Electromagnetic brake release instruction document. (See also “PUSHING/TOWING THE MACHINE” and “ELECTRO-
MAGNETIC BRAKE”.
Spare parts and maintenance
Contact qualied personnel or NSS Service Centres directly for any requirement regarding use, maintenance and
repairs. Only original spare parts and accessories should be used.
Contact NSS for assistance or to order spare parts and accessories, always specifying the model and serial number.
Changes and improvements
NSS focuses on constant improvement of its products and reserves the right to make changes and improvements
when deemed necessary, without having to modify the machines previously sold.
Any change and/or addition of accessories to the machine must be explicitly approved and implemented by NSS.
Operating capacity
This scrubber drier is designed and manufactured to clean (wash and dry) smooth and compact oors, in civil and
industrial environments, under veried safe conditions, and driven by a qualied operator.
The scrubber drier is not suitable for washing carpets and rugs.
Conventions
All forward, backward, front, rear, right, left indications in this manual refer to the operator sitting in the driving posi-
tion on the operator's seat.
UNPACKING/DELIVERY
Carefully follow the instructions on the packaging to unpack the Machine.
Refer to the Pushing/towing the machine section to manually push the machine.
When the machine is delivered, check that both the packaging and the machine have not been damaged during
transportation. In the event of clear signs of damage, keep the packaging and have it checked by the Courier that
delivered it. Immediately call the Courier to ll in a claim for damages.
Check that the following items have been supplied with the machine:
Technical Documentation:
• Scrubber drier instruction and maintenance manual.
• Electronic battery charger manual (if supplied).
• Scrubber drier spare part catalogue.
• Electromagnetic brake release instruction document.
SAFETY
The following symbols are used to warn of any potentially dangerous conditions. Always read this information care-
fully and take the necessary precautions to protect people and objects.
The operator’s help is essential to prevent injuries. No injury prevention plan is eective without the full cooperation
of the person directly responsible for machine operation. Most accidents occurring in a company, at the workplace or
during transfer, are caused by failure to observe the most basic safety rules.
A careful and cautious operator is the best guarantee against accidents and proves essential to complete any preven-
tion program.

PUSHING/TOWING THE MACHINE
When the drive unit cannot be used (no batteries, at batteries, faults, etc.), the electromagnetic brake must be re-
leased as follows to push/tow the machine:
• Turn lever (A1)“CLOCKWISE”as shown in the gure.
Never exceed a speed of 3 Km/h during manual pushing/towing.
• Once this operation is complete, turn lever (A1)“ANTI-CLOCKWISE”to reengage the electromagnetic brake and
restore the machine in safety conditions.
!ATTENTION!
After manually moving the machine and with the electromagnetic brake (A) engaged again, push the machine
to check that the brake is actually enabled and properly functioning.
!ATTENTION!
Never turn the machine on with lever (A1) in released electromagnetic brake position. Release the electro-
magnetic brake only for the time required to manually push or tow the machine.

PRELIMINARY OPERATIONS BEFORE STARTING THE MACHINE
!ATTENTION!
Before starting the machine, always check for any foreign bodies between the brush base (A) and the machine,
or between the squeegee (B) and the machine, that may prevent the brushes base and the squeegee from lift-
ing. This check is necessary if the machine has been turned o without lifting the brush holder base and the
squeegee; when it is turned back on, the brushes base and the squeegee automatically lift.
ELECTROMAGNETIC BRAKE
THE electric brake (1) controls braking. THE electric brake is integrated in the front in-wheel electric motor 2 drive
system and keeps the machine braked when it is o or when it is on but stopped. The electric brake is equipped with
a lever (3) to unlock and manually move the machine when it is stopped. (for example: when there is no battery). Also
see chapter:“PUSHING/TOWING THE MACHINE”.
!ATTENTION!
The machine does not brake if the electromagnetic brake is released.
NEVER USE THE MACHINE WITH THE BRAKE RELEASED.
