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.

Safety and operating instructions
Checking for wear
1. Check the wear in the chuck bushing using the
Atlas Copco (3091 0038 00) gauge (22 mm).
If the wear limit has been exceeded, the drill steel
shank will wear more quickly, or become
deformed. This will lead to stoppages and
increased drill-steel consumption.
2. Check the tightness of the side-bolt nuts
(A).Tighten to a torque of 130 Nm.
3. Check the rock drill's connection to the pusher
leg.
4. Check the hoses, couplings and controls for
leakage and damage.
