For battery-started machines, the start switch shall be of the type operated by a removable key or a similar device, to prevent unauthorized starting of the engine.
An engine-starting device located outside the operator zone (see Figure 1) shall only allow starting with the tines disengaged or if the machine satisfies the foot protection requirements of 5.10.2.
Compliance shall be checked by Inspection and functional test.
5.10.1.2 Engine stopping
An engine-stopping device shall be provided. The device shall not depend on sustained manual pressure for its continued operation. The stopping device can be included in the operator presence control (OPC).
NOTI An emergency stop device is not required.
Compliance shall be checked by inspection and functional test.
5.10.2 Tines In transport position
Machines that have a designated position that raises the tines such that they are not in contact with the ground shall be provided with a means to prevent unintentional contact with the rotating tines. This shall be achieved by one of the following three options:
a) when the tines are being raised they may continue to rotate but shall stop within 3 s of reaching the designated raised position0 and it shall not be possible to engage the drive to the tines when the machine is in the designated raised position (i.e. the tines are not in contact with the ground); or
b) the tines shall stop within 3 s of the operator presence control being released; or
c) the tine enclosure shall prevent Inadvertent foot contact by the operator.
Compliance shall be checked for a) by functional test, for b) by measurement according to Annex F and forc) by the foot probe test of 5.12.2.
For the prevention of inadvertent foot contact, compliance shall be checked by applying the foot probe test of 5.12.2 under the following additional conditions:
— the probe shall be applied within 600 either side of the designated starting position of the machine;
— the 600 angles shall have their vertices at the centre of rotation of the engine starting pulley.
5.11 BrakIng requirements
5.11.1 General
A means shall be provided for stopping the machine’s motion in both forward and reverse directions if the mass of a machine in its heaviest design configuration, with full fuel tanks and empty catcher (if installed), exceeds 78 kg. The tines shall be raised to their highest position.
If steering-assist brakes are also used for service brakes it shall be possible to use them in a way that they apply both brakes with equal force.
A parking brake shall be provided on machines requiring a service brake. The parking brake may be in combination with the service brake and/or make use of the tines contacting the ground. A parking brake shall be able to remain applied when the operator is not present.
An automatic parking brake, when provided, shall be activated when the operator presence control is released.
Compliance for machines requiring additional braking means (e.g. service or parking brake system), shall be tested in accordance with 5.11.2 and 5.11.3.
The machine shall be equipped with the tyres offered by the manufacturer having the least tread area in contact with the test surface.
5.11.2 ServIce brake
Test stops shall be conducted on a substantially level (not to exceed 1 % gradient) dry, smooth, hard surface roadway of concrete (or equivalent test surface), When testing a machine with separate clutch and brake control means, the clutch shall be simultaneously disengaged with brake engagement. Tests shall be carried out with the machine in both forward and reverse directions at the maximum ground speed attainable.
Using the braking system provided the machine shall stop within a distance of 0,19 m for each 1 km/h.
