Check all hoses and lines for leaks. Contact a SANY
dealer to replace damaged or leaking hoses or lines
immediately. Any hydraulic pump lines or connectors
connected to the engine compartment must be replaced
if damaged.
Make sure there is sufficient clearance between all
hydraulic lines and hoses and the high-temperature
engine components. Make sure there is no friction
between them. Make sure no hydraulic lines and hoses
come in direct, unprotected contact with each other.
Track Assembly
Check the Track Tension
NOTICE!
Remove gravel or mud buildup between the
sprocket and the track before checking track
tension.
1. Use the bucket as a support to lift the track on one
side.
WARNING
After elevating, make sure the elevated machine is
adequately supported. Failure to support the
machine may cause serious injury or death.
2. Support the elevated side of the machine with
suitable jack stands or wood blocking.
3. Rotate the track one full revolution.
4. Prepare the machine for service. See “Maintenance
Safety” on page 2-5.

5. Use a straightedge to measure the track sag (1)
between the tread of the roller and the rail surface of
the track.
6. Normal track sag is 0.59 in.–0.98 in.

(15 mm–25 mm). If the track sag is outside of this
range, the track tension must be adjusted.
Adjust the Track Tension
WARNING
• The track tension grease fitting is under extreme
pressure. Grease can exit the grease valve and
cause serious injury.
• Wear safety goggles, gloves, and other personal
protective equipment (PPE) to prevent serious
injury.
• Do not stand directly in front of the track tension
grease fitting valve when loosening the valve.
Failure to follow these warnings could result in
death or serious injury.
WARNING
• If the track remains too tight after opening the
track tension grease valve, or if the track remains
too loose after adding grease to the track tension
grease fitting, never attempt to remove the track
or remove the track adjuster.
• Pressurized grease inside the track adjuster may
cause serious injury if any component is
disassembled before pressure is released. If this
occurs, contact a SANY dealer for further
instructions.
Failure to follow these precautions could result in
injury.
