Read these safety instructions in conjunction with the
Replacing the Saw Blade: (Ref: Fig.4)
The saw blade is not easy to sharpen, and we recommend fitting a replacement when the blade becomes blunt, loses its set, or becomes bent or cracked. Replacement blades are available from your local dealer or Clarke International Spare Parts Department.
1. Remove the table by first removing the table set screw then fully unscrewing the securing knobs.
2. Back off all blade guides and blade supports as detailed under ‘Blade Guide Adjustments’ on page 10.
3. Remove the front cover to gain access to the blade.
4. Turn the blade tension locking knob (25) one complete turn anticlockwise.
5. Turn the blade tension Hex. socket head adjuster screw (24) fully anticlockwise to relieve all tension from the blade.
5. Carefully pull the blade from the wheels taking great care not to damage your hands on the teeth. It is recommended that a pair of industrial gloves be worn for this task.
6. Position the new blade over the wheels, feeding it through the blade guides, ensuring that the teeth point downwards toward the table. Position it as close to the centre of each wheel as possible.
7. Turn the blade tension locking knob clockwise and correctly tension the blade.
8. Carry out tracking checks and adjust if necessary.
9. Readjust all blade guides and blade supports as detailed under ‘Blade Guide Adjustment’ on page 10.
10. Replace the table and the front cover.
11. Plug the machine into the mains supply and with a slow speed selection, push the ON (I) button. Gradually build up the speed and allow to run for 10 - 15 minutes at a moderate speed in order to settle the blade. (Essential when running the blade for the first time).
Before use, check blade tension and adjust if required.
NOTE: It is strongly advised that for the first few cuts, the cutting pressure exerted on the workpiece should be minimised in order to allow time for the blade to ‘run in’.
Fault Finding
The bandsaw is fitted with a microswitch to prevent the saw from operating if the cover is opened whilst the saw is running. If the saw does not start, check the microswitch to ensure it operates correctly when the cover is closed. An audible click should be heard, when the cover is fitted, denoting the switch has closed. It may be necessary to adjust the mounting in order to achieve this.
Most operational problems with the saw can be corrected by adjusting blade tension, the blade guides or tracking. Poor adjustment will lead to the blade wandering, or not cutting in a straight line, or slipping from the wheels. It can even result in the blade breaking. Make sure the machine is always correctly set up and adjusted, and that the blade teeth are pointing downward toward the table. Similarly, if the blade is blunt or has lost its set, or is bent or cracked, it will not cut easily or in a straight line. A damaged or blunt blade must be replaced.

IMPORTANT: Before plugging in to the mains supply, the blade guard MUST be adjusted so that a minimum amount of blade is visible when cutting takes place. This is achieved as follows:
Offer the workpiece up to the blade, then lower the Upper Blade Guard by slackening the locking knob, (23, Fig.4) and tightening it again when the guard is as close to the workpiece as possible without interference.
When satisfied, plug the machine into the mains supply and observing all safety precautions previously stated, switch ON the machine by pushing the Green Knob on the control panel, marked ‘I’. Turn the white speed control knob to select the appropriate speed.
Feed the workpiece slowly into the blade, with a light pressure. Pushing too hard will cause the blade to twist, resulting in a poor cut, or even cause the blade to stall or break. Thicker or hardwood workpieces will need to be fed more slowly than thin, softer stock.
Keep your hands and fingers well clear of the blade when cutting.
Always use a push stick or piece of scrap to push the work when the cut line is close to the edge of the workpiece, or when cutting small workpieces.
When cutting curves with the bandsaw, make relief cuts to allow the blade to follow the cutting line. Do not try to cut to too small a radius as you can twist and break the blade.
If you want to back the blade out of a cut, stop the saw and wait for the blade to come to a halt before backing the workpiece gently off the blade.
Always switch the bandsaw off after use. NEVER leave the bandsaw running unattended.
Maintenance
WARNING!
removing the front cover.
The bandsaw requires very little maintenance other than routine adjustment and cleaning, and occasional inspection of the blade guides, blade and motor brushes.
Keep the saw clean, by clearing away sawdust and scrap frequently whilst working. When you have finished using the saw, remove the front cover and clear sawdust from inside the machine and around the motor vents using a vacuum cleaner or brush. Inspect the blade guides occasionally and replace them if they become worn.

WARNING!
Make sure the bandsaw is correctly assembled and adjusted
before use. Read and follow all safety instructions (see page 3)
The blade supplied with the saw is suitable for general purpose cutting of hard and soft
woods . It is not suitable for cutting metals (See restrictions of use, page 3). The speed of the bandsaw can be adjusted to suit the material by using the control knob below the on/off switch. Use slower speeds for harder materials.
A dust extractor may be used during use. Simply connect a suitable hose (not supplied),
from the dust extractor, to the dust extractor port (23, Fig.3). Dust Extractors are available from your Clarke dealer.
The saw is supplied with a mitre gauge to allow mitre cuts to be made.
Set the gauge to the desired angle, and use the guide slot in the table to gauge with the workpiece across the table, into the blade as shown in Fig. 6 .
run the mitre
The mitre gauge can also be used as a rip fence by placing it in the slot at right angles
to the blade. Fix it into place at the desired distance from the blade by using the countersunk screw in the slot. When using the mitre gauge as a rip fence you may wish to screw a suitable piece of hardwood or plywood (approximately 300 x 75 x 12 mm) to the face of the gauge to extend its length (fig 7).
The saw table can be tilted up to 45 degrees to allow you to cut bevels and compound
mitres. Slacken the table securing knobs, position the table to the desired angle, as shown on the scale beneath the table, and tighten the knobs (see fig 3).
NOTE: If accurate mitres are required, check the table angle using a suitable gauge between the table and blade. When adjusted, check to ensure the pointer is indicating the correct angle and adjust if necessary.

(d) Blade Guide Adjustments (Ref: fig 5)
NOTE: These adjustment are carried out at the factory. It is not therefore necessary to check or make readjustments before using for the first time.
These adjustments MUST be carried out periodically or whenever replacing a saw blade or whenever blade tracking adjustment is carried out.
The lower guide is located beneath the table as shown at 17, Fig.2; The upper guide is within the blade guard assembly shown at 18, Fig.2.
NOTE: It simplifies the procedure if the table is removed in order to gain easy access to the lower blade guides.
1. Slacken the guide lock nuts (28) and back off the guides, so that there is clearance between the guide and blade, and the support bearing locknut and back off the support bearing. (Support bearings are shown at 29, Fig.5)
NOTE: This procedure would have been carried out previously if a new blade is being installed, or if tracking has been reset.
2. Slacken the Guide Bracket securing screws (27) sufficiently to move the bracket laterally so that the guides are positioned approximately in the centre of the blade. They must not touch the teeth of the blade. When satisfied tighten the securing screws.
3. Screw in each guide until it makes light contact with the blade, then back off so that a clearance of not more than 0.5mm is achieved, then tighten the locknut. An ideal method of obtaining the correct clearance is to place a piece of paper between the guide and blade then screw in the guide until the paper is just nipped.
4. Screw in the Blade Support Bearings (shown at 29) until they make light contact with the back edge of the blade, then back off until a clearance of 0.5mm is obtained and tighten the locknut.

(3) Attach the Bandsaw to a Workbench
Fix the bandsaw to a suitable Workbench using screws or bolts (not supplied), through the holes in the feet with washers under the screw heads. Do not overtighten the securing screws.
1. Remove the table by fully unscrewing the two securing knobs, then slacken off all upper and lower blade guides as described under ‘Blade Guide Adjustments’ on page 10.
2. Correctly tension the blade as described under ‘Blade Tension’ on page 8.
3. Remove the front cover in order to gain access to the blade and wheels.
Adjustments
IMPORTANT: To achieve the best performance and maintain the maximum level of safety, certain adjustments must be made, BEFORE use.
WARNING! The machine MUST be disconnected from the mains supply before any adjustments are made.
(a) Table Adjustment (Ref: Fig. 3)
The screw (21) allows the table to be adjusted so that it is square to the blade.
With the table securing knobs (18) slackened, slide a small square across the table so that it contacts the side of the blade, then check to ensure the angle made is a right angle. If necessary turn the adjuster screw (21) clockwise or anticlockwise, whilst maintaining a slight pressure on the adjusting screw side of the table top, until the table is at 90 degrees to the blade. Tighten the table securing knobs, then check the table angle Indictor (20). If necessary, reposition the pointer so that it points to zero on the scale.
(b) Blade Tension (Ref: fig 4)
1. Slacken the blade tension locking knob (25) one full turn.
2. Adjust the blade tension Hex. socket head adjuster screw (24) a little at a time: clockwise to tighten increase tension, anticlockwise to decrease.
3. When correct tension has been achieved tighten the blade tension locking knob (25).
The blade needs to be tight enough to give a straight cut without allowing it to wander or slip or lose its tracking, but must not be so tight that it is rigid, there must be a certain degree of flexibility.
A few minutes using the machine will allow you to get a feel for correct blade tension.
If the saw is not to be used for some time we recommend that you release the tension on the blade. REMEMBER therefore to ALWAYS check blade tension before use.
WARNING!
Disconnect the bandsaw from the mains supply before
removing the front cover.
4. Carefully turn the driving wheel (16, Fig. 2) by hand to check blade tracking, taking care to keep fingers well clear of the blade, and not trapping them between the blade and the wheel. The blade must run true, as close to the centre of the rim of each wheel as possible.
5. Adjust the tracking by turning the Hex. socket head adjuster screw (26) a little at a
time....clockwise to move the blade inwards towards the motor side of the machine,
and anticlockwise to move it outwards. Turn the driving wheel by hand as you turn the adjuster screw.
6. Check blade tension once again after completing the tracking adjustment and adjust if necessary.
7. Replace the front cover (1), then adjust the Blade Guides as described in the following paragraphs.
Fig, (4)

26
(c) Blade Tracking (Ref: fig 4)
NOTE: This adjustment is carried out at the factory. It is not therefore necessary to check or readjust before use for the first time.
The adjustment MUST be made whenever replacing a saw blade or if the saw blade runs off the wheels.
The blade must ‘track’ correctly otherwise it will continually run off the drive and idler wheels. The blade should run in the middle of the wheels rims, and the procedure for checking and adjusting is as follows:
