7.0 Routine Adjustments/Maintenance

7.1 Adjusting the Vertical Stroke

The depth of vertical stroke is controlled with a stop screw knob on top of the drill.  Turning the knob
clockwise lowers the drill spindle while turning it counter-clockwise raises the drill spindle.  This
adjustment should be set so that the drill bit just cuts through the bottom sheet of a lift.  Do not set
this adjustment too low or the drill will “burn” into the cutting block at the bottom of its stroke.

NOTE

:  Whenever changing drill bits or using slitting, slotting, or cornering attachments, be sure to

back off the spindle stop screw to prevent ruining stock and damaging drill bits and cutting blocks.

7.2 Removing the Cutting Block

Disconnect the power cord and simply reach under the table and push the block up, grasping it when
it clears the table.

7.3 Removing Drills From the Chuck

  Always handle drills with care to avoid severe lacerations; even dull drills

are sharp enough to cause lacerations.

Disconnect the power cord.  Rotate the drill drift cover (spring clip) on the end of the chuck to uncover
the drift hole. The cover prevents drill chips from flying out of the drift hole while drilling small
diameter holes.

  

Insert the drill drift, flat side down, into the hole and lift upward.  The upward

movement forces the drill down and releases it from the chuck.

NOTE

: After heavy drilling, the drills may become so firmly seated in the chuck that it is necessary to

tap on the drift to get the drill to release.  To prevent this, always use a sharp drill and lubricate often.

7.4 Service Checklist

  Always disconnect the power cord when cleaning, servicing or lubricating.

7.4.1 Daily

Sharpen the hollow drill often and reset the spindle adjusting screw if needed.

Lubricate the hollow drill frequently with the Drill-Ease provided.

For better hollow drill life, remove the drill when not in use, remove any drill chips from inside the drill
shaft and soak in light oil.

7.4.2 Weekly

Disconnect the power and clean guide bar shaft.  Lubricate with standard 30-weight oil.

Clean side guide shaft and lubricate with light oil.

Lubricate all spindle lever linkage pins with light oil.
