FIG. 8
ADJUSTMENTS
7.DEPTH STOP: The depth stop and scale are
found on the left side of the on/off switch. To
adjust, lower the drill chuck until the pointer
shows your desired depth on the scale .
Loosen the lower nut on the threaded shaft
(FIG. 7, A) until it bottoms out on the head
casting (B). Tighten the upper nut against the
lower nut to retain the adjustment.
8. TABLE TILT:
 The drill press table will tilt
0-45 degrees left and right. To tilt, loosen the
nut located under the table (FIG. 8,  A). 
Align
the
  “zero” mark on the table (FIG. 9, B) to the
desired degree marking on the scale.
Tighten the nut under the table
to retain the
adjustment.

9. SPINDLE SPRING TENSION: The spindle
return spring tension may need adjustment if
the spindle returns too rapidly or too slowly.
A. Place a screwdriver in the lower front notch     
    (1) of the spring cap (2). Hold it in place while   
    loosening and removing only the outer nut (3).
B. With the screwdriver still engaged in the notch,  
    loosen the inner nut (4) just until the notch (5)  
    disengages from the boss (6) on the drill press 
    head.
CAUTION: 
DO NOT REMOVE THIS INNER      NUT
 (4), because the spring will forcibly unwind.

ADJUSTMENTS
    B. Loosen the motor lock knob (FIG. 12, A), 
         then move the motor (B) manually toward 
         the feed handle to take tension off of the    
         belt.
    C. Move the drive belt to the desired speed 
         position - refer to speed chart inside of the 
         belt cover.     
10.CHANGING SPINDLE SPEED: The 47747
Bench Drill Press has five spindle speeds.
To change;
    A.  Lift the cover with the handle to reveal the 
         motor and spindle pulleys, and drive belt.   
         FIG. 11. 
FIG. 11
FIG. 12
FIG. 13
     D. Manually move the motor away from the 
         feed handle until the belt is tensioned, then 
         tighten the motor lock knob.
          NOTE: The belt is properly tensioned when 
         the deflection distance is about 3/8” to 1/2”  
         when pushed by hand. FIG. 13.
    E.  When the desired speed is set and the 
         motor is locked in place, close the cover, 
         plug in the machine to resume drilling.
Five Speeds are available:
     740, 1100, 1530, 2100, 3140 RPM A
B
THE MACHINE MUST NOT 
BE PLUGGED IN AND THE POWER SWITCH 
MUST BE IN THE OFF POSITION UNTIL ALL 
ADJUSTMENTS ARE COMPLETE.
C. Carefully turn the spring cap (2) counterclock- 
    wise with the screwdriver, engaging the next   
    notch. FIG. 10.
D. Lower the spindle to the lowest position while 
    holding the spring cap (2) in position.
E. When the spindle moves up and down as 
    easily as you desire, tighten the inner nut
9. SPINDLE SPRING TENSION  -  continued
    (4) with a wrench. If too loose, repeat steps  
    2 through 4 to tighten. If too tight, reverse 
    steps 3 and 4. DO NOT OVERTIGHTEN as 
    this will restrict the spindle movement. F. Replace the 
outer nut (3) and tighten it against 
    the inner nut (4) to prevent the inner nut from 
    reversing. 
						

							OPERATION1. Installing A Drill Bit
See Fig. 1
4
A
.   With the switch “OFF”, open the chuck jaws (1) using the chuck key (2).        
 Turn the chuck key counterclockwise to open the chuck jaws (1).  
B
.     Insert the drill bit (3) into the chuck far enough to obtain maximum               gripping by the jaws, but not far enough to touch the spiral grooves  
       (flutes) of the drill bit when the jaws are tightened. 
C.   
 Make sure that the drill is centered in the chuck.  
D.     Turn the chuck key clockwise to tighten the jaws.
       W ARNING: To avoid injury or accident by the chuck key ejecting forcibly 
       from the chuck when the power is turned ON, always recheck and re-  
       move the chuck key before turning the power ON.
2. Positioning Workpiece
If not using a table fence, to prevent the workpiece or back-up material
from being torn from your hands while drilling, you  MUST position it
against the LEFT
 side of the column. Failure to do this could result in
personal injury. See Fig.15
3. Using Vise
For small workpieces that cannot be clamped to the table, use a drill press
vise. The vise must be clamped or bolted to the table.
W
ARNING: The drill press vise MUST
 be clamped or bolted to the table to
avoid injury from a spinning workpiece, or damaged vise or bit parts. See Fig.16
4. Drilling a Hole
Using a center punch or a sharp nail, make an indentation in the workpiece
where you want to drill. Turn the power switch on and pull down the feed
handles with only enough effort to allow the drill to cut.
FEEDING TOO RAPIDLY might cause the belt or drill to slip, tear the work -
piece loose, or break the drill bit. When drilling metal, it will be necessary to 
lubricate the tip of the drill bit with metal drilling oil to prevent it from  Figure 14
Figure 15
Figure 16
Figure 
17DRILLING T
O A SPECIFIC DEPTH
Drilling a blind hole (not all the way through the workpiece) to a given depth 
can be done two ways:
Workpiece method (Figure 1 6 and 17)A
. Mark the depth (2) of the hole on the side of the workpiece.(1) (Figure 1
6).B
. With the switch “OFF”
, bring the drill bit (2) down until the tip is even with
the mark (Figure 16 ).C.
Hold the feed handle at this position.
D.
Spin the lower nut (3) down to contact the depth stop lug (6) on the head
(Figure 

17).
E
. Spin the upper nut (5) down and tighten against the lower nut
(3)(Figure 
17).F.
The drill bit will now stop after traveling the distance marked on the work- 
    piece.
Depth scale method (Figure 
17)A
.With the switch “OFF”, turn the feed handle until the pointer (7) points to
the desired depth on the depth scale (4) and hold the feed handle in that
position.
B
.Spin the lower nut (3) down to contact the depth stop lug (6).
C.
Spin the upper nut (5) against the lower stop nut and tighten.
D.
The drill bit will stop after traveling the distance selected on the depth
scale.

ARNING: Be sure drill press is turned off and is disconnected from power sours before adjusting speeds.
Use the recommended speed for the drill bit and workpiece.

							15MAINTENANCE
WIRING DIAGRAM
This machine must be grounded. Replacement of the power supply cable sho\
uld only 
 be done by a qualified electrician. See page 5 for additional electrical information.
1. Before each use:
-  Check the power cord and plug for any wear or 
damage.
-  Check for any loose screws or hardware.
-  Check the area to make sure it is clear of any 
misplaced tools, lumber, cleaning supplies, etc. 
that could hamper the safe operation of the drill 
press.
2. To avoid a build-up of wood dust, regularly
clean all parts of the machine using a soft cloth, 
brush or compressed air. A general cleaning 
should be done after every use to avoid future 
problems and ensure the machine is in ready 
condition for the next time it is used.WARNING: If blowing sawdust, wear proper eye 
protection to prevent debris from blowing into 
eyes. 
 Turn the power switch “OFF” and disconnect the plug from the outlet prior 
to adjusting or maintaining the machine. DO NOT attempt to repair or maintain the electrical 
components of the motor. Contact a qualified service technician for this type of maintenance.
3. Keep the table, column and base free of
resin and rust. Clean them regularly with a non-
flammable solvent, then coat with a light film of 
dry lubricant spray, or wax, to keep their surfaces 
clean. Do not use ordinary oil which will collect 
dust and hamper the operation of the machine.
4. All of the ball bearings are lifetime lubricated,
sealed, and do not need any further care. Keep 
the drive belts free of oil and grease. 
5. Check the belt tension after the first 3-5 hrs.
of operation to ensure that the belts have not 
become stretched and loose from their 'breaking 
in' use. See page 12 for instructions.
NOTE: Refer to pages 3 - 6 for more information 
on proper machine usage and user safety.
This tool is intended for use on a circuit that has a 120 volt electrica\
l receptacle. 
The illustration on page 5 shows the type of the 120V, 3-wire electrical plug and electrical receptacle that has a grounding conductor that is required.
