Safety and operating instructions
Warning
Changing the working tool while the machine is
running may cause serious injury.
► Before changing the tool always stop the machine.
► Never grab or touch a rotating drill steel.
Warning
A compressed air hose that comes loose can lash
around and cause personal injury or death.
To reduce risks:
► Check that the compressed air hose and the
connections are not damaged.
► Check that all compressed air connections are
properly attached.
► Never attempt to disconnect a compressed air
hose that is pressurized. First switch off the
compressed air at the compressor and then bleed
the machine by activating the start and stop
device.
Warning
If the drill steel gets caught during operation, the
whole machine will start to rotate if you lose your grip
on it. This unexpected rotation of the entire machine
may cause serious injury.
► Stand firmly and always hold onto the machine
with both hands.
► Make sure that the handle is clean and free
from grease and oil.
► Never drill in an old hole.
Warning
There is a risk of items getting dragged into or caught
by a rotating drill steel. This may cause serious injury.
► Never grab or touch a rotating drill steel.
► Avoid wearing clothing that may get caught.
If you have long hair, cover it with a hair net.

Explosion and fire hazard

Danger
If the machine comes in contact with an explosive, an
explosion may occur. Explosions may cause serious
injury or death.
To reduce the risk of explosion:
► Never use the equipment to drill near any
explosives, including dynamite or other explosives
in the rock.
► Make sure that there are no explosives in the rock.
► Never drill in an old hole.
Warning
Drilling and working with certain materials can cause
sparks, which may ignite explosive gases and cause
explosions. Explosions may cause serious injury or
death.
To reduce such risk of explosion:
► Never operate the machine in any explosive
environment.
► Do not use the machine near flammable materials,
fumes or dust.
► Make sure that there are no undetected sources of
gas.
Electrical/Concealed object
hazards
Danger
The machine is not electrically insulated. If the
machine comes into contact with electricity, serious
injuries or death may result.
► To reduce the risk of such injury or death, never
operate the machine near any electric wire or other
source of electricity.
► Make sure that there are no concealed wires or
other sources of electricity.
Warning
During drilling, concealed wires and pipes constitute a
danger that can result in serious injury.
► Before you start drilling, check the composition of
the material you are to work on.
► Watch out for concealed cables and pipes e.g.
electricity, telephone, water, gas and sewage lines
etc.
► If the tool seems to have hit a concealed object,
switch off the machine immediately.
► Make sure that there is no danger before
continuing.
