Ega Master 79632 Manuel D'instructions page 29

Before using the machine, please read these instructions!
Remove the unit from its case along with the accessories and check that all parts are included; the
box should contain:
· Drilling unit
· Accessory pack containing:
- Safety chain & carbine hook
- Allen key SW 2.5 for wear strip adjustment
- Allen key SW 4 for arbor. (This is for fitting cutters)
· Oil bottle with plastic hose
· This operation and maintenance manual
Preparation
1. Insertion of pilot pin
The pilot pin is used to both center the cutter and to eject the slug on completion of the cut. It has
a flat side to allow the coolant to run down to reach the center of the cut where the heat is greatest.
Slide the pin through the hole in the center of the cutter shank.
2. Fitting the cutter
Lay the machine on its side, ensuring the set screws are accessible. Loosen both screws to permit
shank of the cutter to slide home in the arbor with the two flats aligned with the set screws. Tighten
the set screws in turn until the cutter is locked. Do not over-tighten the screws.
If a pilot pin is used, ensure that it slides freely in the cutter.
3. Clean any dirt or swarf from the base of the magnet and the work piece with a gloved hand. Mark
the position of the hole by a center-punch. Place unit in correct position for drilling.
4. Place unit in correct position for drilling with the pilot over the center-punch. The magnet will hold on
all ferrous materials from a minimum of 6 mm (1/4") thickness.
5. Attach safety chain by looping it through the handle of the unit and around the work piece or other
suitable anchor point, take up any slack in the chain and clip the hook through a convenient link in
the free end of the chain.
6. Check the air connection with a suitable supply (6 bar/90PSI, 64 SCFM/1,8 m
7. Connect the free end of the lubrication hose to the adapter of the motor.
Drilling
1. Activate the magnet using the control lever.
2. Check magnet is holding to work piece. Recheck the pilot is still centered on the hole position –
activating the magnet can sometimes cause the unit to move slightly from the center mark,reposition
if necessary.
3. Using the pressurized oil bottle add oil to the work piece. Ensure only the correct cutting oil is used,
it has been formulated to speed cutting and enhance tool life.
4. Start the motor. Motor will not run unless magnet is activated. If for any reason the airflow is
interrupted, the switching system will leave the magnet on. The unit will switch itself to a drill off
position and will need to be switched back to drilling when the supply is re-connected.
5. Advance the cutter to the work piece using light pressure until the cutter has broken the surface,
then increase the pressure until the motor is loaded and maintain even pressure right
through the cut. Too much pressure will not speed the cut, it will reduce the life of the cutter
and may cause damage to the motor. If the turnings become blue add more oil. At the end of
