the piston top, which regulates g the discharge
volume.
To adjust the pump output:
1. Follow Pressure Relief Procedure , page 4.
2. Loosen screw (8k) (F
IG
. 2).
3. Turn hex nut (a) (F
IG

• Clockwise to increase output
• Counterclockwise to decrease output
NOTE: Do NOT exceed 0.484 inch (12.24 mm) to pre-
vent insufficient thread engagement of the cylinder and
piston assembly.
4. When the desired output volume is attained,
re-tighten the screw (8k), and torque the screw (8k)
to 20 in/lbs.
5. Re tighten the outlet fitting or the alternate outlet
plug.
This equipment stays pressurized until pressure is
