Removal (Fig. 12)
1. Empty sweeper hopper and position sweeper on a
level surface. Chock sweeper wheels to prevent sweep-
er from moving. If sweeper is attached to tow vehicle,
engage tow vehicle parking brake, stop engine and re-
move key from the ignition switch.
CAUTION
Operate all sweeper hydraulic controls to relieve
system pressure and to avoid injury from pres-
surized hydraulic oil. See Relieving Hydraulic
System Pressure in the General Information sec-
tion of this chapter.
2. Relieve sweeper hydraulic system pressure.
NOTE: The ports on the control manifold are marked to
identify hydraulic hose connections. Example: P is the
pump connection port (See Hydraulic Schematic to
identify the function of the hydraulic lines and cartridge
valves at each manifold port location).
3. Label all control manifold electrical and hydraulic
connections for assembly purposes.
4. Disconnect wire harness electrical connectors from
solenoid valves on control manifold.
5. Clean control manifold and manifold hydraulic con-
nections. Disconnect hydraulic hoses from manifold fit-
tings.
