the right side of the vehicle, in front of the
hydraulic tank.
Release the four latches and remove the
cover from the air cleaner assembly. Use a
rocking motion to remove the primary air filter
and set it aside.
Use a rocking motion to remove the safety air
filter and discard the old filter. Do not leave
the intake opening uncovered. If not replac-
ing the filter immediately, cover the opening

system.

The product tank and wet system must be
flushed before winterizing. See “Flushing

Open the product tank fill valve (1), foam
marker fill valve, rinse tank valve (2), and
Roto-Flush valve to drain any remaining
water in the tanks and Roto-Flush line.

bottom half of the agitation switch to turn agi-
tation off.

blow out the wet system and booms. Cycle
the boom section switches (2) off and on sev-
eral times to purge water from around the
valves.
Disconnect the air line and close the product
fill valve.
