1. Unlatch the oil compartment door latches,
disconnect the vacuum hose and remove the
waste tank, remove the cap from the cleaner

the hood as shown in Figure 4- 211, and lift the
hood from the frame. Set the screws aside.
2. Disassemble the spray nozzle by unscrewing the
nozzle tip from the nozzle body as shown in Figure 4- 222 (some components are

when extended. If the vacuum head is too high, puddles of cleaner can be left on the lane.
If the vacuum head is too low, a hazy film can be left on the lane.
When the machine is turned on, the vacuum head solenoids energize to pull the vacuum
