Operation
All pumps are factory set at 350 psi (24 bar)
working inlet hydraulic pressure with a flow
rate of 2.5 gal./min. (9.5 l/min). Do not
change the settings for the pump until
after the start up procedure.
1 Shut off the material supply line valve.
2 Turn on the hydraulic pressure.
3 Energize the solenoid on/off valve.
4 Prime the pump by slowly opening the
shut-off lubricant supply line valve. Make
sure that all air has been expelled from
the pump and even lubricant flow is
achieved.
5 Adjust the pump pressure and flow to the
desired application requirements. See
Pressure and flow control valve adjust-
ment for instructions to adjust pressure
and flow, Do not exceed pump operating
pressure of 450 psi (32 bar).
6 Always use the lowest pump output pres-
sure and hydraulic fluid flow to obtain the
desired results. This will reduce the pump
wear.
Do not exceed maximum operating
temperature of the hydraulic uid
(250 ºF (121º C)) . Never allow the pump
to run dry of lubricant. A dry pump
quickly speeds up, creating friction
heat, which can damage the seals.
Monitor the supply lubricant level and
rell when necessary.
CAUTION
Setting the pump
manifold pressure and
flow controls
The pressure must first be adjusted to
insure the desired flow setting is achieved.
Pressure control valve
adjustment
• With hydraulic pressure applied, stop the
pump by turning the flow control clock-
wise until completely closed.
• Loosen the lock nut on the pressure con-
trol by turning the nut counterclockwise.
• Turn the valve stem counterclockwise
until it no longer turns. The valve stem
will unscrew until it reaches the stop.
It will not come off. This is the minimum
pressure setting, which is about 170 psi
(12 bar).
• With the pump stalled against pressure,
turn the pressure control valve stem
clockwise until the desired pressure is
attained on the manifold pressure gage.
Do not exceed 450 psi (31 bar). A pres-
sure of 350 psi (24 bar) is recommended.
• Tighten the lock nut by turning clockwise.
Flow Control Valve
Adjustment
• Loosen the lock nut on the flow control
valve by turning the nut
counterclockwise.
• Adjust the flow by turning the valve stem
clockwise to reduce the flow and coun-
terclockwise to increase it.
• The flow control valve can be turned in
until the valve is completely closed, and
out to adjust pump speed.
• Recommended setting -
1
/4 to
1
/2 open.
• After adjusting the flow to the desired
setting, tighten the lock nut by turning it
clockwise († chart, page 20).
Crankcase oil service
interval
recommendations
• Check the oil level after every 750 hours
of machine operation, or every month.
• Change the oil after every 2,000 hours of
machine operation or every year.
• Use SAE 10W30 motor oil in all units
used in an ambient temperature between
–40 to 150 °F (–40 to 66 °C). For ambient
temperatures between –70 to 50 °F
(–56 to 10 °C), use Mobil Aero HFA Low
Temperature oil.
• Oil level should be at dot on dipstick (mid-
dle of crankshaft) using 10W30 motor oil
(15 oz. (443 cm³)).
