.
Work area
- Children and adolescents are not allowed to operate this machine.
- When using the machine outdoors, the use of an earth leakage circuit breaker is recommended.
- Replace damaged cables or plugs immediately. To avoid safety hazards, only MAFELL or an authorized
MAFELL service workshop is allowed to replace parts.
- Prevent sharp kinks of the cable. Do not wrap the cable around the machine, especially when transporting
and storing the machine.
- Do not use this machine when you are tired, or under the influence of drugs, alcohol or medicaments. Be
aware of what you are doing. Stay alert and use common sense.
- Keep children and bystanders at a distance while you are operating the machine. Distractions can cause
you to lose control of the machine.
- Use eye protection, dust mask and hearing protection. Appropriate safety equipment, used
under proper conditions, will reduce the risk of injuries.
Instructions for service and maintenance:
- Cleaning the machine regularly, especially the adjustment elements and the guiding devices, is an important
safety factor.
- Ensure that only genuine MAFELL spare parts and accessories are used. Failure to do so will make
warranty claims and the liability of the manufacturer null and void.
- Prepare a periodic maintenance schedule for your machine. When you clean the machine, be careful
not to disassemble any part of the machine. Reassembling the machine bears the risk that internal
wires are routed incorrectly or pinched, or that return springs of the safety device are mounted
incorrectly. Certain cleaning agents, such as gasoline, carbon tetrachloride, ammonia, etc. can damage
plastic parts.
- Some of the dust produced by sawing, sanding, drilling and other building work 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,
- Arsenic and chromium from chemically treated wood.
Your risk from this hazard varies with the frequency at which you perform this type of work. To reduce your
exposure to these chemicals: Work in a well-ventilated area. Work only with approved safety equipment,
such as dust masks that are specially designed to filter out particles of microscopic size.

3.4 Specific safety rules
Sawing method
- Wait for the cutter top stop before setting the tool down. An exposed rotating cutter may engage the
surface leading to possible loss of control and serious injury.
- Hold the power tool by insulated gripping surfaces, because the cutter 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.
- Use clamps or another practical way to secure and support the workpiece to a stable platform.
Holding the workpiece by your hand or against the body leaves it unstable and may lead to loss of control.
- Never reach into the planer shaft or chip ejector while the machine is running.
- Hold the machine tight and support it before you switch it on.
- Ensure that you stand in an unobstructed and non-slip area with adequate lighting.
- Always pull out the power plug before you change tools, make adjustments, or eliminate malfunctions (this
also includes removing trapped chips).
- Never clamp the operating lever.
- Never work on workpieces that are too small or too large for the machine capacity.
- Do not start planing the workpiece before the planing shaft has reached its full rotational speed.
- While you are planing, ensure that the connecting cable always runs towards the rear, away from the
machine.
- Check the workpiece for foreign bodies. Do not plane over metal parts, such as nails.
- Uniform and steady feed during planing increases the service life of blades and machine and reduces the
risk of accidents. Never plane backwards or in a plunging process!
- The planing blades must be turned or changed in good time, as blunt blades not only increase the risk of
kickback, but also put unnecessary strain on the motor.
- Use a suitable tool, such as a piece of wood, to clean a clogged hose connector. Never reach into the
discharge connector.

4.3 Chip extraction
Caution
Health hazards from wood dust
The dusts produced during work can be inhaled and can cause health damage.
➢ Harmful dust must be extracted with a HEPA 13 dust extractor.
➢ Wear a dust mask during work.
The carpenter's planer is designed such that proper chip ejection is ensured when planing at proper feed rate
and fully utilized planing width. In this process, the chips are ejected sideways so that the view of the
workpiece is not obstructed.
For all work that produces a significant amount of dust, connect the machine to a suitable external extraction
device. The air velocity must be at least 20 m/s [65 ft/sec].
The inside diameter of the hose connector is 75 mm [2.95 in].
4.4 Blade change
Caution
Risk of injury from the tool
The blades on the planing shaft are sharp. You can hurt yourself when you work
on the tool.
➢ Wear protective gloves when you handle the tool.
➢ Be careful when you handle the tool.
Sharp planing blades guarantee a proper planing result and put less strain on the motor. Therefore, replace or
turn blunt planing blades in time.

5.5 Working information
Prior to switching on the machine, position its base plate on the workpiece such that there is no contact yet
between the planing shaft and the workpiece.
Once the machine has reached its full rotational speed, hold the machine with both hands on the handles (2)
and guide it steadily over the workpiece. A steady feed results in a clean planing surface and is gentle on the
machine.
When working with full planing width, the guide roller (6) can serve as a lateral guide fence.
Use the following procedure for a lateral
guidance:
1. Release the knurled knob (5).
2. Swing down the guide roll (6).
3. Tighten the knurled knob (5).
4. Move the machine with the guide roll (6)
laterally against the workpiece and guide it
along the workpiece.
✓ Lateral guidance active.

Do not remove the machine from the workpiece with the planing shaft running.
The rotational speed of the planing shaft drops in case of overload.
Switch the machine off and back on. Wait until the planing shaft has reached its full
rotational speed again. Continue working then at a reduced feed rate.
At a chip removal 0, the switched-off machine can be put down on a flat surface without
damaging the support.
