As with all machines, there is a certain amount of hazard in ol ed with the use of this drill press. Use the
machine with the respect and caution demanded where safety precautions are concerned. When normal safety
precautions are o erlooked or ignored, personal injury to the operator can result.
Read, understand and follow the safety and operating instructions found in this manual. Know the limitations
and hazards associated with an 1150A or 1150HD Drill Press.
Electrical grounding. Make certain that the machine frame is electrically grounded and that a grounding lead is
included in the incoming electrical ser ice. In cases where a cord and plug are used, make certain that the
grounding lug connects to a suitable ground. Follow the grounding procedure indicated by the National Electric
Code.
Eye Safety. Wear an appro ed safety face shield, goggles or glasses to protect eyes. (NOTE: Common
eyeglasses are not safety glasses.)
Personal Protection. Before operating the machine, remo e tie, rings, watch and other jewelry and roll up
slee es abo e the elbow. Remo e all loose outer clothing and confine long hair. Protecti e type footwear should
be worn. Where the noise exceeds the le el of exposure allowed in Section 1910.95 of the OSHA regulations,
use hearing protecti e de ices. Do not wear glo es.
Work Area. Keep the floor around the machine clean and free of tools, tooling, stock scrap and other foreign
material, and oil, grease or coolant to minimize the danger of tripping or slipping. Be sure the table is free of
chips, tools and e erything else not required for the task to be performed. Powermatic recommends the use of
anti-skid floor strips on the floor area where the operator normally stands and that each machine's work area be
marked off. Make certain the work area is well lighted and entilated. Pro ide for adequate work space around
the machine.
Guards. Keep all machine guards in place at all times when the machine is in use. Do not operate the machine
with the guard off.
Operator Position. Maintain a balanced stance and keep your body under control at all times. Do not o er-
reach.
Careless Acts: Gi e the work you are doing your undi ided attention. Looking around, carrying on a con ersa-
tion, and "horseplay" are careless acts that can result in serious injury.
aintain Tools in Top Condition. Keep tools sharp and clean for safe and best performance. Dull tools can
increase the feed force required and can result in burning the stock or seizing up, causing the work to be pulled
free from its holding de ice. Dull or improperly sharpened drills will not produce a straight hole.
Use the Proper Speed and Feed. Tables are pro ided on pages 17-20 as a guide in selecting the correct speed
and feed rate for a ariety of materials. For materials not shown, consult the material supplier for correct speed
and feed rate. Adjust speed on ariable speed models only with the power on. On step cone models, make sure
power is off and the spindle has come to a complete stop before opening the access door to change speeds.
Never Drill Freehand. Always block or clamp the work piece. A drill bit or tap can seize up causing the work
piece, jig, or fixture to rotate with the spindle and can cause serious injury.
Remove Key Chucks: When a key chuck is used, remo e it immediately after using it to lock or unlock a tool in
the chuck. If it is not remo ed, starting the spindle can cause it to be thrown off the chuck and could result in
serious injury.
Hand Safety: Keep hands away from the spindle when the machine is under power. Ne er clear chips when the
spindle is under power and ne er use the hands to clear chips; use a brush or chip rake. Chips are razor sharp
and can cause serious injury. Do Not Change Tools with the Spindle Rotating Under Power.
SAFETY RULES
!

Spindle Rotation: Be sure the rotation of the spindle is correct for the tool being used.
achine Adjustments: Make all machine adjustments with power off except speed on a ariable speed model.
achine Capacity: Do not attempt to use the machine beyond its stated capacity or for operations requiring
more than the rated horsepower of the motor. This type use will reduce the producti e life of the machine and
could cause the breakage of parts which could result in personal injury.
Avoid Accidental Starting: Make certain the motor switch is in the "off" position before connecting power to the
machine.
Job Completion: If the operator lea es the machine area for any reason, the drill press should be turned off and
the spindle come to a complete stop before he departs. In addition, if the operation is complete, he should clean
the machine and work area. Ne er clean the machine with power on and ne er clean chips with the hands; use
a brush or chip rake.
Disconnect achine: Before performing any ser ice or maintenance and when changing tools.
Replacement Parts: Use only Powermatic or factory authorized replacement parts and accessories; otherwise,
the drill press warranty and guarantee will be null and oid.
isuse: Do not use the 1150A Drill Press for other than its intended use. If used for other purposes, Powermatic
disclaims any real or implied warranty and holds itself harmless for any injury that may result from the use. Do
not equip an 1150A Drill Press with a motor larger than 1 horsepower nor with a motor with a speed greater than
4800 rpm unless specifically authorized to do so in writing by Powermatic.
Drugs, alcohol, medication. Do not operate this machine while under the influence of drugs, acohol, or any
medication.
Health Hazards. Some dust created by power sanding, sawing, grinding, drilling and other construction
acti ities contains chemicals known to cause cancer, birth defects or other reproducti e harm. Some
examples of these chemicals are:
* Lead from lead-based paint.
* Crystalline silica from bricks and cement and other masonry products.
* Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures aries, depending on how often you do this type of work. To reduce your
exposure to these chemicals, work in a well- entilated area, and work with appro ed safety equipment, such
as those dust masks that are specifically designed to filter out microscopic particles.
Familiarize yourself with the following safety notices used in this manual:
CAUTION: (This means that if precautions are not heeded, it may result in minor or moderate injury
and/or possible machine damage)

INSTALLATION, ADJUSTMENTS & MAINTENANCE
RECEIVING
Remo e drill press from shipping container and check for damage. Report any damage to the carrier and to your
distributor immediately. Attach accessories shipped with drill press, then clean protecti e coating from table,
column, base and spindle with a good commercial sol ent. Read instruction manual thoroughly for assembly
alignment, maintenance and safety instructions.
INSTALLATION
Mount machine on a solid foundation and lag to the floor through holes pro ided in base of drill press. The head
and table of the machine ha e been lowered on the column for con enience in packaging. If your drill press is
not equipped with an optional head raising assembly, you can raise the head by proceeding as follows:
1. Place a block of wood on top of table and under spindle nose. Raise table until spindle nose contacts the
block.
2. Loosen head locking handles, bumping them lightly to make certain they release.
3. Turn handle counter - clockwise (toward the operator). Head will mo e upward 6".
4. Lock head again with locking handles, raise table to a position just under spindle nose and repeat steps
2 through 4.
5. If the abo e procedure is too slow, use a minimum of three men to mo e head to its proper height; two
to lift head and one to perform the loosening and locking of the handles.
6. After head is at proper height, secure tightly, then slide the safety collar up and lock it in place under the
head. This will pre ent the head from falling if loosened for swing drilling operations.
WARNING: The drill head will fall if the locking handles are loosened and the safety collar is not
secured beneath it. Always lock the safety collar after head has been positioned.
7. Visually align spindle with table and base.
MULTIPLE SPINDLE MODELS
In the case of multiple spindle models, the legs are not attached to the table, they are packed separately. To
assemble the legs to multiple spindle models, carefully support machine on forklift tines or other temporary
supports and bolt legs securely into position. The tables of multiple spindle models are at times shipped in more
than one piece. In joining table hal es, use alignment pins pro ided before securing bolts. These pins guarantee
alignment of table surfaces. It is imperati e that multiple spindle tables be carefully le eled. Use a precision le el
and le el using the jackscrews pro ided in the legs. Lag machine to floor through holes pro ided in legs.
MOTOR INSTALLATION
Step Pulley Models (1150A):
If your machine was ordered less motor, or if the motor is being replaced, the following instructions will
make installation easier.
a. Place motor pulley on motor shaft and insert key.
b. Raise drill press table as shown in Fig. 1. Place motor upright on table and install motor to motor
mount, using (4) 5/16-18 hex nuts. Align motor and spindle pulley and tighten motor pulley set
screws.
c. Loosen lock handle (Fig. 2) and place belt o er pulleys and into lowest speed groo es. Push motor
base clamp to rear for light belt tension and turn lock screw clockwise to lock. Too much tension will
cause excessi e ibration, shaft breakage, bearing noise and wear.

Variable Speed Models (1150HD):
Powermatic prefers to ship all ariable speed drill presses with motors installed. Howe er, if the machine
was ordered less motor, or a motor is being replaced, the following instructions apply.
a. Remo e ariable speed control hub (Fig. 3), from the shaft. Then remo e guard retaining screws and
lift guard from machine.
b. Raise drill press table and lock in position (Fig. 1). Place motor on table in upright position and
attach motor to motor mount, using (4) 5/16-18 hex nuts.
c. Place ariable speed motor pulley on motor shaft (spring up); open pulley by placing ariable
speed belt between hal es and pulling outward on belt. Insert key in keyway, then tighten screws
in the bottom side of the pulley flange.
d. Before replacing guard - temporarily replace ariable speed control hub (Fig. 4). Turn machine on.
The belt should be in a horizontal plane. If belt is cocked at an angle, shut off the motor, loosen
motor pulley and mo e on shaft until belt is le el. Secure setscrew. (See section on changing speeds
for setting speed range.)
e. Remo e handle - replace guard, then control hub. Machine is now ready for operation.
NOTE: The abo e operations are easier to perform with head raised to its maximum height (flush
with top of column) since it is easier to remo e the belt guard with this position.
CHANGING SPEEDS
Speed changes on step pulley models are to be made with the machine not running - loosen motor base clamp
(Fig. 2) and pull handle toward operator. Belt is now free to mo e to any of the 5 speeds a ailable. When speed
choice is made, mo e handle to rear for proper tension and lock the motor base.
Speed changes on ariable speed models are to be made ONLY WHILE MACHINE IS RUNNING. Damage to
ariable dri e mechanism will result if speed is adjusted while machine is not running.
If spindle speed does not appear to match the dial speed on ariable speed unit - check speed with a tachometer
and adjust by unlocking the setscrews in the upper shea e half and turning the top nut on the spline dri e (see
Fig. 4) clockwise to decrease speed and counterclockwise to increase speed.
To set speeds, adjust cam to minimum RPM, adjust by means of nut on the spline dri er to flush belt with outside
diameter of spindle shea e. Mo e motor back until belt has minimum of play. Pull out on one side of the belt. If
there is a minimum of slack, the motor and belt system are properly adjusted in this position. The upper shea e
on the spline dri er has two setscrews which must be unlocked for the shea e to be mo ed. After adjustment
lock the setscrews bring the lock nut down against the hub of the upper shea e and bend a tab of the lockwasher
into the nut to lock its position.
INSTALLING CHUCK
1. Wipe off the No. 33 spindle taper and tapered socket in chuck body (Fig. 5) with a clean cloth. Make
sure no foreign particles are left on these surfaces which could pre ent proper seating of the two parts.
2. Apply a light film of oil on the spindle taper and place chuck on end of spindle (Fig. 5). Screw chuck
collar on to the threads at end of spindle. Hold spindle pulley with one hand to keep spindle from
rotating and tighten the chuck collar with drill chuck key.
3. When remo al of the chuck is required - disconnect power source. Hold top spindle pulley with one
hand and using chuck key handle, loosen chuck collar by turning counter-clockwise (Fig. 5). Continued
rotation of the collar will force the chuck off tapered spindle. NEVER attempt to dri e or wedge chuck
off as damage could result to chuck, spindle nose and spindle bearings.
QUILL ADJUSTMENT
Lateral play or bellmouthing can de elop between the quill and head casting bands due to wear. To compensate
for wear between the quill and head, proceed as follows:
a. Be sure quill lock handle (Fig. 6) is loose.
b. Squeeze slotted head casting together slightly by tightening bolt (A). Apply just enough pressure to com-
pensate for wear but do not restrict free motion down or return.

QUILL RETURN SPRING ADJUSTMENT
Spring tension for return of the spindle, after hole drilling, has been pre-set at the factory. No further adjustment
should be attempted unless absolutely necessary. Adjustment will probably be required if a multiple spindle
drilling or tapping head is used. If adjustment is necessary, loosen lock screw (A) (Fig. 7) while holding quill
spring housing (B). DO NOT allow the housing to turn in your hand or spring will unwind.
Turn entire housing assembly clockwise the number of turns necessary to cause the quill to return to its up
position. (NOTE: The flat of the spring housing pilot is lined up with the spring loading hole on the body of the
spring housing.) Reset lockscrew (A), and make sure point of screw mates to flat on the housing journal.
REPLACING SPINDLES ON QUILL ASSEMBLY
To change the quill assembly for any reason, proceed as follows:
1. Hold quill return spring housing (B) in left hand (see Fig. 7) and loosen lockscrew (A). Let spring unwind
slowly, by allowing housing to turn in hand.
2. Loosen setscrew (C) (Fig. 6) and remo e nut (D) on bottom of depth stop rod. Unscrew and remo e
depth stop.
3. Lower quill assembly to the position where the turret pinion shaft can be remo ed (E). Entire quill
assembly will then slide out of head.
To change spindles, follow the abo e steps, then (Fig. 8):
1. Loosen setscrew in collar (A). To reach this screw, insert a 5/32" Allen wrench through hole (B) in top of
quill.
2. With a hard rubber mallet or block of wood, tap spline end of spindle. The spindle, with bearing (C), will
come out of the quill.
3. Use an arbor press to remo e bearing (C).
4. To replace spindle, re erse abo e procedure.
5. When replacing collar (A), remo e all end play from spindle.
6. When replacing quill in head casting, rotate spindle, if necessary, to engage spline in pulley dri er.
7. If necessary, remo e lock ring (F) and co er plate (G) (Fig. 7) from spring housing and make certain
tongue on return spring (H) is properly inserted in slotted end of pinion shaft. Replace co er and adjust
spring tension as instructed under heading "QUILL RETURN SPRING ADJUSTMENT."
LUBRICATION
All ball bearings in your Powermatic drill press are sealed for life, requiring no lubrication. Points requiring
lubrication are:
1. Internal spline dri e assembly. Keep this area well lubricated with a good grade non-hardening grease,
such as Fiske Company "Lubriplate." Insert grease in the hole at the top of spindle pulley spline dri er.
Lube twice yearly.
2. A light film of oil applied to the quill and column will reduce wear, pre ent rust and assure ease of
operation.
3. Quill return spring should recei e oil (SAE 20) once yearly. Remo e co er plate and apply oil with squirt
can or small brush.
4. IMPORTANT: The hub area of ariable speed pulleys should be coated with a DOW Corning GN Paste
or equi alent.
5. Apply Lubriplate to quill pinion e ery 90 days.
6. Occasional dressing of belt with spray can type belt dressing or parafin wax will promote longer belt life
and quieter operation.
NOTE: Use extreme care when performing this operation and keep hands clear of pinch points. When
using parafin bar, do this only by turning the shea es by hand. DO NOT apply with motor running.
INVERTER DRIVE SYSTEM (1150HD only)
The 1150HD Drill Press utilizes the latest technology in A.C. in erter dri es to pro ide infinitely ariable spindle
speeds. The in erter controls the speed of the motor by arying the frequency of the oltage supplied to the
motor. The in erter pro ides an acceleration ramp that eliminates the shock of normal across-the-line starting.
Also a braking feature eliminates long coasting periods when the drill press is turned off.

SPINDLE ASSEMBLY

16
The 1 HP Baldor motor is wound with "In erter Spike Resistant" magnet wire to gi e extended motor life when
used with in erter dri es. The motor is also specially balanced to reduce noise and minimize ibration.
The A.C. in erter does not require any programming; it is pre-programmed from the factory. The buttons on the
face of the in erter should NEVER be pushed at any time. Use ONLY the controls on the front of the head
assembly.
POWER ONNE TION - ELE TRONI VARIABLE SPEED
The 1150HD Drill Press will operate on single or three phrase, 230V or 460V, depending on the in erter, without
any adjustments or programming. For single phase power, connect hot leads to L1 and L2. For three phrase
power, connect hot leads to L1, L2 and L3 as shown in the wiring diagram on page 39. Remember to always
connect the ground lead.
Before connecting to the power source make sure the ON/OFF switch is in the OFF position, and turn the speed
dial counterclockwise. If the switch is in the ON position when the power is connected, the in erter will trip out.
If this happens, disconnect power, turn switch OFF, wait thiry seconds and then reconnect power.
NOTE: If there is a power outage while operating the 1150HD Drill Press, turn the switch to the OFF position,
disconnect power source, wait thiry seconds then reconnect power source and resume normal operation.
FOOT SWIT H OPERATION (Optional - Model 1150HD only )
The optional foot switch is used only for re ersing the spindle in tapping operations.
Before using the foot switch, place the control switch in the FWD position.
When performing a tapping operation and the tap needs to be re ersed or retracted out of a hole, press the
foot switch and hold it down. The spindle will ramp down and immediately re erse direction. Once the tap has
completely exited or retracted from the hole, release the foot switch and the spindle will ramp down and
immediately return to forward rotation.

DRILL PRESS OPERATIONS
Familiarize yourself with all operating controls before
attempting use of this machine.
CONTROLS (see Figure 10)
1. The spindle (A) in this machine is either a No. 2
Morse Taper or a No. 33 taper type equipped with a
chuck. The key type chuck is 1/2" capacity, held to
the spindle by the taper and a threaded lock collar.
2. A depth stop rod (B) is pro ided to control hole
depth and to pre ent drilling through material into table
surfaces.
3. A quill lock (C) is located on the left side of the
head and is used to hold quill at any position.
4. The turret handle (D) is used to lower the spindle
and quill a total depth of 6".
5. Safety collars (E) are pro ided to pre ent head
and/or table from falling when locks are released. Be
sure collars are in place and securely locked; one
under the head and one under the tilting table. No
safety collar is required for the production table as it
is rack and pinion controlled.
6. Starting switch (F) is mounted on the front of
drill press head within easy reach of the operator.
7. A speed selection chart (G) is located on the
front of the head. This chart is to pro ide assistance
in determining proper drill speed.
8. The model 1150HD is pro ided with an AC-In-
erter (H) which is pre-programmed from the factory
and requires no changing or adjustment.
OPERATING TIPS
1. Determine drill size, inspect for sharpness, in-
sert and lock securely in chuck or Morse taper.
2. Arrange at this point to protect table surface from
drill breakthrough. A piece of scrap material under
the workpiece will pre ent marring table surface and
eliminate splintering at breakthrough point. Lock table
securely to pre ent mo ement.
3. Pre ent the work from being torn from operator's
hand by always securing the workpiece, jig, fixture,
or holding de ice to table by clamping or blocking on
the table. DO NOT use the column as a stop. Clamp
all light workpieces, jigs, fixtures, or holding de ices
to the table to pre ent them from being picked up as
the quill returns.
4. Select the proper RPM for the tool being used,
the material being machined, the operations to be
performed, and other conditions as indicated. (See
Tables I, II, and III on pages 17-20 for recommenda-
tions.) If drill press is the step pulley type, raise door
and set dri e belt in proper ration position. If the ma-
chine is a ariable speed model, turn machine on and
turn control cam to proper speed. NEVER attempt
speed adjustment of ariable speed machines un-
less machine is running. Turn machine off.
5. On tilting table models, be sure to block the part
or holding fixture from sliding off the table when it is
used tilted at an angle. In addition, be sure the table
is clamped.
6. Set depth stop for desired hole depth. Fine ad-
justment is made by turning the fine adjustment col-
lar. Use upper collar to lock stop setting position.
7. If coolant is being used, start flow.
8. Turn machine on and begin drilling operation.
As the breakthrough point is reached, always slow
feed rate down slightly to assist in elimination of burr-
ing underside of workpiece and to help pre ent a sud-
den break through which can cause the drill to grab
and pull the workpiece free of its clamping de ice.
8. Perform all operations with a minimum exten-
sion of the quill. Adjust table or head position rather
than using excessi e quill tra el.
