remove the machine from the workpiece or pull it
backwards as long as the tool is moving or could
recoil.
- If you want to restart a tool that is stuck in the
workpiece, centre the tool in the tool gap and
check whether the teeth of the tool have got
jammed in the workpiece.
- Support large plates to reduce the risk of a
backlash caused by a jammed tool.
- Do not use any blunt or damaged tools.
- Be especially careful when making a "plunge cut"
into a concealed area, e.g. into an existing wall.
- Prior to every use, check whether the saw guard is
closing properly. Do not use the groove-cutting
machine if the saw guard is unable to move freely
and does not close immediately. Never clamp or
tie down the saw guard in an open position.
- Check the state and function of the spring for the
saw guard. Have the machine serviced prior to use
if saw guard and spring do not work properly.
- When carrying out plunge cuts, always secure the
base plate of the machine against dislocation to
the rear.
- Do not place the groove-cutting machine onto the
workbench or floor without the saw guard covering
the tool.
- Examine the workpiece for foreign objects. Do not
saw or mill into steel parts.
Instructions on service and maintenance:
- Regularly cleaning the machine, especially the
adjusting devices and guides, constitutes an
important safety factor.
- Only original MAFELL spare parts and accessories
may be used. Otherwise the manufacturer will not
accept any warranty claims and cannot be held
liable.

Setting / Adjustment
4.1 Mains connection
Prior to commissioning make sure that the mains
voltage complies with the operating voltage stated on
the machine's rating plate.
4.2 Chip extraction
Danger
Substances that are harmful to
health must be taken up with an M-
suction device.
Connect the machine to a suitable external dust
extractor during all work generating a considerable
amount of dust. The air velocity must be at least 20
m/s (65.6 ft / sec.).
The internal diameter of hose connector 1 (Fig. 1) is
35 mm (1 3/8 in.).
4.3 Cut quality
Use a sharp tool to achieve a good cut quality. Select
a tool from the list in chapter 4.5 according to the
material.
4.4 Secure machine against tilting
The cover of the groove-cutting machine is equipped
with a glider as support against tilting. The glider must
be turned for the respective application (with or
without rail).
Unscrew the fastening screw 27 (Fig. 1) using
the Allen key 4 (Fig. 2).
Rotate the glider 28 (Fig. 1) around the
fastening screw until the printed diagram on the
glider (right) corresponds to the desired
application (with or without rail). (Adjusting
screws 26 (Fig. 1), which can be adjusted with
the Allen key 4 (Fig. 2) are located at the bottom
/ top side of the glider for fine adjustment of the
glider).
Retighten the fastening screw 27 (Fig. 1).
