instructions given in the operating instructions for
the Hilti power tool used. Failure to observe the
instructions could lead to serious injury.
5.1 Work area safety
Keep the work area tidy. Any objects which may
cause injury should be removed from the area.
Untidiness at the workplace can lead to accidents.
5.2 Electrical safety
a) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will
reduce risk of electric shock.

not n use. Do not allow persons unfamiliar with
the appliance or these instructions to operate it.
Appliances are dangerous in the hands of untrained
users.
d) Disconnect the supply cord plug from the power
outlet before maintenance.
e) When operating an appliance outdoors, use an
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of
electric shock.
f) Check the appliance’s supply cord at regular
intervals and have it replaced by a qualified specialist if found to be damaged. If the appliance’s
en
11
supply cord is damaged it must be replaced with
a specially-prepared supply cord available from
Hilti Customer Service. Check extension cords
at regular intervals and replace them if found
to be damaged. Do not touch the supply cord in
the event of it suffering damage while working.
Disconnect the supply cord plug from the power
en
outlet. Damaged supply cords present a risk of
electric shock.

area while the appliance is in use. Distractions
can cause you to lose control.
b) Children should be supervised to ensure that
they don’t play with the appliance.
c) Stay alert, watch what you are doing and use
common sense when operating the appliance.
Do not use the appliance while tired or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating appliances
may result in serious personal injury.
d) Avoid unusual body positions. Make sure you
work from a safe stance and stay in balance at
all times.

the appliance for purposes for which it was not
intended. Use it only as directed and when in
faultless condition.
c) Do not abuse the supply cord and/or the hose.
Never use the supply cord or hose to carry or
pull the appliance and do not pull the supply
cord when unplugging. Damaged supply cords
increase the risk of electric shock.
d) Keep the supply cord and hose away from heat,
oil, sharp edges or moving parts.
e) Check the appliance and its accessories for any
damage. Guards, safety devices and any slightly
damaged parts must be checked carefully to ensure that they function faultlessly and as intended. Check that moving parts function correctly
without sticking and that no parts are damaged.
