FittinG the saFety Guard
Drill GuarD instructions
Ensure drill unit is isolated from power supply.
Two screws to support the guard in position,
one either side of the drill.
If necessary press the plastic guard guides into
their locating holes on ether side of the motor
cradle
Fit guard to drill as shown.
Secure guard to drill with screws and washers
supplied. DO NOT overtighten the fixing screws,
these should be loose enough to allow the
guard to rise when required. lower guard to
drilling surface.
when drilling, the guard should always be in
contact with the surface being drilled. As the
drill is lowered, the guard will rise in relation
to the drill.
FittinG the oil Bottle
The cutting oil bottle is held in a sprung bracket
attached to the top of the drill body. Fit the
bracket by removing one of the cap screws from
the top plate and replace the bolt through the
fixing lug on the bottle bracket, tightening the
bolt enough to allow some radial movement of
the bracket. The coolant tube is a push fit into
the self-seal gland at the base of the tap and a
similar fitting on the lower arbor bracket.

FittinG the saFety straP
The supplied safety strap should be used
wherever possible as a safety precaution in the
event of a power failure releasing the magnet;
particularly in situations where the machine is
clamped onto a vertical surface or in an inverted
position.
saFety strap instructions
when the machine has been clamped to the
workpiece in the correct position for drilling,
the strap should be fed through the channel
between the body of the drill and the magnet,
then passed around a substantial part of the
workpiece. The free end should then be passed
through the buckle, pulled tight and locked.
Once the cut is complete, the strap should be
released and the machine supported before the
magnet is disengaged.

Insertion of pilot pin
• The pilot pin is used to both centre the cutter and to
eject the slug on completion of the cut. It has a flat side
to allow coolant to run down to reach the centre of the
cut where the heat is greatest. Slide the pin through the
hole in the centre of the cutter shank

Insert shank of cutter into arbor, push it home and release
the sleeve, Fig.2.
Twist the cutter in the arbor to ensure the flat is engaged
in the locking mechanism, Fig.3.
Turn the sleeve fully anti-clockwise to complete the locking
operation, Fig.4.
To remove the cutter, simply twist the sleeve clockwise
against the spring, the cutter will be ejected.
Mark the position of the hole

• Cutting oil ensures longer cutter life and enables the
slug to be ejected cleanly. A 500 ml bottle is included with
every machine.
• Oil will be automatically delivered to the cutter when
the cut commences
• when cutting on vertical surfaces or upside down, cutting
paste, gel or foam is recommended. It is best applied inside
