lock lever is not in LOCK position and the control levers or control pedals are touched by mistake, it
may lead to serious personal injury or death.
• Check that the lock lever is securely in LOCK position.
• When pulling up or pushing down the lock lever, be careful not to touch the work equipment control
lever. Check that your clothes do not get caught by the work equipment control lever.
• Before setting the lock lever to FREE position, make sure that all control levers and pedals are set
to NEUTRAL position. If any of them is out of NEUTRAL position, the work equipment or machine
may move suddenly and cause a serious personal injury or death.
The lock lever is a device to lock the work equipment, swing,
travel, and attachment (if equipped) operations.
Be sure to operate the lock lever by the operating portion (g).

als (if equipped) are operated,
