WARNING
• Do not operate the machine before pre-
start checks described in this manual.
• Perform the pre-start checks on fi rm,
level surface. Begin the checks with the
platform lowered.
• If the pre-start checks reveal any
abnormalities, put an “Out of Order”
sign on the machine, and have it
repaired immediately at the nearest
designated service agent. If you use the
machine without repairing it, it may
cause a serious accident.
• If there is damage, such as cracks, on
the welds of the platform guardrail,
or on the guardrail pipes, change the
guardrail immediately.
• Damage and stains to the decals will
obstruct correct handling. Immediately
remove the stain, or change the decals.
• Make sure to perform the checks with
no load on the platform, because if
there is a load on the platform, the
checks will not be exact.
