Indirect Scrubbing Or For Very Dirty Surfaces; Post-Scrubbing Operations; Maintenance Information; Tanks - Kruger KF120B Manual Del Usuario

Scrubbing and drying in a single pass.
Prepare the machine as previously described.
Select the forward direction using the direction
lever.
Insert and turn the key.
Activate the suction motor, the brush motor and
the detergent solution supply.
Lower the brushes and the squeegee.
Use the detergent adjustment lever to regulate the
solution outlet flow (depending on advancement
speed).
Lightly press the advancement pedal and check
that all systems are working.
Fully depress the accelerator to increase the work
speed.
Adjust the maximum advancement speed and the
detergent solution flow as required.
The steering wheel is similar to a car steering
wheel: it can be used to turn the machine around
itself by steering all the way to one side. § Dur-
ing these operations, the rear of the machine
moves slightly outward: reduce the speed to avoid
brusque direction changes and impacts against
walls or other objects.
To avoid damage to the surfaces being treated, the
brush motor will stop automatically about 2 sec-
onds after the advancement pedal has been com-
pletely released.
☞ Never use the machine without the detergent
solution: the floor might be damaged.
7.7.4 INDIRECT SCRUBBING OR FOR
VERY DIRTY SURFACES
Scrubbing and drying in various passes.
Prepare the machine as previously described.
First set of operations:
Select the forward direction using the direction
lever.
Insert and turn the key.
Activate the brush motor and the detergent solu-
tion supply.
Lower the brushes.
Use the detergent adjustment lever to regulate the
solution outlet flow (depending on advancement
speed).
Lightly press the advancement pedal and check
that the brushes and solution feed system are
working.
Fully depress the accelerator to increase the work
speed.
Adjust the maximum advancement speed and the
detergent solution flow as required.
The steering wheel is similar to a car steering
wheel: it can be used to turn the machine around
itself by steering all the way to one side.
• During these operations, the rear of the machine
moves slightly outward: reduce the speed to avoid
brusque direction changes and impacts against
walls or other objects.
Allow the detergent solution to work on the dirt
according to what is indicated in the information
relative to the detergent used.
Second set of operations:
Follow the steps described in the previous section
"Direct Scrubbing" (7.8.3).
To avoid damage to the surfaces being treated, the
brush motor will stop automatically about 2 sec-
onds after the advancement pedal has been com-
pletely released.
When moving in reverse, the squeegee will lift
and suction will be deactivated automatically. After
changing direction (forward direction), the squee-
gee and the suction will automatically return to
their previous condition.
☞ Never use the machine without the detergent
