1 Specifications
The SC-500 is available with different power inputs, two modes of mechanical operation and some
options regarding wet grinding. This is described in the different sections later on in this chapter.
1.1 Electrical specifications
To find the specifications that apply to your machine, check the information plate on the electrical
cabinet door.
Never connect the SC-500 to any other voltage or number of phases than described in this
specification.
The power source must be fused according to “External fuse” in this specification; also the
cables used must be marked and rated in accordance with the fuse used. Failure to comply
with the correct fuses may cause fire or injuries.

Ambient temperature range during storage -40°C to 70°C -40°F to 158°F
When using water the ambient temperature must never fall below 0°C (32°F).
The water tank should be empty during storage.
1.3 Options
The SC-500 has got two options for water supply. The standard SC-500 does not come with either
of these two options.
1.3.1 Water connection
Inside the cover of the gear barrel there is a sprinkle system connected to an external water
connection. The water connection comes with its counterpart and fits a standard ½ inch hose. At
the connection that is fitted near the handle there is a tap to adjust the flow.

1.3.2 Built in water tank
The cover of the gear barrel is configured in the same manner as with the previous option but
instead of an external water connection the machine features a 18 l built in water tank
The flow of the water is controlled by a knob on the right hand side of the machine.
The operation of the knob is described in “4.4 Water flow”.

Figure 1-2 SC-500PD with water tank
1.4 Tools
The machine must be equipped with tools approved by Scanmaskin Sweden AB before
operation.
See “9Grinding ” for information about available tools and “4.12 Changing tools” for
information about how to change the tools.
The tools are fitted using the Snap-On system for easy fitting

1.5 Range of application
SC-500 is exclusively designed to process horizontal surfaces. SC-500 must not be used for
other purposes than stated in this user guide. The manufacturer will not be liable for
damage or injury resulting from incorrect usage of SC-500. Failure to follow the
directions in this user guide will void the warranty.
Typical applications
Removal of old coatings, carpets, putty from hard surfaces
Removal of undulated concrete surfaces
Preparation of the surface for coatings
Polishing of the surface
Removal of coating defects
Removal of glue residues
1.6 Scope of supply
The following parts are included with the standard SC-500 grinding machine:
Key to electrical cabinet
Socket key for adjusting the handle
User guide
If the machine has got a water connection, the counter part for the connection will be included and
fit in the water connection near the handle.
Machines sold outside of Europe will be either equipped with a local standard connector for the
power inlet or the mating connector will be included and fitted at the main power inlet.
Read “2.6 Electrical safety” before connecting any included connectors.
