Cleaning
NOTICE Environmental damage due to polluted
water
Hydraulic oil and chisel paste are environmentally
harmful and must not penetrate the ground or
enter the water table or water supplies.
◆
Collect the water used for cleaning if it has
been contaminated by hydraulic oil and chisel
paste.
◆
Dispose of the water in accordance with the
applicable regulations to avoid environmental
hazards.
Every second hour
Regularly lubricate the working tool, the tool
retainer and the bushings.
Lubricating with a grease gun
WARNING Hot working tool during
operation and a period of time after use.
►
Avoid contact with the working 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 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.
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.
Central lubrication system
We recommend Epiroc'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.
Every week
◆
Clean the hydraulic breaker carefully.
◆
Check the wear bushing's wear and maximum
inner wear limits.
The wear bushing must be replaced when the
inner diameter (A) has reached its maximum
wear limit, see section "Wear limits" and
"Replacing the working tool bushing".
