Setting the laser (Fig.19/20):
Slacken the screws (Z) to adjust the laser. Retighten
the screws after you have made the adjustment.
Important! Never look directly into the laser beam!

8.9 Working instructions

Working speeds
Factors influencing the drilling sped: type of material.
drilled hole size. type of bit. required quality of cut.
Remember that the smaller the bit is the larger is the
required speed. When drilling soft materials. higher
speed is required than that for the hard materials.
Ensure that you drill at the proper speed. Drill speed
is dependent on the diameter of the drill bit and the
material in question.
The table below acts as a guide for selecting the
proper speed for various materials.
The drill speeds specifi ed are merely suggested
values.

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 work-
piece 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.

Countersinking and center-drilling
With this drill you can also perform countersinking
and center-drilling jobs. Please observe that coun-
tersinking should be performed at the lowest speed,
while a high speed is required for centerdrilling.
Metal Drilling
Metal pieces need to be clamped safely. some of
our vices are recommended. Never hold the piece
just with hands. The bit cutting edges may catch
the piece and cause a serious injury to you. The bit
will get broken when a metal object strikes against
the column. The piece to be drilled should be firmly
clamped. Any tilting. twisting and shifting will result
in a rough drilled hole and the risk of breaking the
bit will increase as well. If the metal object is flat.
underlay it with a piece of wood to prevent spinning.
If the shape is irregular and its area cannot lie on the
bench entirely. it should be fixed.
Wood Drilling
It is possible to use the metal working bits for wood
working as well. however. wood drilling bits should
be preferred. Do not use twist drills. those rotate so
fast that they will lift the drilled piece from the bench
and will spin it around. To drill the material through.
the bench has to be aligned for the bit to get in the
centre hole. When the bit starts cutting wood. the
advance should add gradually to prevent the mate-
rial from shattering. Put a piece of waste wood under
the worked material as a pad. It will help to reduce
the shattering qualities and protect the drill bit tip.
Advancement
Apply sufficient force on the advancement hand le-
ver to press it down. interrupt the advancement now
and then to keep the chips short or to direct the saw-
dust from the hole being drilled. Too fast advance-
ment could result in the motor stopping. belt slipping.
damaging the piece being drilled or breaking the bit.
Too slow advancement could heat the drilling bit and
the piece being drilled could get burnt.
m Woodworking
Please note that sawdust must be properly evacu-
ated when working with wood, as it can be a health
hazard. Ensure that you wear a suitable dust mask
when performing work that generates dust.
