SETTINGS AND ADJUSTMENTS
Before adjustments are made, ensure that the machine is SWITCHED OFF AND UNPLUGGED. Also
make sure all locking handles and securing screws are FULLY TIGHTENED when adjustments are
completed.
TO ADJUST THE TABLE
The table is capable of being raised, lowered, or swiveled about
the column by:
Slackening off the table support locking handle (A), adjusting ac-1.
cordingly, and re-tightening the handle; or,
It may also be tilted by loosening the Set Screw (B), tilting to the2.
required position, (up to 45 degrees in either direction) and re-
tightening the Set Screw.
SETTING THE REQUIRED ANGLE
A Bevel Scale (C), provided on the table mounting, is measured1.
in degrees to assist in setting the required angle. For all normal
operations the table should be set at 0° (see Figure 3).
To ensure the drill is entirely perpendicular to the table, insert a2.
piece of straight round bar in the chuck, place a square on the
table and bring it up to the round bar. Adjust the table tilt if neces-
sary so that the table is correctly aligned.
TO SET DRILLING DEPTH
Located on the left side of the drill head (G) is the Spindle Feed (or depth feed) adjuster assembly,
which allows the depth of the hole to be set. The procedure for setting the drilling depth is as follows (See
Figure 4):
Lower the Chuck (F) until the drill contacts the surface of the1.
workpiece and hold that in position.
Screw down the adjuster nut (B) so that the gap between its un-2.
derside and face (E) is the depth of the hole required.
Screw down nut (C) and lock it against the adjuster nut (B).3.
The drill is now set to drill holes to your predetermined depth from
that particular start point (i.e., providing the surface of your workplace is
at and level, you may drill a series of holes, each to the same depth.
The scale (H) and pointer (D) can be used to drill one off, by lowering the chuck — as explained
above in “To Set Drilling Depth” section — until the drill contacts the work, setting the pointer (D) against
a set point on the scale (H), switching the drill ON and proceeding to drill to the required depth using the
scale (H) as a guide.

CHANGING DRILL (SPINDLE) SPEED
Before changing the speeds, make sure the machine is switched OFF and UNPLUGGED.
Open the pulley cover.1.
Slacken off the Belt Tension Locking Screw to relieve any tension on the drive belt.2.
Consult the chart inside the pulley cover (or3. Figure 5 on page 10) and position the belt on the pul-
leys according to the spindle/drill speed required
When the belts have been correctly positioned, tighten them by levering the motor away from the4.
head until the belt deects by approximately 1/2” at its center when using reasonable thumb pres-
sure. Lock the motor in this position with the Belt Tension Locking Screw.
DRILL SPEED TABLE
The table below shows the belt arrangements for given drill speeds (A full chart is also located on
the inside of the pulley cover). In the diagram, the belts are tted to Step Three of the Spindle Pulley,
producing a drill speed of 1,720 RPM.

OPERATION
1. Insert the drill into the jaws of the chuck approximately 1”, ensuring that the jaws do not touch the
utes of the drill. Before tightening the chuck, ensure that the drill is centered within the jaws.
Refer to Figure 6.
Make sure the table height and position is set so that the2.
drill travel range is sufcient for the material to be drilled.
Make sure the work is securely clamped. That is, held in a3.
drill vice, or bolted to the table. Never hold the material with
your bare hands while drilling. Severe personal injury may
be caused if the material is ung out of the operator’s hand.
IF THE MATERIAL IS IRREGULARLY SHAPED and cannot4.

WHEN DRILLING COMPLETELY THROUGH WOOD, always position a piece of scrap wood be-7.
tween the material and the table to prevent splintering on the underside of the material as the drill
breaks through. The scrap piece of wood must make contact with the left side of the column as
shown in Figure Five. Also, set the depth of the drill so that the drill will not come in contact with
the table - or align the table so that the hole in its center is in line with the drill bit.
Once the instructions above have been followed, lower the Chuck Guard into place and switch the8.

Note: A micro switch is provided inside the Pulley Cover that prevents the machine from operating unless
the Pulley Cover is rmly closed.
Cutting Speeds
Factors which determine the best speed to use in the drill press operation are:
Type of material to be drilleda.
Size of holeb.
Type of drill bitc.
Quality of the hole/cut desired.d.
Generally, the SMALLER THE DRILL BIT the GREATER THE REQUIRED RPM. In soft material, the speed should be
higher than for hard metals. As a guide, the drill speed for a given drill bit size is listed in the chart below.
SPEED RANGE (RPM) 3100 2340 1720 1100 620

GROUNDING/VOLTAGE WARNING
Common household current is 110-120 volts. As long as your tool is rated from 110-120V there will be no complications
using this tool with household receptacles. Plug the press into a 110-120V properly grounded outlet protected by a
15-amp, dual element time delay or circuit breaker.
NEVER try to plug a 110-120V tool into a 220-240V circuit (or vice versa) or serious complications and possible injury
to the operator may occur. The plugs have different shapes to prevent this.
This piece of equipment has a three-prong plug. The third (round) prong is the ground to protect the operator from
electric shock. Cutting off the ground will result in a safety hazard and void the warranty.
IF THE OUTLET YOU ARE PLANNING TO USE IS THE TWO-PRONG TYPE, DO NOT REMOVE OR ALTER THE
GROUNDING PRONG IN ANY MANNER. Use an adapter and always connect the grounding lug to a known ground-
ing source. IT IS RECOMMENDED THAT YOU HAVE A QUALIFIED ELECTRICIAN REPLACE THE TWO-PRONG
OUTLET with a properly grounded three-prong outlet.

EXTENSION CORDS
Your tool has a three-prong plug, therefore you must use a three-prong extension cord. Only use rounded jacket
extension cords listed by the Underwriters Laboratories (UL).
The extension cord must have a minimum wire size depending on the amperage of the tool and the length of the ex-
tension cord. This size is determined by its AWG (American Wire Gauge) rating. The smaller the gauge, the greater
the cable’s capacity. The amount of cords used does not matter: Total length determines the minimum AWG rating.
Every cord must meet the AWG rating. Use the chart below to determine what AWG rating is required for your situa-
tion. Cord length is rated in feet. Harbor Freight Tools can supply UL listed and outdoor rated cords in multiple
AWG ratings if needed.

MAINTENANCE
CLEANING: Regularly clean the work surface with dry brush or clean cloth. Keep machined parts of the press lightly
greased. Always keep the motor and chuck clean. Prevent metal, wood, dust and debris from accumulating in this
area. If jaws do not operate smoothly, have the chuck serviced by a qualied technician.
LUBRICATION: For average use, lubricate twice a year with #20-30 weight household oil. Lubricate more frequently
with increased usage.
POWER CORD: Inspect the power cord periodically and, if damaged, have it repaired by an authorized technician.
REPLACEMENT PARTS: Replace belts at the rst sign of slippage or fraying. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty.
STORAGE: Always remove and store drill bits.
