HYdRAuliC HOses And Fluid TRAnsMissiOn lines
• Avoid straight line tubing connections in short runs. Straight line runs do not provide for expansion and contraction
due to pressure and/or temperature changes. See diagrams in “Set-up Instructions” section of this form.
• Eliminate stress in the tube lines. Long tubing runs should be supported by brackets or clips. Tubes through
bulkheads must have bulkhead fittings. This makes easy removal possible and helps support the tubing.
•
Before operating the pump, all hose connections must be tightened with the proper tools. Do not overtighten.
Connections should only be tightened securely and leak-free. Overtightening can cause premature thread
failure or 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
release all pressure. Never attempt to grasp a leaking pressurized hose with your hands. The force of
escaping hydraulic fluid could cause serious injury.
•
Do not subject the hose to potential hazard such as fire, sharp surfaces, extreme heat or cold, or heavy
impact. Do not allow the hose to kink, twist, curl, crush, cut, or bend so tightly that the fluid 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. Never repair with tape.
•
Do not use the hose to move attached equipment. Stress can damage the hose and possibly cause personal injury.
•
Hose material and coupler seals must be compatible with the hydraulic fluid used. Hoses also must not come in
contact with corrosive materials such as creosote-impregnated objects and some paints. Hose deterioration
due to corrosive materials can result in personal injury. Consult the manufacturer before painting a hose. Never
paint a coupler.
PuMP
•
•
•
•
Do not exceed the hydraulic pressure rating noted on the pump nameplate or tamper with the internal high
pressure relief valve. Creating pressure beyond rated capacities can result in personal injury.
Before replenishing the fluid level, retract the system to prevent overfilling the pump reservoir. An overfill can cause
personal injury due to excess reservoir pressure created when the cylinders are retracted.
Always shut off the motor and relieve pressure before breaking any connections in the system.
The motor or engine is the major part of the weight of the pump. Always take this into consideration when lifting or
moving the pump.
CYlindeR
•
Do not exceed the rated capacities of the cylinders. Excess pressure can result in personal injury.
•
Do not set poorly balanced or off-center loads on a cylinder. The load can tip and cause
personal injury.
•
Read and understand the cylinder operating instructions and warning decals before using the cylinder.
Operator’s Mistake: A double-acting cylinder or ram must have both hoses and all couplers
securely connected to both ports. If one of the two ports is restricted or becomes disconnected, pressure
will build and the cylinder, hose or coupler can burst, possibly causing serious injury or death.
HYdRAuliC Fluids
• Properly dispose of all fluids, components, and assemblies at the end of their useful life. Refer to MSDS sheet.
• Hydraulic fluid should be compatible with all hydraulic components.
•
•
Refer to hydraulic fluid MSDS Sheet for temperature range.
When using a low temperature hydraulic fluid and moving to a non low temperature application, change the fluid to
the appropriate temperature range. Consult the MSDS sheet for useable temperature range.

PuMP OPeRATiOn
When operating the pump for the first time:
1. Valve and hose connections must be tight, and the reservoir must be filled to the proper fluid level. Start the motor.
2. Jog the pump several times to build pressure.
3. Run cylinder out to its full travel several times to eliminate air from the system. For more complete instructions,
refer to the section titled “Bleeding The System” under Set-up Instructions.
4. With the cylinder(s) retracted completely, check the fluid level in the reservoir and add fluid if necessary. Refer to
“Filling The Pump Reservoir” under Set-up Instructions.
5. The pump is now ready to be put into regular operation.
dAngeR: When lifting or lowering a load, the load must be under operator control at all times and
others must be clear of the load. use blocking and cribbing to guard against a falling load.
do not drop the load. The use of a load lowering or metering valve is recommended in
addition to the pump directional control valve.

Priming The Pump
When operating the pump for the first time:
1. Valve and hose connections must be tight, and the reservoir must be filled to the proper oil level. Start the motor.
2. Jog the pump several times to build pressure. If the pump doesn't build pressure, it may not be primed. Short “ON”
time of a 1/4 to 1/2 second repeatedly should prime the pump. An alternate method would be to throttle down the
incoming air supply and run the motor at very low RPM.
3. Run wrench several times to eliminate air from the system. For more complete instructions, refer to the section
titled "Bleeding Air From The System."
4. The pump is ready to be put into regular operation.
iMPORTAnT: After eliminating trapped air from a system with long hoses, retract the wrenchs and refill the
pump reservoir to indicated fill level.
Adjusting The Pressure Regulating Valve
nOTe: For easy adjustment of the pressure regulating valve, always adjust the pressure by increasing to the
desired pressure setting.
1. The pump must be completely connected.
2. Turn knob counter-clockwise to loosen and decrease the setting to a lower than desired pressure.
3. Slowly turn the adjusting knob (B) in a clockwise direction. This gradually increases the pressure setting until the
desired pressure is reached.
iMPORTAnT:
• The pressure range is from 1,000 to 10,000 Psi (69 Bar to 690 Bar) depending on the pump model.

To help prevent personal injury,
• disconnect the pump from the air supply before performing maintenance or repair procedures.
• Repairs and maintenance are to be performed in a dust-free area by a qualified technician.
Bleeding Air From The system
Air can accumulate in the hydraulic system if the reservoir oil level is too low. This air causes the wrench to respond
in an unstable or slow manner. To remove the air:
1. The hydraulic wrench(s) must be positioned on their side(s) with the couplers located upward.
2. Remove any load from the wrench(s), and cycle the hydraulic system through several cycles (fully extend and
retract the wrench(s).
note: The wrench must be at a lower level than the pump to allow air to be released through the pump
Reservoir
Hydraulic Fluid level
1. Check the oil level in the reservoir after each 10 hours of use. Proper oil level is indicated by the “fill line” when
all wrenches are retracted. This is typically 44.5 - 50.8mm (1.75-2.00") from top of fill hole, depending on
tank geometry.
2. Drain, flush, and refill the reservoir with an approved, high-grade hydraulic oil after approximately every 300 hours
of use. The frequency of oil changes will depend upon the general working conditions, severity of use, and overall
cleanliness and care given the pump.
3. The Air Supply Lubricator in the Filter-Regulator-Lubricator requires servicing to replenish the oil level. Check fluid
level every 200 hours or less based on usage.
4. Lubricator oil is GAST#AD220 or an SAE10w High Detergent oil. The consumption rate is 1 drop of oil for every 50
CFM (1.41 L/MIN) air: Typically, 2 drops/min. Do not overfeed or the exhaust air will become contaminated.
Maintenance Cleaning
1. Keep the pump's outer surface as free from dirt as possible.
2. Seal all unused couplers with thread protectors.
3. Keep all hose connections free of dirt and grime.
4. The breather-hole in the filler cap must be clean and unobstructed at all times.
5. Equipment connected to the pump must be kept clean.
6. Use only an approved, high-grade hydraulic oil in this pump. Change as recommended (every 300 hours).
7. The Air supply lubricator in the Filter-Regulator-Lubricator requires inspection every 200 hours.
