Swing Stops (Fig. 12A)
Two Swing Stops are provided to assist in drilling pocket holes in the same
location on multiple work pieces of the same dimension. When the Swing
Stop is not used, it will pivot out of the way to allow the work piece to slide
underneath and rest against the fence. To change the location of the Swing
Stop simply loosen the knob, move to the new location and tighten the Knob
to lock the Swing Stop in position.
Changing the Drill Bit
(Fig. 12B & 12C)
IMPORTANT! Before changing the Drill Bit, make certain your machine
is DISCONNECTED from the AIR SUPPLY. Cycle the machine via the
Handle to remove air from the system. Without an air supply you can be
certain the Drill Bit will not accidentally engage while you are performing
this adjustment. While the air supply line is disconnected from the Air Motor
pressurized air with lubricating oil will be vented inside the cabinet if the
handle is accidentally moved to the operating position unless the machine
is DISCONNECTED from the AIR SUPPLY.
1. Disconnect the machine from the air supply.
2. Remove the Black Acrylic Top to gain access to the inside of
the machine.
