Maintenance - Delco Avenger 1000-3 NG Operator's Manual

MAINTENANCE

1. Use a water softener on your water system if it is known to be high in mineral content.
2. Use only high quality Delco chemicals and follow the manufacturer's mixing instructions.
3. The cleaner should be flushed thoroughly after using the chemical solutions.
4. Follow the fuel specifications as outlined in the machine specifications.
5. Clean the strainer screen in the hose connection at float tank periodically.
6. Pump lubricant: Periodically check the oil level. Change the oil after 50 hours of operation, and then after every
500 hours. Use SAE 30 weight non-detergent oil.
7. Use teflon tape or approved sealer on the plumbing connections when reassembling to prevent leakage.
CAUTION: If the machine is to be out of service for a long period of time, we recommend that the system be flushed
out with anti-freeze water solution. Do not run the pump dry for extended periods of time or severe
damage will occur.
8. Deliming coils: Periodic flushing of the coils is recommended to extend coil life and prevent lime build up. See
note on page 11.
How To Check The Oil
It is critical that the oil in your pump be checked regularly. To check the oil follow this procedure:
1. Locate the oil dipstick in the plug on the top of the pump.
2. Turn the oil plug counterclockwise.
3. Wipe the dipstick with a clean cloth.
4. Screw the dipstick in. Pull it back out and check for the oil level mark. The oil level should be at the top mark.
5. If the oil is below the notch, add SAE 30 weight, non-detergent oil.
6. Put the dipstick back into the hole.
7. Turn the plug clockwise until it stops.
NOTE: Change the oil after the first 50 hours of use and then after every 500 hours of use. SAE 30 weight oil must be
used.
Freeze-Up Prevention:
To prevent freeze-up follow these instructions:
1. Drain the float tank.
2. Remove the spray nozzle from the wand.
3. Mix antifreeze concentrate and water in a large container. Read the recommended mixing instructions given with
the antifreeze.
4. Fill the float tank with the antifreeze mixture.
5. Put the end of the chemical line in the float tank. Fully open the metering valve.
6. Turn the control switch to position one.
7. Let the pump run until the antifreeze moves through the pump, coils, and pressure hose.
NOTE: The trigger on the gun must be pulled to allow antifreeze to pass through the coils, and then the trigger must be
released to allow the antifreeze to pass through the bypass line.
8. Turn the control switch to the "O" position and close the metering valve.
9. Unplug the cord and put the machine in a dry building.
