• Before setting the lock lever to FREE (F) position, make sure that all levers and pedals are set to
NEUTRAL position. If any of them is out of NEUTRAL position, the work equipment or machine may

ment, swing, travel, and attachment are locked automatically

ated while the lock lever is in FREE position (F).

check that each control lever and the attachment switch are in
neutral, and then release the lock lever again.
