SPINDLE DEPTH STOP
Located on the spindle feed shaft is a
depth stop collar, carrying a
graduated scale (A, in Fig.13). The
collar can rotate around the shaft
and may be locked in place by the
locking screw B.
The graduations represent the hole
depth in mm.
TO SET A DRILLING DEPTH:
1. With the drill bit installed and tightened securely, lower it with the power off,
so that the bit lightly touches the workpiece.
2. Hold in that position whist slackening the locking knob (B) and rotating the
scale (A) ANTICLOCKWISE until it stops with the zero mark opposite the
pointer (C).
3. Tighten the knob and allow the mechanism to return to its starting position.
4. Note the reading on the scale. This will be the measured distance of the
drill bit from the workpiece.
5. Decide on the depth of hole required and add this (in mm), to the value on
the scale. Re-tighten the knob.
• e.g. If the drill was 27 mm from the workpiece and you require a 10
mm deep hole, slacken the knob and turn the scale to read 37 mm.
The drill is now set to drill holes to your desired depth. Providing your workpiece
is level and flat, you may drill a series of holes, each to the same depth, quickly
and accurately.
CHANGING THE 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 knob to relieve tension on
the drive belts.
3. Refer to the chart inside the pulley
cover or the table on page15 and
position the belts on the pulleys
according to the drilling speed
required.
