OPERATING PRECAUTIONS

WARNING HAZARDOUS PRESSURE. Do not exceed maxi-

mum operating pressure of 1500 p.s.i. (103 bar) at 150 p.s.i.

(10.3 bar) inlet air pressure.

PUMP RATIO X

INLET PRESSURE TO PUMP MOTOR

Pump ratio is an expression of the relationship between the pump motor area and the

lower pump end area. EXAMPLE: When 150 p.s.i. (10.3 bar) inlet pressure is supplied

to the motor of a 10:1 ratio pump it will develop a maximum of 1500 p.s.i. (103 bar) fluid

pressure (at no flow) - as the fluid control is opened, the flow rate will increase as the

motor cycle rate increases to keep up with the demand.

WARNING Refer to general information sheet for additional

safety precautions and important information.

OPERATING INSTRUCTIONS

1. Fill air line lubricator bowl with SAE 90 gear oil.

2. Oil the lower pump assembly section by squirting SAE 90 Gear Oil

into the two holes marked "Oil Daily".

3. Fill the cleaning solution container with clear water.

4. Connect the air supply line to the air line lubricator.

5. Open the (G) control handle assembly by squeezing the trigger until

water sprays out the spray tip.

6. Adjust air line oiler to approximately 1 drop every 2 minutes by turn-

ing adjusting screw clockwise for less flow.

7. Close control handle.

8. Add the proper amount of cleaning solution to cleaning solution con-

tainer. Insert the (N) bent pipe assembly into the cleaning solution

and open the control handle assembly. Continue holding the control

handle open until spray from the (N) bent pipe assembly has thor-

oughly mixed the cleaning solution.

NOTE:

• Most cleaning solutions will perform more efficiently in warm wa-

ter.

• Powdered detergents will be easier to mix if they are dissolved in

a container of hot water first.

• Consult chemical manufacturer's recommendations for proper

mixing and concentration

9. The air supply line should be disconnected when the wash pump as-

sembly is not in operation.

CAUTION: DO NOT ALLOW THE AIR MOTOR TO RUN AFTER THE

SOLUTION CONTAINER IS EMPTIED.

CLEANING INSTRUCTIONS

Use the cleaning instructions supplied by the cleaning chemical supplier.

General cleaning instructions for detergents and caustics: (In the event

cleaning instructions are not supplied by chemical supplier).

1. Lightly and rapidly cleaning solution to object being cleaned.

2. Let cleaning solution stand on the object for two or three minutes.

3. Starting from the bottom up, clean the object with cleaning solution

holding the spray tip 6 to 8 inches away from object and at approxi-

mately 45_. The 45_ angle will produce a chiseling effect for better

cleaning.

4. Rinse the object thoroughly with clean water from the top down.

General cleaning instructions for aluminum brightening: (If not supplied

by chemical supplier).

1. Apply aluminum brightener to an area of approximately 100 square

feet (approximately 3 semi-trailer panels) from the bottom up.

2. Let the brightening solution soak until light foaming occurs on the

aluminum.

3. Rinse thoroughly with clear clean water from the top down.

CAUTION: Brightening solution will etch glass and will burn alumi-

num if permitted to soak after the light foaming occurs.

NOTE: Pump should not be operated continuously at speeds in excess

MAINTENANCE

The basic pump consists of two major components: 1. Air Motor, 2. Low-

er Pump End. The air motor is connected to the lower pump end by a

spacer tube - this allows access for lubricating the upper packing gland

in the lower pump end, and to prevent air motor contamination because

of normal wear and eventual leakage through material packing gland.

The air motor is removable and is to be serviced separately. Refer to air

motor manual for service and parts.

• Periodically flush entire pump system with a solvent that is compat-

ible with the material being pump.

• Periodically inspect and replace if necessary the (M) screen assem-

bly on the bottom of the (H) suction tube assembly.

• Refer to Disassembly Procedures of air motor and lower pump end

(see Page 3 and 4) for correct breakdown.

• Disassembly should be done on a clean work bench with clean

cloths to keep parts clean.

• If replacement parts are necessary, consult drawing containing

parts for identification.

• Before assembling, lubricate parts where required. When assem-

bling "O" rings or parts adjacent to "O" rings, care must be exercised

to prevent damage to "O" rings and "O" ring groove surfaces.

Daily Maintenance

1. The airline lubricator should be filled with SAE 90 weight gear oil.

2. Maintain the oil level on the packings in the lower pump assembly.

Use SAE 90 weight gear oil.

3. The air line should be disconnected from the air motor if the pump

sits idle for long periods.
