Positioning Ram
Horizontally
The ram cylinder can be positioned and secured
anywhere along the top frame of the press to align
with off-center workpieces.
To position ram cylinder:
1. Position press bed height (see Adjusting
Press Bed Height on Page 19) to allow ram
adequate space above workpiece.
2. Loosen both cylinder locks, then move
ram till it is directly above workpiece (see
Figure 17).
3. Tighten cylinder locks and lower ram until
it just touches workpiece to ensure cylinder
remains stationary and workpiece does not
shift during operation.
Adjusting Pressure
The amount of force applied to the workpiece can
be adjusted using the pressure adjustment valve
(see
Figure 20).
Force applied to the workpiece is measured in
PSI (Pounds Per Square Inch) on the pressure
gauge. To adjust pressure, turn machine
ON and
pull ram control lever to the DOWN position.
When the pressure for the current setting is
reached, the sound of the motor will change from
a low-pitched whine to a high-pitched whine. The
reading on the pressure gauge will remain sta-
tionary, signaling the regulator is bypassing the
adjustment valve to maintain the current pressure.
Slowly turn the adjustment valve clockwise to
increase pressure or counterclockwise to decrease
pressure.
Stop rotating the adjustment valve once the
desired pressure has been reached on the pres-
sure gauge.

Machine damage may occur if you exert
maximum ram force when it is extended
more than
3
⁄
4
of its total length. Adjust table
height to reduce ram stroke length.
