Weld, Drill, Cut, or Grind on the Machine

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.
• Disconnect the battery and all electrical control modules prior to welding. Failure to do this
could damage the machine and personal property or cause it to operate
• improperly.
• After turning off the key switch, wait 1 minute before disconnecting the battery. Disconnect
the negative battery cable from the negative (-) post of the battery prior to welding.
• 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 it to
operate improperly.

Inspection and Maintenance for Severe Operating Conditions

If the machine will be operating under adverse conditions:
• Check and clean any electrical components to prevent 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.
