ADJUSTING THE SPEED
NOTE: the belt cover is fitted with a micro-switch to prevent drill operation with the cover open.
6.3.1.
Open the pulley case and loosen the belt tension lock screws (fig.6.A) - one either side of head.
6.3.2.
Choose the speed for drilling operation (see drill speed chart - Section 7) and move the belts to the correct position for that speed, as
shown on the chart inside the pulley cover.
6.4.
BELT TENSION
6.4.1.
With the belt tension lock screws (fig.6.A) loose and using hand pressure on the adjusting handle (fig.5.C), set tension so that belt
deflection is no more than 1/2" (13mm). Tighten lock screws.
6.5.
POSITIONING THE WORKPIECE
6.5.1.
Use a piece of wood to rest the workpiece on. The drill bit may break through the workpiece and damage the table otherwise.
The wood should rest on the table so that one end of it is against the left side of the column, to prevent it spinning when the drill
bit breaks through the workpiece.
6.5.2.
For small workpieces that cannot be clamped to the table, use a drill vice (not included). Vice must be clamped or bolted to table.
6.6.
SETTING THE DRILL DEPTH
