Depth Gauge - General International DP2002 Mode D'emploi

DEPTH GAUGE

1. To stop the drill's downward travel at a consistent specific depth,
particularly for repeat drilling, loosen the depth scale lock (ff, fig 7)
located on the depth scale ring (gg, fig 7).
2. Rotate this ring until the pointer (hh, fig 7) is aligned to the desired depth
on the scale.
3. Tighten the depth scale lock. The quill will stop travelling downward at
the set distance.
OPERATING INSTRUCTIONS
WARNING! Before using this machine, the operator should carefully
read over this operation manual and acquaint himself with the
construction, controls and drive system of the drill press.
SELECT THE SPEED
1. The material you are drilling into and the size of hole you are planning to
make should determine the speed at which you set the drill press. As a
rule of thumb, small drill bits require more speed than large drill bits and
soft materials require more speed than hard ones.
Speed range
2000 to 3100 rpm 3/8"
1400 to 2000 rpm 5/8"
1000 to 1400 rpm 7/8"
800 to 1000 rpm 1-1/4"
530 to 800 rpm 1-5/8"
* These speeds are only general guides and vary further according to the
particular material you are working with (the kind of wood, for instance),
the type of drill bit or cutter you are using, any lubricants you may use and
the quality of the cut desired.
2. Select the speed by moving the belt to the appropriate pulleys.
DRILL BIT
1. Insert the drill bit into the chuck (K, fig 3) far enough to obtain maximum
grip from the chuck jaws. Make sure the drill bit is centered in the chuck.
2. Insert the chuck key (L, fig 2) and turn it clockwise to tighten (and
counter-clockwise to loosen) the drill bit. It is good practice to turn the
chuck key in each of the three holes of the chuck when tightening it.
3. Before the final tightening with the chuck key, be sure the drill bit is
centered in the chuck jaws.
4. Tighten the chuck sufficiently to prevent the bit slipping in the jaws
during drilling. As a test, turn the drill press on and immediately off to
check if the drill bit wobbles.
LASER
1. Place a work piece on the table.
2. Turn the laser switch on (I).
DANGER! Do not stare directly at the laser beam. Eye damage may
occur if you deliberately stare into the beam.
3. Lower the drill bit (not turning) to touch the work piece. The two laser
lines should cross where the drill meets the work piece.
4. If the laser needs to be adjusted:
● Using a hex wrench, turn the laser adjustment hex screws (3)
counterclockwise.
