Atlas Copco SB 52

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 chisel paste.
Lubricating with a grease gun
WARNING Hot insertion tool during operation
and a period of time after use.
► Avoid contact with the insertion tool.
WARNING Hot hydraulic breaker during
operation and a period of time after use.
► Avoid contact with the hydraulic breaker.
CAUTION Skin eczema
Grease can cause eczema if it comes in contact with
the skin.
► Avoid getting grease on your hands. Wash
thoroughly after contact.
1. Press the insertion tool all the way into the
breaker up to the stop (A). Otherwise the space
between the top of the insertion tool and the
piston will be filled with grease, and damage can
occur to seals, piston, and cylinder.

2. Lubricate the insertion tool's shank plentifully
during all upward operations. The bushing and
the insertion tool must be lubricated so frequently
that dirt cannot penetrate into the hydraulic
breaker.
When the insertion tool is exposed to high pressure
and high temperatures a standard type of grease will
melt and run. To avoid this always use Atlas Copco
chisel paste.
Central lubrication system
We recommend Atlas Copco's central lubrication
system. When this system is fitted on the carrier,
grease is pumped continuously from a lubrication
container on the carrier to the hydraulic breaker when
the hydraulic breaker is activated. This increases the
life of the tool bushings and working tools
considerably.
Every day
♦
Check tool retainers and lock pins for damage,
change if necessary.
♦
Check that hoses, couplings, and accumulator are
in a good condition, change if necessary.
♦
Check that bolts and connections are free from
damage and properly tightened, change if
damaged. See tightening torques in the spare
parts list.
♦
Refill the central lubricating system.
♦
Check that wear plate and bolts are free from
damage, change if necessary.
