WARNING
To reduce the risk of serious bodily injury, al-
ways follow the Pressure Relief Procedure
Warning on page 14 before checking or re-
pairing any part of the spray system.
NOTE: Refer to Fig 22 except where noted.
NOTE: In Fig 22, the pressure control is shown
pulled away from the cart for visual pur-
poses only. You do not have to remove
the pressure control to replace the motor.
1. Remove the sprayer's shroud and the lift han-
dle (2). Remove the drive assembly (8). See
page 22. The pump, connecting rod and bear-
ing can stay assembled to the drive assembly.
2. Drive out the pin (61). Remove the gear (60).
See Fig 21.
3. Remove the pressure control cover (7). Dis-
connect the motor leads. See Fig 22.
4. Unscrew the connector nuts (13c & 305) on
both ends of the conduit (13f). See Fig 22.
CAUTION
Always pull the motor leads one at a time to
avoid loosening the terminals.
5. Remove the motor mounting screws (38). See
Fig 20. Lift the motor off the frame and care-
fully guide the wires through the pressure con-
trol connector (305). Remove the conduit (13f)
from the wires. See Fig 22.
6. Unscrew the connector (13c) from the motor.
Do not twist the wires. See Fig 22.
7. Install the new motor in the reverse order.
NOTE: A circuit board (13b) is included with a
new motor. See page 18 for installation.
MOTOR & CAPACITOR
8. Clean the gear (60) and inspect it for wear or
damage. Replace if necessary. Secure the
gear with the pin (61). See Fig 21. Apply mo-
lybdenum disulfide spray lubricant to the gear,
allow to dry, and then apply industrial grade,
heavy duty, extreme pressure, lithium soap
grease.
Capacitor
1. Remove the cover of the capacitor (13a). See
Fig 22. Remove the flag connectors from the
old capacitor. Connect the flag connectors to
the new capacitor and replace the cover.
NOTE: The replacement capacitor includes a
