5. MAINTENANCE PRECAUTIONS
5.1 PRECAUTIONS BEFORE MAINTENANCE
PUT UP A WARING SIGNBOARD DURING INSPECTION/MAINTENANCE
• When the warning sign, “DANGER. Do NOT operate”, is in place,
the machine is being inspected or under maintenance. Do not
start the engine and refrain from touching operating levers.
Disregarding the warning sign to operate the machine may give
rise to the danger of involving the maintenance personnel into the
rotating parts or movable parts of the machine, resulting in serious
injury.
• Put up additional warning signs around the machine as required.
Part number of warning signboard: 585-4714400
When this warning signboard is not used, store it in a tool box. If
no tool box is available, keep it in a holder for the instruction
manual.
TIDY UP WORKPLACE
• Clean and maintain by tidying away tools, hammers and other things that obstruct the working area
and by wiping away slippery substances such as grease and oil to assure safe operations.
An untidy workplace may cause safety hazards and result in injuries to personnel.
• Organic glass (polycarbonate) is used for roof windows. When cleaning the roof windows, please use
water and not organic solvents. If organic solvents such as benzene, toluene, methanol etc. are used,
chemical reactions such as dissolution or decomposition will occur, degrading the polycarbonate.
SELECTING A WORKPLACE
• For inspection and maintenance, select an area with flat and solid ground.
• Select such a place where no risk of landslide, rock fall or flooding is feared.
KEEP AWAY UNAUTHORIZED PERSONNEL
During maintenance servicing of the machine, never allow any personnel except the required persons.
Appoint monitoring personnel as required.
FOLLOW SUPERVISOR’S INSTRUCTION DURING TEAMWORK
Appoint a person who supervises the work and follow his/her instructions in case of machine repair or
installing/uninstalling a work device.
Unexpected accidents due to misunderstood communication between workers may occur during
teamwork.
