Safety Instructions

General Power Tool Safety Warnings
WARNING Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators.
  There is an increased risk of electric shock if your body is earthed or grounded.

• Do not expose power tools to rain or wet conditions.
  Water entering a power tool will increase the risk of electric shock.

• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts.
  Damaged or entangled cords increase the risk of electric shock.

• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock..

• If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

Personal safety

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

• Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool.
  Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

• Dress properly. Do not wear loose clothing or jewellery.
  Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

Power tool use and care

• Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.

• Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

• Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.

• Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation.
  If damaged, have the power tool repaired before use.
  Many accidents are caused by poorly maintained power tools.

• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

• Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

Battery tool use and care

• Recharge only with the charger specified by the manufacturer.
  A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.

• When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another.
  Shorting the battery terminals together may cause burns or a fire.

• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

Service

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Safety Instructions for Band Saws
Safety Instructions for Handheld Band Saws

• Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessories contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
• Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by your hand or against the body leaves it unstable and may lead to loss of control.
• Only bring the power tool into contact with the workpiece when switched on. Otherwise there is danger of kickback if the cutting tool jams in the workpiece.
• When the cut is completed, switch off the power tool and then pull the band saw blade out of the cut only after it has come to a standstill. In this manner you can avoid kickback and can place down the power tool securely.
• Hold the power tool firmly with both hands and make sure you have a stable footing. The power tool can be more securely guided with both hands.
• Always wait until the power tool has come to a complete stop before placing it down. The application tool can jam and cause you to lose control of the power tool.

General Base Unit Safety Warnings

WARNING Read all safety warnings and all instructions provided with the base unit and the power tool to be mounted. Failure to follow the warnings and instructions may result in electric shock,fire and/or serious injury.
Save all warnings and instructions for future reference.

• Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments or changing accessories. Accidental starting of the power tool is a cause of some accidents.

• Properly assemble the base unit before mounting the tool. Proper assembly is important to prevent risk of collapse.

• Securely fasten the power tool to the base unit before use. Power tool shifting on the base unit can cause loss of control.

• Place the base unit on a solid, flat and level surface.
  When the base unit can shift or rock, the power tool or workpiece cannot be steadily and safely controlled.

• Do not overload the base unit or use as ladder or scaffolding.
  Overloading or standing on the base unit causes the stand to be “top-heavy” and likely to tip over.

Safety Instructions for Mounted Band Saws

• Correctly secure the base unit on a stable, even and horizontal surface. If the base unit can slip or shake, the power tool cannot be operated safely.
• Securely attach the power tool to the base unit before use. You may lose control of the power tool if it slips on the base unit.

Additional Safety Warnings

• Keep hands away from the sawing area. Do not reach under the workpiece. Contact with the saw blade can lead to injuries.

• Use only undamaged band-saw blades that are in perfect condition. Bent or dull band-saw blades can break or lead to kickback.

• Keep lubricants or oil away from the band-saw blade.
  Completely wipe off excess oil before cutting. Otherwise, the band-saw blade can slip.

• Do not apply strong pressure to the band-saw blade during operation. Excessive pressure can cause the band-saw blade to slip or break. This poses a risk of injury.

• After switching off, do not stop the band-saw blade by applying lateral pressure to it. The band-saw blade can become damaged, break or lead to kickback.

• Do not touch the band-saw blade directly after the working process until after it has cooled down. The band-saw blade becomes very hot while working.

• In case of damage and improper use of the battery, vapours may be emitted. The battery can set alight or explode.
  Ensure the area is well ventilated and seek medical attention should you experience any adverse effects. The vapours may irritate the respiratory system.

• Do not open the battery. There is a risk of short-circuiting.

• The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally.
  An internal short circuit may occur, causing the battery to burn, smoke, explode or overheat.

• Only use the battery in the manufacturer’s products.

This is the only way in which you can protect the battery against dangerous overload.
Protect the battery against heat, e.g. against continuous intense sunlight, fire, dirt, water and moisture. There is a risk of explosion and short- circuiting.

If the power tool is overloaded or the permitted battery temperature is exceeded, the electronics of the power tool will switch off until the temperature returns to within the optimum operating temperature range.

Working Advice

• Lock the tool arm for all work on the saw table or power tool.
  Select a suitable sawing position for your workpiece, so that as many teeth as possible of the bandsaw blade (13) are in the cut (see figure T).
  Work with moderate pressure and uniform feed.

Freehand Operation (see figures U−V)

• Hold the power tool firmly with both hands and make sure you have a stable footing. The power tool can be more securely guided with both hands.
  For freehand cutting, pull the guide (12) out as far as required.
  Switch on the power tool and wait for the motor to reach the required speed. Place the power tool onto the workpiece using the guide (12) and slowly lower the bandsaw blade (13) into the workpiece (see figure U).

Sawing Close to Walls (see figure V):
When sawing close to walls, the bandsaw blade must be positioned to the side of the saw blade guides (20). The guide (12) must be pushed back as far as it will go.
Switch on the power tool and wait for the motor to reach the required speed. Place the power tool with the two guide plates (11) flush against the wall. Slowly lower the bandsaw blade (13) into the workpiece.
Reduce the pressure just before ending the cut and slightly raise the power tool, so that it does not fall on the workpiece.

Sawing in a Fixed Position (see figure W)

• Do not stand in line with the saw blade in front of the power tool. Always stand to the side of the saw blade.
  Slowly lower the power tool into the cut with one hand on the auxiliary handle. This protects your body against possible kickback.
  When sawing in a fixed position, the guide (12) must be pushed back as far as it will go.
  Switch on the power tool and wait for the motor to reach the required speed. Unlock the locking mechanism of the tool arm (25) (see “Locking/Loosening the Tool Arm (see figure M)”, page 17). Push the auxiliary handle (2) down and slowly lower the bandsaw blade (13) into the workpiece.
  After finishing the cut, switch off the power tool and wait until the bandsaw blade (13) has come to a complete stop.
  Push the power tool so that the auxiliary handle (2) faces upward.

Adjusting the Blade Tracking (see figures X−Y)
Regularly check the height of the bandsaw blade (13) on the roller (18). The distance between the bandsaw blade and the upper edge of the roller must not exceed 3 mm. If the distance is larger than this, the blade tracking must be readjusted:

1. Loosen the locking nut for the blade tracking (22) anticlockwise using the socket spanner (23).

2. Turn the screw for adjusting the blade tracking (24) by one rotation using a commercially available crossheaded screwdriver:
   To lower the bandsaw blade(13) , turn the screw (24) clockwise.
   To raise the bandsaw blade (13), turn the screw (24) anticlockwise.

3. To preselect the blade speed, set the thumbwheel (5) to setting 1.

4. Insert a rechargeable battery (4).

5. Switch on the power tool and allow the bandsaw blade (13) to run for one rotation.

6. Switch the power tool off and remove the rechargeable battery (4).

7. Check the height of the bandsaw blade (13) on the roller (18). If necessary, repeat steps 2 to 5 until the distance between the bandsaw blade and the upper edge of the roller is under 3 mm.

8. Retighten the locking nut for the blade tracking (22) clockwise using the socket spanner (23).

Note: The screw for adjusting the blade tracking (24) only changes the height of the roller being driven (18). This enables the entire track of the bandsaw blade (13) to be adjusted.

Utility hook (not for sawing in a fixed position)
Your power tool is equipped with a hanging hook (15) to hang it from when it is switched off. To prevent injuries and damage, only hang the power tool using a stable and suitable means of attachment.

• When the power tool is hung up, take care that the saw blade is protected from accidental contact. This poses a risk of injury.

Transporting the Saw Table
If the power tool is fitted on the saw table, remove the battery (4) from the power tool before transporting it.
Lock the tool arm (25) in the lower position (see “Locking/Loosening the Tool Arm (see figure M)”, page 17). Hold the saw table by the spindle handle (36) and remove it using the transport wheels (28).

Storing the Power Tool
If you do not use the power tool over an extended period of time, release the pre-tensioning of the bandsaw blade (13) to extend the service life of the bandsaw blade. To do this,swivel the pre-tension lever (14) as far as it will go in the direction.

Before recommissioning the power tool, swivel the pre-tension lever (14) as far as it will go in the direction in order to tension the bandsaw blade (13). Check whether the bandsaw blade (13) is correctly running in the saw blade guides (19) and around the rollers (18).
