Thank you for purchasing your new Clarke Metal Cutting Bandsaw, designed for light industrial use ONLY. Before attempting to operate this bandsaw please read this instruction manual thoroughly and follow all directions carefully. This is for your own safety and that of others around you, and to ensure the machine will provide long and trouble free service. Guarantee This product is guaranteed against faults in manufacture for 12 months from purchase date. Keep your receipt as proof of purchase.
General Safety Precautions For Operating Machinery WARNING! As with all machinery, there are certain hazards involved with their operation and use. Exercising respect and caution will considerably lessen the risk of personal injury. However, if normal safety precautions are overlooked or ignored, personal injury to the operator or damage to machinery may result. ✔ ALWAYS read the manual carefully. Know your machine.
✗ NEVER stand on the machine. Serious injury could occur if the machine is tipped over. Do not store materials above or near the machine such that it is necessary to stand on the machine to get to them. ✗ ✗ NEVER operate a machine when under the influence of alcohol, drugs or medication. NEVER force the machine. It will do the job better and safer, at the rate for which it was designed.
Electrical Connections Connect the mains lead to a standard 230V (50Hz) electrical supply through an approved 13Amp BS1363 plug, or a suitably fused isolator switch.
Know your Bandsaw Fig.
Assembly IMPORTANT! This machine cannot be handled without the use of lifting tools. Take all necessary precautions when manoeuvring. For ease of packing and transportation, the bandsaw comes partly assembled. It is therefore necessary to complete the assembly as follows. Unpack and lay out all the items and identify each one by referring to the Parts List and Fig. 1. Should there be any deficiency, you should immediately contact the dealer from whom the equipment was purchased.
before mounting the pulley cover. Having done so, lower the Pulley Cover over the shafts, ensuring the elongated hole is over the motor shaft. Replace the screw removed earlier through the pulley cover, into its hole in the circular plate. (This screw now locates and secures the pulley cover at the gearbox shaft). The only other mounting is beneath the pulley cover. Fit the mounting bolt supplied.
with the smallest diameter inwards, and the gearbox pulley with the smallest diameter outwards (as illustrated in the Parts Diagram). Locate the gearbox pulley on to its shaft, ensuring the grub screw lines up with the flat on the shaft. Tighten the grub screw fully. Fit the motor pulley to its shaft so that it lines up with the gearbox pulley. This may be done with a straight edge across the top of the pulleys to ensure the grooves are in line. When correctly aligned, tighten the grub screw provided.
Thread the ends of the handle through the corresponding holes in the right leg, and locate on the inside of the leg using the split pins provided. The wheel assembly comprises a bracket, axle and wheels. Attach the bracket to the base of the left leg using the nuts and bolts supplied. Thread the axle through the holes at the ends of the bracket, and insert the split pins in the holes provided in the axle, which will prevent any lateral movement.
2. BLADE GUIDE ASSEMBLY ADJUSTMENT The Metal Cutting Bandsaw is equipped with two adjustable blade guide assemblies, so that the blade guides may be individually adjusted to accommodate various widths of workpieces. To effect the most accurate cut and prolong the life of the blade, the blade guide assemblies should be adjusted to just clear the piece to be cut without impeding the lowering arm. This is carried out as follows: 1. Place the workpiece in the vice of Bandsaw and clamp tightly. 2.
5. CHANGING SPEED When using your Bandsaw always change the blade speed to best suit the material being cut. The material cutting chart in shown below. 1. With the power disconnected, loosen the Drive Belt Adjuster Bolt (item P) in order to slacken the drive belt, then open the pulley cover and change the position of the belt to gain the desired speed. 2. Re-tension the belt so that it may be depressed by 1/2” In the middle of its longest run. When satisfied, lock the motor firmly. 3.
4. Carefully feed the new blade between the blade guide bearings, ensuring the teeth are pointing DOWNWARDS, and then over the top pulley. Hold in position with one hand whilst stretching the blade downwards, and over the bottom pulley. Hold in place whilst applying slight tension by screwing the blade tension adjuster knob clockwise. 5. Ease the blade on to the pulleys as far as possible. 6. Tension the saw blade according to the instructions on page 10. 7. Place 2-3 drops of oil on the blade. 8.
8. ADJUSTING BLADE ANGLE When horizontal cutting, the blade must be at right angles (or vertical) to the bed. To achieve this: 1. Loosen the screw (A, Fig.4). 2. Adjust the blade guide (B, Fig.4) to make the blade vertical to the bed. 3. Place can engineers square on the bed to check the blade Is vertical, It not, repeat the process. 1 to 3. 4. Tighten the screw (11) Fig.4 LUBRICATION All bearings are lubricated for life. It is not necessary therefore to lubricate guide bearings etc.
Method Of Operation HORIZONTAL CUTTING Raise the arm to the vertical position. Open the vice to accept the piece to be cut by rotating the wheel at the end of the base anticlockwise. Place the workpiece on the saw bed. If the piece Is long it should be supported. Clamp the workpiece securely in the vice by turning the hand wheel clockwise. Switch on the machine, allow the head to lower slowly on to the work. Do not drop or force. Let the weight of the saw head provide the cutting force.
Trouble Shooting Symptom Excessive Blade Breakage. Premature Blade DuIling. Possible Cause(s) 1. 2. 3. 4. Material loose in vice. lncorrect speed or feed Blade pitch too large. Material too hard. 1. 2. 3. 4. 5. Incorrect blade tension. 6. Teeth in contact with mat’l before saw Is started. 7. Blade rubs on wheel flange. 8. Misaligned guide beatings. 5. 6. 1. Teeth too coarse. 2. Speed to great. 3. Inadequate feed pressure. 4. Hard spots/scale on material 5. Work hardening or material. 6.
