To use as a vent (for vertical applications or temporary venting)

pull up on hex plug until ﬁ rst detent is reached (see Figure 5). This

is the vented position.

To use as a return-to-tank port, remove ﬂ ush plug from hex and

install compatible return line. Torque return line to 15-20 ft. lbs.

[20-27 Nm] in hex plug.

CAUTION: Pump reservoir must be vented using one

of the two vent options. Failure to do so may cause

cavitation and pump damage.

5.5 Mounting Pump

15000: Pump can be mounted horizontally or vertically. If

mounted vertically, position pump with hydraulic outlet port(s)

facing down.

15000 and 15020: The four holes in the bottom of the

reservoir should be used for bolting through the mounting surface

into the reservoir. Use the #10 x 5/8" fasteners included with

pump, or allow no more than 3/4" [19 mm] thread engagement

into reservoir.

CAUTION: When mounting the pump in the vertical

position, the vent screw must remain closed.

15040: The U-shaped mounting rails on the bottom of the

reservoir have four .26 in. [6,6 mm] holes for mounting.

5.6 Oil Level

Always check oil level with all cylinders or tools in the fully

retracted position. If they are advanced when the pump is ﬁ lled,

the reservoir will be over-ﬁ lled when they are retracted.

Use the low-level sight glass on the end of the pump to check the

oil level. When the pump is mounted horizontally, the reservoir

is full when oil is at the bottom of the ﬁ ll port. If oil is not visible,

then oil must be added. To add oil, remove Vent/Fill plug from

reservoir (See section 5.4b).

When the pump is mounted vertically, 15000 the oil level should

be checked periodically by removing the pump and placing it

on a horizontal surface.

NOTE: Prior to mounting the 15000 pump in the vertical position, oil

volume in the reservoir must be reduced to 127 in3 [2,1 L] prevent

leakage through the vent/ﬁ ll plug. See the speciﬁ cation table on page

2 for usable oil capacity in vertical position.

6.0 OPERATION

6.1 Oil Level

Check the oil level of pump and add oil if necessary (See

Installation section, step 5.6).

6.2 Venting Pump

Make sure the pump reservoir is vented (See Installation section,

step 5.4).

6.3 Treadle Operation

See ﬁ gure 6.

a) To Advance Cylinder: Depress the "PRESSURE" end of treadle

and the pump will start to pump hydraulic oil to the system.

b) To Hold The Cylinder Position: The pump will stop and hold

pressure when the treadle is in the free/neutral position (treadle is

not depressed in either "PRESSURE" or "RELEASE" positions.)

c) To Retract Cylinder: Depress the "RELEASE" end of the treadle

to retract cylinder. To stop the cylinder from retracting, release

the treadle and return it to the hold position.

6.4 Priming

Priming of the hydraulic pump is normally not required. If the

air motor runs very fast, but no hydraulic pressure is built, the

pump may have lost its prime. This pump can lose prime if it

is run completely out of oil or if an air bubble is trapped in the

pumping chamber. An air bubble could occur during shipment,

or when the shipping plug is removed while the pump is held in

the vertical (shipping plug up) position.

a) Place the pump on a ﬂ at, horizontal surface. Remove the

shipping plug only when in a horizontal position! Attach

an approved 10,000 psi rated hydraulic hose and cylinder

assembly to the hydraulic outlet 3/8" NPT port. Torque ﬁ ttings

to 65-75 ft.lbs. (88-102 Nm.)

b) Attach air supply to the 1/4" NPT swivel connection. Torque to

20-25 ft. Lbs (27-34 Nm.).

c) Fill pump with only high-quality hydraulic Oil, 32 cSt hydraulic oil.

d) Prime the pump with air pressure set to 30-40 psi. If air pressure

is different than 30-40 psi follow the procedure below:

e) ON MODELS WITH TREADLE: While holding the treadle down

ﬁ rmly in the RELEASE position, slowly depress the PRESSURE

button located under the toe of the treadle near the air supply

ﬁ tting. Try to get the air motor to operate one or two cycles

at a time. Slowly depressing the PRESSURE button will allow

you to "throttle" the inlet air pressure

f) Pressing the operating buttons in this manner effectively draws

oil through the intake tube to reﬁ ll the pressure chamber. You

may need to hold the treadle and "throttle" the PRESSURE

button for a few minutes to completely remove the air and

prime the pump models with an air pendant, hold "RET" button

down while cycling

g) ON MODELS WITH 4-WAY VALVES: Shift valve to neutral position,

press the treadle, and run the pump momentarily several times.

h) On models with an air pendant, hold "RET" button down while

cycling "ADV" button momentarily several times.

i) To verify that the pump is primed, operate as normal with

cylinder attached. If cylinder does not advance, repeat step

6.4g or 6.4h.

7.0 MAINTENANCE

7.1 Maintaining Proper Oil Level

Check the oil level of the pump prior to start-up, and add only

high-quality hydraulic oil, if necessary, by removing the vent/ﬁ ll

plug (refer to Installation section, step 5.6).

7.2 Cleaning The Mufﬂ er

Clean the mufﬂ er every 250 hours, or more frequently if pump

is used in dirty environments. First remove 2 shoulder bolts (A)

and treadle (B). See Figure 7. To expose the mufﬂ er, remove

2 screws (C) holding down mufﬂ er plate. See Figure 8. Wash

mufﬂ er element in soapy water, dry, and reassemble, installing

screws hand tight.

7.3 Changing The Oil

Change the oil every 250 hours. The vent/ﬁ ll plug serves as a

drain plug for use in changing oil. Reﬁ ll pump with only high-

quality hydraulic oil. Dispose of used oil properly.

7.4 Cleaning The Air Inlet Filter

Remove the swivel air connector by removing the two cap screws

and pulling air ﬁ lter out of cavity. Using an air nozzle blow debris

off ﬁ lter. (Always use proper eye protection). Re-install ﬁ lter and

swivel connector. Torque cap screws to 16-18 in.lbs [1,8-2,0 Nm].
