16 Nilfisk-Advance Select Spray 2700G Operator’s Manual
STORAGE & MAINTENANCE
SPECIFIC MAINTENANCE:
ENGINE: The engine instructions that accompany your unit detail specific
procedures for maintenance of the engine. Following the engine
manufacturer’s recommendations will extend engine work life.
PUMP: The pump oil must be changed after the first 25 hours of operation.
Once the initial oil change has been completed, it is
recommended the oil be changed every 3 months or 250 hour
intervals. If oil appears dirty or milky, changes may be required
at a greater frequency. Use SAE 30W non-detergent pump oil
and fill only to the center of the oil sight glass (12). DO NOT
OVERFILL!
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
dealer.)
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.
