PRODUCT DESCRIPTION
Atd Tools Bench Press & Shop Press are designed for automotive, truck, implement, eet, and industrial repair shops
where pressing, bending, straightening and forming, is required. Typical applications include installation and removal
of alternator and power steering pump bearings, axle bearings, transmission bearings, seals, u-joints and others. It
is not intended for use as an assembly table or as xture stand used to secure a large, nal assembly component.
Unlike presses equipped with a separately mounted pump, the power unit on this press can not be equipped with a
pressure gauge, therefore monitoring the load must be done by other means, such as a load cell w/ digital indicator.
Whatever means is chosen, the load measuring means shall be calibrated annually.

PREPARATION
Before Use
1.
Verify that the product and application are compatible, if in doubt call Atd Tools technical service (636) 327-
9050.
2. Before using this product, read the operator's manual completely and familiarize yourself thoroughly with the
product, its components and recognize the hazards associated with its use.
3. To familiarize yourself with basic operation of bottle jack (use the notched or stamped end of provided handle to
engage) or hand pump and turn the release valve:
a. Clockwise until rm resistance is felt to further turning. This is the ‘CLOSED’ release valve position used to
extend the ram.
b. Counter-clockwise, but no more than 1 full turn from the closed position. This is the ‘OPEN’ release valve
position used to retract the ram.
4. With ram fully retracted, remove the oil ller plug. Insert the handle into the handle sleeve, then pump 6 to 8
strokes. This will help release any pressurized air, which may be trapped within the reservoir. Ensure the oil level
is just below the oil ller hole. Reinstall the oil ller plug.
5. For model Atd-7455: withith release valve opened, remove the oil ller screw. Ensure the oil level is within 1/4"
(6mm) of the opening. Reinstall the oil ller screw.
6. Check that the pump operates smoothly and that the extension screw will thread up/down easily before putting
into service. Replace worn or damaged parts and assemblies with Atd Tools authorized replacement parts only.
Bleeding / Venting Trapped Air
With the release valve in the OPEN position (3b above) and with ram fully lowered, remove the oil ller plug. Insert
handle into the handle sleeve; then pump 6 to 8 full strokes. This will help release any pressurized air which may be
trapped within the reservoir. Oil level should be even with the bottom of the oil ller hole. Reinstall the oil ller plug.

OPERATION
!
Ensurethatworkpieceiscenter-loadedandsecure.Reduceriskofyingdebrisbycare
all operating instructions. Know your press and hazards associated with its use.
Crush Hazard! Keep hands and feet from bed area at all times.
1.
Insert the support pins to desired height, then lower the bed. Ensure bed frame is fully rested on the support pins.
2. Place arbor plates on the bed frame as needed.
3. Place workpiece on bed frame, using every precaution necessary to ensure your safety and prevent property
damage. Position workpiece in a manner which will not allow it to inadvertently fall from bed.
4. Close release valve by turning it clockwise rmly, insert jack handle into handle sleeve, and pump the handle to
extend the ram until ram nears workpiece.
5. Align ram and workpiece to ensure center-loading.
6. Apply load to workpiece by pumping handle. Do not overload workpiece
7. Monitor the pressure gauge and calcualte the applied load using the following formula as basic guideline:
Force = Pressure X Area
Projectile Hazard! Wear ANSI approved eye protection. Never stand directly in front of loaded press.
fully following
Effective Area of model Atd-7455 = 5.14 in²
Problem: Determine the applied load in lbs. force on a workpeice being pressed by a Atd-7455 whose pressure
gauge is reading 2200 psi.
Solution: 2200 X 5.14= 11,308 lbs
8.
Stabilize workpiece in a manner which will not allow it to inadvertently fall from the bed once the load is removed,
then turn release valve counter-clockwise to retract the ram and remove workpiece. Do not turn the release valve
counter-clockwise more a 1 full turn.
To reduce the risk of personal injury and/or property damage, ensure that the rated working pressure of each
!
pressurized attachment be equal to or greater than the rated working pressure developed by the pump.
Use only handle provided by manufacturer. The handle provided with this product will safely engage the
!
release valve of bottle jack and operate the handle sleeve. If handle is worn, operates abnormally, or will not
positively engage the release valve, STOP, discontinue use of the jack until a factory replacement handle can be
acquired.
6
Unlike presses equipped with a separately mounted pump, the power unit on this press can not
!
be equipped with a pressure gauge, therefore monitoring the load must be done by other means,
such as a load cell w/ digital indicator. Whatever means is chosen, the load measuring means shall be calibrated
annually.
The hydraulic power unit provided with this device is intended to be used as an integral part of this press and
!
not as a stand-alone jacking device separate of the press. Never use the hydraulic power unit provided with
this press for any purpose other than that for which it is intended.
MAINTENANCE
Before each use, inspect press for damage. Do not use if bent, broken, cracked, leaking or otherwise damaged
components are noted. Periodically, lightly oil all moving parts, including the pump piston and ram.
Adding/Changing oil to bottle jack
For Bottle Jack models Atd-7452, Atd-7453 & Atd-7454:
Important: Use only good grade hydraulic jack oil. Avoid mixing different types of uid and NEVER use brake uid,
turbine oil, transmission uid, motor oil or glycerin. Improper uid can cause premature failure of the jack and the
potential for sudden and immediate loss of load. Mobil DTE 13M or equivalent recommended.
For best results, change uid once a year.
1. Remove jack from press frame.
2.
With ram fully lowered and pump piston fully depressed, set jack in its upright, level position. Remove oil ller plug.
3. Drain used uid into a suitable container
Note: Dispose of hydraulic oil in accordance with local regulations.
4. Fill until oil is level with or just below ller plug hole.
For hand Pump model Atd-7455:
1. Depressurize and disconnect hydraulic hose from application.
2. Remove oil ller screw located on top of the reservoir.
3. Pour used uid into a sealable container.
Note: Dispose of hydraulic uid in accordance with local regulations.
4.
With pump in its upright, horizontal position, use a small funnel to ll reservoir to within 1/4” (6 mm) of the opening.
5. Wipe up any spilled uid and reinstall the vented oil ller screw.
Rust prevention
Check ram and pump piston for signs of rust on a regular basis. Clean as needed with a lint free, oil saturated cloth.
Never use sandpaper or abrasive material on these surface.
How to remove faulty coupler:
If ram does not retract: Depressurize pump and hose, then remove the ram from application. Disconnect and
replace with new coupler.
Important: Do not attempt to grasp ram with pliers or wrench without rst wrapping the jaws of such tool with rags
or similar padding.
How to bleed air from system:
1. Place pump at a higher elevation than the hose and ram as
shown in gure 4.
2. Operate pump to fully extend and retract the ram 2 or 3 times.
The objective is to force the air bubbles up hill and back to the
pump reservoir.
3. To bleed the air from pump reservoir, simply open the oil ller
screw. Re-install after bleeding.
