GENERAL DESCRIPTION

The Excentr 55-35 is designed to easily clean edges, corners and smaller spaces. The 55-35 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 55-35 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 with a set of wheels 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. Extra weights have been applied on the machine to keep sufficient pressure on the pad.
To operate, a stainless steel handle with T-handlebar is installed on the frame and can be adjusted in 7 different positions, so the handle can be set to the correct height for each height requirement.
Two sturdy wheels have been installed as such that the lever action of the handle can tilt the machine backwards for easy movement.

MACHINE OVERVIEW

INTENDED USE

The Excentr 55-35 floor preparation machine is developed for:

Cleaning
Stripping
Polishing
Sanding
Leveling
Grinding
small and medium-size hard and watertight floor surfaces, with the use of the exchangeable pads and/or accessories that are applicable for a task. The duty cycle is 100% under normal use and in case of good workmanship. Manufactured in accordance with IP54 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.
During operation the person stands BEHIND the machine with both hands (loosely) on the T-handlebar.
WARNING!

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
The grip handle on the pad holder

5.3 Vibrations of hand-arm system

Avg. value: 2.6 m/s²
Max. deviation: 0.3 m/s²
Measurements made in threefold by an independent engineering agency.
5.4 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).

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 55-35, examine the floor on colour and shape retention.
– Before you start, check if the correct pad for the job is attached.
– Check that at least one set of weights is installed, but no more than six sets!
– The number of weights on the left and right-hand side of the motor must be equal!

9.2 Accessories
Turn the machine OFF and remove the plug from the wall outlet before you install/adjust accessories.
9.2.1 Liquid suction nozzle

Install the container installation for the adjustment unit.
