If necessary and with great care to prevent perforating the material, it is possible to use a conventional
electric arc welding machine according to the following specifications:
o SMAW (Shield Metal-Arc Welding) process;
o Welding rod conforms to AWS (American Welding Standards) A5.4 specifications; 308L-17 type
welding rod with 3/32" diameter (2,4 mm);
o Current: - 50 amperes to 90 amperes, optimum at 60 amperes.
It is important to grind weld bead starts and stops and also to grind arc strikes from surfaces.
4. SAFETY NOTICE
This maintenance manual has been prepared in
order to assist skilled mechanics in the efficient
repair and maintenance of PREVOST vehicles.
This manual covers only the procedures as of
manufacturing date.
Safety features may be impaired if other than
genuine PREVOST parts are installed.
Torque wrench tightening specifications must be
strictly observed. Locking devices must be
installed or replaced by new ones, where
specified. If the efficiency of a locking device is
impaired, it must be replaced.
This manual emphasizes particular information
outlined by the wording and symbols:
DANGER
Directs the operator’s attention to unsafe
practices which could result in serious
personal injury or death.
WARNING
Directs the operator’s attention to unsafe
practices which could result in serious
personal injury or severe damage to the
vehicle.
CAUTION
Directs the operator’s attention to unsafe
practices where personal injury is not likely
but damage to vehicle components could
occur.
NOTE
Indicates supplementary information essential
to the proper operation of the vehicle.
Although, the mere reading of such
information does not eliminate the hazard,
understanding of the information will promote
its correct use.
4.1 DATA PLATES AND CERTIFICATIONS
Delay and confusion can be avoided by placing
