PRE-OPERATION INSPECTION
CONDUCTING A PRE-
OPERATION INSPECTION
Before starting the machine, check whether it meets the
following requirements:
• Ensure the Operation Manual and Maintenance
Manual are in good condition, legible and stored in
the storage compartment on the platform.
• Make sure all labels are legible and appropriately
located.
• Check for hydraulic oil leaks and proper oil level.
Add oil as needed. See
Inspect Hydraulic Oil
Level, page 5-2 .
• Check 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 matches
the type of work performed and conforms to relevant
technical standards.
INSPECTING PARTS
Check the machine for any damaged, improperly
installed, loose or lost parts and unauthorized changes:
• Electrical components, wirings and cables
• Hydraulic hoses & fittings, hydraulic cylinder and
valve block
• hydraulic tank
• Storage battery pack and its connection
• Drive motor & brake
• Turntable swing motor and hydraulic pump
• Boom wear pads and telescopic axle wear pads
• Limit switch and horn
• Tire and rim
• Alarms and lighting (if equipped)
• Guardrail and entry gate
• Structure and welding cracks
• Nuts, bolts and other fasteners
NOTICE
If damaged parts, incorrect installation or missing
parts are discovered, please replace immediately
and install correctly; if the fasteners are found
detached or loose, please secure immediately.
INSPECTING ENTIRE
MACHINE
Inspect the entire machine for:
• Control switches and handles on platform controller
and turntable controller in neutral position
• Cracks in a weld joint or structural part
• Dents or other damage
• Severe rust, corrosion or oxidation
• 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
Ensuring 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 suction air and damage hydraulic
components. Performing daily inspection of the
hydraulic oil level will help you determine if a problem
exists in the hydraulic system.
Perform the following procedures with the boom in
stowed position:
1. Open the left turntable cover to make visual
inspection of the sides of hydraulic tank, the
hydraulic oil level should be within the marking
range of oil level indicator.
Figure 5-1
2. Ensure the hydraulic tank body and its connections
are free of leaks.
3. Add oil as needed. Never overfill the tank.
