DESCRIPTION:
Linde Electric Lift Truck Series 336 02 Explosion Protected E20 E25 E30 Service Training Manual
GENERAL INFORMATION :
This training course documentation is supplementary to the already existing training manual for the non- explosion-protected version of the electric tmcks of BR 336-02 and contains only those sections which are relevant with regard to explosion protection. For this reason, certain sections are not included in this manual.
INSTRUCTIONS
- All maintenance and repair activities with respect to explosion-protected trucks may only be carried out in areas without potentially explosive atmospheres.
- Explosion-protection measures may never be changed in a way which might affect their function. Changes of the classification with regard to the level of explosion-protection are not allowed either.
- All works must be carried out by qualified, Linde-authorized persons (specialists) who are familiar with the rules and regulations in the field of explosion protection.
- Never change the terminal assignment of the terminal strips. since a different assignment is not allowed. Lighting devices etc. which are installed at a later stage must be connected in keeping with the circuit diagram.
- For all further instructions and rules in this context. please refer to the “Ordinances and Regulations for Linde Explosion-Protected Trucks to Directive 94/ 9/ EC”.
