Speed is low when the trigger switch is
pulled slightly and increases as the
switch is pulled more. To turn the switch
OFF, release the trigger switch to its
original position. However, the switch
trigger can only be pulled in halfway
during reverse and rotates at half the
speed of forward operation.
Pulling the trigger and pushing the
stopper, it keeps the switched-on
condition which is convenient for
continuous running. When switching off,
the stopper can be disconnected by
pulling the trigger again. The switch
stopper is unusable during reverse.
