off blade tension.
Periodically
1. Apply a coat of wax paste to the table surface
which will allow the wood stock to glide across
it smoothly and effortlessly.
2. Inspect electric cables to ensure they are not
cracked or damaged in any way. Damaged
cables should be renewed immediately.
3. Inspect the blade for damaged teeth. If any
are broken, the blade should be renewed.
BLADE RENEWAL
1. Disconnect the mains cable from the supply.
2. Slacken off blade tension fully, using the
adjuster knob on top of the machine.
3. Remove both halves of the Upper Blade
Guard by removing the screws at B, Fig. 10 ,
sufficient for the left half of the guard may be
removed, and slackening off screws A, fig 10,
so that the right half may be removed.
4. Remove the Table Insert and the Clamping
Screw, within the table slot, then remove the
table.
Fig.10
6. Ease the blade off the upper and lower
wheels, taking care that the blade does not
‘spring’ as this could cause serious injury. It is
advisable to wear proper clothing, i.e.
industrial gloves, long sleeves and goggles.
7. Refer to Figs. 12 and 13, and using the Hex.
wrench provided, slacken off the screws ‘A’
and ‘G’. This frees the two Blade Support
Bearings, the upper one of which is shown at
‘E’.
Move the bearing ‘E’, and the Lower Guide
Block (H), backwards as far as possible.
8. Slacken off the screws shown at ‘B’ and ‘D’.
This frees the Blade Guides shown at ‘C1 and
C2’....move them away from each other to
provide a gap..
9. Replace the new blade - over the lower
wheel first.
NOTE: It may be necessary to slacken of the brush
mountings in the lower left corner of the wheel housing
in order to manoeuvre the blade between brush and
wheel rim.
Ease the blade over the upper wheel and
through the Blade Guide Block assemblies,
ensuring the teeth point down towards the
table.
10. Try as far as possible to align the blade so that
it runs as near central on the wheels as
possible, then apply tension by turning the
Blade Tension Adjuster Knob clockwise until
the blade feels firm on its run between the
two wheels, but do not overtighten.
11. Readjust the brush if previously moved, or if
not, check to ensure it is brushing firmly up
against the wheel.
NOTE: The brush is responsible for bringing the wheels,
and hence the blade, to a quick stop when the
machine is switched off.
NOTE: Removal of the upper blade guards and table
not only simplifies the blade removal process but also
gives easy access to the various components which
will subsequently require adjusting.
12. Carry out all adjustments, i.e. Blade tracking
and Blade Guide Bearings, as follows:
A. Blade Tracking
Fig. 11
It is important that the
blade runs centrally
about the upper and
lower wheels. Note that
the upper wheel carries
a rubber tyre which has
a convex outer surface.
It is important therefore
to ensure the blade runs
10
Page 11
Fig. 12Fig. 13
exactly in the centre of the tyre. This adjustment
is effected by turning the Tracking Adjuster Knob
(J, Fig. 11).
Screwing ‘in’ (clockwise), will cause the upper
wheel to tilt inwards at the top slightly, which in
turn causes the blade to run on the front of the
wheel. Screwing anticlockwise, has the opposite
effect.
The sequence of adjustment is as follows:
Ref: Fig’s. 12 and 13
1. Apply tension to the blade by screwing the
tension adjuster knob clockwise until the blade
feels firm on its’ run between the two wheels.
2. Turn the upper wheel clockwise, by hand, and
observe the reaction of the blade, and its
position on the tyre of the upper wheel
3. If the blade begins to move towards the front
edge of the tyre, (i.e. towards you as you look
at it), slowly turn the adjuster knob anticlockwise, causing the upper wheel to tilt
outwards at the top, thereby causing the
blade to move further towards the back edge
of the tyre. Conversely, if the blade tends to
run towards the back edge of the tyre, turn
the alignment knob clockwise.
Tracking is correct when the blade runs
precisely in the middle of the wheel.
Fig. 14
IMPORTANT:
It is essential that this
adjustment is carried out
correctly, as it has a direct
bearing on the ability of
the saw to cut in a straight
line.
NOTE:
Should you have difficulty in moving the tension
adjuster, it is possible that the Guide Screw, (arrowed
in fig 14) is too tight. Slacken it off slightly using the
Hex. wrench supplied, to free off the mechanism. Do
not leave this screw too loose, it should be firm, but
the trunnion must be free to move up and down.
When tracking is correct, it is necessary to adjust
the Blade Guides as follows:
B. Blade Guide Adjustments.
(Ref Figs 12 & 13)
NOTE:
a. Blade Guides should be inspected regularly for
wear or chipping. When replacing guides replace
all guides at the same time, both upper and lower.
b. In order to obtain satisfactory results, it is important
that the Blade Guide adjustments are properly
maintained at all times. Before carrying out these
adjustments, the blade must be correctly
tensioned, and tracking properly.
1. Upper Blade Guides
The Guide Block (K), carries the Blade Guides
(C1) and the Blade Support Bearing (E).
The Blade Guides provide side support for the
blade, and are adjusted as follows:
1.1 Lower the Upper Guide Block to its lowest
position and secure it.
Check the position of the Blade Guides. They
should be positioned so that they run in the
middle of the flat portion of the blade and
must NOT come into contact with the teeth
(see Fig.15).
Slacken off the screw (F), if necessary, using
the Hex. wrench provided. This allows the
guide housing to move in or out as required
11
Page 12
Fig. 15
until the guides (C1) are positioned correctly.
When correctly aligned, re-tighten screw (F).
1.2 Slacken off the two screws (B), securing the
Blade Guides (C1), and position each guide
in turn so that it lightly touches the side of the
blade. Secure firmly in this position by retightening the screws (B).
Simultaneously, slide the bearing to within 1/32”
(0.4mm)of the back of the blade (shown in
fig.16).
Re-tighten screw (A) using the Hex. wrench
provided when completely satisfied.
2. Lower Blade Guides
Ref: Fig.18
The manner of adjustment is similar to that for the
upper blade guides....however, it is necessary to
check the position of the Blade Support Bearing FIRST .
The sequence of adjustment is as follows:
2.1 Slacken the lower blade guide securing
screws (D) (if not already loose).
Turn the upper wheel to ensure the blade is
not pinched or that it is not being pushed to
one side by a maladjusted guide. If necessary,
repeat the process until completely satisfied.
With the Guides correctly set, it is now necessary
to adjust the Upper Blade Support Bearing (E).
The Blade Support Bearing, prevents the blade
from being pushed backwards, and protects it
from tooth damage.
This bearing is adjusted as follows:
(Ref Figs 16)
1.3 With screw ‘A’ , (which secures the shaft
carrying The Blade Support Bearing ‘E’),
slackened, turn the shaft, using a screwdriver
in slot M, so that the blade runs on the edge
of the bearing as shown in fig. 17
NOTE: The bearing is mounted on a cam so turning
the shaft will move the bearing, across the blade.
Fig. 16
Fig. 17
Fig. 18
2.2 Slacken the two Lower Guide Block mounting
screws (G) and position the Guide Block ‘H’
so that the correct clearance of 1/32”
(0.4mm), is achieved between the rim of the
bearing and back of the blade. Re-tighten
the mounting screws (G).
2.3 Adjust the Blade Guides (C2) so that they
lightly touch the side of the blade. Secure
firmly in this position by re-tightening the
screws (D).
2.4 Turn the upper wheel to ensure the blade is
not pinched or that it is not being pushed to
one side by a maladjusted guide. If necessary,
repeat the process until completely satisfied.
2.5 With the upper and lower guides fully
adjusted, the Upper Blade Guard may be refitted, the Wheel Cover closed, using a
screwdriver on the cover knob centre screws,
and the Table r eassembled and replacing the
clamping screw and Table Insert.
2.6 OBSERVING ALL PRECAUTIONS, plug the
machine in to the supply and switch on.
Check for any unusual noises. A harshness in
sound suggests that one or more of the blade
guides is interfering with the blade. This should
be investigated and rectified before use.
