SY60C Excavator OMM
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), including (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 in accordance with
company policy.
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, 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
fluids from spraying out. See “Relieve Hydraulic System
Pressure” on page 5-29.
The engine coolant and oil in the machine may be hot
even after the engine is stopped. Wait for the cooling 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 the OFF position
unless electrical power is required for the procedure.
When removing hoses or lines, close all openings using
caps and plugs. If any fuel or oil fluids leak, clean up
immediately.
When installing high-pressure hoses, make sure they are
not twisted. Damaged hoses are dangerous and should
be replaced. Take extreme caution 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 torque. When installing protective parts
(such as guards) or parts that vibrate or rotate at high
speed, make sure they are installed correctly.
Lockout/Tagout Procedure
Perform the lockout/tagout procedure on the machine in
accordance with company policy.
Cleaning the Machine
Always use hot water and mild, nonflammable,
grease-cutting soaps or cleaning agents to clean the
machine. Never use flammable or caustic cleaning
agents.
Never use high-pressure steam cleaners to clean the
machine.
Always lubricate the machine thoroughly after cleaning to
remove any water or soap residue.
Keep the cab, windows, mirrors, and lights clean.
Fluid Systems
Adding Fluids to the Machine
When adding fluids to the machine, be aware that fluid
systems may be under pressure and hot.
Refueling
When adding fuel, shut down the machine before
removing the fuel tank cap.
Fuel spills present a hazard if not cleaned up
immediately.
Refuel only in a well-ventilated area. Never smoke or
allow open flames nearby while refueling the machine.
Never mix gasoline with diesel fuel. Gasoline is
extremely flammable and could cause an explosion.
Always allow room for the fuel to expand when filling the
fuel tank.
High-Pressure Fluid Lines
WARNING
• Never perform repairs to items while any system
is under pressure.
• Never use your hands to check or feel for leaks.
Always wear safety glasses and leather gloves,
and use a piece of wood or cardboard to check
for leaks.
• If high-pressure fluids penetrate skin or get into
eyes, seek medical attention immediately.
Failure to follow these warning can result in death
or serious injury.
Check for cracks in the lines or hoses and for swelling in
the hoses.
