Head to Tow
Machinery Daily Checklist.
WORKING UNDER MACHINES
When working under raised machines, jacks should be used. These should be correctly positioned, and appropriate means of additional support (eg axle stands) provided.
When working on hydraulically-raised equipment (eg trailers) use props. Never rely on the hydraulics.
Ref. 'Working safely with agricultural machinery' HSE Health and Safety Executive.
Machinery Daily checks are an aid to safe towing NOT a substitute to professional maintenance
The responsibility for the provision of a safe vehicle/machine remains with the operator & the owner respectively.
