Idling The Engine; Cold Weather Engine Starting - SANY SY60C Operation And Maintenance Manual

NOTICE!
In order to prevent starter damage, do not operate
the starter motor for more than 15 seconds. If the
engine does not start. allow the starter motor to
cool for at least 2 minutes. If the engine does not
start the second time, turn the key switch to OFF
and wait a minimum of 2 minutes before trying to
start the engine again.
If the engine fails to start after five attempts,
contact a SANY dealer.
9. Turn the key switch to START. When the engine
starts, release the key. It will return to ON.

Idling the Engine

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.
Allow the engine to idle until the engine coolant
temperature reaches 140°F (60°C) before beginning
operation.

Cold Weather Engine Starting

• Before starting the engine or leaving the operator
seat, make sure the hydraulic lockout control
lever is in the locked (closed) position. If the
hydraulic system is not locked, unintentional
machine operation may occur.
• Confirm that the surrounding area is clear of
personnel and obstructions, and sound the horn
before starting the engine.
• Always start the engine from the operator seat.
Never start the engine by shorting the starter
solenoid or starter relay.
• Never use ether starting fluid to start the engine.
Ether is highly flammable and can cause a fire or
an explosion.
• Exhaust gas contains carbon monoxide. Carbon
monoxide is an invisible and odorless gas, and is
toxic. Provide adequate ventilation when starting
the engine in a confined space.
Failure to follow these warnings could result in
death or serious injury.
1. Check the fluid levels before starting the engine.
Drain the water and sediment from the fuel water
separator once a week. See "Check and Drain the
Fuel Water Separator" on page 4-7.
2. Turn the battery disconnect switch to ON. See
"Battery Disconnect Switch" on page 3-21.

WARNING
3. When in the operator seat, buckle the seat belt. See
"Seat Belt" on page 4-11.
The machine should not move when the hydraulic
lockout control lever is in the closed position. If it
does, contact a SANY dealer. Failure to correct
this could result in death or serious injury.
4. Move the hydraulic lockout control lever to the locked
(closed) position. If it is in the unlocked (open)
position, the engine will not start.
5. Make sure the control levers/pedals are in the neutral
position, move freely, and return to the neutral
position when released.
Before starting the engine, make sure that the
throttle control dial is at MIN (low idle). Starting
with the throttle control dial at MAX (high idle) will
accelerate the engine and could damage it.
6. Set the throttle control dial to MIN (low idle).
7. Turn the key switch to the HEAT position and
release. The key switch returns to OFF. The preheat
cycle begins if the coolant temperature is below a
preset temperature. When the preheat cycle begins,
a preheat icon is illuminated on the home screen.
When the preheat cycle is complete, the preheat icon
will turn off.
8. Turn the key switch to ON and check the monitor. If
all readings are normal and no fault codes are
present, the display will return to the default page
within 2 seconds.
9. Sound the horn to warn personnel that the machine
is being started.
In order to prevent starter damage, do not operate
the starter motor for more than 15 seconds. If the
engine does not start. allow the starter motor to
cool for at least 2 minutes. If the engine does not
start the second time, turn the key switch to OFF
and wait a minimum of 2 minutes before trying to
start the engine again.
If the engine fails to start after five attempts,
contact a SANY dealer.
10. Turn the key switch to START. When the engine
starts, release the key. It will return to ON.
NOTE: If the engine fails to start after preheating, wait at
least 5 seconds before repeating the process.
