Hydraulic Oil/Ambient Temperature
Data
NOTICE!
To prevent damage to the hydraulic system,
perform the following warm-up procedure in
ambient temperatures below 32°F (0°C).
• Start the engine and run it at idle speed for 7 to 10
minutes. Increase the engine speed to 1200 rpm
and perform only no-load traveling for a
minimum of 30 minutes or until the hydraulic oil
temperature is at least 68°F (20°C).
• Proceed with normal operation only after
completing the warm-up as described above, or
adjust the warm-up period according to the
ambient temperature. During normal operation,
take care to operate the controls slowly and
observe the traveling system for any signs of
trouble. Operation with oil temperature of 68°F
(20°C) or below may damage the hydraulic
system.
Diesel Exhaust Fluid (DEF)
All diesel exhaust fluid (DEF) must meet ISO 22241-1.
Engine Coolant
Any engine coolant brand meeting Cummins® Engine
Standard Classification (CES) 14603 may be used.
Cummins recommends the use of Fleetguard® ES
Compleat™ coolant.
Lubricants
NOTICE!
Use only lubricants recommended in this manual.
Using other lubricants can damage the machine
and could cause improper machine operation.
Contact a SANY dealer for assistance if the
machine will be operated in subzero temperatures
where the use of an auxiliary heating device is
required.
Grease
Always use clean extreme pressure (EP) grease when
greasing this machine. Avoid using low-viscosity
greases. SANY recommends an EP 2 or equivalent
grease designed for:
• Heavy-duty bearings and general industrial
lubrication.
• Heavy-duty plain and rolling-element bearings
operating under severe conditions, including shock
loading in wet environments.

NOTE: Select the proper hydraulic oil based on local operating climate and conditions:
• Use ISO VG 46 anti-wear hydraulic oil in generally temperate climates.
• Use ISO VG 32 low-temperature anti-wear hydraulic oil (pour point is -43.6°F [-42°C]) in generally arctic
areas where ambient temperatures can reach -22°F (-30°C) during operation.
