3. General Safety Instructions
For your own protection and for the protection of your electrical tool, pay attention to all parts of the text that are marked with this symbol!
WARNING – Reading the operating instructions will reduce the risk of injury.
Pass on your electrical tool only together with these documents.
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 mains-operated (corded) power tool or battery-operated (cordless) power tool.
3.1 Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
3.2 Electrical safety
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d) 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.
e) 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.
f) 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.
3.3 Personal safety
a) 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.
b) 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.
c) 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.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
f) 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.
g) 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.
3.4 Power tool use and care
a) 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.
b) 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.
c) 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.
d) 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.
e) 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.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g) 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.
3.5 Service
a) 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.
4. Special Safety Instructions
Pull the plug out of the plug socket before any adjustments or servicing are performed.
Avoid inadvertent starts: always switch the tool off when the plug is removed from the mains socket or if there has been a power cut.
Wear ear protectors. Exposure to noise can cause loss of hearing.
Always wear protective goggles, gloves, and sturdy shoes when working with this tool.
Secure the workpiece, e.g. using clamps.
Keep hands away from the cutting area.
Always switch on the machine before offering up to the workpiece.
Always work with the metal guide plate attached (3).

6. Commissioning
Before plugging in, check to see that the rated mains voltage and mains frequency, as stated on the rating label, match your power supply.
Australia: Always use a residual current device (RCD) protected supply with a rated residual current of 30 mA or less.
7. Use
7.1 Adjusting the Distance Between the Blades
The correct distance:
The distance between the blade (7) in the cutting base and the blade (6) in the ram should be approx a fifth of the thickness of the sheet material being cut (i.e. when cutting a sheet 1.6 mm thick, 0.2 x 1.6 = 0.32 mm). The distance should be slightly less if the material is tough and slightly more if the material is brittle.
The blades should not move.
Adjusting the distance:
- Loosen the screw (9) and if necessary, the grub screw (8) as well.
- Adjust the distance between the blade (7) in the cutting base and the blade (6) in the ram using a feeler gauge.
- Screw in the grub screw (8) until it rests against the blade (7) in the cutting base and then tighten the screw (9) again.
7.2 Switching On and Off
Switching on:
Push the sliding switch (2) forwards until it latches into position. The symbol "I" then appears from behind the sliding switch.
Switching off:
When the switch is set to on, press down the
ENGLISHen
raised rear end of the sliding switch (2) (switch position "0").
Avoid inadvertent starts: always switch the tool off when the plug is removed from the socket or if there has been a power cut.
7.3 Working With the Machine
• Always switch on the machine before offering up to the workpiece.
- Guide the machine so that the blade (7) in the cutting base is parallel with the workpiece.
- Guide the machine forwards without using excessive force.
- When cutting to the edge of sheet material (particularly when cutting along a scribe line), guide the machine so that the cutting base (10) is positioned on top (i.e. the machine upright with the blade in the ram below the workpiece).
8. Maintenance
Pull the plug out of the plug socket before any adjustments or servicing are performed.
8.1 Blades
The blades have four sharp cutting edges If one edge becomes blunt, rotate the blades 90^ to use the next sharp edge.
The blades are not designed to be sharpened. Replace the blades when all four cutting sites are blunt.
Never work with blunt blades!
Replacing the blades, see Section 9. (Accessories).
Blade (6) in the ram:
- Only for Ku 6870: Unscrew the screw for attaching the cutting base (4) and remove the cutting base (10).
- Unscrew the screw (5).
- Remove the blade (6), rotate 90° and insert again (so that the one cutting edge rests against the angled face of the ram).
- Tighten the screw (5) again.
- Only for Ku 6870: Attach the cutting base (10) again and secure with the cutting base screw (4).
Blade (7) in the cutting base:
- Unscrew the screw (9).
- Remove the blade (7), rotate 90° and insert again.
- Adjust the distance between the blades and secure the blade (7) again (see Section 7.1).
