DUST CONTROL SWITCH (See Figure 11)

The Dust Control Switch is a two position switch located on the instrument panel next to the filter shaker switch. The switch controls the vacuum fan in the dust control system.

To turn on the dust control system for “NORMAL” sweeping, press on the top portion of the switch. To turn off the dust control system for sweeping in wet conditions, press the lower portion of the switch. This will prevent the filter from being damaged by water pickup while sweeping.

SCRUB DECK SWITCH (See Figure 12)

The brushes switch is located on the console to the left of the steering wheel in the “SCRUBBING” section. This switch in the position marked “LOWER” will lower the scrub deck and activate the three scrub brushes. This switch in the “RAISE” position will stop the brushes from rotating and raise the scrub deck.

NOTE

Lowering the scrub deck will not start the brushes rotating. The machine must be moving to engage the scrub brushes. If the machine stops moving for 2 seconds or more, the brushes will automatically stop rotating until the machine starts moving again.

SQUEEGEE SWITCH (See Figure 13)

The squeegee blade switch is located on the console to the left of the steering wheel in the “SCRUBBING” section. This switch in the position marked “LOWER” will lower the squeegee and activate the squeegee vacuum. This switch in the “RAISE” position will stop the squeegee vacuum and raise the squeegee. If the machine is put in reverse, a switch is automatically activated to raise the squeegee if in the lowered position as well as stop the vacuum.

The switch has a center position which will raise the squee- gee but allows the vacuum to continue running, retrieving the water left in the squeegee recovery hose. This prevents water from dripping on the floor with the squeegee “UP.”
