MSD SABER SERIES SHEARS
HYDRAULIC SYSTEM
MAINTENANCE
Use the following instructions to safely perform
hydraulic checks and maintenance on the shear.
1.
Always relieve all excavator hydraulic pressure
before working on any hydraulic component. Relieve
hydraulic pressure before working on the machine
by working the controls in all directions with the
engine off.
2.
In order to test the hydraulic system, a diagnostic
fi tting will need to be installed into the shear hydrau-
lic manifold block. To do this, shut off the excavator
and relieve the system pressure. Make sure the sys-
tem pressure is at zero (0) psi and remove the dash-
4 (1/ 4") O-ring boss plug from the diagnostic port on
the hydraulic manifold block. Replace this plug with
a diagnostic fi tting for your test gauge. Maintaining
proper operating pressure will result in the best cut-
ting performance. This is also a quick check to make
sure that the excavator is performing up to specifi ca-
tions.
3.
Check all hydraulic components (split fl anges,
hoses, fi ttings, mounting hardware, etc.) every 80
hours.
4.
Have the shear cylinder seals replaced by an au-
thorized Stanley LaBounty dealer every 2,000 hours.
5.
Whenever hydraulic lines are disconnected,
hoses must be capped and ports must be plugged
to prevent contamination of the hydraulic system.
Relieve pressure before disconnecting hydraulic
lines. Tighten all connections before applying
pressure. Keep hands and body away from pin
holes and nozzles, which can eject fl uids under
high pressure. Use a piece of cardboard to search
for leaks. Escaping fl uid under pressure can
penetrate the skin and cause serious injury.
If ANY fl uid is injected into the skin, seek
immediate medical attention.
NEVER adjust pressure relief valves to get
higher operating pressures. The manufacturer’s
recommended pressures give the safest
performance with the longest life.
