SPECIfIC mAINTENANCE

PUMP:
The pump oil must be changed after the first 5 hours of operation.

Once the initial oil change has been completed, it is recommended the

oil be changed every months or 50 hour intervals. If oil appears

dirty or milky, changes may be required at a greater frequency. Use

John Deere Hy-Guard and fill only to the center of the oil sight glass.

DO NOT

OVERFILL!

NOZZLES:
Water flow through the spray nozzle will erode the orifice, making it larger,

resulting in a pressure loss. Nozzles should be replaced whenever pressure

is less than 85% of the maximum. The frequency of replacement will depend

upon such variables as mineral content in the water and number of hours the

nozzle is used.

QUICK COUPLERS:
There is an o-ring seal inside the female quick coupler. This o-ring will deteriorate

or, if the unit is allowed to pump without the high pressure hose or nozzle

attached, the o-ring may be blown out occasionally. Simply insert a replacement

o-ring to correct the leak. (Additional o-rings can be purchased from your John

Deere dealer.)
