MAINTENANCE SAFETY
SANY cannot foresee every circumstance that might involve a hazard in operation or maintenance. Therefore, the
hazard alerts in this manual and on the machine may not include all possible safety precautions.
Make sure all procedures and actions can be safely performed without damaging the machine or causing injury.
When unsure about the safety of a procedure, contact a SANY dealer.
Before carrying out any repair, read all the safety messages on the machine associated with the procedure.
Wear and use the proper personal protective equipment (PPE). PPE includes (but not limited to) safety shoes, a
hard hat, gloves, and goggles.
When carrying out any operation with two or more workers, always agree on the operating procedure before
starting.
Perform the lockout/tagout procedure before servicing the machine.
Always inform fellow workers before starting any step of the operation.
Keep all tools in good condition, know how to use them, and use the correct ones. Thoroughly check all tools
before starting any procedure.
Park the machine on a hard, level surface, lower the work equipment, move the hydraulic lockout control lever to
the locked (closed) position, and block the tracks to prevent the machine from moving before performing any
maintenance or repairs.
Before disconnecting or removing components of the hydraulic system, relieve the system pressure to prevent
hydraulic fluid from spraying out. See “Relieve Hydraulic System Pressure” on page 5-73.
The engine coolant and oil in the machine may be hot even after the engine is stopped. Wait for the engine coolant
and oil systems to cool before working on them.
When checking the machine with the engine running (e.g., measuring oil pressure, revolving speed, or
temperature), take extreme care to avoid rotating or moving parts.
Turn the battery disconnect switch to OFF unless it is needed for the procedure.
NOTE:
The electrical circuit remains active to a few components even when the battery disconnect switch is
in the OFF position.
When removing hoses or lines, close all openings using caps and plugs. If any fuel or fluids leak, clean up
immediately.
When installing high-pressure hoses, make sure they are not twisted. Damaged hoses are dangerous and should be
replaced. Be extremely careful when installing hoses for high-pressure circuits. Make sure fittings are correctly
installed and tightened.
When assembling or installing parts, always tighten them to the specified torques. When installing protective parts
(such as guards) or parts that vibrate or rotate at high speed, make sure they are installed correctly.
