7.1 Cleaning
NOTICE
Environmental damage due to polluted water
Hydraulic oil and chisel paste are environmentally harm-
ful and must not penetrate the ground or enter the water
table or water supplies.
u
Collect the water used for cleaning if it has been con-
taminated by hydraulic oil and chisel paste.
u
Dispose of the water in accordance with the applica-
ble regulations to avoid environmental hazards.
7.2 Every second hour
Regularly lubricate the working tool, the tool retainer and
the bushings.
7.2.1 Lubricating with a grease gun
WARNING
Hot working tool during operation and
a period of time after use
u
Avoid contact with the working tool.
WARNING
Hot hydraulic breaker during operation
and a period of time after use
u
Avoid contact with the hydraulic breaker.
CAUTION
Skin eczema
Grease can cause eczema if it comes in contact with the
skin.
u
Avoid getting grease on your hands. Wash thor-
oughly after contact.
1. Press the working tool all the way into the breaker up
to the stop (A). Otherwise the space between the top
of the working tool and the piston will be filled with
grease, and damage can occur to seals, piston, and
cylinder.
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 working tool is exposed to high pressure and
high temperatures a standard type of grease will melt
and run. To avoid this always use Epiroc chisel paste.
7.2.2 Automatic lubrication
We recommend ContiLube™ II. This increases the life of
the tool bushings and working tools considerably.
7.3 Every day
n
Check tool retainers and lock pins for damage,
change if necessary.
n
Check that hoses, couplings, and accumulator are in
a good condition, change if necessary.
n
Check that bolts and connections are free from dam-
age and properly tightened, change if damaged. See
tightening torques in the spare parts list.
n
Refill the central lubricating system.
n
Check that wear plate and bolts are free from dam-
age, change if necessary.
7.3.1 Change wear plate and bolts
1. Detach the breaker from the carrier and position the
breaker in a safe way.
2. Remove the bolts.
3. Remove the wear plate and the O-rings. Do not re-
move the bushing.
4. Mount new O-rings, wear plate, and bolts. Use Moly-
cote
®
on the bolts. (Molykote is a registered trade-
mark of Dow Corning Corporation)
5. Tighten the bolts, use tightening torque 180 Nm
(133 ft lbs).
7.4 Every week
n
Clean the hydraulic breaker carefully.
n
Check the wear bushing's wear and maximum inner
wear limits.
