DRILL MOUNTING

6. OPERATION
6.1.
WARNING! Ensure the drill is unplugged from the mains power supply before commencing.
Install drill bit
6.1.1.
Insert drill bit into chuck jaws to 1" (25mm) deep (avoid inserting small bits too far) and centre bit in chuck before tightening jaws with
chuck key.
6.2.
ADJUSTING THE TABLE
6.2.1.
To adjust table up, down or round the column, loosen clamp bolt (fig.1.A). Move table to required position and tighten clamp bolt
(fig.1.A).
6.2.2.
To adjust table tilt, loosen the work table bolt (fig.1.B), adjust to the desired angle using the angle scale, then re-tighten.
6.3.
ADJUSTING THE SPEED
6.3.1.
Open the pulley cover and loosen the belt tension lock screw (fig.4.A).
6.3.2.
Choose the speed for drilling operation (see drill speed chart) and move the belt 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 screw (fig.4.A) loosened the motor plate spring will automatically give the correct belt tension (belt give of
approx. 13mm under finger pressure). Tighten lock screw and close pulley cover.
6.5.
POSITIONING THE WORK PIECE
6.5.1.
Use a piece of wood to rest the work piece on. The drill bit may break through the work piece and damage the table otherwise.
6.5.2.
The wood should rest on the table so that one end of it is against the left side of the column. When the drill bit breaks through the
work piece, it will contact the wood and cause it to spin. Resting the wood against the column will prevent this.
6.5.3.
For small work pieces that cannot be clamped to the table, use a drill vice (not included). Vice must be clamped or bolted to table.
6.6.
SETTING DRILL DEPTH
6.6.1.
Use the scale at the front of the drill head.
6.6.2.
Loosen lock nuts on threaded rod and adjust so that at desired drill depth, nuts contact head lug and prevent further drill movement.
Tighten lock nuts.
6.6.3.
When ready to drill, simply pull the feed handle. The drill feed will stop at the set depth.
6.7.
GUARD
6.7.1.
Always adjust guard length, by loosening wing nut at each side (fig.5.A), to give maximum protection before starting to drill.
