1.9 Steps of checklist A
A-1
Inspection of manual and label
The completeness of operation and maintenance
manual is the key of safe operation. Each
equipment is supplied with a manual which is kept
in a box on the platform. The illegible or
incomplete manual is unable to provide sufficient
safe operation information.
Besides, be sure to keep all safety labels in good
conditions. The label can provide the potential
operation hazards of the machine to the operator.
Meanwhile, it also provides the operation and
maintenance information to the user. The illegible
labels cannot play the role of warning, but may
cause the dangerous operation environment.
1) Check and ensure that the operation and
maintenance manual is kept in the manual
box.
2) Check the manual for its clear writing and
completeness
Result: the manual is matched with the
model and all writings on the manual are
clear and complete.
Result: the manual is not matched with the
model and all writings on the manual are
illegible and incomplete. Stop the work of

Maintenance Manual of Elevating Work Platform

machine before replacing the manual.
3) Open the label check diagram and carefully
check if the label is illegible or complete.
Result: All labels are complete, clear and
intact.
Result: The labels are missing, illegible or
incomplete. Stop the work of machine before
replacing the label.
4) Return the manual to its original position after
the use. Notice: please contact LGMG for
manual or label replacement, if necessary.
A-2
Pre-operation inspection
The pre-operation inspection is essential to the
safe operation of machine. The pre-operation
inspection is made in the form of visual inspection
before the machine operation. This inspection is

determining if the routine maintenance
procedures are necessary.
For all inspection procedures, please refer to
“Pre-operation inspection” in this manual.
A-3
Function test
The function test is essential to the safe operation
of machine. The function test is aimed to
discovering the functional defects of the machine
before the operation. The defected machine
