•
If the machine blocks, higher reaction torques can occur. Blocking can be caused by:
overload, tilting of the drill bit in the work piece or when penetrating the material to be
drilled. Do not let the drill bit rumble on the work piece, as this will most likely increase the
vibration. When drilling through-holes, reduce the contact pressure shortly before the drill bit
penetrates the material (for thin walled work pieces there is the risk that the drill hitches the
work piece and lifts it.)
•
It is possible that the drill bit keeps on running after the machine has been switched off. Wait
until it stops and deposit the hand-held machine in a secure position.
•
Never stop the drill chuck or the drill bit by hand.
SAFETY INSTRUCTIONS FOR PREVENTION
CAUTION – Loose clothing, personal jewellery (e.g. necklace), scarves/ ties, long
hair or gloves can get caught up in the machine tool or accessories and thus cause
severe injuries (lack of breath by throttling, abrasions, skin injuries and/ or cuts and
lacerations).
Wear suitable, close fitting work clothing!
Wear a hair net, if you have long hair.
When handling the machine, jewellery, necklaces, etc. have to be removed or are
forbidden, respectively.
SAFETY INSTRUCTIONS FOR PREVENTION OF NOISE HAZARDS
Always wear hearing protection (EN 352) – This refers to the operator, as well as
to any other person within the vicinity of the machine. Observe the instructions of
the employer and of the professional association.
High noise levels during operation can cause permanent hearing problems such as
tinnitus (ringing, buzzing, whistling or humming in the ears), hardness of hearing or
even deafness.
·
Before starting work, ensure that the provided, respectively the factory-made, sound
absorbers are mounted and in proper condition.
·
If possible, use sound absorbing material, in order to avoid ringing noise at the work pieces.
SAFETY INSTRUCTIONS FOR PREVENTION OF VIBRATION HAZARDS
Vibrations can cause disabling damage to the nerves and blood supply of the hands and
arms.
·
Wear warm clothing and keep your hands warm and dry when working in cold conditions.
Exercise hands and fingers regularly.
·
Do not hold the machine tool with the free hand
·
Use stands and/or weight balancers, if possible.
·
When using a support (e.g. stand) make sure the machine is securely fixed. If no support is
