SP30 14:1 Piston PumpInstallation and Maintenance Instructions

WARNING: Allow only qualified personnel to perform thefollowing tasks. Observe and follow the safety instructions inthis document and all other related documentation.

The hydraulics system consists of the air-driven piston pump assemblyand a manifold assembly. The pump assembly includes an air motor, anactuator, and a dual-acting hydraulic pump.

The manifold assembly is indirectly heated by the tank heaters. Themanifold assembly consists of an aluminum manifold, a filter assembly, adrain valve and hose ports with 45_ connecting elbows.

1. Thread an M4 screw into the top of the spool.

2. Shift the air valve manually for several pump cycles. If the valve willnot move, refer to Actuator Malfunctioning, page 3.

3. If the pump operates when the valve is shifted manually but will notrun on its own, the problem is in the actuator. Refer to ActuatorMalfunctioning, page 3.

4. If the pump will not stroke when the actuator is shifted manually, thepump is jammed, or the air motor is leaking, refer to page 3.

Fig. 4 Title

1. Increase and decrease pump air pressure while triggering the guns.This frees the pump of any lodged particles holding the siphon ball offits seat.

2. If the pump is still stroking erratically, remove the pump assemblyfrom the applicator. Refer to Pump Replacement, page 9, forinformation on removing the pump assembly.

3. Inspect the bottom of the pump body and remove any particlesholding the siphon ball off its seat.
