feature will automatically shut down the scrub system when the battery voltage falls to the selected threshold. The

cutoutlevelisadjustable.Thefactorydefaultsettingis20.6volts(1.72voltspercell)andthealternatesettingis21.8

volts(1.81voltspercell).Selectthecorrectcutoutlevelbasedonthebatterymanufacturer’sspecications.Itis

important to note that some maintenance-free batteries (including some gelled electrolyte cells) are capable of being

safely discharged down to 1.72 volts per cell. To select between the two cutout levels:

Selecting the Scrub Pressure Current Limits

The Clean Track

L24 uses the combined scrub brush motor current draw to determine if the scrub pressure is correct

for the selected extract mode.

• Ifthecurrentdrawgoesabovetheupperlimit,thescrubdeckliftactuatorraisesthedeckuntilthescrubmotor

current draw is within the selected range.

• Ifthecurrentdrawgoesbelowthelowerlimit,thescrubdeckliftactuatorlowersthedeckuntilthescrubmotor

current draw is again within the selected range.
