Omitting the inspections after starting the engine
results in delay to notice the machine
abnormalities, and may result in bodily accidents
and machine damages.
Execute inspection in a wide location with no
obstacle. In addition, be sure to prevent people
from approaching nearby the machine.
• Inspect the equipment operation conditions,
machine travelling conditions, outrigger
operation conditions, winch winding up and
down, boom derricking, and crane operation
conditions such as extension, retraction and
slewing.
• Inspect the sound, vibration, heat and odour of
the machine, and check for instrument errors,
air leaks, oil leaks, fuel leaks, water leaks and
other bad factors. Be extra careful with fuel
leaks.
• Always repair broken part whenever an
abnormality is found.
Attempt to use without servicing may result in
unexpected bodily accidents and/or machine
failures.
