Switch Activation
To reduce the likelihood of accidental start-up, the switch is
equipped with safety buttons 6 that must be depressed
before the trigger 7 can be activated. The safety buttons are
designed to be activated by the right or left thumb pushing in
the left to right direction. When either safety button is
depressed, the trigger is unlocked and it can be pulled to
activate the motor. Once the trigger is activated, release the
safety button so it can automatically engage and lock the
switch upon release of the trigger.
Avoid positioning the palm of your
hand over the safety button. Pressure from the palm of your
hand may unintentionally unlock the safety button or prevent
it from automatically engaging and locking the switch upon
release of the trigger.
NOTE: Switch can accommodate a padlock with a long
shackle of up to 1/4" in diameter (not provided with
compound miter saw) to prevent unauthorized use.
