Diamond Products CB240 - Manual (Page 29)

OPERATING DRIVEN
EQUIPMENT
The operator must know the hydraulic
requirements and limitations of the driven
equipment and the appropriate
adjustments must be made on the controls.
The introduction of other control devices
may cause system heating or may render
the system inoperative.
IMPORTANT: This power unit is
equipped with a positive displacement
gear pump. All tools must be equipped
with a control valve that allows flow
directly to return ports when not in use.
Blocking oil flow or abruptly
disconnecting the tool can send flow
over relief and potentially overheat the
system.
Instructions supplied with the driven
equipment must be followed to ensure
correct connection and operation of each
individual piece of equipment. Equipment
supplied by Diamond Products will be
capable of being connected correctly and
will be compatible with this power unit,
providing neither has been modified from
original factory configuration. With
equipment of other manufacturers, it will be
necessary to determine the following:
 Correct direction of flow through the
equipment.
 Correct pressure and flow required by
the equipment.
 Compatibility of any valves or circuitry
and quick disconnects. Some hand-
held equipment uses a trigger control,
which is operated frequently. These
valves must be of the open center type
for correct operation.
IMPORTANT: The quick disconnects
must be clean when connecting hoses
and devices. Dirty connections may
result in contamination and premature
failure of system or tool components.
MAINTENANCE
INSTRUCTIONS
 Oil Filter: change the filter when
indicated by the gage at the filter.
 Oil Change: establishing an oil analysis
program is the preferred method of
determining oil condition and when to
change it. If the oil is kept clean, dry,
and operated at moderate
temperatures, it can last for several
years. With no analysis program an oil
change every 200 hours is
recommended. See the section
Hydraulic Fluid for specifications. A ½”
pipe thread oil drain port is at the
bottom of the hydraulic tank.
 Gas Engine Oil: Change engine oil and
filter and perform other routine
maintenance as recommended in the
engine operation manual.
 Inspect hoses, couplings, and fittings
daily for leaks, tighten as required.
Clean quick disconnects frequently.
Replace any leaking or defective
components immediately.
 Check hydraulic oil level daily. Fill tank
to upper end of sight tube with unit off.
 Grease the wheel bearings annually.
