SETUP INSTRUCTIONS
WARNING
Failure to follow these Setup Instructions may result in serious injury or death, and/or property damage.
1. Refer to the exploded view drawing on page 6 and 7 to identify shop press components.
2 Loosely assemble the upper beams (#10) to the one post (#20) at one end with the bolts (#9), washers (#11), spring washers (#12) and nuts (#13) as shown
in the exploded view drawing. Slide the ram plate (#7) on the beams (#10). Loosely assemble the other ends of the upper beams (#10) to the other post
(#20). All hardware will be tightened at a later time.
3 Place the lower cross member (#26) between the two posts (#20) so the holes at either end of the cross member line up with the holes in the bottom of the
posts. Align the holes in the feet (#21) with the same holes in the bottom of the posts (#20) as shown in the exploded view drawing. Secure the feet, posts
and lower cross member together using the bolts (#25), washers (#22), spring washers (#23) and nuts (#24).
4 The four supports (#34) are used to keep the posts (#20) perpendicular to the feet (#21) when installed. Install one end of the supports (#34) to the holes in
the posts (#20) with the bolts (#33), washers (#14), spring washers (#15) and nuts (#16). Do not tighten until later. Install the other ends of the supports
(#34) to the feet (#21) with the same hardware (#33, 14, 15 and 16).
5 Tighten all hardware mentioned in steps 1 through 4 making sure the feet (#21) are flat on the floor and posts (#20) are perpendicular to the floor.
6 Secure the pump assembly plate (#31) to the post (#20) with the bolts (#36), washers (#22), and nuts (#24) as shown in the exploded view drawing. The
oval hole in the pump assembly plate (#31) should face towards the operating side of the press.
7 The pump (#32) must be secured to the pump assembly plate (#31) with the washers (#30) and bolts (#29).
8 Screw the upper round nut (#6) all the way on the threads of the ram assembly (#3). Insert the end of the ram (#3) through the hole in the ram plate (#7)
until the upper round nut (#6) rests on top of the ram plate (#7).
9 The threads of the ram assembly (#3) should be exposed below the ram plate (#7). Screw on the lower round nut (#8) on the ram threads just until the nut
engages all the threads. Raise the ram up until the top of the lower round nut (#8) is up against the bottom of the ram plate (#7) and then screw down the
upper round nut (#6) until plate (#7) is sandwiched between the upper and lower round nuts. Tighten set screws in the upper and lower round nuts.
10 Insert the nylon ring (#2) in the fitting on top of the ram assembly (#3) and install the gauge (#1) in the fitting. Tighten the gauge in the fitting so the face
of the gauge is pointing towards the operating side of the press.
11 Install the coupler at the end of the oil hose (#39) in the coupler of the ram assembly (#3) and tighten by hand only.
12 Install the adaptor (#5) in the bottom of the ram assembly (#3) and tighten the screw (#4).
13 Tilt the work bed (#18) so that each end will straddle the posts (#20). Raise the work bed to the desired height and closest to the holes in the posts (#20).
Insert the pins (#19) through the holes in the posts (#20) and secure the pins in the holes by inserting the clips (#35) in the ring grooves of the pins (#19).
The work bed (#18) can now rest on the pins (#19).
14 If the back end of the pump (#32) is equipped with a fill screw (#38) that also serves as a breather for the pump's reservoir, turn the screw counterclock-
wise until it stops.
15 Sometimes during shipping and handling, air may become trapped in the hydraulic system and cause the pump to malfunction or not achieve a full
pump stroke.
PURGING AIR FROM THE HYDRAULIC SYSTEM:
a. On the side of the pump (#32) is a knob that must be turned clockwise all the way until it stops in order to extend the ram (#3) during the pumping
operation. Turn the knob counterclockwise two full rotations from its stop position. Install the pump handle (#37) in the pump's handle receiver and
operate the pump 10 full incremental pump strokes.
b. Turn the knob clockwise until it stops. Activate the pump to see if the ram extends correctly.
c. If the condition seems better but air not fully purged, repeat steps a through b until all of the air is purged out of the system.
