MACHINE OPERATION
4-5SY95C Excavator OMM
Cleaning the Cab Interior
Never allow passengers to ride inside or on the
machine. Never bring objects into the cab that
could restrict your movement or vision in any
manner that could result in injury.
Remove all debris from inside the cab to avoid
interference with machine operation.
Check that the escape tool and fire extinguisher are
present. See “Fire Extinguisher” on page 3-34 and
“Escape Tool” on page 3-34.
Prestart Checks and
Adjustments
Complete the following checks and adjustments before
starting the engine each day:
• Check the maintenance log to verify that all required
maintenance checks have been performed before
operating the machine.
• Check fluid levels. See “Fluid Level Checks” on
page 4-5.
• Check the machine for loose hardware, fluid leaks,
and any other signs of damage.
• Inspect the engine compartment for combustible
debris that may come in contact with hot engine
components. Clear all debris from the engine and
engine compartment.
• Check for a loose or damaged engine fan belt and
air conditioner compressor belt.
• Check the undercarriage (track, sprockets, rollers,
and guards) for damage, wear, loose fasteners, and
roller oil leaks.
• Check the bucket or optional equipment for damage.
Lubricate work equipment as necessary. See
“Lubrication” on page 5-41.
• Check the air filter. See “Check and Replace the Air
Filters” on page 5-21.
• Clean the mirrors and check them for damage.
Adjust the mirrors so the area behind the machine is
visible from the operator seat. See “Mirror
Adjustment” on page 4-12.
• Check the seat belt and buckle for damage or wear.
See “Seat Belt” on page 4-12.
• Check the monitor in the cab for proper operation
and maintenance information. (See “Daily
Maintenance Information Screen” on page 3-4 and
“Maintenance Information Screen” on page 3-5.)
Fluid Level Checks
NOTE: Complete the following procedures in this section
before starting the engine.
Check Engine Coolant Level
• Engine coolant is toxic. Avoid inhaling or
ingesting engine coolant. If eyes or skin are
contaminated by engine coolant, wash the
affected area with plenty of water and seek
medical treatment immediately.
• Engine coolant may be under pressure when the
engine is hot. Contact with hot engine coolant
could result in death or serious injury. Allow the
engine to cool before removing the radiator cap.
Failure to follow these warnings could result in
death or serious injury.
1. Prepare the machine for maintenance. See
“Maintenance Safety” on page 2-5.

Figure 4-2
If the overflow tank is empty, there may be an
engine coolant leak. Inspect for engine coolant
leaks and repair if found. If a leak is not found,
check the engine coolant level in the radiator.
Failure to follow this notice could damage the
machine or cause it to operate improperly.
Contact a SANY dealer for additional information.
2. Open the engine hood. See “Unlocking/Opening the
Engine Hood” on page 5-14. Check if the engine
coolant level in the overflow tank (2) is between the
FULL and LOW marks.
