ADJUSTING SPINDLE RETURN SPRING

For the purpose of automatically returning the

spindle upward after the hole has been

drilled, a spindle return spring is provided in

the spring housing ✷✌ Fig. 21. This spring

has been properly adjusted at the factory and

should not be disturbed unless absolutely

necessary. To adjust the return spring,

proceed as follows:

1. Disconnect the drill press from the power

supply.

2. Loosen the nut ✸✌ slightly. Do not remove

nut ✸✌ from shaft ✹✌.

3. While firmly holding spring housing ✺✌

Fig. 22 pull out housing and rotate it until the

boss ✻✌ is engaged with the next notch on

the housing. Turn the housing anticlockwise

to increase and clockwise to decrease spring

tension. Then tighten the nut to hold the

housing in place.

IMPORTANT:

Nut ✼✌ Fig. 24 should not contact spring

housing when tight.

DRILLING HOLES TO DEPTH

Where holes are to be drilled to exactly the

same depth, a depth stop is provided in the

pinion shaft housing and is used as follows:

1. Loosen lock handle ✾✌ Fig. 23 and rotate

housing ✽✌ until the pointer ✿✌ lines up with

the depth you wish to drill on the scale ❀✌.

Then tighten lock handle ✾✌.

2. All holes will then be drilled to the exact

depth, as indicated on the scale.
