General description.

The Excentr 30 is designed to easily clean edges, corners and smaller spaces.
The 30 can also be used to strip or grind/polish parquet floors with the use of special pads (without use of chemicals!).
The plastic bumpers on all sides enable you to accurately work in corners.
What makes the 30 unique is the so-called Excentr method: the high velocity of 2800 movements per minute. This results in an unmatched operation of the pad. The machine gives you the feeling that it ‘floats’ across the floor, which makes it easy and relaxed to handle the machine during operation.
The base of the machine is a robust stainless steel frame to which the pad holder with vibrating rubbers is attached. A robust eccentric electro motor is attached to the frame and drives the pad holder.
The 30-20+ has wheels that help to significantly improve operating convenience.
The 30-20+ allows ballast plates to be placed on the machine. This improves the effectiveness of the Excentr method and thus working speed.
To operate, a stainless steel handle with T-handlebar is installed on the frame and can be adjusted, so the handle can be set to the correct height for each height requirement.

5.2 Wear parts.
Wear parts are components found inside the machine, which do not fall under the guarantee due to:

• increased contact with the product.

• Normal wear by normal use.
  The wear parts in this machine include:

• The rubber buffers.

• The exchangeable pads.

5.3 Noise emissions.
When the machine is operated the measured noise level is 72 dB(A).
Experience shows that the noise emission of the machine depends heavily on the surface and space of operation.
This can result in situations in which the noise level is significantly higher because of ‘echo’ sounds.
Excentr therefore advises that you always have ear protection at your disposal.

From www.arboportaal.nl :
The danger of noise hearing impairment for employees begins at 80 dB (A). According to the Occupational Health and Safety Act the employer must provide hearing protection above this value.
At 83 dB(A) an employee may only work four hours without hearing protection, at which there may be no unacceptably high risk of hearing damage. In the remaining 4 hours there may no longer be any high noise levels.
It is mandatory for an employee to use ear protection if the average daily dose is higher than 85 dB(A).

Safety.

6.1 General.
Next you can see the labels that have been applied on the machine.
Make sure that the workplace is always well illuminated; possibly install extra temporary (construction) lighting to retain a clear overview.

WARNING!
Almost all accidents can be attributed to: loss of concentration,
carelessness, negligence or errors in judgment!
Work calmly and in a concentrated manner: You have been warned!!

All people who are involved with installation, commissioning, operation, maintenance and repairs must:

• have the level of knowledge and qualifications required for their task.
• have read and understood this user manual.

WARNING!!
There is immediate risk of physical injury and/or damage to machines and the environment if the machine is used by inexperienced and/or unqualified persons.
Keep observers at a safe distance when work is being carried out!!

LET OP:
Regelmatige controle en structureel preventief onderhoud verkleint de kans op storingen tijdens het werk.

Storage.

The following actions are recommended if the machine has not been used for an extended period of time:

TAKE NOTE!!
Always be careful with bearings when using a sprayer/blower to clean the machine!

• Clean the machine with a damp cloth.
• Perform maintenance.
• Possibly apply a preservative.
• Store the machine in a dry and frost-free location.

Transport.

TAKE NOTE!!
When transporting on a always secure the machine by attaching lashing straps
8.1 Excentr 30-50 en 30-20:
Wind the power cable around both cable holders on the shaft.
The machine weighs less than 20 kg and can therefore be easily carried using the handle next to the motor.
8.2 Excentr 30-20+:
The wheels under the Excentr 30-20 PLUS make it easy to move around.
The basic machine weighs ca. 17 kilos and can be easily lifted by one person (without ballast plates!).
Ballast plates increase the weight of the machine to ca. 28 kg, which means it must be lifted by two persons.

Use.

9.1 Checks before you start.
You are working with (scrub) water and a 220 V machine. Make sure that:

• The mains voltage is 220 V,
• The earth connection functions properly,
• a GFCI (Ground Fault Circuit Interrupter) is installed.

Check the cables for damage: both the short power cable as well as the extension cord! If you detect any deviations: solve these first before you start to work!
Before starting treatment with the Excentr 30, examine the floor on colour and shape retention.
Before you start, check if the correct pad for the job is attached.
When you use cleaning agents, pay special attention to the use instructions mentioned on the labels.
Use only low-foam cleaning agents that do not have any combustible components added to it and no raw materials that can pose a health risk.
Also, the use of cleaning products that contain toxic, irritating or skin- damaging substances are subject to hazards.
Cleaning agents which contain solvents that can corrode plastics, can also damage parts of the machine.

9.2 Lets go!

• Carry (30-20+:roll) the machine to the place where it is going to be used.
• Check the ON/OFF switch is switched OFF.
• Insert the extension cable in the machine plug and in a properly grounded wall socket.
• Power switch ON: the motor starts and the pad starts working.
• During work the machine can moved in all directions easily and with little force. Work in long tracks up and down, not in short back-and- forth-going movements
• Always turn the machine OFF immediately when you quit working, else the floor can be damaged.
  Take the plug out of the socket.

9.3 Only 30-20+: Extra weight.
Experience in practice shows that, under certain circumstances, the machines works better/faster if there is extra pressure on the pad.
Naturally, this is determined by the nature of the activities, the surface and the used pad. An 11 kg set of weights, which can be fixed in place using two power couplings, has been supplied to provide the extra pressure.
Installation: CAUTION: The small plates feature a centering ridge; keep this RIDGE FACING UPWARDS so the bottom side is flat against the machine. Place 4 small plates on the left and right-hand side.
The large plate can be placed on top and fixed in place using the two power couplings.

Removal: loosen the two power couplings and remove the plates. Always replace the couplings!

CAUTION!
Always protect the thread by replacing the power couplings!
