DRUGS, ALCOHOL, MEDICATION. Do not operate machine while under the influence of drugs, alcohol or any medication. WARNING: 12. USE RECOMMENDED ACCESSORIES. The use of improper accessories could be hazardous. As with all machinery, there are certain hazards involved with their operation and use.
ELECTRICAL INSTALLATION ADDITIONAL SAFETY RULES FOR 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. • Make sure there are no nails or foreign objects in the part of the workpiece to be sawn.
UNPACKING PRINCIPAL PARTS Unpack the shipping carton and lay out all the items so that they may be clearly identified as follows: (Ref. Fig. 1) A Blade Tension Adjuster Knob • Main Frame Assembly complete B Upper Guide Block and Blade Guard Assembly. • Table Assembly C Wheel Cover Knobs • Mitre Gauge Assembly D Wheel Cover • Parallel Fence Assembly E Table Clamping Screw • 2 x Hex. Wrenches.
ASSEMBLY PREPARATION FOR USE All adjustments are factory set, except for those detailed below which MUST ALWAYS be checked before switching on the saw. 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. A.
C. Blade Guide Height DUST EXTRACTION The Upper Blade Guide must be adjusted according to the thickness of the workpiece to be cut. 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. Slacken off the Guide Block using knob (L, Fig. 1) and adjust the height of the guide so that it is no more that 5mm higher than the workpiece, then secure in this position. Please see your CLARKE dealer for details.
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. Fig. 7 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.
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 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. After use 1. Accumulated dust and chips should be removed from inside the bandsaw.
Fig. 12 Fig. 13 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. exactly in the centre of the tyre. This adjustment is effected by turning the Tracking Adjuster Knob (J, Fig. 11).
Simultaneously, slide the bearing to within 1/32” (0.4mm)of the back of the blade (shown in fig.16). Fig. 15 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. until the guides (C1) are positioned correctly. When correctly aligned, re-tighten screw (F). 1.
TROUBLE SHOOTING ALWAYS disconnect your bandsaw from the power supply when troubleshooting, or carrying out adjustments or maintenance. Fault Blades break Possible Cause 1. Faulty alignment (tracking) Remedy 1. Carry out tracking adjustments (p10) 2. Blade guides incorrectly adjusted. 2. Readjust Blade Guides 3. Feeding the work too fast. 3. Lower the feed rate 4. Forcing or twisting the blade around a tight radius. 4. For tight curves, make relief cuts, fairly close together, at 90º to the curve 5.
