6. Keep guards in place and in working order when the machine is in use. If removed for maintenance purposes,
use extreme caution and replace the guards immediately.
7. Remove adjusting keys and wrenches. Form habit of checking to see that keys and adjusting wrenches are
removed from tool before turning it on.
8. Keep work area clean. Cluttered areas and benches invite accidents.
9. Do not use in dangerous environment. Don't use power tools in damp or wet locations, or expose them to
rain. Keep work area well lighted.
10. Keep children away. All visitors should be kept safe distance from work area.
11. Make workshop kid proof with padlocks, master switches, or by removing starter keys.
12. Don't force tool. It will do the job better and safer at the rate for which it was designed.
13. Use the right tool. Don’t force a tool or attachment to do a job for which it was not designed. The right tool will
do the job better and safer at the rate for which it was designed.
14. Use proper extension cord. Make sure your extension cord is in good condition. When using an extension
cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will
cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows the correct size to use
depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller
the gage number, the heavier the cord.
15. Wear proper apparel. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which
may get caught in moving parts. Nonslip footwear is recommended. Wear protective hair covering to contain
long hair.
16. Always use safety glasses. Also use face or dust mask if cutting operation is dusty. Everyday eyeglasses only
have impact resistant lenses, they are NOT safety glasses.

•
Lead from lead based paint.
Crystalline silica from bricks, cement and other masonry products.
Arsenic and chromium from chemically treated lumber.
Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure to
these chemicals: work in a well-ventilated area and work with approved safety equipment, such as face or
dust masks that are specifically designed to filter out microscopic particles.
31. Make certain the switch is in the OFF position before connecting the machine to the power supply.
32. Make certain the machine is properly grounded.
33. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless
acts that can result in serious injury.
34. The operator should not wear gloves when operating the machine.
35. All doors should be closed, all panels replaced and other safety guards should be in place prior to the
machine being started or operated.
36. Be sure the drill bit is not in contact with the work piece when the motor is started. The motor should be
started and up to full speed before bringing the drill bit into contact with the work piece.

Depth Stop
A drilling depth stop (refer to Figure 3) is provided on
the right side of the drill head. The depth stop
consists of a threaded rod with depth setting jam
nuts. The front side of the threaded rod has a depth
scale. The jam nuts are loosened and moved to the
desired depth on the scale. The upper jam nut is
then tightened against the lower nut.
8. Make sure the spindle taper is clean and free of
burrs, scoring, and galling to assure maximum
gripping.
Drilling Recommendations
Speeds for Drilling
The speed of a drill is usually measured in terms of
the rate at which the outer periphery of the tool
moves in relation to the work being drilled. The
common term for this is Surface Feet per Minute
(SFM). The relationship of SFM is expressed in the
following formulas:
SFM = 0.26× RPM × Drill Diameter (in Inches)
SFM
RPM = 3.8×
Drill Diameter (in Inches)
In general, the higher the speed the shorter the drill
life. Operating at the low end of the speed range for
a particular material will result in longer life. The
most efficient speed for operating a drill depends on
many variables:
Figure 3 – Depth Stop
1. Composition and hardness of material.
2. Depth of the hole.
Operating Precautions
3. Efficiency of the cutting fluid.
4. Type and condition of the drilling machine.
5. Desired quality of the hole.
6. Difficulty of set-up.
The following operating and safety precautions must
be observed in order to avoid harm to the operator
or damage to the drill press.

3. Remove head cover.
Indication of Extreme Speeds and Feeds
A drill that splits up the web is evidence of too much
feed or insufficient tip clearance at the center as a
result of improper grinding. The rapid wearing away
of the extreme outer corners of the cutting edges
indicates that the speed is too high. A drill chipping
or braking out at the cutting edges indicates that
either the feed is too heavy or the drill has been
ground with too much tip clearance.
4. Remove belt. (With speed control setting at the
highest speed, the belt should be loose enough
to remove.)
5. Install the replacement belt. Install the head
cover.
6. Connect electrical power to the drill press.
7. Operate the drill press to verify correct
operation.

Adjustments
Table Adjustment
The table can be raised or lowered to accommodate
the height of the component being drilled (refer to
Figure 4). To raise or lower the table, loosen the
lock handle. Then use the hand crank to move the
table to the desired height. Then retighten the lock
handle.
Figure 4 – Table Adjustment
Head Adjustment
Change the radial position of the
drill head only if the drill press base is secured
to the floor. Swinging the drill head without the
base being secured to the floor will cause the
drill press to become unstable and tip over
resulting in injury and/or damage to the machine.
The radial position of the drill head can be changed
to accommodate the drilling of a hole that may be
offset from the center of the table. Reposition the
drill head by loosening the locking handles and
swinging the drill head to the desired position. Then
retighten the locking handles.
Wiring Diagrams
Refer to Figure 5 for wiring information. The drive
motor is115/230 volt single phase or 220/440 volt
three phase. Notice: When converting machine
voltage, it is necessarry to re-wire the LED display
connection accordingly. Refer to figure 5.

Grounding Instructions
This tool must be grounded
while in use to protect the operator from electric
shock.
Important: In all cases (115 or 230 volts), make
certain the receptacle in question is properly
grounded. If you are not sure, have a registered
electrician check the receptacle.
In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric shock.
This tool is equipped with an electric cord having an
equipment-grounding conductor and a grounding
plug. The plug must be plugged into a matching
outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
Do not modify the plug provided. If it will not fit the
outlet, have the proper outlet installed by a qualified
electrician.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor, with insulation having an outer surface
that is green with or without yellow stripes, is the
equipment-grounding conductor. If repair or
replacement of the electric cord or plug is necessary,
do not connect the equipment-grounding conductor
to a live terminal.
Check with
a
qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to whether
the tool is properly grounded. Use only three wire
extension cords that have three-prong grounding
plugs and three-pole receptacles that accept the
tool’s plug.
Repair or replace a damaged or worn cord
immediately.
Extension Cords
Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one
heavy enough to carry the current your machine will
draw. An undersized cord will cause a drop in the
line voltage resulting in power loss and overheating.
The table following shows the correct size to use
depending on the cord length and name plate
ampere rating. If in doubt, use the next heavier
gauge. Remember, the smaller the gauge number,
the heavier the cord.
