What is what

IMPORTANT!
Direction should NEVER be changed while
machine is switched to ON position (this is
why there is a lock on the FWD/REV switch).
If direction needs to be changed, turn ma-
chine back to OFF position, wait for 1 minute,
change direction and then switch back on.
Once direction setting has been changed,
remove key from FWD/REV switch before
switching back on.
Changing of direction while machine is run-
ning will result in motor failure.
