GENERAL INSTRUCTIONS
Specic warnings and cautions to inform about potential damages to people and machine are shown below.
DANGER!
Before performing any maintenance, repair, cleaning or replacement procedure disconnect the battery–
connector and remove the ignition key.
This machine must be used by properly trained operators only. Children or disabled people cannot use this–
machine.
Keep the battery away from sparks, ames and incandescent material. During the normal operation explosive –
gases are released.
Do not wear jewelry when working near electrical components.–
Do not work under the lifted machine without supporting it with safety stands.–
Do not operate the machine near toxic, dangerous, ammable and/or explosive powders, liquids or vapours: –
This machine is not suitable for collecting dangerous powders.
Battery charging produces highly explosive hydrogen gas. Keep the tank assembly open during battery –
charging and perform this procedure in well-ventilated areas and away from naked ames.
WARNING!
Carefully read all the instructions before performing any maintenance/repair procedure.–
Before using the battery charger, ensure that frequency and voltage values, indicated on the machine serial –
number plate, match the electrical mains voltage.
Do not pull or carry the machine by the battery charger cable and never use the battery charger cable as–
a handle. Do not close a door on the battery charger cable, or pull the battery charger cable around sharp
edges or corners. Do not run the machine on the battery charger cable.
Keep the battery charger cable away from heated surfaces.–
Do not use the machine if the battery charger cable or plug is damaged. If the machine is not working as it–
should, has been damaged, left outdoors or dropped into water, return it to the Service Center.
To reduce the risk of re, electric shock, or injury, do not leave the machine unattended when it is plugged –
in. Before performing any maintenance procedure, disconnect the battery charger cable from the electrical
mains.
Do not smoke while charging the batteries.–
To avoid any unauthorized use of the machine, remove the ignition key.–
Do not leave the machine unattended without being sure that it cannot move independently.–
Always protect the machine against the sun, rain and bad weather, both under operation and inactivity–
condition. Store the machine indoors, in a dry place: This machine must be used in dry conditions, it must
not be used or kept outdoors in wet conditions.
Before using the machine, close all doors and/or covers.–
Do not allow to be used as a toy. Close attention is necessary when used near children.–
Use only as shown in this Manual. Use only Clarke’s recommended accessories.–
Take all necessary precautions to prevent hair, jewelry and loose clothes from being caught by the machine–
moving parts.

Service Manual - FOCUS II Micro Rider 5
WARNING!
Do not use the machine on slopes with a gradient exceeding the specications.–
Do not use the machine in particularly dusty areas.–
Use the machine only where a proper lighting is provided.–
If the machine is to be used where there are other people besides the operator, it is necessary to install the–
pivoting light and the reverse gear buzzer (optional).
While using this machine, take care not to cause damage to people or objects.–
Do not bump into shelves or scaffoldings, especially where there is a risk of falling objects.–
Do not put any can containing uids on the machine.–
The machine working temperature must be between +32°F and 104°F (0°C and +40°C).–
The machine storage temperature must be between +32°F and 104°F (0°C and +40°C).–
The humidity must be between 30% and 95%.–
When using oor cleaning detergents, follow the instructions on the labels of the detergent bottles.–
To handle oor cleaning detergents, wear suitable gloves and protections.–
Do not use the machine as a means of transport.–
Do not allow the brushes to operate while the machine is stationary to avoid damaging the oor.–
In case of re, use a powder re extinguisher, not a water one.–
Do not tamper with the machine safety guards and follow the ordinary maintenance instructions–
scrupulously.
Do not allow any object to enter into the openings. Do not use the machine if the openings are clogged.–
Always keep the openings free from dust, hairs and any other foreign material which could reduce the air
ow.
Do not remove or modify the plates afxed to the machine.–
To manually move the machine, the electromagnetic brake must be disengaged. After moving the machine–
manually, engage the electromagnetic brake again. Do not use the machine when the electromagnetic brake
handwheel is screwed down.
When the machine is to be pushed for service reasons (missing or discharged batteries, etc.), the speed–
must not exceed 2.5 mph (4 km/h).
This machine cannot be used on roads or public streets.–
Pay attention during machine transportation when temperature is below freezing point. The water in the–
recovery tank or in the hoses could freeze and seriously damage the machine.
Use brushes and pads supplied with the machine and those specied in the User Manual. Using other –
brushes or pads could reduce safety.
In case of machine malfunctions, ensure that these are not due to lack of maintenance. Otherwise, request –
assistance from the authorized personnel or from an authorized Service Center.
If parts must be replaced, require ORIGINAL spare parts from an Authorized Dealer or Retailer.–
To ensure machine proper and safe operation, the scheduled maintenance shown in the relevant chapter of–
this Manual, must be performed by the authorized personnel or by an authorized Service Center.
Do not wash the machine with direct or pressurised water jets, or with corrosive substances.–
When WET batteries are installed on the machine, do not tilt the machine for more than 30° from the–
horizontal plane to prevent the highly corrosive acid from leaking out of the batteries. If the machine must be
tilted to perform any maintenance procedure, remove the batteries.
The machine must be disposed of properly, because of the presence of toxic-harmful materials (battery, etc.), –
which are subject to standards that require disposal in special centers (see Scrapping chapter on the User
Manual).
SYMBOLS SHOWN ON THE MACHINE
WARNING!
Carefully read all instructions before performing any procedure on the machine.
