spinning wheel may grab the surface and pull the
power tool out of your control.
o) Do not run the power tool while carrying it
at your side. Accidental contact with the spinning
wheel could snag your clothing, pulling the wheel
into your body.
p) Regularly clean the power tool's air vents.
The motor's fan will draw the dust inside the
housing and excessive accumulation of powdered
metal may cause electrical hazards.
q) Do not operate the power tool near
flammable materials. Sparks could ignite these
materials.
r) Do not use wheels that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel. Pinching or snagging
causes rapid stalling of the rotating wheel which
in turn causes the uncontrolled power tool to be
forced in the direction opposite of the wheel's
rotation at the point of the binding.
a) Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use auxiliary
handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or
kickback forces, if proper precautions are taken.
b) Never place your hand near the rotating
wheel. Wheel may kickback over your hand.
c) Do not position your body in line with and
behind the rotating wheel. Kickback will propel
the tool in direction opposite to the wheel's
movement at the point of snagging.
d) Use special care when working corners,
sharp edges etc. Avoid bouncing and
snagging the wheel. Corners, sharp edges or
bouncing have a tendency to snag the rotating
wheel and cause loss of control or kickback.
e) Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades create
frequent kickback and loss of control.
f) Do not " jam" the wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases
the loading and susceptibility to twisting or binding
of the wheel in the cut and the possibility of
kickback or wheel breakage.
g) When wheel is binding or when interrupting
a cut for any reason, switch off the power tool
and hold the power tool motionless until the
wheel comes to a complete stop. Never
attempt to remove the wheel from the cut while
the wheel is in motion otherwise kickback may
occur. Investigate and take corrective action to
eliminate the cause of wheel binding.
h) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted in
the workpiece.
i) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag under
their own weight. Supports must be placed under
the workpiece near the line of cut and near the
edge of the workpiece on both sides of the wheel.
j) Use extra caution when making a "pocket
cut" into existing walls or other blind areas.
The protruding wheel may cut gas or water pipes,
electrical wiring or objects that can cause
kickback.
Always wear safety goggles, gloves, hearing
protection and work shoes when working with your
power tool!
Wear safety goggles
Before starting work make sure (e.g. with a metal
detector) that there are no power, water or gas
lines in the wall at the spot the chase is to be cut.
When working with the wall chaser always use
the side handle (2) supplied with the tool.
Dust from material such as paint
containing lead, some wood
species, minerals and metal may
be harmful. Contact with or
inhalation of the dust may cause
allergic reactions and/or
respiratory diseases to the
operator or bystanders.
Certain kinds of dust are classified as
carcinogenic such as oak and beech dust
especially in conjunction with additives for wood
conditioning (chromate, wood preservative).
Material containing asbestos must only be treated
by specialists.
- To achieve a high level of dust collection, use a
suitable Metabo vacuum cleaner together with
this tool.
- The work place must be well ventilated.
- The use of a dust mask of filter class P2 is
recommended.
Follow national requirements for the materials you
want to work with.
The diamond cutting blades must fit without play
in relation to the support flange. Do not use
adapters or reducers.
Diamond cutting blades must be stored and
handled with care in accordance with the
manufacturer's instructions.
