WARNING
Hand/Foot Operated
Maximum Capacity: 10,000 PSI
Before operating the hydraulic pump, all hose
connections must be tightened with proper tools.
Do not over-tighten. Connections need only be
tightened securely and leak-free. Over-tightening
may cause premature thread failure or may cause
high-pressure fittings to split at pressures lower
than their rated capacities
Should a hydraulic hose ever rupture, burst, or need
to be disconnected, immediately shut off the pump
and shift the control valve twice to release all pressure.
Never attempt to grasp a leaking hose under pressure
with your hands. The force of escaping hydraulic fluid
could cause serious injury.
Do not subject the hose to potential hazard such as fire,
extreme heat or cold, sharp surfaces, or heavy impact.
Do not allow the hose to kink, twist, curl, or bend so
tightly that the oil flow within the hose is blocked or
reduced. Periodically inspect the hose for wear because
any of these conditions can damage the hose and
possibly result in personal injury.
Do not use the hose to move attached equipment.
Stress may damage hose and possibly cause personal
injury.
Hose material and coupler seals must be compatible
with the hydraulic fluid used. Hoses must not encounter
corrosive materials such as creosote-impregnated
objects and some paints. Consult the manufacturer
before painting a hose.
Never paint the couplers. Hose deterioration due to
corrosive materials may result in possible personal injury
Do not exceed the PSI hydraulic rating noted
on the pump nameplate or tamper with the
internal high-pressure relief valve.
Creating pressure beyond rated capacities
may result in personal injury.
Before replenishing the oil level, retract the
system to prevent overfilling the pump reservoir.
An overfill may cause personal injury due
to excess reservoir pressure created when
cylinders are retracted.

4.1 Lubrication
WARNING: Any repair or servicing, which
requires dismantling the pump must be
performed in a dirt-free environment by a
qualified technician.
CAUTION: Always disconnect air supply before all
maintenance.
If the pump is operated on a continuous duty cycle for
extended periods, the manufacturer recommends an
automatic airline oiler be installed in the air inlet as
close to the pumping unit as possible.
Set the unit to feed approximately 1 drop of oil per
minute into the system. Use SAE No. 10 oil.
4.2 Bleeding Air From The System
During the initial moments of activation or after
prolonged use, a significant amount of air may
accummulate within the hydraulic system. This
entrapped air may cause the cylinder to respond
slowly or behave in an unstable manner.
To remove the air, run the system through several
cycles (extending and retracting the ram) free of any
load. The rams must be at a lower level than the pump
to allow air to be released through the pump reservoir.
4.3 Inspecting The Hydraulic Fluid Level
CAUTION: Always disconnect air supply before all
maintenance.
1. Check the oil level in the reservoir after every
10 hours of use.
2. The oil level should come to within 1/2" of the
filler plug with all hoses attached.
3. Drain and replenish the reservoir with an
approved, high-grade hydraulic oil such as
OTC 16355 after every 300 hours of use.
Hoses: Hydraulic hoses on this unit carry a rating of
10,000 PSI.
Replacement hoses must carry the same rating.
4.4 Draining and Flushing the Reservoir
IMPORTANT: Wipe the pump exterior completely
clean before attempting this procedure!
1. Loosen and remove the six screws that fasten
the pump assembly to the reservoir. Remove the
pump assembly from the reservoir. Do not
damage the gasket, filter, or safety valve.
2. Clean the inside of the reservoir and refill with a
suitable, non-flammable flushing oil. Rinse the
filter clean.
3. Place the pump assembly back onto the reservoir
and secure with two of the six screws. For best
results, assemble the screws in opposite corners
of the housing.
4. Run the unit for several minutes. Use the same
method described in Section 3-7 (Priming the
pump unit)
5. Drain and clean the reservoir once more.
6. Refill the reservoir with an approved, clean
hydraulic oil and replace the pump assembly
(with gasket) on the reservoir. Assemble the six
machine screws and torque 25 to 30 in. lbs.
IMPORTANT: Drain and clean the other hydraulic
system components (hoses, cylinders, etc.) before
reconnecting them to the pump. This will prevent
contaminated oil from re-entering the pump.
4.5 Refilling The Reservoir
CAUTION: Always disconnect air supply before all
maintenance.
1. If additional oil must be added to the reservoir,
use only an approved high-grade hydraulic oil
such as OTC 16355 (215 SSU @ 100° F).
2. Clean the entire area around the filler plug before
adding oil to the reservoir.
3. Remove the filler plug and insert a clean funnel
with filter.
4. The ram must be fully retracted and the air
supply disconnected when adding the oil to the
reservoir.

4.6 Venting the Reservoir
To improve oil delivery and increase useable oil
capacity, vent the reservoir by removing the vent
screw from the filler plug before using the pump.
See Figure 4-1.
4.7 Priming the Pump Unit
If the pump unit must be primed, perform the
following procedure:
1. Depress the release end of the pedal while
holding down the air intake valve with a flathead
screwdriver. The air intake valve is located
directly under the pedal in the area marked
PUMP. This "button" is depressed
simultaneously with the RELEASE area of the
pedal during priming.
2. Allow the pump to cycle approximately 15
seconds.
3. Remove the screwdriver and depress the pump
end of the pedal once more.
4. If the ram extends or pressure builds, the pump
has been sucessfully primed.
5. If the pump does not respond, repeat the
procedure, repeatedly jogging the air intake
valve while holding the pedal in the RELEASE
position.
4.8 Periodic Cleaning
CAUTION: Always disconnect air supply before all
maintenance.
A routine should be established to keep the pump
as free from dirt as possible.
1. All unused couplers should be sealed with
thread protectors.
2. All hose connections must be free of grit and
grime.
3. Any equipment hooked up to the pump should
also be kept clean.
4. Use only approved, clean hydraulic oil, such as
OTC 16355 in this unit and change as
recommended (every 300 hours).
An example of a maintenance chart is shown
below. Copy and use this chart to track the
maintenance of your 19286-1000 or use this as
a template to create you own schedule or use
your company’s standard chart, if applicable.

4.9 Spare Parts
Customers are responsible for maintaining the tool. Spare parts are available from Molex. Moving and
functioning parts can be damaged or wear out over time and will require replacement. Molex recommends that
the customer keep some or all of them in stock to reduce production down time.
4.10 Perishable Parts (Tool Kits)
Customers are responsible for maintaining the 19286-1000. Perishable parts are those parts that come in
contact with the product and will wear out over time. Molex recommends that all customers keep at least one
set of the perishable tooling in stock at all times. This will reduce the amount of production down time.
4.11 Storage
When storing the 19286-1000 assembly, disconnect the air supply and store in a dry location. If the pump is
disconnected from the hydraulic head, reinstall the dust cap on the cylinder inlet. When transporting, reinstall
the red-vented cap on the pump reservoir.
