The Pre-Start That Found Three Faults
It is 06:40 and you are the first on site. You carry out the daily pre-use check on the telehandler. You find: (a) the engine oil level is at the minimum mark; (b) the left rear tyre has a deep sidewall cut about 40 mm long, not through to the cord but with a bulge; (c) the boom lift cylinder has a light film of oil around the gland, with no drips on the ground; (d) the horn works but the reversing bleeper is silent; (e) the seat belt is frayed at the buckle end. The machine was used until 18:00 the previous day and the site opens at 07:00. The supervisor says 'just get on with it, we'll look at it at lunchtime.'
1. Categorise each finding and decide what the machine can and cannot be used for today.

Findings and decisions:
- (a) Oil at minimum - top up before use and investigate consumption. Not a stop item if topped up and no leak found, but record it.
- (b) Sidewall cut with a bulge - stop item. A bulge indicates structural damage to the tyre casing; a sidewall failure under load can cause loss of control or overturn. The machine must not be used until the tyre is assessed/replaced by a competent tyre fitter.
- (c) Oil film at the boom cylinder gland - monitor, but a film without drips is often acceptable; a drip is a defect. Clean it, run the machine, and re-check. If it drips, stop.
- (d) Silent reversing bleeper - stop item until rectified, because it is a required safety device for reversing, and reversing is a major cause of telehandler fatalities. The machine should not reverse in a work area without it working.
- (e) Frayed seat belt - stop item. A damaged restraint will not perform in an overturn. Replace before use.
The machine is not fit for work today. The supervisor's instruction to defer to lunchtime is not acceptable for the stop items; the operator has a duty to report defects and not use unsafe equipment. The correct action is to record the defects, isolate/tag the machine, and report to the responsible person for repair.
2. What should happen to the machine and the information flow while it is out of service?
Read the worked answer
The machine should be immobilised and clearly tagged 'Do not use - defective', with the keys controlled so no one else takes it. The defects should be written on the pre-use check sheet and reported to the responsible person immediately, with a clear list of what must be rectified before it returns to service. The supervisor should be informed in writing (not just verbally) so the decision is documented. Repairs should be carried out by competent persons, and the machine should not be released until each stop item is signed off. If the site needs a telehandler today, the correct response is to hire or borrow a serviceable machine, not to use a defective one. I would also note the reversing bleeper defect because it affects anyone working near the machine, not just the operator.
