7.1.1 DAILY INSPECTIONS
EACH DAY PRIOR TO USE AND DURING OPERA-
TION CHECK:
(1) Pneumatic :
a) Check oil level in air preparation unit.
b) Check condition of all air hoses and connectors,
if damaged DO NOT USE THEM.
c) Check all air line connections for locking pins
and strain relief. Be sure all relief devices are
properly connected and air line is supported by
work platform and not the hoist.
d) Check motor function. If it makes unusual noises,
starts sluggishly or will not start, before using
refer to TROUBLESHOUTING page 19/20.

to lower the platform to check that the BSO
secondary brake holds the load. A loop should
form as shown in Fig. 35, which means the
BSO secondary brake is supporting the load.

window (d3) that the centrifugal weights are
rotating (Fig. 36).
