SAFETY RULES
As with all machines, there is a certain amount of hazard involved with the use of this cut-off saw. 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 this machine.
Electrical grounding. Make certain that the machine frame is electrically grounded and that a ground lead is
included in the incoming electrical service. In cases where a cord and plug are used, make certain that the
grounding plug connects to a suitable ground. Follow the grounding procedure indicated in the National
Electrical Code.
Eye safety. Wear an approved safety shield, goggles, or glasses to protect eyes. (NOTE: Common
eyeglasses are only impact-resistant, they are not safety glasses.)
Personal protection. Before operating the machine, remove tie, rings, watch and other jewelry and roll up
sleeves above the elbows. Remove all loose outer clothing and confine long hair. Protective type footwear
should be used. 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.
Guards. Keep the machine guards in place for every operation for which they can be used. If any guards are
removed for maintenance, DO NOT OPERATE the machine until the guards are reinstalled. The blade guard
is air actuated; it is also a clamp for stock. Never shut off or disconnect air while operator or bystanders are
near guard.
Work area. Keep the floor around the machine clean and free of scrap material, saw dust, oil and other
liquids to minimize the danger of tripping or slipping. Be sure the table is free of all scrap, foreign material
and tools before starting to cut. Make certain the work area is well lighted and that a proper exhaust system is
used to minimize dust. 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. Provide adequate work space
around the machine.
Avoid accidental starting: Make certain motor switch is in off position before connecting power to the
machine.
Operator position. Maintain a balanced stance and keep your body under control at all times.
Housekeeping. Before turning on machine, remove all extra equipment such as keys, wrenches, scrap, and
cleaning rags away from 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.
Disconnect all power sources (both air and electric) before performing any service, maintenance,
adjustments or when changing blades. When the air line is disconnected or turned off, the guard will
immediately drop down to the table. Keep hands clear of guard at all times. A machine under repair should be
RED TAGGED to show it should not be used until the maintenance is complete.
Maintain cutting tools in top condition. Keep blades sharp and clean for safe and best performance. Dull
tools increase noise levels and can cause kickbacks and glazed surfaces. Check the condition and
adjustment of the tools before making any cuts.
Hand safety. Keep hands outside the machine. Do not clear chips and sawdust with hands; use a brush.

Job completion. If the operator leaves the machine area for any reason, the cut-off saw should be turned
"off" and the blade should come to a complete stop before his departure. In addition, if the operation is
complete, he should clean the saw and the work area. NEVER clean the saw with power "on" and never use
the hands to clear sawdust and debris; use a brush.
Replacement parts. Use only Powermatic or factory authorized replacement parts and accessories;
otherwise the warranty and guarantee is null and void.
Misuse. Do not use this Powermatic cut-off saw 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 or damage which
may result from that use.
If you are not thoroughly familiar with the operation of cut-off saws, 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.
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).

RECEIVING
Open shipping crate and check for shipping
damage. Report any damage immediately to
your distributor and shipping agent. Before using
the cut-off saw, read the instruction manual
thoroughly for assembly, maintenance and safety
instructions.
Contents of crate:
1 Cut-off saw
1 Handwheel
1 Toolbox containing:
1 hex wrench set
1 socket wrench
1 open-end wrench set
1 Manual
1 Warranty card
INSTALLATION & ASSEMBLY
1. Lift the machine with a hoist or forklift, using
a sling through the lifting eye on top the
machine, shown in Figure 3. Make sure the
capacity of the lifting unit is sufficient to
safely lift this size machine.
2. The cut-off saw (with any roller table
extensions) should be located in an area that
is well-lit, with enough room around it for
loading and off-loading stock and general
servicing of the machine.
3. The saw cabinet should be bolted to the floor
through the holes at the four corners, using
high quality lag screws.
Unpainted surfaces, such as the table and fence,
have been given a protective coating at the
factory. This should be removed with a soft rag
moistened with a good commercial solvent. Do
not use acetone, lacquer thinner, gasoline or any
flammable solvents. Do not use an abrasive pad.
HANDWHEEL
Install the handwheel onto the threaded rod as
shown (Fig. 3).

ELECTRICAL CONNECTIONS
WARNING: Electrical connections must
be made by a qualified electrician in
compliance will all relevant codes. The
machine must be properly grounded to
help prevent electrical shock and
possible death.
A power plug is not provided with the COS18.
You may either connect one, or "hard-wire" the
machine directly to your electrical panel provided
there is a disconnect near the machine.
Consult electrical schematic on page 34 for
further clarification of wiring setup.
This machine must be grounded. Grounding
provides a path of least resistance to help divert
current away from the operator in case of
electrical malfunction.
Make sure the voltage of your power supply
matches the specifications on the motor plate of
the machine.
After wiring, disconnect machine from power
source, open the blade access door, remove the
internal clear panel, and remove the blade (see
"Installing/Changing Blade"). Re-connect the
power and turn on the saw motor (see "Operating
Controls"). Observe the rotation of the arbor – it
should rotate counterclockwise on the LH model,
clockwise on the RH model. If it does not, turn off
the machine, disconnect power, and switch any
two of the three electrical leads.
NOTE: A label is affixed to the internal clear
panel to help identify proper rotation.
EXTENSION CORDS
If an extension cord is necessary, make sure the
cord rating is suitable for the amperage listed on
the machine's motor plate. An undersized cord
will cause a drop in line voltage resulting in loss
of power and overheating.
The chart in Figure 4 shows the correct size cord
to use based on cord length and nameplate amp
rating. If in doubt, use the next heavier gauge.
The smaller the gauge number, the heavier the
cord.

DUST COLLECTION
Powermatic recommends the use of a dust
collection system with this cut-off saw. The
collector should have sufficient capacity (600
CFM) for this size machine.
Mount the dust collector via a 4" hose to the
outlet on the blade access door.
OPERATING CONTROLS
Control buttons are in two locations on the saw,
and are shown in Figure 5. A main start and stop
button is located at the back of the table top. An
emergency stop button is also found on the front.
The air-control switch, in both locations, starts the
flow of air to the cylinder.
INSTALLING / CHANGING BLADE
1. Disconnect machine from power source.
WARNING: Never attempt to open blade
access door until blade has come to a
complete stop.
2. Open the saw blade access door by
loosening the screws.
3. Remove the clear panel guarding the blade
(Fig. 6) by loosening the screws and lifting
up on the panel.
4. Lock the arbor by pulling the lever (Fig. 8).
4. Loosen hex screw (Fig. 7) on the arbor.
(counterclockwise to loosen on the LH
model; clockwise on RH model). Remove
hex screw and outer flange from the arbor.
5. Mount the blade on the arbor as shown,
making sure the teeth are pointed in the
proper direction – the teeth at top of blade
should point toward rear of machine.
6. Re-install outer flange and screw, and
tighten securely.

7. Re-install clear panel and close blade access
door, fastening it securely. NOTE: A sensor
switch on the door will automatically shut
down the saw if the door is opened while the
blade is moving.
WARNING: Do not reconnect power, air
or electric, without internal clear panel in
place and door securely fastened with
screws.
AIR SUPPLY
The correct air pressure for the COS18 saw is 70
PSI. Attach the hose from your air source to the
machine's air valve as shown in Figure 9.
SQUARING THE FENCE
The best way to square the fence is to make
sample cuts. Using a square, check the end of a
board after it has been chopped. If the cut is not
square, proceed as follows:
1. Loosen one of the bolts on the fence and
lightly tap the fence with a block or mallet.
2. Retighten the bolt, and make another cut.
Repeat as necessary until fence is square.
INSTALLING ROLLER TABLES
(OPTIONAL)
Four-foot and 8-foot roller tables are available as
accessories to your cut-off saw. The roller tables
can be used as infeed or outfeed tables and
mounted to either side of the saw. The terms
"Right Hand" and "Left Hand" Model are
determined by the location of the blade in
reference to the main table. (The cover of this
manual shows a left-hand model.)

To mount roller tables to saw:
1. Mount an angle bracket to the pre-drilled
holes in the side of the saw cabinet with four
M8 x 20 hex cap screws and four M8 flat
washers (Fig. 10). Do not fully tighten yet.
2. Place the roller table upside down on a flat
surface and attach the leg assemblies with
four M8 x 25 hex cap screws, eight M8 flat
washers, and four M8 hex nuts per leg
assembly (Fig. 11).
3. Screw an adjustable foot pad into each leg
as shown in Figure 12.
4. Flip the roller table right-side up and mount it
to the angle bracket on the cabinet as shown
in Figure 10. Use two M8 x 25 screws, four
M8 flat washers and two M8 hex nuts. Do not
fully tighten yet.

8-FOOT TABLE GUIDE
1. The 8-foot table comes with a guide and
scale. The guide should be mounted to the
edge of the table with six M8 x 27 square
head bolts, six M8 flat washers and six M8
hex nuts (Fig. 13).
2. Attach the three stops to the 8-foot table
guide (Fig. 13). These stops can be slid to
any point along the guide and secured by
tightening the lock levers.
LEVELING & ALIGNING ROLLER TABLES
Each roller table must now be leveled with the
main saw table and aligned with the fence. (The
fence must be square with blade – see "Squaring
the Fence", page 11.)
WARNING: Disconnect saw from both
air and electric power sources.
1. Select a piece of scrap board with a good
straight edge, 4 to 6 feet in length.
2. Raise the blade guard and keep it raised.
Place the board, straight edge down, on the
saw table surface and allow it to extend to
the second or third roller of the roller table
(Fig. 14).
3. Level the roller table by loosening the hex
nut on the foot pad and screw the foot pad in
or out. (see Fig. 12).
4. When roller table and main table are level,
tighten the nuts on the foot pads.

5. Now place the board flush against the fence
and against the rail of the roller table(s). If
necessary, shift a roller table horizontally to
bring it in line with the fence.
6. When final adjustments have been made
and re-checked on the roller tables, tighten
all screws/nuts connecting the roller tables to
the angle brackets.
CAUTION:
Never adjust the outfeed
table level higher than the level of the
machine table surface.
ADJUSTMENTS
WARNING:
Disconnect
all
power
sources, both air and electric, prior to
making adjustments.
BLADE TRAVEL
To adjust the speed by which the saw blade (and
the clamp) travel up and down, open the cabinet
door and locate the upper and lower pressure
regulating valves which are attached to the air
cylinder (Fig. 15). Turning these will regulate the
travel speed of the blade and clamp. The clamp
will lower during the blade's upstroke, and rise
during the blade's downstroke.
The top valve (shown in Fig. 15) adjusts the
speed of the blade's downstroke (and the speed
of the clamp as it rises back up). Turn the knob
counterclockwise to increase the speed, clockwise
to decrease. When the speed is satisfactory, lock
the setting by tightening the knurled nut.
Repeat for the lower valve, which adjusts the
speed of the blade's upstroke (and the lowering of
the clamp).
CLAMP HEIGHT ADJUSTMENT
The distance between the stock clamp and the
workpiece can be adjusted by turning the
handwheel (Fig. 16). Line up the red indicator
plate with the measurement on the scale. Ideally,
there should be a space of 1/8" between the
clamp and the workpiece. After setting the clamp
height, move the hex nut downward and tighten
against the casting as shown – this will prevent
your setting being altered by machine vibrations.
IMPORTANT: The clamp height adjustment must
be made each time the workpiece size changes.

BELT REPLACEMENT
1. Release tension on the v-belt and remove
old belt.
2. Make sure the new belt is properly situated
into the v-grooves of the pulley.
3. Tension new belt.
OPERATION
WARNING: Do not place your hands
close to the guard/clamp at any time
during operations. All guards must be
installed before using the machine.
1. Start the motor and the air supply.
2. Adjust height of clamp so it clears the
workpiece by about 1/8".
3. Set the appropriate stop(s) on the roller table
and load the stock on to the machine from
the infeed side.
4. When the stock is situated, press the foot
pedal to make the cut.
WARNING: If the motor is shut off, but
the air is still on, the clamp will still be in
raised position. Turning off the air will
cause the clamp to lower suddenly. Keep
hands clear! Re-starting the air will cause
the clamp to rise suddenly.
MAINTENANCE
Frequently drain any water out of the pneumatic
valve.
The exposed metal areas on the table and fence
should be kept clean and free from rust. Apply a
coat of paste wax as needed. Another option is to
briskly rub talcum powder into the surface with a
clean blackboard eraser.
Bearings should be greased through the fitting on
the center of the arbor housing (Fig. 18).
