GENERAL DESCRIPTION

The Excentr 30-20 PLUS is a further development of the 30-20.
The machine has been improved in two ways:

BALLAST: Ballast plates can now be placed on the machine.
This increases the efficiency of the Excentr method and the operating speed.
WHEELSET: The addition of a wheelset has significantly increased operating comfort.

The 30-20 PLUS is – similarly to the standard 30-20 – designed for easily cleaning floors along the edges, and in corners and smaller spaces. After fitting special pads, these machines can also be used for (solvent-free!) stripping or sanding/polishing parquet floors.
The plastic surround bumper makes it possible to work in tight corners. These floor treatment machines are unique because of the Excentr method: the high number of oscillations of 2,800 a minute. This makes the effect of the pads unrivalled.
The machine is easy to use and requires no effort, because it is as if it hovers over the floor. The basis of the machine is a robust, sturdy stainless steel frame on which the pad holder with oscillating rubbers is attached. A large-size eccentric electric motor that drives the pad holder is mounted on the frame. When in operation, the machine is guided over the floor on a wheelset by pushing a stainless steel shaft ending in a T-handle that can be adjusted to suit any height.

MACHINE OVERVIEW

Excentr 30 20 Single Disk Scrubbing Machine - OVERVIEW

INTENDED USE

The Excentr 30-20 PLUS floor treatment machine is designed for:

Cleaning
Stripping
Polishing
Sanding
Levelling
Buffing

small and medium-sized hard and water-resistant floor surfaces using task- specific pads and/or accessories. The duty cycle is 100% for normal professional use. Machines fitted with an IP54 plug can be used with (scrubbing) water.

WARNING!
Excentr B.V. disclaims all responsibility in advance for damage caused as a result of any use other than described above!!
Excentr has – not yet – tested and approved the use of the machine for other purposes. With respect to other possible uses, contact Excentr IN ADVANCE to discuss whether the machine is suitable. When working, the operator stands BEHIND the machine loosely holding the T-handle.

WARNING!
These machines do NOT comply with ATEX requirements and may NOT be used in an ATEX environment!!

According to information given on the website www.arboportaal.nl the risk of employees suffering hearing loss starts at exposure to a noise level of 80 dB(A). Under the Working Conditions Act, the employer must provide hearing protection if the local noise level exceeds this value. Employees may only work in an environment with a noise level of 83 dB(A) for four hours without hearing protection, there must not be an unacceptably high risk of hearing loss and they may not be exposed to high noise levels during the following four hours. Employees are obliged to wear hearing protection if they are on average exposed to a noise level of 85 dB(A) on a daily basis

TECHNICAL DETAILS

5.1 Specifications

Dimensions (lxwxh):	40 x 32 x 115 cm
Weights:	30-20 PLUS basis: 17 kg

5.2 Parts subject to wear
Machine parts subject to wear are not covered under the warranty conditions due to:

additional contact with the product or
normal wear and tear during use
The parts of this machine that are subject to wear are:
• The oscillating rubbers
• The pads

5.3 Noise emission
The measured noise level of the machine when in operation is 72 dB(A). Test results show that the machine’s noise emission when in operation depends largely on the surface on which and the space in which it is used. Spatial echo can lead to significantly higher noise levels. In these situations, Excentr advises making hearing protection permanently available.

TRANSPORT

The integrated wheelset makes the Excentre 30-20 PLUS easy to move.
The basic machine weighs approximately 17 kilos (without ballast plates!) and it can be lifted by one person. With ballast plates fitted, the machine weighs approximately 28 kg and has to be lifted by two people.

GETTING DOWN TO WORK!

9.1 Preliminary checks
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 43, 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 Getting down to work!

Move the machine to the location where it will be used.
Adjust the handle to a suitable working height and make sure it is locked properly in position!
Check whether the switch is set to OFF.
Unwind the extension cable (if used) completely and insert the machine’s plug into an earthed power socket.
Push the switch to ON position. The motor will start and the pad will start to work.
While working the machine, you can easily push it around in any direction without requiringa large amount of force. Work in straight lines, not by moving the machine from left to right.
Always switch off the machine immediately after stopping work so you do not damage the floor. Remove the plug from the power socket.

9.3 Ballast plates – Additional weight
We know from practical experience that the machine works better/faster under specific circumstances with additional weight pushing down on the pad. This obviously depends on the type of work, the surface and the pad in use. An 11 kg set of ballast plates that can be attached using two star knobs is supplied with the machine for this purpose. The small plates have centering boss that has to lie ABOVE the underside of the machine. Place four small plates on the left and right of the machine. The large plate can be laid on top and secured in position with the two star knobs.

MAINTENANCE

ATTENTION!
Regular inspections and scheduled preventive maintenance reduce the chance of malfunctions during operation.

10.1 Lubricants
No specific lubricants are recommended for the EXCENTR 30 series.
10.2 Maintenance schedule
10.2.1 Daily (before starting work)

Check all cables for damage. Repair damaged cables before starting work!
Check the pad for wear. A worn pad reduces the operating speed.
After using the machine with chemical cleaning agents, wipe the machine down with a damp cloth to prevent corrosion of the stainless steel components.
Check for loose nuts and bolts.

10.2.2 Monthly

Check whether the plate under the pad holder still has enough grip to hold the pad in position.
Check the oscillating rubbers for cracks. Have cracked oscillating rubbers replaced!

10.2.3 Yearly

Have the machine tested in accordance with the compulsory occupational health and safety test (NEN 3140) for electrical machines.

10.3 Replacing a pad
If the operating speed drops, or the machine’s performance declines, the pad has probably accumulated a large amount of dirt or is worn and it has to be cleaned or replaced. The pad is attached to the Excentr plate with Velcro.
Proceed as follows:

Switch the machine off.
Remove the plug from the power socket.
Put the handle in the highest position.
Tip the machine backwards so that the handle rests on the ground and the pad is vertical.
Pull the pad off the pad holder.
Place the new pad carefully on the pad holder and push it firmly into position.
Return the machine to the upright position.
Put the handle back in the preferred position.
Insert the machine’s plug in the power socket.
Switch the machine on and continue working.

TROUBLESHOOTING

The machine will not start:
• Check the earth leakage.
• Check the supply voltage.
• Check the cables for damage.
• Contact your supplier.
The machine makes a rattling sound. STOP IMMEDIATELY!!
CHECK THE MACHINE BEFORE CONTINUING WORK!!
