3.1 Preventative Maintenance
(Table 3-1)
The complete inspection consists of periodic visual and
operational checks, together with all necessary minor
adjustments to assure proper performance. Daily
inspection will prevent abnormal wear and prolong the
life of all systems. The inspection and maintenance
schedule is to be performed at regular intervals. Inspec-
tion and maintenance shall be performed by personnel
who are trained and familiar with mechanical and
electrical procedures.
Before performing preventative mainte-
nance, familiarize yourself with the opera-
tion of the machine.
Always block the elevating assembly when-
ever it is necessary to perform mainte-
nance while the platform is elevated.
