Pressure Control Replacement
NOTE: See Fig. 7 except where noted.
1.
Disconnect the red, black and white wires from the
rectifier (307) which are sheathed with the conduc-
tor (309). Unscrew the connector (313 or 105)
from the control box, pulling the conductor and
wires out with it.
2.
For the upright sprayer, remove the nipple (312)
from the elbow (314).
3.
Use a wrench to hold the hex of the adapters (A)
while removing the elbows (314 or 322).
4.
Reassemble in the reverse order.
For the Upright carts, guide the new pressure
control wires through the wire clamps (32). Fasten
the wire clamps to the cart with the same screws,
lockwashers, and nuts (62, 9, 61) which hold the
bracket (67) to the cart. See Fig. 6, on page 15.
For the Lo–boy carts, guide the pressure control
wires through the single wire clamp (32), and in-
stall the screws (62) and washers (9) to hold the
bracket (67) to the cart. See Fig. 6, on page 15.
5.
Perform the Pressure Control Adjustment on
page 17 before regular operation of the sprayer.
