E N G L I S H
d 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.
e Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tools operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
f Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g Use the power tool, accessories and tool bits
etc., in accordance with these instructions
and in the manner intended for the particular
type of power tool, 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.
5 Service
a 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.
Additional safety rules for grinders
• Your grinder has been designed for grinding and
cutting masonry and steel.
Do not cut or grind light metal with a
magnesium content exceeding 80%
since this type of metal is flammable.
• Do not use any accessories other than fibre
reinforced grinding and cutting discs.
• Use only plain or centre-recessed grinding and
cutting discs.
• Use the grinding and cutting discs recommended
by the manufacturer only.
• The max. allowable speed of the grinding wheel
or cutting disc, or any other suitable accessory,
must always be equal to or greater than the no-
load speed of the tool specified on the nameplate.
• Do not cut workpieces requiring a maximum
depth of cut exceeding that of the cutting disc.
