Assembly; Operation; Fig.2 - Ferm DHM-1800 Gebrauchsanweisung

• Under normal operation, the tool is
designed to produce vibration. Check
tightness of screws carefully before
operation to avoid a breakdown or
accident.
• In cold weather or when the tool has not
been used for a long time, let the tool
warm up for several minutes by operating
it under no load. This will loosen up the
lubrication. Without proper warm-up
hammering operation is difficult.
• Always be sure you have firm footing. Be
sure no one is below when using the tool in
high locations.
• Hold the tool firmly with both hands.
• Keep hands away from moving parts.
• Do not point the tool at any one in the area
when operating. The bit could fly out and
injure someone seriously.
• Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.

wherever "live" electrical wire may be
encountered, do not touch any metal
parts of the tool!
Electrical safety
Always check that the mains voltage is
the same as on the type plate of the
machine.
Replacement of power cords or plugs
Immediately dispose of old cords and plugs
once they have been replaced. It is dangerous
to plug a loose power cord into a mains power
socket.
Use of extension leads
Only ever use approved extension leads that
are suitable for the power rating of the machine.
The minimum core thickness is 1.5 mm
Whenever using a reel extension lead, always
fully unroll the lead.

The auxiliary handle can be adjusted to several
positions to have a good control to the tool.

4. OPERATION
