SPRAYER START UP

1. Fill the engine with oil according to the engine manufacturer’s specifica-
tions. (SAE 30).

2. Fill the pump with 30-weight oil, until the oil level is at the full mark on the
pump oil sight gauge or dip stick.

3. Check the grease cups (ref # 50) to ensure they are full of grease.

4. Make sure all hoses are properly secured.

5. Make sure there is liquid in the tank.

6. Position the pressure bypass lever (ref # 108) on the pressure regulator in
the fully clockwise (up) position. This relieves all pressure and bypasses all

the liquid being pumped, back into the tank.

7. Start the engine and set the engine speed at approximately 3200-3400 RPM.
These use air cooled engines and should be run at full throttle during use.

8. Close all the discharge valves allowing only the return line into the tank to
remain open.

9. Check inside the tank to be sure there is liquid being pumped back into the
tank through the return agitator.

10. Unscrew the threaded regulator handle (ref # 101) until it comes out of the
regulator. Then put it back and screw it inward four (4) turns only.

11. Place the lever on the pressure regulator (ref # 108) in the fully counter­clockwise (down) position. A slight pressure should register on the pressure

gauge.

12. Screw the regulator handle (ref # 101) inward until the desired operating
pressure is obtained on the pressure gauge. Then, open all valves to the
hose reel and place the spray gun in the open position, spraying back into the
tank through the lid. The pressure may drop slightly, but this is normal. If
the pressure drops below the desired pressure, adjust the regulator handle
(ref #101) inward one (1) turn. If the pressure increases, continue to adjust

inward until desired pressure is obtained with the spray gun in the “on” posi-

tion. When the desired pressure is obtained, you are ready to go to work. !!!
NEVER EXCEED 600 PSI !!! If the pressure will not go up to the desired oper-

ating pressure, do not continue to adjust the regulator screw handle inward.

13. !! LEAVE THE SPRAY GUN IN THE ON POSITION AND GO TO STEP 15.

14. Adjust the pressure regulator screw handle in the reverse direction until the
pressure starts to drop, and place the pressure regulator bypass lever (ref
#108) in the full (up) clockwise position. Then place the spray gun in the off

position.

15. Re-check the engine RPM to make sure it is at 3200-3400 RPM.

16. If you had to make any adjustments in step 15 or 16, repeat steps 10
thru 15

17. If you still cannot get the desired operating pressure, change the spray
gun tip to the next smaller size, and repeat steps I thru K.

18. If you still cannot get the desired operating pressure, go to the trouble
shooting guide (SECTION V.) or call GNC Industries, Inc. at 800-462-
2005 or 870-248-9901.

SPRAYER SHUT DOWN AND STORAGE

1. Run the pump until all liquid is pumped out of the system. Do not run

the

pump dry for more than 30 seconds. Then shut the engine off and fill the

tank with clean, clear water. Pump the tank empty. If the sprayer is

going

to be stored for several days, the following procedure is recommended:

2. Put 1 gallon of anti-freeze and 1 gallon of water or equivalent in the tank
if temperatures are expected to be below 0°F. Check the freeze chart
of the anti-freeze and add anti-freeze to recommended rating for ex­pected temperatures.

3. Start the engine and allow the pump to operate just long enough to fill
the system with the anti-freeze solution. This is accomplished when only
anti-freeze mixture is coming out of the spray gun. Close the spray gun
and allow the pump to operate for 1 minute.

4. Shut the system off and place in storage. This procedure keeps all the
valves and other moving parts protected during storage.

5. When you are ready to use the system again, start the engine and allow
the pump to operate until all anti-freeze has been pumped out of the
system. Fill the tank with clear water and one bottle of ammonia-based
cleaning liquid. Run the pump until this solution has been pumped out.
Refill the system with clear water and pump the system dry once more.
The spray system is now ready to go to work.

NOTE: The above procedure is highly recommended for sprayers in cold cli­mates as a prevention of freezing and breaking the pump.
STANDARD MAINTENANCE CHECKS

FILLING AND CHANGING LUBRICATION OIL
Take off the oil cap (ref # 4) and fill with 30-weight oil to the full line on the
indicator window or dip-stick. It is recommended to change oil every one
hundred (100) hours of operation.
