3. Attach the free ends of the links to the bottom, outer

surfaces of the handle. Insert a long clevis pin through the

holes on both links and the lowest hole on the handle.

Secure with a small cotter pin. (Figure 2)

4. Insert a screwdriver in the piston shaft of the pump and

pull the piston out. Install the shaft on the handle at either

piston hole by placing a short clevis pin through the handle

and the piston shaft end and securing with the hitch clip pin.

NOTE: Select the upper piston hole on the handle for the 1/2-

gallon setting (Figure 3) or the lower piston hole for the

1/4-gallon setting. Flow settings can be changed at any

time by repositioning the piston shaft on the handle.

CORRECTIVE ACTION

Tighten two screws on the retainer and torque to approximately 20 lb. in. (or hand

tighten then another half turn until leak stops)

Remove the two screws on the retainer and remove the retainer and bearing. Remove

all three seals and replace.

Replace vent plug assembly. Remove the black cap. Remove old vent plug assembly

O-ring damaged

by turning counterclockwise. Install new vent plug assembly. Replace cap.

Remove the pump from the tank. Remove the suction pipe, spacer, and inlet

screen from the bottom of the pump. Clean the inlet screen and assemble. Place

the pump on the tank using installation instructions.

Remove the pump from the tank. Inspect the spacer and suction pipe to ensure

they are not worn or damaged. Replace as necessary and install the suction pipe

and pump again using installation instructions.

Remove the piston cover and inspect the piston ring and liner. Scoring and

worn

severe scuffing on the liner indicates wear. If necessary, install an Overhaul Kit.

Remove the piston cover and inspect the piston. Install an Overhaul Kit, if necessary.

Disassemble and clean the piston and liner. Check for debris lodged in the

liner

piston ring or behind the liner. Small dimples in the liner indicate dirt, debris or

welding slag contaminants in the tank. Replace the piston ring and liner. If

appropriate, flush the tank of all contaminants.

NOTE: Lock the handle to the pump by pushing the handle

against the pump and inserting a padlock through either

of the top holes in the handle and through the pump's lock

hole. (Figure 4)

OPERATION & MAINTENANCE

To Dispense Fluid

1. Remove the nozzle from its holder and insert into the

receiving tank of the equipment or vehicle.

2. Choose a handle setting for the desired flow rate:

– 1/4-gal. setting for low-volume, low-resistance pumping

– 1/2-gal. setting for high-volume, high-resistance pumping

3. To operate pump, manually move the handle in a push/

pull motion.

4. After dispensing the desired amount of fluid, drain the

hose and nozzle. Place the nozzle in its holder and return

the handle to its upright storage position.

During daily use, the GPI HP-100 Hand Pump is essentially

maintenance free. However, the pump should be inspected

periodically for signs of leakage. If leaks are present, make

appropriate repairs. Refer to the Troubleshooting section.
