column, clamp them to the table. Failure to do this could
result in personal injury.
Note: for small pieces (A) that cannot be clamped to the
table, use a drill press vise (Optional accessory).
The vice (B) must be clamp or bolt (C) to the table to
avoid injury from spinning work and vise or tool breakage.
drilling a hole.
Make a dent in the workpiece where you want the hole,
using a center punch or a sharp nail. Before turning the
switch on, bring the drill down to the workpiece lining it
up with the hole location.
Turn the switch on and pull down on the feed handles with
onIy enough effort to allow the drill to cut.
FEEDING TOO SLOWLY might cause the drill bit to burn.
FEEDING TOO RAPIDLY might stop the motor, cause the
bett or drill to slip, tear the workpiece loose, or break the
drill bit.
When drilling metal, it may be necessary to lubricate the
tip of the drill with motor oil to prevent burning the drill
bit.
wArning:
For your own safety, turn the switch off and remove plug
from power source outlet before any operation of mainte-
nance on our drill press.
Keep your appliance clean.
Be careful some household cleaning products and solvents
such as benzine, trichloroethene, chloride, ammonium,
etc., can damage plastic parts.
To avoid motor darnage, blow out or vacuurn frequently
this motor to keep drill press dust from interfering with
normal motor ventilation.
power cord.
To avoid shock or fire hazard, if the power cord is worm or
cut, or damaged in any way, have it replace immediately.
lubrication.
All of the ball bearings are packed with grease at the fac-
tory. No further lubrication is required.
Periodically lubricate the splines -grooves -in the spindle
and the rack.
To lubricate the splines, bring do~ the quill and ject the
grease into the spindle from the top of the pulley. Bring
the quill up and down a few times. To lubricate the rack,
bring down the quill and apply grease to the outer surface
of the quill. Bring the quill up and down a few times.
m electrical connection
The installed electric motor is completely wired ready tor
operation.
The customer's connection to the power supply system,
and any extension cables that may be used, must conform
with local regulations.
defective electrical connection cables
Electrical connection cables offen suffer insulation dar-
nage.
Possible causes are:
• Punch points when connection cables are run through
window or door gaps.
• Kinks resulting from incorrect attachment or laying of
the connection cable.

maintenance
• Cuts resulting from running over the connecting ca-
ble.
• Insulation darnage resulting from forcefully pulling out
of the wall socket.
• Cracks through aging of insulation.
such defective electrical connection cables must not be used
as the insulation darnage makes them extremely hazardous.
Check electrical connection cables regularly for darnage.
Make sure the cable is disconnected from the mains when
checking.
Electrical connection cables must comply with the regula-
tions applicable in your country .

single-pHAse motor

• The mains voltage must coincide with the voltage speci-
fied on the motor.s rating plate.
• Dimension cables up to a length of 25 m must have a
cross-section of 1.5 mmª. and beyond 25 m at least
2.5 mmª.
• The connection to the mains must be protected with a
16 A slowacting fuse.
important remark:
The motor is automatical/y switched off in the event of an
overload. The motor can be switched on again after a cool-
ing down period that can vary.

tHree-pHAse motor

• The mains voltage must be between 380 and 420 V
/ 50 Hz.
• The connection to the mains and the connection cable
must have five leads (3 P + N + PE).
• Extension cables must have a cross-section of at least
1.5 mm .
