1. Safety
Warning!
In order to minimise the risk of fire, electric shock or personal injury, certain basic safety precautions must always be observed when using this machine. Read this instruction manual carefully before using the product and save this manual for future reference.
- Keep the working area tidy. Cluttered surfaces and benches invite accidents.
- Take stock of your working environment. Do not expose the tool to rain. Do not use the tool in moist or wet areas. Keep the working area well lit. Never operate the tool near flammable liquid or gas.
- Avoid electric shocks. Avoid body contact with earthed objects such as pipes, radiators, ovens or refrigerators.
- Keep other people at a safe distance. Do not allow anyone, especially children, not involved in the work process to touch the tool or its electric cable. Keep all bystanders at a distance.
- Store the tool in a safe place. When your tools are not in use, keep them in a locked, dry area, away from children.
- Do not force the tool. The tool will work better and safer at the feed rate for which it was intended.
- Use the correct machine. Do not try to use small tools to perform jobs requiring more powerful tools. Do not use a tool for a purpose for which it was not designed, e.g. using a circular saw for lopping branches off trees.
- Wear suitable attire. Do not wear loose-fitting clothing or jewellery; they could be caught in moving parts. Non-slip shoes are recommended for outdoor work. Wear a hairnet or similar if you have long hair.
• Always use safetywear. Wear safety glasses. Use a dust mask or dust filter when working in dusty environments.
- Use dust extractors. If the tool is equipped with or connected to a dust extractor/collector, make sure that it is turned on and used correctly.
- Do not abuse the lead. Do not jerk the lead, grip the plug itself when disconnecting the power. Make sure that the mains lead does not come into contact with heat, oil, or sharp edges.
- Firmly secure the workpiece. If possible use vices or clamps to hold the workpiece in place. This is much safer than holding the workpiece in one hand.
- Do not overreach. Make sure that you stand steady and balanced all times.
- Look after you tools. Make sure that they are clean and that the edges are sharp for maximum effect and best results. Follow the manual's recommendations regarding lubrication and replacement of accessories. Inspect the mains lead regularly. If it is damaged it should be replaced by a qualified service technician. Inspect all leads and cables regularly to check for any damage. Make sure that the machine's handles and controls are clean, dry and free from oil and grease.
- Have any defective power switches replaced at a qualified service centre.
- Do not use the product if the ON/OFF switch does not function properly.
- Turn the power off. Pull out the plug and push in the emergency stop button before servicing or changing any blades, drill bits, cutters or sanding discs.
- Remove all spanners and repair tools. Make a habit of checking to make sure that the machine is free of all spanners and tools before turning the power on.
-
Avoid accidental starts. Do not walk around with your finger on the trigger of a power tool if it is plugged in. Make sure that the ON/OFF switch is set to OFF before plugging in any power tool.
-
Use the correct extension leads. If you use extension leads outdoors, only use those designed for outdoor use. Only use extension leads with thick enough diameter core wires and roll out the whole lead.
- Use common sense and be careful. Think before carrying out any task, so that it is carried out safely. Never operate machines/power tools when you are tired or under the influence of medicine.
-
Check the following before turning the tool on:
-
That all guards and other parts are whole and in working order.
- That moving parts are free and correctly aligned.
- That no moving parts can get caught.
- That there are no visible defects.
-
Other factors that can influence work execution.
-
Use only recommended accessories. The use of accessories which are not recommended by the manufacturer may present a risk of personal injury.
- Check that the tool conforms to current safety regulations. Repairs to the tool should only be carried out by a tradesman using original spares; otherwise the tool could cause accidents and personal injury.
Additional safety instructions
- If using a floor stand, make sure that the band saw is securely fastened to the stand and that the stand is properly assembled and securely fastened to the floor.
• Make sure that the band saw is positioned in such a way that the workpiece can be worked on in a safe manner. - This saw must not be used for wet cutting. Doing so can lead to deadly electric shocks. This band saw is only intended for dry cutting.
- The drive belt must not be put under too much tension; it will last longer if the tension is released when the saw is not in use.
- Do not allow the build-up of sawdust around the motor or inside the machine. Piles of sawdust are a fire hazard.
- The sawblade must not be stopped through the exertion of pressure on the workpiece or by apply force to the sides of the blade.
- The machine's safety guards must be in place and functioning properly. Always check that the blade guides are correctly aligned.
- Never turn the machine on if the saw blade is in contact with the workpiece.
- Make sure that there are no nails or screws in the workpiece which could damage the saw blade.
- Do not attempt to modify the machine or its accessories in any way.
- Do not apply too much pressure to the workpiece when feeding it into the saw blade. A steady feed rate reduces wear on the saw and saw blade and consequently increases the efficiency and useful life of the band saw. Replace any worn table inserts.
- Connect the band saw to a dust extractor before starting to saw. The saw must not be used if any of its panels is open or if the blade guard is not in place.
- Select an appropriate saw blade and sawing speed for the type of workpiece.
- When sawing with a tilted table, position the guide on the lower side of the table.
- Position the blade guard as close to the workpiece as possible.
Saw blade safety
- Use only blades recommended by the manufacturer/supplier.
- Do not use a damaged or deformed saw blade. Doing so could result in considerable danger to the user or damage to the machine.
- The direction marked on the saw blade should correspond to the direction of the pulley's rotation.
-
The teeth of the blade should be pointing downwards when the blade is viewed from the side.
-
Release the blade tension when the saw is not used. Always wear safety gloves and safety glasses when fitting or removing a saw blade.
- Always roll up the saw blade in an open area away from other people. Store the blade coiled up and protected with fastening wire.
• Always keep your fingers away from moving saw blades.
Specific safety instructions for band saws
- Never use damaged or deformed saw blades.
- Replace the table insert when it is worn or damaged.
- Do not clean the saw blade whilst it is in motion.
- Connect a dust extraction device to the band saw when sawing wood.
- Do not turn the saw on when one of the blade pulley wheel covers is open or if any of the blade guards are not in place.
- Make sure that you use the correct blade speed for the material that is to be cut.
- When transporting the saw, the upper blade guard should be lowered over the blade to protect it.
- When sawing cylindrical workpieces, a clamp should be used to prevent the workpiece from twisting.
- When sawing tall workpieces, a clamp should be used to prevent the workpiece from tipping over.
- The band saw must only be used with compatible accessories and only for the purpose for which it was designed.
- Do not allow children to use the machine.
The most frequent dangers when band sawing are
- Dangers associated with the moving saw blade, such as sharp teeth.
- Off-cuts from the workpiece which can be ejected towards the user.
- Kickbacks from the workpiece.
Despite the fact that the band saw has been fitted with all the necessary safety devices and conforms to relevant safety standards, the following hazards still exist
• Hearing damage caused by high noise levels.
- The risk of an accident in the unprotected area around the saw blade.
- The risk of injury when changing the saw blade.
- The risk of flying off-cuts or wood chips.
- Trapped fingers.
- Workpiece kickback.
- The risk of inhalation of harmful dust, especially oak and beech sawdust.

The blade guides minimise blade movement during sawing.
-
After the blade has been centred on the blade pulley wheels, make sure that the teeth of the blade do not line up with the guide pins (18), if they do the entire guide pin post and support bearings can be moved back so that the teeth of the blade do not foul the guide pins.
-
The guide bearings should be 0.2 mm from the side of the blade.


-
Rotate the wheel by hand and make sure that the joint of the blade passes through the guides.
-
Position the rear support bearing (19) as close to the back of the saw blade as possible without it coming into contact.

4. Operation
Start/stop button
This saw is fitted with a no-volt release switch which prevents the saw from automatically starting again following a power cut or if the mains plug is reconnected to the mains supply after the machine has been stopped by being unplugged with the ON/OFF switch set to ON.
The saw is switched on by pushing in the green [1] button and switched off by pushing in the red [0] button.

natural_image

- The upper blade guide assembly should be lowered to as close a position to the workpiece as possible. To lower the assembly, loosen the locking knob (6) and slide the assembly down. Tighten the locking knob.
- Set the rip fence to the desired width. Plan the cut before starting to saw. When sawing a small workpiece, use a push stick to ensure that your hands do not come too close to the blade.
- Before sawing a large workpiece, make sure that there is enough room around the saw for the workpiece to be manoeuvred safely. If necessary, you should also make sure that the workpiece is supported to avoid undue stress on the blade. Cut the material at a steady, even pace. A clear sign that the sawing is being forced too quickly is the motor changing pitch or slowing down.

Note
• Make sure that the saw blade undamaged and is centred on the blade pulley wheels before starting to saw.
- Feed the workpiece into the blade carefully making sure not to exert too much pressure.
- Hold the workpiece in both hands if you can or use a push stick if the workpiece is too small.
• Always keep your hands well away from the saw blade and think through the cut before starting.
- For the best results, use a sharp saw blade.
- Select the correct saw blade for the thickness of the workpiece and type of cut. Thin and hard woods require finer toothed blades than thicker, softer woods.
- Tight radii require a narrower blade than straight cuts.
- Use the rip fence as a support when making straight cuts.
- Think about a cut before beginning to saw a workpiece, you might need to reposition the workpiece or turn it over. Mark out the cut on both sides of the workpiece if necessary.
- Never twist the workpiece without it being pressed against the saw blade, otherwise the workpiece can become stuck or the blade can bend.
• Always unplug the band saw before making any adjustments or repairs and whenever the saw is not to be used.
Using the mitre gauge
- Make a practice cut with the gauge set to 0^ and then check the cut using a try square.
- If adjustment is necessary, loosen the screw holding the pointer and move the pointer accordingly.
- Set the desired angle on the mitre gauge and make the cut whilst holding the workpiece firmly against the mitre gauge.
