Accumulator

This machine is equipped with an accumulator charged with high-pressure nitrogen gas. Do not disassemble the

accumulator.

Never expose the accumulator to temperatures above 140ºF (60ºC) or open flames.
Never weld on the accumulator.
Never strike the accumulator.
If the accumulator needs maintenance, contact a SANY dealer.

Electrical System

Always clean the electrical system using industry-approved electrical cleaners.
Never use caustic soaps, high-pressure water, or steam cleaners to clean the electrical system. These could damage
the system or cause intermittent system failures.

Battery Safety

When working with batteries, always work in a well-ventilated area. Batteries present a hazard, especially when
they have been in use for a long period of time. The following are some basic precautions for working around
batteries:
• Always wear personal protective equipment (PPE).
• Battery gases are extremely explosive. Smoking, sparks, or open flames could cause an explosion. When
opening a battery compartment, always allow ample time for battery gases to escape.
• If the battery is corroded, clean it with a mixture of warm water and baking soda.
• If battery acid gets on skin or in eyes, flush the area immediately with fresh water and seek medical
attention.
Check the battery's condition only with proper test equipment.

Disconnect the Battery

When disconnecting the batteries, always disconnect the negative (-) cable first. Then disconnect the positive (+)
cable.
NOTE: Disconnecting the cables between the batteries may not completely interrupt the electrical system.
