PRODUCT DESCRIPTION
Mac Tools 10,000 PSI Heavy Duty Hydraulic Treadle Pump is designed to meet or exceed ANSI B30.1 Standards for
Performance and Safety. Its unique hydraulic circuit allows quick displacement of hydraulic fluid under no load conditions
and easy pumping in loaded conditions. These foot actuated pumps supply compressed hydraulic fluid to compatible
applicationsi.e.rams, presses, spreaders,compactors and crimpingmachines, anywhere that10,000 PSI offluid pressure
is needed. Specialskill,knowledge and trainingmay be requiredfor aspecifictask andthe productmaynot be suitablefor
all the jobs described above. Unsuitable applications would include applications that call for a device to move, level or
support persons, animals, hazardous materials, mobile homes/ dwellings in general, mirrors and/or plate glass, and/or to
connect/secure hatches, components, etc. between bulkheads. The user must ultimately make the decision regarding
suitability of the product for any given task and assume the responsibility of safety for himself and others in the work area.
Thiscategoryof Mac Tools Equipmentallows quickdisplacement ofhydraulic fluid,up to 10,000PSI, tocomparable rams,
presses,spreaders,compactorsandcrimpingmachines,anywherethat10,000 PSI of fluid pressure isneeded.Foot/Hand
Actuatedtreadle design deliversacontrollable flowto andfromthe intended application.
Note: Always check connections before using !

(blackcolor) beforeuse.
3. Pour a teaspoon of good quality, air tool lubricant into
the air supply inlet. (See Illustration) Connect to air
supply and to application, then operate for 3 seconds
to evenly distribute lubricant.
4.Use adequate eyeprotectionwhen operatingor near
thisequipment.
Note:Always secure threaded port connections with
non-hardeningpipethreadcompound.Tightensecurely
toprevent accidental removalof componentswhile in
use.Take care not to introduce compound into port
orifices. Familiarize yourself with the specifications and
illustrations in this owners manual. Know your pump, its
limitations and how it operates before attempting to use.
Refer to Specification chart on page 2 for details of oil
port thread size, usable oil capacity, and more.
OPERATION
1. Remove plastic cap, connect air nipple to air input port
beforeconnecting air hose.
2. connect to suitable air supply, then connect to suitable
application.
3.To operate pump, press on the horizontal portion of the
foot pedal until desired pressure, load or position is
reached.Alwaysmonitorpressure,loadorpositionusing
suitable equipment. Pressure may be monitored by
meansofan optional manifoldand gauge. Loadmay be
monitored by means of a load cell and digital indicator.
Correct application position can only be determined by
theoperatorof the equipment.
4.To retractapplication, simply press the releasevalve by

WARNING
• Read and understand all warnings, instructions and
owners manual information before attempting to use
thisequipment.
• Burst hazard exists if hose or connection pressure
exceedsrated pressure.
• Do not exceed the rated capacity of this device.
•Usegaugeorother load measuring instrumenttoverify
load.
•Alwaysinspecthosesand connectionsfordamageprior
to use.
•Alwayswearprotectiveclothingandeyeprotectionwhen
operatingthis equipment.
•Always ensure that the chosen application is stable to
workon and around.
•Donotworkunderaliftedloadwithoutadequatelyrated
support devices such as jack stands.
• This device is not suitable for use as support device!
• Do not subject the pump and its components to shock
loads.
• Do not connect to application which can return more
oilto the reservoirthanthe pumpreservoir canhold.
• Failure to heed these warnings may result in personal
injury as well as property damage.

MAINTENANCE
1.Inspecthosesandconnectionsdaily.Replacedamaged
components immediately with Mac Tools Authorized
Replacement Parts only.
2. Tighten connections as needed. Use pipe thread seal-
ing compound when servicing connections.
NOTE:DONOT OVER TIGHTEN CONNECTIONS.
3. Use only good quality hydraulic fluid. We recommend
MobileDTE 13M orequivalent.
Important: Use only a good grade hydraulic oil.Avoid
mixing different types of fluid and NEVER use brake
fluid, turbine oil, transmission fluid, motor oil or glycerin.
Improperfluidcancause premature failure ofthe pump
and the potential for sudden and immediated loss of
load.
Adding Oil
1.Disconnecthydraulic hose fromapplication, removeair
sourcefrom pump.
2.With reservoirhorizontal,remove the vent/ oilfiller plug.
3. Use a small funnel to fill reservoir to within 1/4 inch (5
mm) of the opening. Reinstall the vent/ oil filler plug.
Changing oil
1. For best results, change fluid once a year.
2. Repeat # 2 above, then pour used fluid into a sealable
container.
3. Dispose of fluid in accordance with local regulations.
4.Fillwith a goodquality hydraulic jackoil as recommended
above.Reinstall vent/ oilfiller plug.
Lubrication
(Whenno In-Line Oilerisused)
1. When used daily, pour a teaspoon of good quality air
tool oil into the air source inlet of pump. Connect
hydraulic hose to application, connect air source to
pumpand operate pumpafew secondsto evenly
distributefluid.
2. Use a light machine oil to lubricate pivot points, hinges
etc.
Storage
When not in use or during storage:
a. Disconnect pump from air source, depressurize and
disconnect hydraulic hoses from application.
b. Wipe clean, thoroughly.
c.Shelter thepump withprotectivecover.
d. Store in clean, dry environment. Avoid temperature
extremes.
NOTE: Never operate pump while disconnected from
application. If operated in this condition, the hose and
connections become pressurized. This increases the
burst hazard. Damage may occur to pump and its
components.
