WARN I N G
Ensure battery disconnect switch is in OFF position before performing this task. Failure to follow this warn-
ing may result in injury to personnel or damage to equipment.
To prevent injury to personnel, wear protective eye covering and gloves.

system pressure has been relieved. Tighten all connections before applying pressure. Escaping hydraulic fluid
under pressure can penetrate the skin, causing injury to personnel.
At operating temperature, hydraulic oil is hot. Allow hydraulic oil to cool before disconnecting any hydraulic
lines. Failure to follow this warning may result in injury to personnel.
