PRE-OPERATION INSPECTION
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 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
Before each use or work shift,check the machine for
any damaged, improperly installed, loose or missing
parts and unauthorized changes:
• Electrical components, wiring,cables and safety
ropes
• Hydraulic hoses, fittings, cyinders and
counterbalance valves
• Drive motors
• Wear pads
• Tires and wheels
• Limit switches, alarms and horn
• Beacons and indicator lights (if equipped)
• Bolts, nuts and other fasteners
• Brake releasing
• Safety arm
• Scissor arm pins and fasteners
• Platform joystick
• Outriggers (if equipped)
• Hydraulic tank
• Platform（including rails, floor plate, safety lock,
brackets and entry door）
• Generator (if equipped)
• Personal protection equipment
• Emergency control equipment
• Operation instructions, warning and control decals
NOTICE
If any part is found damaged, missing, or improperly
installed, please immediately replace with a new one
and install correctly; if any fastener is found detached
or loose, please tighten immediately.
INSPECTING ENTIRE
MACHINE
Inspect the entire machine for:
• Cracks in welds or structures
• Dents or other damages
• 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
• Ensure the rails are installed with bolts tightened.
NOTICE
If the machine has to be inspected with platform
raised, please be sure the safety arm is properly set
up.
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.
