1 (Fig 4).
4. Turn dial 3 (Fig 4) counter clockwise all the way out. This relieves
the pressure on the springs and minimizes start-up problems.

closed).

Fluid Sy s tem Overview
When the 500/600 pump A (Fig 3) is running, pressurized fluid flows
from the tank to the M600 brass manual control B (Fig 3). When the

bypass line and agitation nozzle
D (Fig 3). When the main ON/OFF
valve is “ON” and the red handle on the spraygun is depressed, fluid
flows to the spraygun
C (Fig 3). Optional boom: when main ON/OFF
valve is “ON” and boom valve E* (Fig 4) is open, fluid flows to the
