General description

The Excentr 30 Series is designed to easily clean edges, corners and smaller spaces. The Excentr 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 Excentr 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 electromotor 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. The Excentr 30-20+B is the cordless variant of the 30- 20+. With one powerful rechargeable lithium battery, work can take about 45 minutes. With a battery charger and 2 extra batteries, you can work continuously. 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.

Intended use

The Excentr 30 floor preparation machine is developed for:

• Cleaning
• Stripping
• Polishing
• Sanding
• Leveling
• Grinding

small and medium-sized hard and watertight floor surfaces, with the use of exchangeable pads and/or accessories that are applicable to a task. The duty cycle is 100% under normal use and in case of good workmanship. Manufactured in accordance with IP54 (30-20+B: IP44) for use with (scrub) water.
WARNING!! Any use other than that mentioned above will relieve
EXCENTR BV of all its responsibilities!! Use for other purposes has not been examined (yet) by Excentr. When considering other applications, please contact Excentr IN ADVANCE to discuss whether the machine is actually suitable.

Technical data

Sizes and weights

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.
• 30-20+ B only: the battery.

Noise emissions.
When the machine is operated the measured noise level is 72 dB(A). The measured noise level is 30-20+B: 69 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

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:

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.

Specific

• PLEASE NOTE: For each type of repair you must always disconnect the machine’s cable plug from the wall outlet. This Excentr floor preparation machine must NOT be used for cleaning floors that emit substances which pose health risks for the operator, bystanders or the environment! If used, always find out if the underfloor is suitable for treatment with the Excentr 30. When in doubt, always consult Excentr or your supplier for information.
• PLEASE NOTE: Check that the switch is in “OFF” position before you put the plug in the wall outlet!! Use caution when moving the machine on stairs / steps.
• PLEASE NOTE: The machine comes with an extension cord, which may not be extended any further with an extra extension cord. Never move over the extension cord. In case you do move or scrub over the cable by accident: Turn off the machine and remove the plug from the wall outlet. Carefully check the cable for damage. (Water can even intrude through tiny damages!)
• TAKE NOTE:  Risk of electrical shock! This machine is NOT SUITED to operate fully immersed in water This can result in life-threatening situations.

PLEASE NOTE: The machine should only be used with earthed sockets and earth leakage circuit breaker. Use of the floor preparation machine is subject to current regulations for safety and working conditions. In addition to the provisions in this manual, the generally accepted health and safety regulations for safe and professional work apply as well. Any improper operation must be avoided.
TAKE NOTE! You are working with an electrical machine and (scrub) water. Make sure that the earthing and circuit breaker function properly!! Make sure that you do not use any damaged cables!! Preferably wear shoes with rubber soles!! Within the warranty period, only Excentr B.V. certified technicians may perform repair work on the machine.

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 always secure the machine by attaching lashing straps
Excentr 30-50 and 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.
Excentr 30-20+and 30-20+B: 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

Checks before you start.
Excentr 30-20, 30-50 and 30-20+:
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 Interruptor) 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!
All Excentr 30 types:
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.

Lets go
Additional information for the 30-20+B: zie 9.4!

• 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-andforth- 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+(B): 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 centring 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 !
