Checking hydraulic lines
♦
Secure the carrier such that it cannot move
unexpectedly.
♦
Perform a visual inspection of all lines (pipes and
hoses) from the pump to the hydraulic attachment
and back to the tank, before starting work.
♦
Tighten loose bolted connections and hose clamps
to the torque required (see Chapter
Bolted
connections / tightening torques
).
♦
Replace damaged pipes and/or hoses.
Checking bolted connections
♦
Secure the carrier such that it cannot move
unexpectedly.
♦
Check all bolted connections regularly for tight fit
(see Chapter
Bolted connections / tightening
torques
).
♦
Tighten loose bolted connections and hose clamps
to the torque required (see Chapter
Bolted
connections / tightening torques
).
Checking the adapter plate
bolts for wear
♦
Carry out this visual check whenever the hydraulic
attachment has been removed from the carrier.
♦
Check the adapter plate bolts for excessive wear
such as cracks, pitting or severe erosion.
♦
Rework or replace worn bolts.
Checking and cleaning the
hydraulic oil filter of the carrier
An oil filter must be integrated in the return circuit of
the hydraulic system. The maximum mesh width
allowed for the oil filter is 50 microns; it must have a
magnetic separator.
♦
Secure the carrier such that it cannot move
unexpectedly.
♦
Change the oil filter cartridge after the first 50
operating hours.
♦
Check the oil filter
every
500 operating hours and
replace it is necessary.
Changing the oil in the
PermanentLube system
The oil in the PermanentLube system must be
changed once a year.
♦
Place timber support blocks on an oil pan.
♦
Position the hydraulic compactor on timber support
blocks.
NOTICE
Environmental damage due to
consumables
Motor oil is environmentally harmful and must not
penetrate the ground or enter water table or water
supplies.
►
Collect any dumped waste oil.
►
Ensure that containers filled with motor oil cannot
topple over and flow out, so that your working area
will not be polluted.
►
Observe all Safety and environmental protection
provisions when handling motor oil.

♦
Remove the air breather valve (A) and drain plug
with seal (B) from rotor housing.
♦
Tip the rotor housing and rest it on its side, so that
the oil runs out.
♦
Restore the rotor housing to its upright position.
♦
Fit the drain plug and seal (B) back in the rotor
housing. Required tightening torque see chapter
Bolt connections/Tightening torques
.
♦
Remove the oil level indicating plug (C) and fill
with new oil via hole (A) until oil trickles from hole
(C). Use Atlas Copco Cobra & Compactor
Impact-Oil, part number 9234 0012 03.
