8.
Close the pulley cover.
9.
Run the drill press to check belts for proper tension.
Table adjustments (Fig. 17)
1.
Raise or lower the table by loosening the column lock (1) and turning the handle (2) to desired
position. Retighten the column lock before drilling.
2.
To rotate the table around the column, loosen the column lock (1) and rotate the table to desired
position. Tighten the column lock.
3.
To rotate the table only, loosen the table lock (3) and turn the table to desired position. Tighten
the table lock.
4.
To tilt the table from 0
°
to 45
°
right or left, remove the pin (4) and nut (5). If the pin is sticking,
rotate the nut (5) clockwise until the pin slips out. Loosen the table locking bolt (6), tilt the table
to desired angle and tighten the bolt (6). When returning table to 0
°
, replace the pin (4) and
tighten the bolt (6). The tilt scale is located on the table bracket (7).
Drilling depth (Fig. 18)
1.
To stop the drill at a desired depth for repetitive hole drilling, loosen the depth scale lock (1)
located on the hub (2).
2.
Turn the hub (2) until the pointer is aligned with desired depth.
3.
Tighten the depth scale lock (1). The chuck will stop after traveling downward to the distance
selected on the depth scale.
Spindle return spring (Fig. 19)
The spindle is equipped with an auto-return mechanism. The main components are a spring and a
notched chrome housing. The spring is properly adjusted at the factory and should not be readjusted
unless absolutely necessary. If it needs to be adjusted, proceed as follows:
1.
Unplug the drill press.
2.
Loosen the two housing nuts (1) approximately ¼”.
Do not remove nuts from the threaded
shaft.
3.
Firmly hold the spring housing (2) and pull it out so it clears the raised notch (3). Turn it until
the next notch (4) is engaged with the boss (to increase tension, turn it counterclockwise and to
decrease tension, turn it clockwise). Tighten the two chromed housing nuts. IMPORTANT: Do
not overtighten the nuts. If overtightened, the movement of the spindle handle will be sluggish.
OPERATION
Switch
1.
To turn on the drill press, press the green switch ”I”.
2.
To turn off the drill press, press the red switch ”O”.
NOTE: Use scrap material to get the feel of the machine before drilling the actual workpiece.
Drilling speeds
Important drilling speed factors are: type of material, hole size, type of drill bit and desired cut qual-
ity. Remember that the smaller the drill bit, the greater the required speed. When drilling soft mate-
rials, the speed required is greater than that required for hard materials.
Metal working
A metal workpiece should be clamped down securely. Never hold it with your bare hands; the cut-
ting edges of the drill bit may seize the work, causing serious injury. The drill bit will break if the
metal piece hits the column. Clamp the workpiece firmly; any tilting, twisting or shifting results not
only in a rough hole, but increases the potential of drill bit breakage. If the metal piece is flat, place
