4. Connect the pressure gauge to the HP-
accumulator via the pressure line »P«.
5. Close the tank line »T«.
You need an assistant to monitor the pressure
gauge.
WARNING Injury by impact
A sudden movement of the carrier may cause
your assistant to be hit and injured by the boom
or the hydraulic attachment.
►
Do not move the boom while your assistant
is within the danger zone.
►
Always keep sight of your assistant.
6. Switch on the hydraulic breaker at the lowest
possible engine rpm and mode level.
7. Switch off the hydraulic breaker as soon as
your assistant indicates that the operating
pressure (180 bar) is reached.
8. Open the tank line »T« a little and slowly
release pressure.
9. Watch the pressure gauge during the release
procedure. As soon as the gas pressure in the
HP-accumulator is reached, the indicator stops
shortly and then drops sharply to zero.
10. Refilling is required if the gas pressure is lower
than 50 bar. Refilling must be performed by an
authorized person. Contact the Atlas Copco
Customer Center/dealer in your area.
Checking the hydraulic lines
◆
Before starting your work shift, always carry out
a visual check of all lines (pipes and hoses)
from the pump to the hydraulic attachment and
from there to the tank.
◆
Tighten any loose screw connections or hose
clamps.
◆
Replace damaged pipes and/or hoses.
Checking and cleaning the
hydraulic oil filter
An oil filter must be integrated in the tank line of
the hydraulic system. The maximum mesh width
allowed for the oil filter is 50 microns; it must have
a magnetic separator.
◆
Replace the oil filter cartridges after the first 50
operating hours.
◆
Check the oil filter every 500 operating hours
and replace as required.
Checking the adapter plate
and the breaker box for
cracks and/or wear
◆
Check the adapter plate and the breaker box for
cracks every week.
◆
Have rework activities or repairs carried out in
time to avoid major damage.
◆
The wear rails (A) in the lower section of the
breaker box can be replaced as required.
Please consult the Atlas Copco Customer
Center/dealer in your area.
