g) If devices are provided for the connec-
tion of dust extraction and collection fa-
cilities, ensure these are connected and
properly used.
Use of dust collection can
reduce dust-related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the cor-
rect power tool for your application. The
correct power tool will do the job better
and safer at the rate for which it was de-
signed.
b) Do not use the power tool if the switch
does not turn it on and off. Any power
tool that cannot be controlled with the
switch is dangerous and must be re-
paired.
c) Disconnect the plug from the power
source and/or the battery pack from the
power tool before making any adjust-
ments, changing accessories, or storing
power tools.
Such preventive safety
measures reduce the risk of starting the
power tool accidentally.
d) Store idle power tools out of the reach of
children and do not allow persons unfa-
miliar with the power tool or these in-
structions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for mis-
alignment or binding of moving parts,
breakage of parts and any other condi-
tion that may affect the power tool’s op-
eration. 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. Prop-
erly 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 in-
structions, taking into account the work-
ing conditions and the work to be per-
formed.
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 qual-
ified repair person using only identical
replacement parts.
This will ensure that
the safety of the power tool is maintained.
Machine-specific
Safety Warnings
Safety warnings for wall chasers
Read all safety warnings, instruc-
tions, illustrations and specifica-
tions provided with this power
tool.
Failure to follow all instruc-
tions listed below may result in
electric shock, fire and/or serious
injury.
f
Always use guard provided with the tool.
The guard must be securely attached to the
power tool and positioned for maximum
safety, so the least amount of wheel is ex-
posed towards the operator. Position your-
self and bystanders away from the plane of
the rotating wheel.
The guard helps to pro-
tect operator from broken wheel fragments
and accidental contact with wheel.
f
Use only diamond cut-off wheels for your
power tool.
Just because an accessory can
be attached to your power tool, it does not
assure safe operation.
f
The rated speed of the accessory must be at
least equal to the maximum speed marked
on the power tool.
Accessories running fast-
er than their rated speed can break and fly
apart.
f
Wheels must be used only for recommend-
ed applications. For example: do not grind
with the side of cut-off wheel.
Abrasive cut-
off wheels are intended for peripheral grind-
ing, side forces applied to these wheels may
cause them to shatter.
