General Power Tool Safety Warnings
WARNING – Read all safety warnings, instructions, illustrations and
specifications provided with this power tool. Failure to follow all
instructions listed below may result in electric shock, fire and/or serious
injury.
Save all safety warnings and information for future reference! The term “power
tool” in the safety warnings refers to your mains-operated
(corded) power tool or battery-operated (cordless) power tool.
Work area safety (62841)
- 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 power tool. 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 a 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.
- Do not let familiarity gained from frequent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
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 remove the battery pack, if detachable, 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 and accessories with care. 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.
- Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow safe handling and control of the tool in unexpected situations.
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.
Special Safety Instructions
Hold the power tool by insulated gripping surfaces, because the sanding
surface may contact its own cord. Cutting a “live” wire may make exposed metal
parts of the power tool “live” and could give the operator an electric shock.
Pull the plug out of the socket before making any adjustments, changing tools,
carrying out maintenance or cleaning.
Secure the workpiece against slipping, e.g. with the help of clamping devices.
Wear ear protectors when working for long periods of time. High noise levels
over a prolonged period of time may affect your hearing.
Hold the machine from the handles provided.
Reducing dust exposure:
WARNING – Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
- Lead from lead-based paints,
- Crystalline silica from bricks and cement and other masonry products, and
- Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how often you do this type
of work. To reduce your exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such as those dust masks that
are specially designed to filter out microscopic particles.
This also applies to dust from other materials such as some timber types (like
oak or beech dust), metals, asbestos. Other known diseases are e.g. allergic
reactions, respiratory diseases. Do not let dust enter the body.
Observe the relevant guidelines and national regulations for your material,
staff, application and place of application (e.g. occupational health and
safety regulations, disposal).
Collect the particles generated at the source, avoid deposits in the
surrounding area.
Use suitable accessories for special work. In this way, fewer particles enter
the environment in an uncontrolled manner.
Use a suitable extraction unit.
Reduce dust exposure with the following measures:
- do not direct the escaping particles and the exhaust air stream at yourself or nearby persons or on dust deposits,
- use an extraction unit and/or air purifiers,
- ensure good ventilation of the workplace and keep clean using a vacuum cleaner. Sweeping or blowing stirs up dust.
- Vacuum or wash the protective clothing. Do not blow, beat or brush.

On/Off switch, continuous activation
Press the trigger switch (5) to switch on the machine.
The trigger switch can be locked using the lock button (7) for continuous
operation. Press the trigger switch (5) again to stop the machine.
Setting the oscillating frequency
Set the oscillating frequency on the adjustment wheel (4). This can also be
done during operation.
The best way to determine the ideal setting is through a practical trial.
Dust extraction
To optimise the dust extraction performance, fit the sanding disc (1) so that
the holes on the sanding disc are aligned to the support plate (2).
Note: We recommend connecting a suitable extraction device when sanding
abrasive material (e.g. plaster, etc.).
Own extraction units:
Fit dust bag (8) to the ejection nozzle (3). Pull the dust bag (8) backwards
to remove it.
Empty the dust bag (8) in good time to optimise dust extraction.
Third-party extraction units:
Pull the dust bag (8) backwards.
Connect a suitable extraction device to the ejection nozzle (3).
Cleaning, Maintenance
Emptying the dust bag:
Remove the closure band (9). Empty the dust bag (8), clean with an extraction
device if necessary. Close the dust bag again with the closure band (9).
Clean the machine regularly. This includes vacuum cleaning the ventilation
louvres on the motor.
Replacing a worn support plate
- Remove the locking screw (10) of the support plate.
- Remove support plate (2).
- Refer to the Accessories chapter for replacement support plates with velcro-type fastening.
- Mount support plate (2) and rotate until it engages on carrier disc.
- Insert locking screw (10) again and tighten. Clean the support plate as required (vacuum off the dust). This increases the service life of the velcro-type fastening.
Replacing a support plate brake / braking ring If the idle speed of the
support plate increases in course of time, the braking ring (11) is worn and
must be replaced.
Note: If abrasive material (e.g. gypsum, etc.) is being sanded, the
braking ring inevitably wears faster.
- Remove the locking screw (10) of the support plate.
- Remove support plate (2).
- Replace the old braking ring (11) with the new braking ring (order no.: 344099810), ensuring that the new braking ring is in the same position as the old braking ring.
