In order to hold the spindle, insert the Tommy Bar into the hole in the side of the head so

that it locates in the hole in the spindle, see Fig. 5. Hold the spindle still whilst nipping up the

draw bolt. .

Fig.6

Place the drill chuck on to the end of the taper shank with

a sharp upward movement.

The drill is lowered using the levers on the right side of the

machine, however, in order to do so, it is first of all

necessary to disconnect the Dog Clutch, shown in Fig. 6.

Simply pull back on the hub to disconnect.

Now by turning the handles, the drill head may be lowered.

In order to ensure the drill chuck is firmly secured on the

spindle, place a piece of wood on the table then lower

the drill head so that the nose of the drill chuck comes

into contact with it. Pull down sharply one time.

When drilling using a mill/drill machine, it must be

remembered that without care, the drill bit could easily

come into contact with the surface of the table.

Fig.7

Drill head travel must always be restricted therefore

before proceeding to drill, otherwise damage to the

table and/or drill bit could occur.

A limiting device is provided, mounted on the post

slide, shown in Fig. 7.

When through drilling, wind the drill head, with drill bit

installed, down to the maximum depth required, and

hold in place whilst sliding the limit device up to meet

it. Lock the limit device in place using its’ locking lever.

The limit device is also used if you wish to drill to a

predetermined depth.

Bring the drill bit down to touch the workpiece surface

and note the reading on the scale on the post.

Move the workpiece away from the drill bit, using the

longitudinal or cross slide handles, then lower the head once again to the depth

previously noted, plus the depth of hole required. At this point, bring the limit device up to

the head and lock firmly in place . Your drill depth is now set.

The workpiece must ALWAYS be firmly secured. This will normally be with the use of a vice

which is securely clamped to the table. Alternatively, clamps may be used. A suitable

vice, and a ‘T’ nut and clamp set designed specifically for this machine, are available

from your Clarke dealer. Please refer to Accessories on page 22.

The table, carrying the workpiece, is manoeuvred using the longitudinal and cross slide

adjusting handles. Once the workpiece is positioned, any further movement is avoided by

locking both longitudinal and cross slides in place using the locking levers provided - see

parts identification Fig-B, on page 8.

Drill speeds are effected by using either the High or Low ranges together with the variable

speed rotary switch. See notes on cutting speeds on page 13.

WARNING

Never attempt to change ranges until the machine has come to a complete stop
