.
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.
- Wear protective gloves during all maintenance and servicing work.
- 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
- 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 work on workpieces that are too small or too large for the machine capacity.
- Mount cutting chain and guide rail properly and keep them in order. Prior to reusing a defective cutting
chain, repair it properly. Use only sharp cutting chains!
- Use only type 100 cutting chain assemblies for a machine without FG 150 guide rack!
- Remove the chain guard only for tool change. Screw it back on immediately afterwards. Never work without
chain guard!
- Never transport the chain mortiser with cutting chain running. Avoid any contact of the running cutting chain
with the soil!
- Never clamp the switch.
- Prior to switching on the machine check to ensure that the cutting chain is properly tensioned.
- Whenever possible, secure the workpiece, for example with screw clamps, against swinging away, slipping,
tipping over or bobbing up.
- Do not start mortising the workpiece before the cutting chain has reached its full rotational speed.
- Check the workpiece for foreign bodies. Never mortise into metal parts, such as nails.
- Hold the machine with both hands before you switch it on.
- Switch on the machine only when there is not contact between the cutting chain and the workpiece. Position
the machine for mortising when the cutting chain is running.
- While you are mortising, ensure that the connecting cable always runs towards the rear, away from the
machine.
- Adjust the mortising feed rate to the material thickness. Mortising too quickly will overload the motor, results
in improper mortises, and causes the cutting chain to be blunt more quickly.
- Do not remove the machine from the workpiece before the cutting chain has stopped.
- Never reach into the chip ejector and into the unprotected area of the cutting chain while the machine is
running.
- Before switching on the machine during freehand milling, make sure that the transverse guide fence is
fastened and is in contact with the workpiece. Do not mill without the transverse guide fence!
- Only use the machine outdoors or in well ventilated rooms.
