carefully re-enter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted in
the workpiece.
g) 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.
h) 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.
4.4 Safety warnings specific for wire
brushing operations:
a) Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive
load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
b) Allow brushes to run at operating speed for
at least one minute before using them. During
this time no one is to stand in front or in line
with the brush. Loose bristles or wires will be
discharged during the run-in time.
c) Direct the discharge of the spinning wire
brush away from you. Small particles and tiny
wire fragments may be discharged at high velocity
during the use of these brushes and may become
imbedded in your skin.
4.5 Additional Safety Instructions
WARNING – Always wear protective
goggles.
Use elastic cushioning layers if they have been
supplied with the abrasive and if required.
Observe the specifications of the tool or accessory
manufacturer! Protect the discs from grease or
impacts!
Abrasives must be stored and handled with care in
accordance with the manufacturer's instructions.
Never use parting grinder discs for roughing work.
Do not apply pressure to the side of parting grinder
discs.
The workpiece must lay flat and be secured against
slipping, e.g. using clamps. Large workpieces must
be supported adequately.
Keep hands away from the rotating tool! Remove
swarf and similar material only when the machine is
at a standstill.
Prior to use, ensure that the coated abrasive is
properly fitted and secured. Run the tool in idling for
60 seconds in a safe position and bring to a stand-
still immediately if there are significant vibrations or
if other deficiencies are determined. If such a situa-
tion occurs, check the machine to determine the
cause.
Ensure that sparks produced during work do not
constitute a risk to the user or other personnel and
are not able to ignite inflammable substances.
Endangered areas must be protected with flame-
resistant covers. Make sure that fire-risk areas are
always provided with suitable fire extinguishers.
When working in dusty conditions, ensure that
ventilation openings are not blocked. If it becomes
necessary to remove dust, first disconnect the
power tool from the mains supply (use non-metallic
objects) and avoid damaging internal components.
Damaged, eccentric or vibrating tools must not be
used.
For safety reasons, always ensure the rubber
sleeve is fitted while you work (4).
Pull the plug out of the plug socket before any
adjustments, conversions or servicing are
performed.
During machining, of metals in
particular, conductive dust can form
deposits inside the machine. This can lead to the
transfer of electrical energy onto the machine
housing. This can mean a temporary danger of
electric shocks. This is why it is necessary when the
machine is running to blow compressed air through
the rear ventilation slots of the machine regularly,
frequently and thoroughly. The machine must be
held firmly in this case.
We recommend using a stationary extractor system
and connecting a residual current circuit-breaker
(FI) upstream. When the machine is shut down via
the FI circuit-breaker, it must be checked and
cleaned. For information on cleaning the motor, see
chapter 8. Cleaning.
Reduce dust exposure:
Some dust created by using this power tool
may contain chemicals known to cause
cancer, allergic reaction, respiratory disease, birth
defects or other reproductive harm. Some
examples of these chemicals are: Lead from lead-
based paints, crystalline silica from bricks and
cement and other masonry products, Arsenic and
chromium from chemically-treated lumber, hard
wood like oak or beech, Metals, Asbestos.
The risk from these exposures depends on how
long you or bystanders are being exposed.
Do not let particles enter the body.
To reduce your exposure to these chemicals: work
in a well ventilated area, and work with approved
safety equipment, such as dust masks that are
specially designed to filter out microscopic
particles.
Observe the relevant guidelines for your material,
staff, application and place of application (e.g.
occupational health and safety regulations,
disposal).
Collect the generated particles at the source, avoid
deposits in the surrounding area.
Use suitable accessories for special work (see
chapter 10.), thus less particles enter the
environment in an uncontrolled manner.
Use a suitable extraction unit.
Reduce dust exposure with the following measures:
- Do not direct the escaping particles and the
exhaust air stream at yourself or nearby persons
or on dust deposits.
