When taking a break

♦ During all breaks you must place the machine in
such a way that there is no risk for it to be
unintentionally started. Make sure to place the
machine on the ground, so that it can not fall.
♦ In the event of a longer break or when leaving the
workplace: Switch off the power supply and then
bleed the machine by activating the start and stop
device.

Maintenance

Regular maintenance is a basic requirement for the
continued safe and efficient use of the machine.
Follow the maintenance instructions carefully.
♦ Before starting maintenance on the machine, clean
it in order to avoid exposure to hazard substances.
See "Dust and fume hazards"
♦ Use only authorised parts. Any damage or
malfunction caused by the use of unauthorised
parts is not covered by warranty or product liability.
♦ When cleaning mechanical parts with solvent,
comply with appropriate health and safety
regulations and ensure there is satisfactory
ventilation.
♦ For major service to the machine, contact your
nearest authorised workshop.
♦ After each service, check that the machine's
vibration level is normal. If not, contact your
nearest authorised workshop.
Differences between original
parts and pattern parts
When buying a part, the first thing to do is to verify
that the part is an Atlas Copco part. Most parts can
be identified.

Safety and operating instructions
Rock drill parts are normally marked with a part
number and the Atlas Copco identity mark which is
a circle with a rock drill. In a few cases the part is
marked either with the circle only or the part number
only.
Rubber and plastic parts are not normally marked.
Competitors that copy our parts often mark major,
expensive parts. Some parts have only the part
number, but some of them also have an identity mark
in the form of the initials of the manufacturer's name.
Part numbers on the pattern parts are mostly
stamped by hand which results in irregularities. The
part numbers stamped by Atlas Copco are regular
and the individual figures are the same size. In
addition the depth of the figures and the spacing
between the figures in each group are the same.

Every day

Before undertaking any maintenance or changing
the insertion tool on pneumatic machines, always
switch off the air supply and bleed the machine by
depressing the start and stop device then disconnect
the air hose from the machine.
Clean and inspect the machine and its functions
♦
each day before the work commences.
Conduct a general inspection for leaks and
♦
damage.
Check that the air inlet nipple is tightened and that
♦
the claw coupling is free from damage.
Check the function of the throttle handle. Make
♦
sure that it moves freely up and down.
♦ Check the function of the retainer. Make sure that
it locks the drill steel.
♦ Change damaged parts immediately.
♦ Replace worn components in good time.
♦ Check the through bolts of the machine. Make
sure that they are tightened.
♦ If the machine is equipped with a silencer, check
for damage.
