Hammer Safety Warnings
Wear ear protectors. Exposure to noise can cause
•
hearing loss.
Use auxiliary handle(s) if supplied with the tool. Loss of
•
control can cause personal injury.
Hold the power tool by insulated gripping surfaces,
•
when performing an operation where the cutting
accessory may contact hidden wiring. Cutting accessory
contacting a "live" wire may make exposed metal parts of the
power tool "live" and could give the operator an electric shock.
Safety Instructions When Using Long
Drill Bits with Rotary Hammers
Always start drilling at low speed and with the bit tip
•
in contact with the workpiece. At higher speeds, the bit is
likely to bend if allowed to rotate freely without contacting the
workpiece, resulting in personal injury.
Apply pressure only in direct line with the bit and do not
•
apply excessive pressure. Bits can bend causing breakage or
loss of control, resulting in personal injury.
Additional Safety Instructions for
Rotary Hammer Drills
Use clamps or other practical way to secure and support
•
the workpiece to a stable platform. Holding the work by
hand or against your body is unstable and may lead to loss
of control.
Wear safety goggles or other eye protection. Hammering
•
operations cause chips to fly. Flying particles can cause
permanent eye damage. Wear a dust mask or respirator
for applications that generate dust. Ear protection may be
required for most applications.
Keep a firm grip on the tool at all times. Do not attempt
•
to operate this tool without holding it with both hands. It
is recommended that the side handle be used at all times.
Operating this tool with one hand will result in loss of control.
Breaking through or encountering hard materials such as
re-bar may be hazardous as well. Tighten the side handle
securely before use.
Do not operate this tool for long periods of time.
•
Vibration caused by hammer action may be harmful to your
hands and arms. Use gloves to provide extra cushion and limit
exposure by taking frequent rest periods.
Do not recondition bits yourself. It should be done by an
•
authorized specialist. Improperly reconditioned bits could
cause injury.
Wear gloves when operating tool or changing bits.
•
Accessible metal parts on the tool and bits may get extremely
hot during operation. Small bits of broken material may
damage bare hands.
Never lay the tool down until the bit has come to a
•
complete stop. Moving bits could cause injury.
Do not strike jammed bits with a hammer to dislodge
•
them. Fragments of metal or material chips could dislodge
and cause injury.
When working above the floor, make sure that the area
•
below is clear. Falling parts can cause injuries to bystanders.
Reducing of Dust Exposure
Before starting work, check the hazard class of the dust that will
be produced when working.

WARNING: Dust can be harmful to health. Touching or
breathing of some dust created during the work process
by using a power tool and other construction activities
contains chemicals, mineral or particles known to
cause respiratory infections, allergic reactions, cancer,
birth defects or other reproductive harm of the user or
bystanders.
• Such dusts can be generated, for example, when working
- on hardwoods such as beech or oak, lead based paint, on
concrete, masonry or stones containing quartz.
• Material containing asbestos may be handled only by
specialists.
• Observe the relevant regulations in your country for the
materials to be worked on.
• Use a dust extractor or extraction system with an officially
approved protection class in compliance with the locally
applicable dust protection regulations and suitable for the
material to be worked on.
• Capture the resulting dust particles directly at the source and
avoid deposits in the surrounding area. Use suitable extraction
accessories for this purpose.
additional measures:
ʵ Make sure that the workplace is well ventilated.
ʵ Wear a respirator appropriate for the type of dust
generated.

Residual Risks

The following risks are inherent to the use of rotary hammers:
• Injuries caused by touching the rotating parts or hot parts of the tool.
In spite of the application of the relevant safety regulations
and the implementation of safety devices, certain residual risks
cannot be avoided. These are:
• Impairment of hearing.
• Risk of squeezing fingers when changing the accessory.
• Health hazards caused by breathing dust developed when
working in concrete and/or masonry.
• Risk of personal injury due to flying particles.
