BELT TENSION ROD.,, maintains constant tension on the
belt, TO RELEASE belt tension for changing speeds,
push the GRIP of the rod up.
To APPLY belt tension, PUSH the MOTOR to the REAR
while pulling DOWN on the GRIP of the rod. Belt should
only be tight enough so that it does not slip. If belt slips
while drilling, readjust belt tensioning rod
FEED HANDLES ... are for moving the quill up or down.
One or two may be removed if necessary whenever the
workpiece is of such unusual shape that it interferes with
the handles.
Although there is a rubber cushion between the FEED
STOP COLLAR and the head, NEVER let go of the feed
handles when you have finished drilling a hole.
Hold on to the handle while allowing the quill to return to
the UP position.
DRILLING SPEED ...Canbechanged by placing the belt
in any of the STEPS (grooves) in the pulleys. See Spindle
Speed chart on right side of Head.
To determine the approximate drilling speed, refer to the
table on the RIGHT side of the drill press head, For
example to drill a 5/8 inch hole in wood, the belt is placed
in the FOURTH step from the top. The speed will then be
2300 RPM (revoJutions per minute).
QUILL LOCK ... Holds the quill at any desired point
within its travel.
To lock the quill requires only moderate pressure on the
lock handle.
FEED STOP NUT limits the downward movement of the
quill at any desired point within its travel, and prever_ts the
pointer from moving upward,
