Breaking under water

Hydraulic breakers can be used for operating under
water.
When operating under water the hydraulic breaker
must be fed with compressed air to keep the area
between the piston and the working tool free from
water. If the area between the piston and the working
tool gets filled with water, it may penetrate into the
hydraulic oil system when the hydraulic breaker is
started.
The air pressure should be 1.5–2 bar at the air inlet
on the breaker and the air consumption is found in
"Technical data". Suitable air hose is a ¼" hydraulic
hose with JIC connection. Contact your nearest
authorised workshop for further instructions.

Maintenance

It is essential that regular maintenance is performed
to maintain the breakers maximum efficiency.
Equipment that is insufficiently maintained can be
dangerous for both the operator and persons near
the breaker. Make sure that regular maintenance
routines with lubrication are followed to keep the
equipment safe and efficient.

Every second hour

Regularly lubricate the working tool, tool retainers
and the bushings, with Atlas Copco Tool chisel paste.

Lubricating with a grease gun

WARNING Hot working tool during operation
and a period of time after use.
► Avoid contact with the working tool.

Safety and operating instructions
CAUTION Skin eczema
Grease can cause eczema when it comes in contact
with the skin.
► Avoid getting grease on your hands.
1. Push the tool all the way into the breaker up to
the stop (A). Otherwise the space between the
top of the tool and the breaker will be filled up
with grease.
A
2. Lubricate the working tool's shank plentifully
during all upward operations. The bushing and
the working tool must be lubricated so frequently
that dirt cannot penetrate into the hydraulic
breaker.
When the tool shank is exposed to high pressure
and high temperatures a standard type of grease will
melt and run. To avoid this always use Atlas Copco
Tool chisel paste.

Central lubrication system

We recommend Atlas Copco central lubrication
system. When this system is fitted on the carrier,
grease is pumped continuously from a lubrication
container on the carrier to the breaker when the
breaker is activated. This increases the life of the
tool bushings and working tools considerably.

Every day

1. Check tool retainers and lock pin.
2. Check that hoses, couplings and accumulator
are in a good condition.
3. Check that bolts and connections are free from
damage and properly tightened. See tightening
torques in the spare parts list.
4. Refill the central lubricating system.
