KNOW YOUR MACHINE
FUNCTIONAL DESCRIPTION OF CONTROL PANEL:

The controls on the Convertamatic / BA 625 series were designed with

one touch operation

in mind. For single pass scrubbing the user can simply

depress one switch and all systems on the machine will be ready to go. For most single-pass scrubbing operations, the operator should only need
to use the middle switches on the control panel. These are the Scrub System OFF and Scrub system ON switches.

Scrub OFF Switch (H)

- Pressing this switch when the unit is in a scrub mode will cause the following to occur:

• The scrub brushes will turn off and the scrub deck will be raised to the up position
• The solution

ow will be stopped

• The

rst time that this switch is pressed, the vacuum system will NOT be turned off. This is so that any remaining water may be picked up without

having to turn the vacuum back on. If this switch is pressed a second time (pressed after the scrub system has been turned off) the vacuum will shut
of after a 10 second delay.

Scrub ON Switch (I)

– If the scrub system is off, pressing this switch once will cause the following to occur:

• The scrub system will be enabled with the scrub pressure set to the regular setting and the scrub deck will be lowered. Note press twice for the
heavy scrub pressure mode and hold this switch for 5 seconds to enter the extreme scrub mode.
• The vacuum system will be enabled.
• The solution system will be enabled.
• As soon as the throttle (operator drive paddle) is moved from the neutral position the scrub brushes will start turning and the vacuum will turn on. If
the direction is forward the solution

ow will start. If the direction is reverse, the solution

ow will be stopped. If the scrub system is already enabled

when this switch is pressed, the scrub pressure will increase to the heavy scrub mode. If the switch is held for 5 seconds the pressure will change
to the extreme scrub mode. At the same time the panel display will show the correct changed scrub pressure setting.

Wand Switch (E)

– This switch is used when an external vacuum/scrub wand is used. Pressing this switch will turn the vacuum on continuously

without regard to the throttle position. If the scrub system was on it will be turned off. This includes turning off the scrub brushes and turning the
solution

ow off (to the scrub deck).

NOTE:

automatic shutoff of the vacuum motor when the recovery tank is full is disabled when the wand is

enabled.

Key Switch (A)

– Main power switch

Vacuum Switch (C)

– This switch is used to turn the vacuum system on or off. Pressing this switch will alternate between on and off. The vacuum

will only turn on when the throttle is moved from the neutral position. It will remain on for 10 seconds after the throttle returns to neutral.
The vacuum also has an automatic shutoff feature that will turn the vacuum and scrub systems off if the recovery tank becomes full.

Solution Switch (B)

- This switch is used to turn the solution system on or off. Pressing this switch when the scrub system has been activated will

alternate between on and off. The solution

ow will only turn on when the throttle is moved from the neutral position in the forward direction. The

solution

ow will turn off if the throttle returns to neutral or is moved to reverse. Pressing this switch when the scrub system is off will momentarily

turn the solution

ow on to allow pre-wetting of the scrub brushes.

Chemical Switch (F)

– Pressing this switch will turn on or off the chemical option. See the main programming options in this manual to select

(activate) the onboard chemical distribution system.

Extended Scrub (Recycle) Switch (G)
