General rules
To avoid the accidents
The majority of accidents that occur in the workshop are caused by lack of observance of a few simple and fundamental rules of prudence and safety. For this reason the majority of the cases can be avoided: all it takes is to forsee the possible causes and to act accordingly with the necessary caution and prudence. With any type of machine, however well developed and constructed, it is not possible to absolutely exclude every eventuality of an accident. A careful and prudent mechanic is the best guarantee against accidents. The scrupulous observance of only one elementary safety rule would be more than sufficient to avoid many serious accidents
Safety rules
Generally
To carefully follow the procedures laid down for maintenance and repair.
Never carry out cleaning, lubrication or maintenance with the battery connected, except in the cases
prescribed
- Do not wear rings, wrist watches, loose or untied articles of clothing or dangling items such as, ties, torn garments, scarves, waistcoats or blouses with opened zip fasteners which could get entangled in moving parts. It is recommended instead to use approved protective clothing such as helmets, anti-slip shoes, gloves, safety glasses. Do not perform any repair or maintenance work on the machines with people on the seat, except the usual operator to provide assistance to carry out the work.
- Do not operate the truck in any other position than seated in the driver’s seat. Verify that there is no pressure in the hydraulic circuits before removing plugs and covers. Refer to the instructions provided on the subject in the present publication. All maintenance work must be carried out with the maximum care and attention.
- The stepladders and platforms used in the workshop or in the field must be of construction conforming to the current safety rules and regulations. Label all the controls to signal that an intervention is in progress. Use blocks or straps constructed of suitable material to support the truck should the truck or any parts of it be required to be raised up.
