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.
How to Check/Clean the Heat Exchange Coil
The heat exchange coil should be inspected for deposit build-up after 40 hours of use, or once a month,
whichever comes first. In hard water areas a water softening system should be employed.
Scaling or liming of the coils is caused by mineral deposits from the water and occurs much faster in hard-
water areas and with heavier machine usage. Lime build-up can also be caused by inferior cleaning com-
pounds.
DANGER:
Failure to properly maintain the heat exchange coil can result in a steam explosion!
Scale or lime build-up will act as an insulation and decrease the efficiency of the
heat exchanger coil and will also cause "hot spots". This can result in a weakening
of the tubing which can lead to a steam explosion.
Explicit instructions for inspecting and cleaning the heat exchange coil can be found in your Delco Operator
Safety Manual that came with your pressure washer. The part number for that manual is 78351A. If you
didn't receive one when you bought your pressure washer contact your local Delco distributor and request
one or call Delco's customer service department at 1-800-BUY-DELCO.
