GENERAL SAFETY RULES*

Read all instructions Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term "power tool" in all of the warnings listed below refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

1) Work area safety a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.

b) 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.

c) Keep children and bystanders away while operating a power tool.

Distractions can cause you to lose control

2) Electrical safety a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power

tools. Unmodified plugs and matching outlets will reduce risk of electric shock b) Avoid body contact with earthed or grounded surfaces such as

pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp

edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

e) When operating a power tool outdoors, use an extension cord

suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

3) Personal safety a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired

or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

b) Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Avoid accidental starting. Ensure the switch is in the off-position

before plugging in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.

4

*The text used in the General Safety Rule section of this manual is verbatim, as required, from the applicable UL60745 3rd edition standard.

GENERAL SAFETY RULES*

continued d) Remove any adjusting key or wrench before turning the power tool

on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jewellery. Keep your

hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used.

Use of these devices can reduce dust-related hazards.

4) Power tool use and care a) Do not force the power tool. Use the correct power tool for your

application. The correct power tool will do the job better and safer at the rate for which it was designed.

b) Do not use the power tool if the switch does not turn it on and off.

Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source before making any

adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to

operate the power tool. Power tools are dangerous in the hands of untrained users.

e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired

before use. Many accidents are caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits etc., in accordance with these instructions and in the manner intended for the particular type of power tool, taking into account the working

conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5) Service a) Have your power tool serviced by a qualified repair person using only

identical replacement parts. This will ensure that the safety of the power tool is maintained.

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.

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

SCRIBING OF

BACKSPLASH TO WALL

APPLICATION – Trimming front edge of

3 /

" vertical backsplash. This is an operation standard trimmers with round or square bases are unable to do without the use of a special bit.

APPLICATION – Trimming into and out of installed backsplash corner with little or no hand trimming required.

APPLICATION – Accurately scribing the back side of a preassembled panel or post-formed backsplash. Once the lip is accurately scribed, the trimmed portion is then pushed against the wall and mated exactly.

Front edge of trimmer is guided against wall.

Triangular base enables complete corner trimming with backsplash in place.

Self-piloted bit guides trimmer for one-pass trimming every time.

Triangular base enables trimming with backsplash in place.

OPERATION – Trimming 3 / 4

" backsplash with the new Porter-Cable Offset Laminate

Trimmer fitted with a solid carbide selfpiloted bit.

OPERATION – The new Porter-Cable

Offset Trimmer will trim into and out of 90° corners with ease using selfpiloted bit.

Self-piloted bit follows every trimmer movement to create exact reproduction of wall surface in one pass!

Maintain 3 /

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

Fig. 16 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.
