PRE-OPERATION INSPECTION
regulations. After any maintenance, the operator
must perform another pre-operation inspection
before conducting a pre-operation function test.
• Qualified maintenance technicians must perform
regular maintenance inspections according to the
requirements in the manufacturer’s Maintenance
Manual.
CONDUCTING A PRE-
OPERATION INSPECTION
Before starting the machine, check whether it meets the
following requirements:
• Ensure the Operation Manual and Maintenance
Manual are intact, legible and stored in the file box
on the platform.
• Make sure all labels are legible and appropriately
located.
• Check the hydraulic oil for leaks and proper oil level.
Add oil as needed. See Inspect Hydraulic Oil
Level, page 5-2.
• Check the storage battery for leaks and proper
liquid level. Add distilled water as needed. See
Inspecting the Battery, page 5-3.
• Check whether the protective device in use is
suitable for the type of work performed and
conforms to relevant technical standards.
INSPECTING PARTS
Before each use or work shift, check the following items
for any damaged, improperly installed, loose or lost
parts and unauthorized changes:
• Electrical components, wiring, cables and safety
rope
• Hydraulic hoses & fittings, hydraulic cylinder and
manifolds
• Hydraulic oil tank
• Storage battery pack and its connection
• Drive motor & reducer, slewing motor & reducer
• Boom wear pads and telescopic axle wear pads
• Limit switch and horn
• Tires and rims
• Alarms and lighting (if equipped)
• Platform（including rails, floor plate, safety lock,
brackets and entry door）
• Personal protection equipment
• Emergency control equipment
• Operation instructions, warning and control decals
• Structure and welding cracks
• Nuts, bolts and other fasteners
NOTICE
If any part is found to be damaged, improperly
installed or lost, please replace with a new part
immediately and install it correctly; if any fastener is
found detached or loose, please secure it
immediately.
INSPECTING ENTIRE
MACHINE
Inspect the entire machine for:
• Cracks in a weld joint or structural part
• Dents or other damage
• Severe rust, corrosion or oxidation
• Improper twisting of steel wire ropes, electric
cables, hoses inside the platform
• Missing or loose structural parts and key
components, including fasteners and pins for
correct positioning and tightness
• After the inspection, ensure all covers are in place
and securely locked
INSPECT HYDRAULIC OIL
LEVEL
An appropriate hydraulic oil level is vital to proper
operation of the machine. If too high, the oil will spill out
from the oil tank during machine operation; if too low,
the oil pump will have entrained air and hydraulic
components will be damaged. Performing daily
inspection of the hydraulic oil level will help you
determine if any problem exists in the hydraulic system.
Perform the following procedures with the boom in
stowed position:
1. Open the right turntable cover to make visual
inspection of the oil level in the hydraulic tank. The
hydraulic oil level should be within 80%-85% of the
oil capacity of the oil tank.
