Introduction
This European Standard covers
Circular saw machines standing on the floor and
Circular saw machines installed in a cutting line.
The extent to which hazards are covered is indicated in this European Standard. For other hazards which are not
covered by this European Standard, machinery should comply with EN 292 where applicable.
1 Scope
This European Standard specifies requirements for the design and manufacturing of circular saw machines (see
Figures 1 and 2).
The machines covered by this European Standard are used to cut bone and meat.
The circular saw machines covered by this European Standard do not include circular saw machines for processing
of wood and similar materials and the requirements of EN 1870-1 do not apply.
Circular saw machines for domestic use are not included in this European Standard.
This European Standard applies only to machines which are manufactured after the date of issue of this European
Standard.
This European Standard covers the following types of machines:
Circular saw machines with a feed table and a fixed product pusher
The distance „A“ from the floor to the top surface of the feed table is from 800 mm to 1050 mm. The saw blade
diameter is between 350 mm and 400 mm (see Figure 1).
Circular saw machines installed in a cutting line (e.g. conveyor belt or roller conveyor), e.g. with a protective
component which can be lifted on the feed and discharge side. The saw blade diameter is between 350 mm
and 400 mm (see Figure 2).

Figure 1 — Circular saw machine with machine base Figure 2 — Circular saw machine in cutting line
Circular saw machines comprise a machine base, a fixed, foldable feed table, a product pusher, a protective hood
which can be lifted, a saw blade, a drive and electrical components, depending on machine type.
Circular saw machines with a machine base can be wheel-mounted (see Figure 1).
The intended uses of the machines are described in clause 7.
On floor-type circular saw machines (see Figure 3) the product to be cut is placed by hand onto the feed table and
pushed against the cutting zone of the saw blade by means of the product pusher and sawed.
On circular saw machines which are installed in a cutting line (see Figure 4) the product to be cut is pushed by
hand via the conveyor belt or roller conveyor against the cutting zone of the saw blade and sawed.
