Checking and reducing the gas pressure
1. Always use the gas hose (C) and the pressure
gauge (D) when checking the gas pressure.
2. Connect the gas hose to the pressure gauge.
3. Remove the plug from the charge valve (G).
4. Press the nozzle of the gas hose into the charge
valve and read the pressure.
5. Reduce the pressure by repeatedly inserting and re-
moving the nozzle.
NOTICE
Only the nozzle may be used to reduce the
pressure. Never use pins, screwdrivers or other pointed
instruments, as these can damage the charge valve.
7.4 Every second hour
Regularly lubricate the working tool, the tool retainer and
the bushings.
7.4.1 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 against the piston so that the
space between the piston and the working tool does
not fill with grease.
2. Lubricate the working tool's shank plentifully while
pressing the working tool against the surface to avoid
filling the cavity with grease. If the cavity is filled with
grease when the hydraulic breaker is started, the
lower seals may be damaged.
When the working tool shank is exposed to high pres-
sure and high temperatures a standard type of grease
will melt and run. To avoid this always use a genuine
working tool grease from your supplier.
7.5 Every day
n
Check the tool retainer and split pin.
n
Check that hoses, couplings and accumulator are in
a good condition.
n
Check that bolts and connections are free from dam-
age and properly tightened. See tightening torques in
the spare parts list.
n
Refill the central lubricating system.
7.6 Every week
n
Clean the hydraulic breaker carefully.
n
Check the wear bushing's wear and maximum inner
wear limits.
