Cleaning the Machine
Never clean the machine with caustic chemicals or steam
cleaners. Instead, use mild soaps and a pressure washer
to clean the machine. Always protect electrical parts
when cleaning the machine. Never flood or
pressure-wash the inside of the cab. Use only
nonflammable cleaning solvents. Never use flammable
liquids to clean parts or systems.
Weld, Drill, Cut, or Grind on the
Machine
NOTICE!
Disconnect the battery and all electrical control
modules prior to welding. Failure to do this could
result in damage to the machine and personal
property or cause the machine to operate
improperly.
NOTICE!
• Contact a SANY dealer before beginning any
welding repairs. Any welding repairs on the
machine must be performed by personnel who
are qualified and certified to perform repairs that
require welding. Owners are responsible for the
structural integrity of any completed repair.
• After turning off the key switch, wait 1 minute
before disconnecting the battery. Remove the
negative battery cable from the negative (-) post
of the battery.
• The welding ground cable must be connected
within 3.3 ft. (1 m) of the welding area. The
welding cable must be connected directly to the
part being welded. Do not ground through
bearings, hydraulic cylinder pins, or work
equipment pins.
Failure to disconnect the negative battery cable
could damage the machine or cause the machine
to operate improperly.
Daily Inspection and Maintenance
With the engine off, check the following before operation:
• Perform daily service as necessary.
• Inspect the machine for loose or missing fasteners
and components.
• Clean the cab.
• Check all controls for smooth operation and make
sure they return to the neutral position.
• Make sure all safety decals are in place and are
legible.
• Check for fluid leaks.
With the engine running, check the following operations:
• Monitor the control panel for normal machine
operating parameters.

Inspection and Maintenance for
Severe Operating Conditions
If the machine will be operating under adverse
conditions:
• Check and clean electrical components to remove
any accumulated corrosion.
• Check and clean any areas where extreme heat is
present, such as the exhaust system, manifold, and
turbocharger.
For heavy-load operation, add grease to the pins of the
work equipment prior to each operation. Cycle the
operation of all working parts several times before filling
with additional grease.
Mud, Rain, or Snow Conditions
Before operating the machine, inspect each connector for
looseness.
After operating the machine, clean the machine and
inspect for missing or loose fasteners. Add oil and
lubricating grease as needed.
Near Ocean (Salt Air) Environments
Before operating the machine, inspect for any signs of
corrosion. Apply grease where rust is found.
After operating the machine, thoroughly wash away the
salt residue, apply grease where rust is found, and
perform maintenance carefully on the electrical
components to prevent corrosion.
