10.4 INSPECTION AND
PREVENTATIVE MAINTENANCE
SCHEDULE
This section provides safety and other vital information
for machine operators. To extend the service life of the
machine and ensure safe operation, all necessary in-
spections and maintenance work must be completed
before the machine is put into service.
It is crucial to develop and adhere to a comprehensive
inspection and preventive maintenance program. This
manual outlines the regular inspections and mainte-
nance procedures recommended by Hunan Sinoboom
Intelligent Co., Ltd. Consult your national, regional or lo-
cal regulations for aerial work platforms. The frequency
of the inspection and maintenance must be increased
as required by environmental conditions, requirements
and frequency of usage.
Pre-delivery Inspection (PDI)
The pre-delivery inspection shall be performed by quali-
fied Sinoboom technicians.
A pre-delivery inspection shall be performed before
each sale, lease or rental delivery.
Refer to the Inspection and Preventive Maintenance
Schedule for items requiring a PDI. Refer to the corre-
sponding section of this manual to perform inspection
and maintenance procedures.
Pre-operation Inspection
A pre-operation inspection must be performed before
each start or restart of work, change of operator, and
after each maintenance operation. Refer to the pre-op-
eration inspection section of the Operation Manual for
detailed information. The Operation Manual must be en-
tirely read and understood before performing the pre-op-
eration inspection. The Operation Manual must be read
and understood in its entirety before performing a pre-
operation inspection.
Regular Inspections
Regular inspections shall be performed by qualified Si-
noboom technicians.
Regular inspections must be performed after the ma-
chine has been in service for 3 months or 250 hours,
whichever comes first, or if it has been out of service for
more than 3 months. The frequency of the inspection
and maintenance must be increased as required by en-
vironmental conditions, requirements and frequency of
usage.
The items included in the regular inspections are identi-
cal to the pre-delivery inspection.
Annual Machine Inspection
An annual machine inspection must be performed once
a year and no later than 13 months from the date of the
previous annual inspection. Hunan Sinoboom Intelligent
Equipment Co., Ltd. recommends this task be per-
formed by a factory-trained service technician, a person
recognized by Sinoboom as one who, by qualification,
certificate and training, has successfully demonstrated
the ability and proficiency to service, repair and maintain
the Sinoboom model in question.

fer to the corresponding section of this manual to per-
form inspection and maintenance procedures.

inspection and maintenance must be increased as re-
quired by environmental conditions, requirements and

sponding section of this manual to perform inspection
