EN 704:1999+A1:2009 (E)
3 Safety requirements and/or measures
3.1 General
The machinery shall comply as appropriate with EN 292 for hazards which are not dealt with and especially
with annex A of EN 292-2:1991/A1:1995 when EN 292 does not give precise requirements.
Unless otherwise specified in this standard, the machine shall comply with the requirements of prEN
1553:1998 and with tables 1, 3, 4 and 6 of EN 294:1992.
3.2 Requirements for all types of balers
3.2.1 Protection against hazards related to moving power transmission parts
To ensure protection against hazards related to accessible moving power transmission parts, the machine
shall be fitted with fixed guards (according to 3.22.1 of EN 292-1:1991).
When frequent access is foreseen, the machine shall be fitted with guards needing a tool for their opening.
These guards shall remain attached to the machine when opened (for example by means of hinges) and
automatically lock in the closed position without the use of a tool.
If this type of guard is not used, the machine shall be fitted with:
 interlocking movable guards (according to 3.22.4 of EN 292-1:1991); or
 movable guards fitted with a device which prevents their opening so long as the parts are moving.
3.2.2 Drawbar
When the drawbar has separate positions, for transport and for working, it shall be provided with a mechanical
or hydraulic locking device that requires an intentional action to change from transport to working position and
from working to transport position (e.g. pin, latch or hydraulic cylinder). When a hydraulic device is used, the
drawbar shall remain locked in position if the hydraulic circuit fails.
3.2.3 Pick-up device
The protection of exposed persons against unintentional contact with any of the accessible moving parts at
the front and at the sides of the pick-up device shall be ensured by a combination of barriers and fixed parts of
the machine. The projection on a horizontal plane of these protective devices shall be continuous (see figures
1 and 2).
When the pick-up device is in the working position, these barriers shall be:
 a minimum of 230 mm in front of the most forward point of the tine path and at a height h of between 500
mm and 1 000 mm above the ground (see figure 1);
 a minimum of 150 mm from the sides of the tine path at a maximum height above the ground of 500 mm
(see figure 1). If the tine path is totally covered by a part of the machine when viewed from the side (see
figure 2), this barrier is not required.
NOTE 1 The strength of the barriers will be dealt with within prEN 1553.

For balers capable of forming bales with a cross section of 0,2 m or greater:
 it shall be possible to immobilize the flywheel to avoid unintentional movement after it has stopped (for
example by means of a brake or a mechanical restraining device);
and
 when the flywheel is positioned in such a way it is located above the crop flow when picking, the lower
part of the flywheel may be exposed, providing the flywheel has a smooth surface and the upper part is
guarded for at least 2/3 of the flywheel diameter measured vertically from the top.
3.3.2 Driving mechanism for the plunger
The connecting rod and crank mechanism shall be guarded according to 3.2.1. The side guard shall cover the
extreme path of the crank when viewed from the side. If the guard of the rod and crank mechanism is open
underneath, a distance of at least 25 mm shall be provided between the rod and the crank mechanism and the
guard; this 25 mm clearance shall extend from the edge of the guard for a distance of at least 120 mm (see
figure 4).
If fixed parts of the baler are located directly below the crank path at a distance d less than 300 mm from it,
then the side guard shall extend below these fixed parts (see figure 4).
