SAFETY INSTRUCTIONS
Read, understand and follow the safety and operating instructions found in this manual. Know the limita-
tions and hazards associated with a 1200HD Drill Press. A safety rules decal is installed on the belt guard of
this machine to serve as a reminder of basic safety practice.
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 when operating the drill
press.
Personal Protection. Before operating the machine, remove tie, rings, watch and other jewelry and roll up
sleeves above the elbow. Remove all outer loose clothing and confine long hair . Protective type footwear
should be worn. Hearing protectors should be used where noise exceeds the level of exposure allowed in
Section 1910.95 of the OSHA regulations. 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.
Do Not Overreach. Maintain a balanced stance and keep your body under control at all times.
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. A table is provided in the instruction manual 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.
Spindle Rotation. Be sure the rotation of the spindle is correct for the tool being used.
Machine Adjustments. Make all machine adjustment s with power off except speed on a variable speed
model or feed rate on machine equipped with power feed.
4
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 Accident al St arting. Make certain the motor switch is in the "off" position before connecting power to
the machine.
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 .
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; other-
wise, the drill press warranty and guarantee will be null and void.
Misuse. Do not use the 1200HD 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 a 1200HD Drill Press with a motor larger than 2 horsepower nor with a motor with
a speed greater than 1800 rpm unless specifically authorized to do so in writing by Powermatic.
If you are not thoroughly familiar with the operation of drill presses, obtain advice from your supervisor ,
instructor or other qualified person.
Drugs, alcohol, medication. Do not operate this machine while under the influence of drugs, alcohol, 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.

INSTALLATION, MAINTENANCE AND ADJUSTMENTS
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.
1. Using a crane and sling with blocks to prevent
damage to the guard; place a sling under the
head near the column on the spindle side.
2. Loosen the two binders clamping the head to
the column and raise the head to the desired
height. Move the safety collar to a position
under the head by loosening the two set
screws, sliding the collar up, and relocking
setscrews.
3. Remove the sling and clamp the head in
position.
4. Using the crane and sling, unlock the table
binder and raise the table height enough to
install the table raising rack.
5. Install the rack by placing it in the notched
area in the lower collar and driving the roll pin
through the hole in the rack and through both
ears on the collar .
6. Position the rack to engage the table raising
gearing and lower the table until the rack
engages the rack pinion.
7. Lower the crane to put slack in the sling,
engage the table raising lever and lower the
table on to the rack. Visually align the table
with the base, lock the table binder and
remove the sling.
SPINDLE TABLE MODELS
In the case of spindle table models, the legs are not
attached to the table, they are packed sep arately.
To assemble the legs to the spindle table, carefully
support machine on forklift tines or other temporary
supports and bolt legs securely into position. It is
imperative that a spindle table be carefully leveled.
Use a precision level, and adjust the level using the
jackscrews provided in the legs. Lag machine to
floor through holes provided in leveling screws (3/8"
dia. lag screws).
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:
1. Be sure quill lock handle (Figure 2) is loose.
2. 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.
FIGURE 2
Quill Fit Up Adjustment
QUILL RETURN SPRING ADJUSTMENT
Spring tension for return of 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)
(Figure 3) 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.)
8
Reset lockscrew (A), 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
(Figure 3) and loosen lockscrew (A). Let spring
unwind slowly , by allowing cam to turn in hand.
2. Loosen setscrew (C) and remove nut (D) on
bottom of depth stop rod. Unscrew and remove
depth stop.
3. Hold quill assembly and remove the turret pinion
shaft (E). Entire quill assembly will slide out of
head.
To change spindles, follow the above steps, then
(Figure 4):
1. Loosen setscrew in collar (J). To reach this
screw , insert a 5/32" hex head wrench.
2. With a hard rubber mallet or block of wood, tap
spline end of spindle. The spindle, with bearing
(K), will come out of quill.
3. Use an arbor press to remove bearing (K).
4. To replace spindle, reverse above procedure.
5. When replacing collar (J), remove all end play
from spindle.
6. When replacing quill in head casting, rotate
spindle, if necessary , to engage spline in pulley
driver.
7. Remove lock ring (F) and cover plate (G)
(Figure 3) from spring housing and make
certain tongue on return spring is properly
inserted in slotted end of pinion shaft. Replace
cover and adjust spring tension as instructed
under heading "QUILL RETURN SPRING
ADJUSTMENT."

Quill Removal
LUBRICATIONS
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.
FIGURE 4

4. IMPORTANT: The hub area of variable speed
pulleys should be oiled with a light lubricant
such as SAE 10W or automatic transmission
oil every 90 days.
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.
7. When equipped with mechanical power feed
unit, periodically coat the gears with a good
open gear lubricant.
DRILL PRESS OPERATIONS
Familiarize yourself with all operating controls
before attempting use of this machine.
CONTROLS (see Figure 5)
1. The spindle (A) in this machine has a No. 3
Morse Taper.
2. A depth stop rod (B) is provided to control hole
depth and to prevent 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. A safety collar (E) is provided to prevent head
from falling when locks are released.
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 provide assistance in determining proper drill speed.
8. On all 1200HD models, a knob (I) is used to
change speed.
9. On production table models, binder (J) locks
the table to the column and handle (H) is used to
raise and lower the table.
10. The model 1200HD is provided with an ACinverter (K) which is pre-programmed from the
factory and requires no changing or adjustment.
OPERATING TIPS
1. Determine drill size, inspect for sharpness,
insert 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 prevent marring table
surface and eliminate splintering at breakthrough
point. Lock table securely to prevent movement.
3. Prevent the work from being torn from
operator's hand, by always securing the workpiece,
jig, fixture, or holding device 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 devices to the table to prevent 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 1A, 1B, 2, and 3 on pages 25 thru 28 for
recommendations.) If drill press is the step pulley
type, raise door and set drive belt in proper ration
position. If the machine is a variable speed model,
turn machine on the turn control cam to proper
speed. (NEVER attempt speed adjustment of
variable speed machines unless machine is running.) Turn machine off.
