In Case Of Emergency; Maintenance; Troubleshooting - Surtek TB512B Manual De Usuario

WARNING: Switch off the machine and
wait until the machine has come to a complete
standstill before changing the speed. Adjust the
speed to the material to be drilled and the drill-
ing diameter.
• For drilling in wood, choose a high speed.
• For drilling in metal and plastics, choose a
lower speed as the drilling diameter increases.
OPERATION
• Use waste material to practise your skills and
to learn operating the machine first.
• When drilling through, adjust the table to
make sure that the drill is aligned with the
opening in the centre of the table. If required,
mark the position on the front side of pillar and
table in case the table should be set in the same
position at a later time.
• Securely tighten the work piece. Toppling,
turning or sliding not only results in a rough
drilling hole, it also in creases the risk of the drill
breaking off.
• Use a piece of waste wood as a backup to re-
duce the risk of the work piece splintering and
to protect the drill tip.
• Place flat work pieces on a wooden under-
ground and clamp securely to the table to pre-
vent them from turning. Support work pieces
that are irregular of shape and cannot be put
flat onto the table.
• Use the lift handles to bring the drill lift down-
wards. Slowly feed the drill into the work piece.
• Drill slowly when the drill is about to break
through the work piece to prevent splintering.

WARNING: for your own safety, always turn
off the switch when the bench drill is not in use
(remove the key and keep it in a safe place, in
the event of a power failure, or transformer ex-
plosion, turn off the switch) lock the switch and
remove the key. This will prevent it from start-
ing unexpectedly when power returns.

MAINTENANCE

The tool does not require special maintenance,
just regularly clean the vents.
WARNING: To avoid electric shock or fire
hazard, if the power cord is broken or worn in
any way, replace it immediately.
LUBRICATION
Turn the drilling to the maximum drilling depth
once every 3 months and grease them gener-
ously with oil.

TROUBLESHOOTING

NOISES WHILE OPERATING

Shaft without greasing. Lubricate the shaft.
Loose shaft pulley. Check the pressure of the
pulley retaining nut, tighten if necessary.
