To switch the machine ON, press the switch cover (fig. 3) in, slide in direction of arrow and
lift up, this will expose the ON/OFF buttons. Push the ON button, (green button ‘I’). DO
NOT close the cover as this will switch the machine OFF again.
NOTE : in case of emergency, close the switch cover quickly, the cover will latch down
and the motor will be switched OFF. To switch OFF normally, press the OFF button, (red
button ‘O’), always close cover to prevent accidental starting. always allow the motor to
reach full speed before attempting to start machining, check that there is no adverse
vibration or noises etc. If any are apparent, switch the machine OFF and disconnect from
the main supply by turning OFF the power and removing the plug from the socket. Rectify
any faults before attempting to turn the machine back ON again.
Once any problems are rectified and the machine is running smoothly, the machine is
now ready for use.
Operating Instructions
(Figures in brackets refer to Parts list)
NOTE: these instructions are not a definitive tutorial. they are to be used for guide
purposes only and are not intended to teach you all there is to know about milling and
drilling.
Always keep the work area clean and tidy. especially in the close proximity of the machine.
Plan your work carefully before starting.
•
Secure work piece onto the worktable, using the appropriate method, e.g, ‘T’ bolts
and clamps not supplied) or vice etc.
•
Insert the cutter to be used into the chuck (not supplied) or directly into the spindle
etc and ensuring it is tightly secured. Only use good quality cutters with the correct
form and sharpness etc.
•
Ensure the chuck guard is in place and securely fixed.
•
For added accuracy, if for instance you are only using the cross feed when cutting,
ensure all other axis are locked, (vertical and horizontal).
•
Select the correct cutting speed for the size of cutter and material being machined.

Chuck Guard
NEVER operate the machine without first ensuring that the chuck guard is in place and
is functioning correctly, when guard is opened, the machine stops automatically.
To position the chuck guard where it gives maximum protection from flying swarf etc,
loosen the two knurled thumb screws, shown in Fig. 6, raise or lower the guard to required
position.
Maintenance
(Figures in brackets refer to Parts list)
The amount of maintenance depends on the amount of use the machine gets, however
it is important to carry out routine maintenance to prevent premature wear and shortening
the life of the machine.
1. Inspect and clean all non painted surfaces, lubricate using a light machine oil, Do
Not over lubricate, oil can be applied to the worktable and column etc, using a soft
oil soaked cloth.
2. Inspect and clean all moving parts, Lubricate using machine oil, check for smooth
operation.
3. Inspect the machine for signs of wear or damage, any faults should be rectified
before continuing.
4. Check all bolts etc are tight, i.e. the bolts (134) securing the column (132) to the base
(141) etc.
5. With use, play may develop in the cross and longitudinal slides, this can be adjusted
out as follows.
Before making any adjustments, clean all friction surfaces, it is necessary to move the
table and cross slide to both extremes to carry out the cleaning process correctly.
When finished cleaning, re-lubricate using a light machine oil.
6. Return both the table and cross slide to their central positions.
7. Adjust Gib strip screws, (160) (see Fig. 7). Using suitable screwdriver, slowly turn the gib
