Stopping the rock drill

1. Switch of flushing when drilling is complete.
2. Switch off the impact mechanism or reduce
percussion, before reversing the feeding direction
of the rock drill.

Operating

Drilling

♦ Use protective shoes, gloves, helmet, ear
protectors and impact resistant eye protection with
side protection.
♦ Hold the inserted tool firmly against the work
surface before starting the machine.

When taking a break

♦ If the rock drill has been converted to water
flushing, water pressure needs to be shut off
before air pressure. Run the rock drill for a few
seconds to clean out water and moisture after the
water has been shut off.

Regular maintenance is a basic requirement for the
continued safe and efficient use of the machine.
Follow the maintenance instructions carefully.

it in order to avoid exposure to hazardous
substances. See "Dust and fume hazards"

♦ When cleaning mechanical parts with solvent,
comply with appropriate health and safety
regulations and ensure there is satisfactory

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.
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 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.
