SAFETY RULES
WARNING: Some dust created by power sanding, sawing, grind-
ing, 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 paints.
•Crystalline silica from bricks and cement and other masonry
products.
•Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures vary, 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. Always wear OSHA/NIOSH approved, properly fitting
face mask or respirator when using such tools.
WARNING: Always follow proper operating procedures as
defined in this manual — even if you are familiar with use of this
or similar tools. Remember that being careless for even a fraction
of a second can result in severe personal injury.
BE PREPARED FOR JOB
•Wear proper apparel. Do not wear loose clothing, gloves, neck-
ties, rings, bracelets or other jewelry which may get caught in
moving parts of machine.
•Wear protective hair covering to contain long hair.
•Wear safety shoes with non-slip soles.
•Wear safety glasses complying with United States ANSI Z87.1.
Everyday glasses have only impact resistant lenses.They are
NOT safety glasses.
•Wear face mask or dust mask if operation is dusty.
•Always wear ear protection. The work area may include expo-
sure to excessive noise levels which will require necessary ear
protection.
•Be alert and think clearly.Never operate power tools when
tired, intoxicated or when taking medications that cause
drowsiness.
PREPARE WORK AREA FOR JOB
•Keep work area clean. Cluttered work areas invite accidents.
•Do not use power tools in dangerous environments. Do not
use power tools in damp or wet locations. Do not expose
power tools to rain.
•Work area should be properly lighted.

GENERAL SAFETY INFORMATION (CONTINUED)
•Always be sure machine is anchored securely to the floor or
bench.
•Keep visitors at a safe distance from work area.
•Keep children out of workplace. Make workshop childproof.
Use padlocks, master switches and remove switch keys to pre-
vent any unintentional use of power tools.
TOOL SHOULD BE MAINTAINED
•Always unplug tool prior to inspection.
•Consult manual for specific maintaining and adjusting procedures.
•Keep tool lubricated and clean for safest operation.
•Remove adjusting tools. Form habit of checking to see that
adjusting tools are removed before switching machine on.
•Keep all parts in working order. Check to determine that the
guard or other parts will operate properly and perform their
intended function.
•Check for damaged parts. Check for misalignment of moving
parts, binding, breakage, mounting and any other condition
that may affect a tool’s operation.
•A guard or other damaged part should be properly repaired or
replaced. Do not perform makeshift repairs. (Use parts list
provided to order replacement parts.)
•Never brush away chips while the machine is in operation. All
clean up should be done when the machine is stopped.
•Never modify machine without consulting manufacturer.
•Use sharp cutters and keep the tool clean for safest operation.
KNOW HOW TO USE TOOL
•Use right tool for job. Do not force tool or attachment to do a
job for which it was not designed.
•Disconnect tool when performing maintenance.
•Avoid accidental start-up. Make sure that tool switch is in OFF
position before connection to air supply.
•Do not force tool. It will work most efficiently at the rate for
which it was designed.
•Leave hands free to operate machine. Protect hands from
possible injury.
•Never leave a tool running unattended.Turn the power off and
do not leave tool until it comes to a complete stop.
•Do not overreach. Keep proper footing and balance.
•Always avoid contact with coolant; guard the eyes, especially.
•All workpieces must be clamped to work table when using tap-
ping machine. It is unsafe to use your hands to hold any work-
piece.
•Keep hands away from moving parts.
•Know your tool. Learn the tool’s operation, application and spe-
cific limitations.
CAUTION: Think safety! Safety is a combination of operator com-
mon sense and alertness at all times when tool is being used.

Refer to Figure 5.
•Remove tape securing keys from spindle motor body.
•Insert spindle motor into bracket of control arm; make sure
keys on spindle motor are seated completely into the bracket.
•Make sure that exhaust hose fittings of spindle motor and
control arm are on the same side.
•Secure spindle motor tightly into bracket using both socket head
bolts.
•Attach air hose fitting securely to spindle motor.
MOUNT LUBRICATION UNIT
Refer to Figure 6.
•Remove front cover of lubricator body by lifting tab at top of
cover and pulling cover outward.
•Insert the two mounting bolts as shown.
•Attach mounting bracket to the back of lubrication body with
two nuts.
•Replace front cover.

MODELS 80422 AND 80423
•Attach exhaust hose to exhaust fitting of spindle motor and
control arm fitting.
•Secure in position with clamps.
OPERATION
PREPARATION AND ADJUSTMENTS
Refer to Figures 11 -14
Caution: Add lubricant BEFORE connecting air supply to lubrication
unit.
•Add lubricant (ISOVG32 or DIN51524 type oil) to the lubricator
body. Unscrew the oil fill plug and add approximately 8-10
ounces of oil. Replace plug and tighten securely.
•Machine is supplied with a 3⁄8”quick connect. Connect air sup-
ply hose to quick connect. Models 80410 and 80411 require a
minimum 5HP air compressor. Models 80412 and 80413 require
a minimum 10HP air compressor.
•Pull the pressure adjusting knob up and adjust air pressure to
90 PSI (6 kgf/cm 2). Rotate clockwise to increase pressure, coun-
terclockwise to decrease pressure. If tapping 5⁄16” (8mm) or larg-
er, adjust the air pressure to 115 PSI (8 kgf/cm 2). After adjust-
ing, press knob down to its locked position.
Caution: Do not exceed 135 PSI (9.5 kgf/cm2).This will cause
bursting of the filter and lubricator bowls.
•Depress and hold the operating lever of the spindle.While the
spindle is operating, check the oil flow rate through the sight
glass on top of the lubricator body.The lubricator should oper-
ate at 3-5 drops/minute. Rotate the oil adjusting screw clock-
wise to decrease the oil flow rate; counterclockwise to increase
the oil flow rate.
•Slide tap into tap holder (not included) until tap locks in place.
Tap can be removed by simultaneously depressing flange and
pulling out tap.
•Insert tap holder with tap into spindle. Pull up spindle chuck
sleeve, insert tap holder with tabs aligned to slots in chuck
sleeve, and then release sleeve.

OPERATION (CONTINUED)
•Models 80422 and 80423 – These models have two speed
motors. Spindle motor speed can be changed by grasping
spindle motor sleeve, pulling downward so that pin is out of
the notch in the body, rotating sleeve to the other notch and
then releasing the sleeve so that pin seats in the notch.
Caution: Never change speed while spindle motor is in operation.
OPERATING PROCEDURE
Refer to Figures 4, 5 and 12.
•Bring the spindle motor with tap to the hole to be tapped.
•Place the tip of the tap on the hole and depress the operating
lever.The tap will self-center and begin cutting. Let the tap arm
guide the tap into the hole.
•After tapping to the required depth, press the reverse button
while also depressing the operating lever.The tap will reverse
out from the hole.
•If the tap holder “clicks” or “ratchets”, the tap holder clutch
torsion needs to be adjusted.
To adjust tap holder clutch (see Figure 13):
•Remove the spring clip from the groove of the tap holder.
•Turn the notched nut clockwise to increase torsion, counter-
clockwise to decrease torsion.
•Replace spring clip into the groove of the tap holder.
•Spindle motor speed can be adjusted by turning the screw
above the reverse button (see Figures 4 and 5).
•Consult machinery reference books or your machine tool deal-
er for information concerning tap lubricant types, tapping
speeds and tap types.
MAINTENANCE
WARNING: Make certain that unit is disconnected from air supply
before attempting to service or remove any component.
•Keep machine and workshop clean. Keep mechanisms clean
and free of foreign particles.
•Bearings located in arms are permanently lubricated and
require no further lubrication
LUBRICATION UNIT
Refer to Figure 15.
•Always keep the lubricator oil reservoir full and make sure
lubricator operates at 3-5 drops/minute.
•FILTER VALVE will open automatically and discharge when air
pressure is less than 10 PSI (0.7 kgf/cm 2). Filter valve can also be
operated manually – discharge filter daily.
•LUBRICATOR RESERVOIR has manual drain.
ACCESSORIES
•Contact your Palmgren distributor for tap holders, angle motor
brackets and drill chuck attachments.
