How To Operate - Atlas Copco SBC Serie Instrucciones Para El Operario

• Never attempt to sharpen the chisel through for-
ging. Work the chisel only by milling, grinding or
turning. Use suitable alloy steel tools.
• Fig. 1 shows the location of the hammer's
CE-plate on which the serial no. is given. On SBC
hammers the serial no. is also stamped on the
adapter plate surface, and on HBC hammers on
the return end of the cylinder.
• Check and follow the carrier's instructions for
changing of oil filters. The filter should usually be
changed more often when the hammer is in use.
• The hammer is a tool intended for demolition. It
should not be used for lifting or prizing.
Installation
!
WARNING
To avoid accidents, the hammer should be
secured against the carrier with chain.
• Install the hammer as per directions in the Instal-
lation Manual 9851 6090 01.
Contact Atlas Copco for directions.
• To ensure that the accumulator and hammer are
not overloaded, a separate pressure relief valve
should be installed, see fig. 2. It is set at a value
of 30 bar over the hammer's maximum working
pressure. If the carrier's hammer circuit is already
equipped with a pressure limiting valve, no extra
valve is necessary.
• Hammer working pressure. See Technical Data.
The pressure is set with the help of a pressure
gauge while the hammer is in operation, fig 3.

How to operate

!
CAUTION
Always run the hammer at the correct wor-
king pressure. See Techical Data. If the max.
working pressure of the hammer is excee-
ded this may overload the accumulator and
cause damage.
• Read the Operation Manual 9851 1859 02 for
suggestions on how the hammer may be used.
• For operation of the SBC hammers in a hot envi-
ronment it is necessary to exchange the plastic
wedge securing the chisel locking device as per
information in the spare parts list.
• For operation under water the hammer must be
filled with compressed air before it is submerged.
Any water in the space between the piston and
the chisel will destroy the piston seal when the
hammer is started. Contact Atlas Copco for in-
structions.
• Avoid running idle as this causes excessive wear
on chisel and chiselholder.
• Do not pry using the chisel.
Lubrication
Hand lubrication with a grease gun
Lubricate the chisel shank generously every other
hour with high-temperature grease such as
Atlas Copco Tool shank grease. This also lubricates
the bushings and chisel holders.
!
WARNING
When lubricating the chisel by hand, the car-
rier's engine should be switched off to avoid
risk of accidents.
On lubrication, the chisel must be pressed against
the hammer piston so that the space between the
piston and the chisel does not fill with grease (Fig. 6)
For all overhead work, the bushing and chisel must
be lubricated often enough to ensure that dirt does
not penetrate into the hammer.
Central lubrication
We recommend fitting the Atlas Copco central lubri-
cation system (not HBC 6000).
Ordering number:
Fill the lubricator via the lubrication nipple. With cen-
tral lubrication, the hammer is continuously lubrica-
ted, which greatly reduced wear on the bushings and
chisel.

Grease cartridge
Grease pot
Maintenance
Daily:
• Check chisel holder and locking pins.
• Check shock absorber and buffers.
• Check that hoses and couplings are in good con-
dition.
• Check that the adapter plate bolts are sound and
have not worked loose.
• Top up the central lubrication system.
Weekly:
• Clean the hammer thoroughly
