MOTOR & CAPACITOR
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.
WARNING
NOTE: Refer to Fig 20 except where noted.
1. Remove the sprayer’s shroud and the lift han-
dle (2).
2. Disconnect the hose (26) from the displace-
ment pump.
3. Remove the screws (51 & 8b). Pull the drive
housing assembly (A) off the motor housing
(B).
4. Remove the screws (8c) and pull the motor
housing (B) off the motor (13).
5. Drive out the pin (61). Remove the gear (60).
6. Remove the pressure control cover (7). Dis-
connect the motor leads. See Fig 21.
7. Unscrew the nut on the conduit (13f). Unscrew
the bushing (91). See Fig 21. Gently pull the
conduit away from the pressure control and
pull the leads out one at a time.

Always pull the motor leads one at a time to
avoid loosening the terminals.

damage. Replace if necessary. Secure the
gear with the pin (61). Apply molybdenum dis-
ulfide spray lubricant to the gear, allow to dry,
and then apply industrial-grade, heavy-duty,
extreme-pressure, lithium-soap grease.
NOTE: A circuit board (13b) is included with a
new motor. See page 18 for installation.
Capacitor
1. Remove the cover of the capacitor (13a). See
