SAFETY RULES
As with all machines, there is a certain amount of hazard involved 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 overlooked 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 service. 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 approved safety face shield, goggles or glasses to protect eyes. (NOTE: Common
eyeglasses are not safety glasses.)
Personal Protection. Before operating the machine, remove tie, rings, watch and other jewelry and roll up
sleeves above the elbow. Remove all loose outer clothing and confine long hair. Protective type footwear should
be worn. Where the noise exceeds the level of exposure allowed in Section 1910.95 of the OSHA regulations,
use hearing protective devices. Do not wear gloves.
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 everything 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 ventilated. Provide 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 overreach.
Careless Acts: Give the work you are doing your undivided attention. Looking around, carrying on a conversation, and "horseplay" are careless acts that can result in serious injury.
Maintain 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 device. Dull or improperly sharpened drills will not produce a straight hole.
Use the Proper Speed and Feed. Tables are provided on pages 17-20 as a guide in selecting the correct speed
and feed rate for a variety of materials. For materials not shown, consult the material supplier for correct speed
and feed rate. Adjust speed on variable 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, remove it immediately after using it to lock or unlock a tool in
the chuck. If it is not removed, 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. Never clear chips when the
spindle is under power and never 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.
4
Spindle Rotation: Be sure the rotation of the spindle is correct for the tool being used.
Machine Adjustments: Make all machine adjustments with power off except speed on a variable speed model.
Machine 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 productive 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 leaves 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. Never clean the machine with power on and never clean chips with the hands; use
a brush or chip rake.
Disconnect Machine: Before performing any service 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 void.
Misuse: 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
activities contains chemicals known to cause cancer, birth defects or other reproductive 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 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 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)
!
WARNING: (This means that if precautions are not heeded, it could result in serious injury or
possibly even death).

INSTALLATION, ADJUSTMENTS & MAINTENANCE
RECEIVING
Remove 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 protective coating from table,
column, base and spindle with a good commercial solvent. 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 provided in base of drill press. The head
and table of the machine have been lowered on the column for convenience 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 move 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 above procedure is too slow, use a minimum of three men to move 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 prevent 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 halves, use alignment pins provided before securing bolts. These pins guarantee
alignment of table surfaces. It is imperative that multiple spindle tables be carefully leveled. Use a precision level
and level using the jackscrews provided in the legs. Lag machine to floor through holes provided 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 over pulleys and into lowest speed grooves. Push motor
base clamp to rear for light belt tension and turn lock screw clockwise to lock. Too much tension will
cause excessive vibration, shaft breakage, bearing noise and wear.

Variable Speed Models (1150HD):
Powermatic prefers to ship all variable speed drill presses with motors installed. However, if the machine
was ordered less motor, or a motor is being replaced, the following instructions apply.
a. Remove variable speed control hub (Fig. 3), from the shaft. Then remove 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 variable speed motor pulley on motor shaft (spring up); open pulley by placing variable
speed belt between halves 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 variable 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 move on shaft until belt is level. Secure setscrew. (See section on changing speeds
for setting speed range.)
e. Remove handle - replace guard, then control hub. Machine is now ready for operation.
NOTE: The above operations are easier to perform with head raised to its maximum height (flush
with top of column) since it is easier to remove 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 move to any of the 5 speeds available. When speed
choice is made, move handle to rear for proper tension and lock the motor base.
Speed changes on variable speed models are to be made ONLY WHILE MACHINE IS RUNNING. Damage to
variable drive mechanism will result if speed is adjusted while machine is not running.
If spindle speed does not appear to match the dial speed on variable speed unit - check speed with a tachometer
and adjust by unlocking the setscrews in the upper sheave half and turning the top nut on the spline drive (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 driver to flush belt with outside
diameter of spindle sheave. Move 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 sheave
on the spline driver has two setscrews which must be unlocked for the sheave to be moved. After adjustment
lock the setscrews bring the lock nut down against the hub of the upper sheave 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 prevent 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 removal 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 drive or wedge chuck
off as damage could result to chuck, spindle nose and spindle bearings.
QUILL ADJUSTMENT
Lateral play or bellmouthing can develop 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 compensate 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 remove nut (D) on bottom of depth stop rod. Unscrew and remove
depth stop.
3. Lower quill assembly to the position where the turret pinion shaft can be removed (E). Entire quill
assembly will then slide out of head.
To change spindles, follow the above 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 remove bearing (C).
4. To replace spindle, reverse above procedure.
5. When replacing collar (A), remove all end play from spindle.
6. When replacing quill in head casting, rotate spindle, if necessary, to engage spline in pulley driver.
7. If necessary, remove lock ring (F) and cover 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 cover 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 drive 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 driver.
Lube twice yearly.
2. A light film of oil applied to the quill and column will reduce wear, prevent rust and assure ease of
operation.
3. Quill return spring should receive oil (SAE 20) once yearly. Remove cover plate and apply oil with squirt
can or small brush.
4. IMPORTANT: The hub area of variable speed pulleys should be coated with a DOW Corning GN Paste
or equivalent.
5. Apply Lubriplate to quill pinion every 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 sheaves by hand. DO NOT apply with motor running.
INVERTER DRIVE SYSTEM (1150HD only)
The 1150HD Drill Press utilizes the latest technology in A.C. inverter drives to provide infinitely variable spindle
speeds. The inverter controls the speed of the motor by varying the frequency of the voltage supplied to the
motor. The inverter provides 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.
