WARNING: 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 paints,
· crystalline silica from bricks and cement and other masonry products, and
· 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 specially designed to filter out microscopic particles.
GENERAL SAFETY RULES
WARNING: READ AND UNDERSTAND ALL INSTRUCTIONS. Failure
to follow all instructions listed below, may result in electric shock, fire and/or
serious personal injury.
SAVE THESE INSTRUCTIONS.
WORK AREA
1. Keep your work area clean and well lit. Cluttered benches and dark
areas invite accidents.
2. Do not operate power tools in explosive atmospheres, such as in
the presence of flammable liquids, gases, or dust. Power tools create
sparks which may ignite the dust or fumes.
3. Keep bystanders, children, and visitors away while operating a
power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Double insulated tools are equipped with a polarized plug (one
blade is wider than the other). This plug will fit in a polarized outlet only
one way. If the plug does not fit fully in the outlet, reverse the plug. If it
still does not fit, contact a qualified electrician to install a polarized
outlet. Do not change the plug in any way. Double Insulation
eliminates the need for the three wire grounded power cord and
grounded power supply system.
2. Avoid body contact with grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is grounded.
3. Don’t expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord to carry the tools or pull
the plug from an outlet. Keep cord away from heat, oil, sharp edges or
moving parts. Replace damaged cords immediately. Damaged cords
increase the risk of electric shock.
5. When operating a power tool outside, use an outdoor extension
cord marked “W-A” or “W”. These cords are rated for outdoor use and
reduce the risk of electric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing, and use common sense when
operating a power tool. Do not use tool while tired or under the
influence of drugs, alcohol, or medication. A moment of inattention while
operating power tools may result in serious personal injury.
2. Dress properly. Do not wear loose clothing or jewelry. Contain long
hair. Keep your hair, clothing, and gloves away from moving parts.
900005 - 11-30-01.qxd 2/12/02 10:45 AM Page 2
3
Loose clothes, jewelry, or long hair can be caught in moving parts.
3. Avoid accidental starting. Be sure switch is OFF before plugging in.
Carrying tools with your finger on the switch or plugging in tools that have
the switch ON invites accidents.
4. Remove adjusting keys or wrenches before turning the tool ON. A
wrench or a key that is left attached to a rotating part of the tool may result in
personal injury.
5. Do not overreach. Keep proper footing and balance at all times.
Proper footing and balance enable better control of the tool in unexpected
situations.
6. Use safety equipment. Always wear eye protection. Dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for
appropriate conditions.
TOOLS USE AND CARE
1. Use clamps or other practical way to secure and support the
workpiece to a stable platform. Holding the work by hand or against your
body is unstable and may lead to loss of control.
2. Do not force tool. Use the correct tool for your application. The
correct tool will do the job better and safer at the rate for which it is
designed.
3. Do not use tool if switch does not turn it ON or OFF. A tool that
cannot be controlled with the switch is dangerous and must be repaired.
4. Disconnect the plug from the power source before making any
adjustments, changing accessories, or storing the tool. Such preventive
safety measures reduce the risk of starting the tool accidentally.
5. Store idle tools out of reach of children and other untrained
persons. Tools are dangerous in the hands of untrained users.
6. Maintain tools with care. Keep cutting tools sharp and clean.
Properly maintained tools, with sharp cutting edges are less likely to bind
and are easier to control.
7. Check for misalignment or binding of moving parts, breakage of
parts, and any other condition that may affect the tool’s operation. If
damaged, have the tool serviced before using. Many accidents are
caused by poorly maintained tools.
8. Use only accessories that are recommended by the manufacturer
for your model. Accessories that may be suitable for one tool may become
hazardous when used on another tool.
SERVICE
1. Tool service must be performed only by qualified repair personnel.
Service or maintenance performed by unqualified personnel may result in a
risk of injury.
2. When servicing a tool, use only identical replacement parts. Follow
instructions in the Maintenance Section of this manual. Use of
unauthorized parts or failure to follow Maintenance Instructions may create a
risk of electric shock or injury.
SPECIFIC SAFETY RULES AND SYMBOLS
1. Hold tool by insulated gripping surfaces when performing an
operation where the cutting tool may contact hidden wiring or its own
cord. Contact with a “live” wire will also make exposed metal parts of the
tool “live” and shock the operator.
2. Always disconnect trimmer from power source before making adjustments or changing bits.
900005 - 11-30-01.qxd 2/12/02 10:45 AM Page 3
4
3. Always be sure collet nut is securely tightened to prevent the bit from
slipping during use.
4. Make certain that the workpiece is rigidly held in desired position and
free of obstructions.
5. Be sure cord is free and will not “hang up” during trimming operation.
6. Be sure trimmer bit is clear of work before starting motor.
7. Maintain firm grip on trimmer when starting to resist starting torque.
8. Keep hands clear of cutter when motor is running to prevent personal
injury.
9. Always hold the trimmer firmly and against the work during trimming
operation.
10. Keep cutting pressure constant. Do not overload the trimmer.
11. Be sure motor has completely stopped before setting machine down
between operations.
12. Never touch trimmer bits after use, since they may be extremely hot.
13. Never tighten collet nut without bit inserted. This will deform collet
making it impossible to insert bit.
14. Do not use Laminate Trimmer motor without the Laminate Trimmer
Base installed: loss of control could result, causing personal injury or
damage to work.
15. Some wood contains preservatives which can be toxic. Take extra
care to prevent inhalation and skin contact when working with these
materials. Request, and follow, any safety information available from your
material supplier.
16. WARNING: There are certain applications for which this tool was
designed. Porter-Cable strongly recommends that this tool NOT be modified
and/or used for any application other than for which it was designed. If you
have any questions relative to its application DO NOT use the tool until you
have written Porter-Cable and we have advised you.

MOTOR
Many Porter-Cable tools will operate on either D.C., or single phase 25 to 60
cycle A.C. current and voltage within plus or minus 5 percent of that shown
on the specification plate on the tool. Several models, however, are designed
for A.C. current only. Refer to the specification plate on your tool for proper
voltage and current rating.
CAUTION: Do not operate your tool on a current on which the
voltage is not within correct limits. Do not operate tools rated A.C.
only on D.C. current. To do so may seriously damage the tool.
EXTENSION CORD SELECTION
If an extension cord is used, make sure the conductor size is large enough to
prevent excessive voltage drop which will cause loss of power and possible
motor damage. A table of recommended extension cord sizes will be found
in this section. This table is based on limiting line voltage drop to 5 volts (10
volts for 230 volts) at 150% of rated amperes.
If an extension cord is to be used outdoors it must be marked with the suffix
W-A or W following the cord type designation. For example – SJTW-A to
indicate it is acceptable for outdoor use.

FUNCTIONAL DESCRIPTION
FOREWORD
Porter-Cable Laminate Trimmers are designed for flush and bevel trimming
laminated plastics, phenolics, and other similar materials having a bonding
agent too hard to be trimmed with ordinary tools.
The Tilt-Base model allows trimming into corners inaccessible to standard
trimmers and to trim laminated surfaces joining at angles of 45° to 90°. This
feature eliminates the need for hand-trimming in many applications.
The Off-Set Base Trimmer is designed for trimming into the corner of a back
splash and trimming narrow ledges which are already mounted against a wall
or another surface.
The Underscribe Base is designed for making accurate “butt” joints in
laminated plastics, phenolics and other similar materials. The Underscribe
Base is used with the Model 7301 Trimmer Motor and the 43109 Trim Bit.
SELECTING THE BIT
These trimmers are equipped with a
1
/4" diameter collet to accept laminate
trimming bits having
1
/4" diameter shanks. Bits are available as an accessory.
MODEL 7301 MOTOR UNIT
All laminate trimmers covered by this manual incorporate Model 7301 Motor
Unit and are operated as follows:
TO START AND STOP MOTOR

NEVER TIGHTEN COLLET WITHOUT
BIT INSERTED, TO DO SO MAY CAUSE
DAMAGE TO COLLET.
4. Position base (A) Fig. 15, to motor (B) and secure using locking screw
(E), spring (D) and washer (C).
NOTE: Orient spring with small end against head of locking screw.
ADJUSTING BIT EXPOSURE
CAUTION: DISCONNECT TOOL FROM POWER SOURCE.
1. Loosen base locking screw (E) Fig. 15, approximately one-quarter of a
turn.
2. Turn depth adjusting wheel (F) Fig. 15, counterclockwise (looking at top
of wheel) to lower bit until it just touches the guide plate.

ADJUSTING GUIDE PLATE
The Underscribe Trimmer Base is equipped with an adjustable guide plate
(see Fig. 16). The guide plate is adjusted by rotating the eccentric, using a
special wrench that is supplied with the Trimmer Base. To adjust guide,
proceed as follows:
1. Make a trial cut using scrap material and check fit.
2. CAUTION: DISCONNECT TOOL FROM POWER SOURCE.
3. Turn eccentric to correct fit-up:
If joint is TOO LOOSE (crack between the two pieces of laminate), turn
eccentric clockwise.
If joint to TOO TIGHT (laminate will not snap into place), turn eccentric
counterclockwise.

4. Repeat Steps 1 through 3 as
required to achieve a good fitup.
USING THE
UNDERSCRIBE
TRIMMER
The bottom plate of the
Underscribe Trimmer has a
guide lip (see Fig. 17). This
guide lip is moved along an
installed piece of laminate as the trimmer bit cuts the mating piece of
laminate.
The “butt” joint is commonly used in the construction of face frames.
Proceed as follows to install a laminate covering on a face frame. Similar
procedures would be required for making any “butt” joint.
CAUTION: ALWAYS WEAR SAFETY GLASSES WHILE OPERATING A
LAMINATE TRIMMER.

1. Cut the pieces of
laminate covering to rough
size and apply contact
cement to the face frame
and the laminate pieces in the normal manner.
NOTE: Cut the rail covering approximately 1" longer than the rail (to
allow material for trimming).
2. Apply the laminate to all stiles.
3. Position the laminate to a rail with at least
1
/4", and no more than 3/4",
overlapping each stile (see Fig. 18). Use a roller to secure the center section
of the laminate to the rail. Leave at least 4" of the laminate loose, at both
ends of the rail (Do not
roll down).
4. Securely clamp
the face frame
assembly to the
worktable to prevent
movement during the
trimming operation.

5. Position the underscribe trimmer onto the face frame so that the top
(see Fig. 19), is against the edge of the stile.
NOTE: The trimmer should be to the right of the rail, so that the
cutting action will move from right to left (see Fig. 19).
6. Verify that bit is clear of foreign objects and that cord will not hang on
any obstructions.
7. Grasp motor firmly to resist starting torque and move switch button to
ON position.
8. Allow motor to reach full-speed. Feed trimmer right to left with a smooth
steady motion.
NOTE: The tapered edge of the underscribe base will slide
underneath the rail covering, lifting the laminate into the cutter.
9. After completing the cut, move the switch button to the OFF position
and allow the motor to come to a complete stop before laying the trimmer
down.
10. Press the rail end into position and roll down.
11. Repeat the above process as necessary to complete the face frame.
MAINTENANCE
KEEP TOOL CLEAN
Periodically blow out all air passages with dry compressed air. All plastic
parts should be cleaned with a soft damp cloth. NEVER use solvents to
clean plastic parts. They could possibly dissolve or otherwise damage the
material.
CAUTION: Wear safety glasses while using compressed air.
FAILURE TO START
Should your tool fail to start, check to make sure the prongs on the cord
plug are making good contact in the outlet. Also, check for blown fuses or
open circuit breakers in the line.
