RootsScrub E4550 ES
Wet mode
The wet scrubbing procedure is used to scrub the escalator steps
as a final cleaning operation.
Wet Scrubbing:
= Brushes: Use only Nylon brushes for wet mode.
= Install the debris tray.
= After positioning the machine on the escalator, ensure that
the parking brake is engaged.
= Ensure that the motion of the escalator is directed towards
the machine.
= Switch the machine to WET mode using the knob on the
control panel.
= Ensure that the debris tray is installed in the machine.
= Upon switching it can be noticed that the water is now sprayed
from the forward nozzles located on top of the brush head.
= The onboard vacuum system will then suck the dislodged
debris into the dirty water tank.
Continue cleaning till the escalator has completed two rounds for
better cleaning results.
The suction will switch off when the dirty water tank reaches its
maximum capacity or if the fresh water level gets empty.
The water flow to the front spray nozzles are timed for optimal
machine performance. It is factory set and should not be
tampered.
Note:
Ú In this mode water will not be sprayed inside the suction hose
assembly.
Ú
Also check the flow of water from the nozzle at the first start of
the day.
Note:
â Before switching to wet mode operation,
ensure that the debris tray and brush head
are cleaned.
â DO NOT use the wet mode for more than 3 minutes at a
stretch, it may cause water to be collected on the escalator
step.
â In case the suction and water systems are not working, it
might be possible that the dirty water tank is full or the fresh
water tank is empty.
Note: Water pressure is factory set.
