PARKING LEVER

WARNING

q

When parking the machine, always set the parking lever in the LOCK position.

q

If the parking lever is operated, the brake is applied, even when the machine is traveling.
The machine will suddenly stop, so this is dangerous. For this reason, do not operate the parking
lever when the machine is moving, except in emergencies.

This lever (7) is the control lever for the parking brake.

REMARK

If the parking lever is not at the LOCK position when the engine
is started, the limit switch is actuated and the engine will not
start.
