ing the safe operation of this tool. The user must read and understand these details
before any use of the tool. This manual must be retained for future reference.
• Read, study, understand and follow all instructions before operating this press.
• Always wear safety goggles, (users and bystanders).
• Parts being pressed may splinter, shatter, or be ejected from the press at a dangerous
rate of speed. Because there are a variety of press applications, it is the responsibility
of the press owner to provide adequate guards, eye protection and protective clothing
to the press operator.
• Visual inspection of the press should be made before use, checking for signs of cracked
welds, bent bed pins, loose or missing bolts, leaks, or any other structural damage.
Corrections must be made before using the press.
• Do not go near leaks. High pressure hydraulic fluid can puncture skin and cause serious
injury, gangrene, or death. If injured, seek emergency medical help as immediate
surgery is required to remove the fluid.
• Prior to use make sure the press is securely anchored to a concrete floor.
• Keep hands, arms, feet, and legs out of work area. Accidental slippage can result in
personal injury.
• Always use an accurate force gauge to measure pressing force.
• Do not exceed the rated capacity or tamper with the pressure/force settings. When
attachments and adapters are used the rated capacity of the system shall be no greater
than the rated capacity of the lowest rated component or combination of components
that make up the system.
• Avoid off-center loads. Offset loads can damage ram and may cause load to eject at a
dangerous rate of speed. Do not use any spacer or extender between the press ram
plunger and the item being pressed. If there is not enough ram stroke, adjust the height
of the movable bolster.
• Remove all loads from movable bolster before attempting to adjust bolster height.
Beware of possible falling bolster.
• Press only on loads supported by movable bolster and press plates included. Do not
support loads on floor or press frame legs.
• When using any accessories such as press plates or arbor plates, be certain they are
centered on the movable bolster and in full contact with both sides of the bolster.
• Before applying load, be certain all movable bolster supporting pins are fully engaged.
Verify lift cables (if equipped) are slack before pressing on the bolster.
• Always use a bearing shield when pressing bearings.
• Use caution when positioning work to be pressed to ensure the item to be pressed
cannot be ejected at a dangerous rate of speed.
• Release hydraulic pressure before loosening any fittings.
• Maintain proper hydraulic fluid levels.
• Do not make any alterations or modifications to the press.
• This product may contain one or more chemicals known to the State of California to
cause cancer and birth defects or other reproductive harm. Wash hands thoroughly
after handling.

RAM ASSEMBLY INSTRUCTIONS
1
Forklift located behind press
WARNING
Begin behind the press. Using a forklift, place
the pump on the back side of the forks, closest
to the mast as shown in the diagrams.
- The ram should be upside down with the gauge
facing toward the press.
- All hoses should be between the forks.
Note: Handle ram carefully to avoid damage
to gauge or gauge face. Do not disconnect
hoses prior to assembly.
The press must be on a hard, flat surface, bolted to the floor if
necessary in the position in which it will remain for the life of
the equipment.
Align the front end of the
forks with the four holes in the top
of the press, matching them up with
the four holes in the top of the ram.
2
Slowly move the forks up toward the top
of the press, making sure the holes in the
top of the ram are aligned with the holes
in the press. The pump assembly will still
be resting on the forks.
Top of press, looking down and inside
TO BOLT RAM TO PRESS, stand on a sturdy ladder and look
down into press from the top. Use the provided
1/2-13 x 3/4" hex head bolts and washers, offsetting the
first two bolts and washers for more precise alignment.
Finish with the other two bolts and washers until the ram is
completely secured to the press frame. These four bolts will
thread directly into pre-tapped holes in the ram.
Slowly move the forks back down toward
the bottom of the press, leaving the ram
securely attached at the top. Stop about
mid-way down to easily remove and
place the pump assembly.

WARNING
Using at least two people, lift the pump assembly
off of the forklift and orient the pump so that the
plastic tank is on the bottom. Align with holes on
right side of press frame.
Using the 1/2"-13 x 1-1/8" hex head bolts, nuts
and washers provided, attach the pump assembly
to the press frame. (Line up a bolt and a washer
in the inside of the frame first. Finish with the nut
attached under the pump assembly. Repeat with
other hole.)
CAUTION
Never allow hoses to kink, twist, curl or bend so tightly that
the oil flow within the hose is blocked or reduced. This could
damage the hose and possibly result in serious injury to
persons working in the immediate vicinity.
All hoses should run BEHIND
press frame and should be free
of kinks, twists or bends.

RAM OPERATING INSTRUCTIONS
1. Check to ensure all connections are secure and all bolts and nuts are tightened.
2. Place press plates DIRECTLY under ram, on press bed. ALWAYS center load and press blocks.
2. Plug in the pump assembly.
3. Flip switch on top of pump assembly.
4. Use remote to operate ram.
5. Pump should now operate normally. Repeat steps 1-4 if necessary.
Note: Sometimes the ram moves in the opposite direction of the arrows on the remote. Do not be alarmed if this happens, as it is commonplace in the initial wiring.
Make a note if this does occur. You may reverse your hydraulic lines on either pump or ram. Move the ram up and down accordingly.
Note: The remote control is magnetic and will stick to the steel press frame when not in use.
WARNING
Do not allow the ram to extend more than 6.125" (6-1/8").
