EX43-OCS
2. GENERAL DESCRIPTION
The EX43-OCS is designed to easily clean almost all types of floors. This machine has the benefits of both eccentric cleaning and orbital cleaning.
In combination with the interchangeable pads, the machine is very versatile: from carpet cleaning to (chemical-free!) stripping or polishing of parquet.
The plastic bumpers on all sides enable you to accurately work on sides.
What makes the EX43-OCS unique is the so-called Topfloor Oscillating Floor Cleaning method:
the high velocity of 1400 small movements per minute. This combined with the rotating
motion of an orbital cleaner 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.

4. INTENDED USE
The EX43-OCS floor preparation machine is developed for:
• Cleaning
• Stripping
• Polishing
• Sanding
• Levelling
• Grinding
small and medium-size 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 Topfloor of
all its responsibilities!!
Use for other purposes has not been examined (yet) by TOPFLOOR. When considering other
applications, please contact TOPFLOOR IN ADVANCE to discuss whether the machine is actually
suitable.
During operation the person stands BEHIND the machine with both hands (loosely) on the
Thandlebar.
WARNING!
The machine does NOT comply with the ATEX directive and this
version may NOT be used in any such environment!!

5.2 Wear parts.
Wear parts are components found inside the machine, which do not fall under the guarantee
due to:
1. increased contact with the product.
2. Normal wear by normal use.
The wear parts in this machine include:
• The rubber buffers
• The exchangeable pads
5.3 Vibrations of hand-arm system.
Avg. value: 2.6 m/s2,
Max. deviation: 0.3 m/s2.
(Values have not yet been measured, but taken from a similar machine.)
www.crescentindustrial.co.uk
EX43-OCS
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.
TOPFLOOR 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)
