SPINDLE DEPTH STOP
Located around the spindle feed
shaft is a depth stop collar carrying a
graduated scale (A, Fig.13). The
collar is capable of turning about the
shaft and may be locked in place by
locking screw B. The graduations are
metric (mm).
To set a drilling depth:
With the drill bit installed and
tightened securely, lower it...WITH THE
POWER OFF, so that it lightly contacts the work, and hold in that position with
one hand whist slackening the locking screw (B) and rotating the scale (A)
ANTICLOCKWISE until it stops.
The zero mark should now be opposite the pointer (C).
To check to ensure the table is square to the drill, insert a piece of straight
round bar in the chuck, place a square on the table and bring it up to the
round bar. Adjust the table tilt if necessary so that the table is correctly aligned
Maintaining a light pressure on the drill bit, back off the scale ring until the
value of the desired depth of cut (mm), is opposite the pointer, then tighten
the locknut (B).
The drill is now set to drill holes to your desired depth. i.e. Providing your
workpiece is level and flat, you may drill a series of holes, each to the same
depth, quickly and accurately.
CHANGING DRILL (SPINDLE) SPEED
Before changing the speeds, ensure the machine is switched OFF, and
disconnected from the power supply.
1. Open the pulley cover.
2. Slacken off the belt tension
locking screw, to relieve any
tension on the drive belt.
3. Consult the chart inside the pulley
cover, and position the belt on the
pulley’s according to the spindle
speed required.
4. When the belt has been correctly
positioned, re-tension by levering
the motor away from the head, until the belt deflects by approx. ½” at its
centre when using reasonable thumb pressure. Lock the motor in this
position with the belt tension locking screws.
