MACHINE OPERATION
SY155U Excavator OMM
Starting the Engine
WARNING
• 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. Make sure all daily maintenance checks have been
completed. See daily maintenance on page 5-12.
2. Turn the battery disconnect switch to ON. See
“Battery Disconnect Switch” on page 3-15.
3. When in the operator seat, buckle the seat belt. See
“Seat Belt” on page 4-12.
4. Check that the emergency stop switch is in the run
position. See “Emergency Stop Switch” on
page 3-15.

locked (closed) position (2). If the hydraulic lockout

NOTICE!
Before starting the engine, make sure 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.
7. Set the throttle control dial (3) to MIN.
8. Turn the key switch (4) to the ON position and check
the monitor. If all readings are normal and no fault
codes are present, the display will return to the
default screen within 2 seconds.
9. Sound the horn to warn personnel that the machine
is being started.
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 15 seconds. 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.
