Construction

8.5.2. Both towed and integral type machines driven by

power take-off should be equipped with adequate shielding for the

part of the power line that is exposed. This shielding should pre-

vent the operator from coming into contact with positively driven

rotating members of the power line.

8.5.3.

The shielding of the power-driven line, including

all yokes and joints, should provide adequate protection during

turns under load.

8.5.4. When the casing rotates with the shaft, it should be

so designed and

fitted

that it will stop independently of the shaft on

contact with persons or their clothing.

8.5.5. At the machine end of the shaft (the power input to the

machine), the shield may include a casing that completely encircles

the shaft and overlaps the casing fitted on to the shaft

itself,

so

that no part of the shaft, couplings or clutches is exposed under

any operating conditions.

8.5.6. The shield should—

(a) be free from protuberances;

(b) cover the knuckles at any angle assumed by the universal

joints during operation; and

(c) not present a pinch point during articulation.

8.5.7. Where integral type implements driven by power

take-off are of a design requiring removal of the tractor master

shield, such implements should also include adequate protection

for the portion of the tractor power shaft that protrudes from the

tractor.
