NOTICE
The padlock shaft diameter is important to
the disabling function of the switch. With
any padlock used to lock the switch, test
the switch after installation to ensure that it
is properly disabled.
Children or untrained people can be killed
or seriously injured by this machine. This
risk increases with unsupervised operation.
To help prevent unsupervised operation,
disable and lock the switch before leaving

hidden or secure location.
Disabling & Locking Switch

The ON/OFF switch can be disabled and locked
by inserting a padlock through the ON button,
as shown. Locking the switch in this manner can
prevent unauthorized operation of the machine,
which is especially important if the machine is not
stored inside an access-restricted building.
IMPORTANT: Locking the switch with a padlock
only restricts its function. It is not a substitute
for disconnecting power from the machine when
adjusting or servicing.
