MACHINE OPERATION
4-17 SY500H Excavator OMM
Machine Warm-up
WARNING
• In case of emergency, irregular engine operation,
or other faults, turn the key switch to OFF or use
the emergency stop switch to stop the engine.
• Do not operate the machine immediately after
starting the engine. Insufficient warm-up of the
machine and hydraulic oil may cause slow
control response or abrupt movement during
operation, resulting in serious accidents.
Warm-up is especially necessary in cold areas.
Failure to follow these warnings could result in
death or serious injury.
Do not operate the machine immediately after starting the
engine. Allow the machine and hydraulic system to warm
up. Complete the following warm-up procedures:
1. De-activate the auto-idle mode after starting the
engine. See “Auto-idle” on page 3-21. Adjust the
throttle so the engine runs unloaded at 1400 rpm for
5 minutes.
2. Adjust the throttle so the engine runs at 1500 rpm,
then slowly operate the bucket for 5 minutes.
3. Adjust the throttle so the engine runs at a high rpm,
then operate the boom, arm, and bucket for 5 to 10
minutes.
Repeat all procedures several times and stop the
warm-up process. Check the monitor and indicators for
normal operating readings after the warm-up process.
Idling the Engine
Allow the engine to idle until the engine temperature
reaches 140°F (60°C) before beginning operation.
Idling the engine for long periods wastes fuel and causes
carbon formation, oil dilution, formation of lacquer, or
gummy deposits on the valves, pistons, and rings, and
rapid accumulation of sludge in the engine.
Engine Shutdown Procedure
1. Park the machine on a flat, level surface away from
people, traffic, and other machines.
2. Lower the work equipment to the ground.
3. Run the engine at low idle (approximately 1050 rpm)
for 5 minutes.
NOTE: Except for emergencies, never shut down the
engine while it is running at high speed. Stopping
the engine at high speed can damage the
machine, personal property, and the environment,
or cause the equipment to operate improperly.
4. Turn the key switch to OFF and remove the key.
5. Turn the battery disconnect switch to OFF.
Cold Weather Operation
The following recommendations are for operating SANY
machines in low temperatures (below 32°F [0°C]):
NOTE: See “Key Switch” on page 3-13 for details on
using the key switch to preheat the engine for
cold-weather starting.
NOTE: See “Cold Weather Start” on page 4-16 for cold
weather starting procedures.
• The correct grade of oil for the ambient temperature
must be used in the crankcase. Diesel fuel must have
a pour point of 10°F (-12°C) less than the lowest
expected temperature.
• This machine must have appropriate hydraulic oil,
lubricants, and other auxiliary items required for
operation in very low temperatures (below 32°F [0°C]).
Individual machine functions should be operated to
provide they are sufficiently warmed prior to performing
work.
• Only competent operators who possess the skill,
experience, and dexterity to provide smooth operation
should operate the machine at full-rated capacities in
temperatures between 0°F and -40°F (-18°C and
-40°C). Shock-loading must be avoided.
Cold-weather operation requires additional precautions:
• Avoid touching metal surfaces with exposed skin in
extreme cold conditions.
• Keep the machine clear of all ice and snow.
• Allow sufficient time for the hydraulic oil to warm up
before operating.
• Park the machine in an area where it cannot freeze to
the ground.
Manual Regeneration
WARNING
The engine exhaust will be very hot. Make sure
the machine is not in a highly combustible area.
Failure to follow this warning could cause a fire or
explosion, resulting in death or serious injury.
A manual regeneration is required when the regeneration
icon is flashing yellow. See “Home Screen Function Icons
and Buttons” on page 3-27.
