• Use an appropriate cutting paste and apply it
into the hole before threading operations begin.
• For standard right hand threads set the
selector switch to forward rotation.
• Position the machine onto the work-piece
with the magnet energised and the safety
chain attached.
• Ensure that the machine is positioned so that
the tap 'lines up' with the hole and enters the
hole accurately.
• Switch the motor 'ON' and gently lower the
cutting head until the tap just begins to enter
the hole and starts to cut the thread.
• Allow the tap to determine the feed rate. A light
touch on the feed handle is all that is required
once the tap has begun cutting the thread.
• When the hole has been threaded switch the
machines motor 'OFF'.
• Set the selector switch to reverse rotation.
• Switch the motor 'ON' and allow the tap to
withdraw from the hole.
WARNING: General engineering practice
over many years has determined the ideal
'tapping size hole' required for each size of
tap. Consult an engineering reference book
or chart to ensure that the tap you wish to
use is compatible with the holes drilled in the
work-piece.
• Once the tap exits the hole switch the
motor 'OFF'.

MAINTENANCE

(6.1)
WARNING: Any maintenance must be carried out
with the machine switched off and disconnected
TAPS
from the mains/battery power supply.
Check that all safety features and guards are
9/16" - 15/16"
operating correctly on a regular basis. Only
use this machine if all guards/safety features
9/16"
(15mm or less) are fully operational.
All motor bearings in this machine are lubricated
N/A
for life. No further lubrication is required.
N/A
Use a clean, slightly damp cloth to clean the plastic
parts of the machine. Do not use solvents or similar
products which could damage the plastic parts.
WARNING: Do not attempt to clean by
inserting pointed objects through openings
in the machines casings etc. The machine's
air vents should be cleaned using compressed
dry air.
Excessive sparking may indicate the presence
of dirt in the motor or worn out carbon
brushes.
(6.2)
If this is suspected, have the machine serviced
and the brushes replaced by a qualified
technician.

ADJUSTING THE GIBS

(Dovetail Slides)
WARNING: Only attempt this procedure with
the machine disconnected from the mains
power supply.
Note: All of these machines have adjustable Gibs
(dovetail slides). All are adjusted in the same way,
the only difference between them being the
number of adjustment screws provided.
WARNING: Before every use, lubricate and
adjust the Gibs to ensure that the machines slide
and the cutting head move as outlined below.
When operating the feed handles, the cutting
head and slide should exhibit no 'free play',
yet no binding anywhere through its range
