RESPONSIBILITIES AFTER EMERGENCY
OPERATION:
After any emergency situation it is the responsibility
of the operator to make sure the aerial lift is repaired
and adjusted by the service department before it is
used again.
If an equipment defect is suspected, do not allow
anyone to operate the aerial lift or enter the platform.
If the bleeder ports are used they must be retightened
and the hydraulic reservoir must be refi lled. The aerial
lift must then be operated, from the lower controls,
through its full range of motion several times. Check
the hydraulic oil reservoir level and refi ll if necessary.
