SERVICE MANUAL

GENERAL INFORMATION

WARNING! [RAZOR SV 17 - RAZOR E 17] – Carefully read all the instructions before carrying out any maintenance/repair procedure. – To reduce the risk of fire, electric shock, or injury, do not leave the machine unattended when it is

plugged in. Unplug the machine from the outlet when not in use and before servicing. – To avoid electric shock, do not expose to rain. Store the machine indoors. – Do not allow to be used as a toy. Close attention is necessary when used near children. – Use only as described in this Manual. Use only Kent's recommended accesso ries. – Do not use with damaged powe r su pply cable or plug. If the machine i s not working as it should, has

been damaged, left outdoors or dropped into water, return it to the Service Center. – If the supply cable or the plug is worn or damaged, it needs to be replaced by the Service Center. – Do not pull or carry the machine by the supply cable; never use the power supply cable as a handle.

Do not close a door on the supply cable, or pull the supply cable around sharp edges or corners. Do

not run the machine on the supply cable. Keep the supply cable away from heated surfaces. – Take all necessary precautions to prevent hair, jewels and loose clothes from being caught in the

machine moving or vacuuming parts. – Do not work under the lifted machine without supportin g it with sa fe t y stands. – Do not leave the machine u nattended without being sure that the machine canno t move independently. – Do not use the machine on slopes with a gradient exceeding the specifications. – Do not wash the machine with direct or pressurized water jets, or with corro sive substances. – Do not use the machine in particularly dusty areas. – While using this machine, take care not to cause damage to people. – Do not put any can containing fluids on the machine. – The storage temperature must be between +32°F and +104°F (0°C and +40°C). – The machine working temperature must be between +32°F and +104°F (0°C and +40°C). – The humidity must be between 30% and 95%. – Always protect the machine against the sun, rain and bad weather, both under operation and inactivity

condition. – Do not use the machine as a means of transport. – Do not use the machine on slopes with an inclination higher than 2%. – Do not allow the brush to operate while the machine is stat io na ry to av o id da ma ging the floor. – In case of fire, possibly use a powder fire extinguisher, not a water one. – Do not bump into shelves or scaffoldings, particularly where there is a risk of falling objects. – Do not remove or modify the plates affixed to the machine. – If parts must be replaced, require ORIGINAL spare parts from a Dealer or Authorized Retailer. – The machine must be disposed of properly, because of the presence of toxic-harmful materials (p lastic

materials, batteries, electronic boards, etc.), which are subject to standards that require disposal in

special centers (see the Instructions for Use Manual). – If the machine is used according to the instructions, the vibrations do not cause dangerous situations.

The machine vibration level is less than 98.42 in/s – This machine cannot be used on roads or public streets. – Pay attention during the machine transfers when temperature is below freezing point. The water in the

recovery tank or in the hoses could freeze and seriously damage the machine. – Use the brushes and the pads supplied with the machine and those specified in the Instructions for

Use Manuals. Using other brushes or pads could reduce safety. – When lead (WET) batteries are installed on the machine, do not tilt the machine more than 30° from the

horizontal plane to prevent the highly corrosive ac id from leaking out of the batteries. If the machine

must be tilted to perform any maintenance procedure, re move the batteries.

(2.5 m/s2) (98/37/EEC - EN 1033/1995).

WARNING! [RAZOR SV 17] – Before connecting the battery charger to the electrical mains, be sure that frequency and voltage

indicated in the Manual are compatible with the mains voltage.

– When using lead (WET) batteries, do not smoke while charging the batteries. WARNING!
