SAFETY INSTRUCTIONS

GROUNDING INSTRUCTIONS

This tool should be grounded while in use to protect the operator from electric shock. The tool is equipped with an approved three-conductor cord and three-prong grounding type plug to fit the proper grounding type receptacle. The green (or green and yellow) conductor in the cord is the grounding wire. Never connect the green (or green and yellow) wire to a live terminal.

If your unit is for use on less than 150 Volts, the power cord is equipped with a plug that has two flat, parallel current-carrying prongs and one longer, round or “U”-shaped, ground prong which requires a mating 3conductor grounded type receptacle, as shown in Fig. 1.

An adapter, shown in Fig. 2, is available for connecting 3-prong grounding type plugs that are used on units less than 150 Volts to 2-prong receptacles. THIS ADAPTER IS NOT ALLOWED IN CANADA. The green colored rigid ear, lug, etc., must be connected to a permanent ground such as a properly grounded outlet box, as shown in Fig. 2.

If your unit is for use on 150 to 250 Volts, the power cord is equipped with a plug that has two flat current carrying prongs in tandem, and one round or “U”-shaped, longer ground prong, as shown in Fig. 3. This plug is used only with the proper mating 3conductor grounding type receptacle, as shown in Fig. 3. No adapter is available for this type plug.

IN ALL CASES, MAKE SURE THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED.

NEVER REMOVE GROUNDING PRONG FROM POWER PLUG.

EXTENSION CORDS

Use only three-wire extension cords which have three-prong grounding-type plugs and three-pole receptacle which accept the tool’s plug. Replace damaged or worn cord immediately. DO NOT ATTEMPT TO REPAIR POWER CORD.

IMPORTANT SAFETY INSTRUCTIONS

WARNING: When using electric tools, basic safety precautions should always

be followed to reduce the risk of fire, electric shock and personal injury, including the following:

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.

READ AND FOLLOW ALL INSTRUCTIONS.

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 PorterCable and we have advised you.

ADDITIONAL SAFETY RULES FOR CIRCULAR SAWS

1. KEEP GUARDS IN PLACE AND IN WORKING ORDER. Never wedge or

tie lower guard open. Check operation of lower guard before each use. Do not use if lower guarddoes not close briskly over saw blade. CAUTION: If saw is dropped, lower guard may be bent, restricting full return.

2. KEEP BLADES CLEAN AND SHARP. Sharp blades minimize stalling and kickback.

3. DANGER: KEEP HANDS AWAY FROM CUTTING AREA. Keep hands away from blades. Do not reach underneath work while blade is rotating. Do not attempt to remove cut material when blade is moving. CAUTION: Blades coast after turned off.

900315 - 10-31-00.qxd 2/25/02 9:45 AM Page 4

4. SUPPORT LARGE PANELS. Large panels must be supported, as shown

in Fig. 10, to minimize the risk of blade pinching and kickback. When cutting operation requires the resting of the saw on the workpiece, the saw shall be rested on the larger portion and the smaller portion cut off.

5. USE RIP FENCE. Always use a fence or straight edge guide when ripping.

6. GUARD AGAINST KICKBACK. Kickback occurs when the blade is pinched and the saw is driven back towards the operator. Keep body to side of blade. Stay alert and maintain firm grip on saw for control. Release switch immediately if blade binds or saw stalls. Keep blades sharp. Support panels as shown in Fig. 10. Use fence or straight edge guide when ripping. DO NOT force tool. DO NOT remove saw from work during a cut while blade is moving.

7. LOWER GUARD. Raise lower guard with the retracting handle when pocket cutting.

8. ADJUSTMENTS. Before cutting be sure depth and bevel adjustments are tight.

9. USE ONLY CORRECT BLADES IN MOUNTING. Do not use blades with incorrect size holes. Never use defective or incorrect blades, washers or bolts.

10. AVOlD CUTTlNG NAlLS AND KNOTS. Inspect for and remove all nails from lumber before cutting. Try to layout cuts between knots.

11. 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.

REPLACEMENT PARTS

When servicing use only identical replacement parts.

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 andpossible 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 following the cord type designation. For example – SJTW-A to indicate it is acceptable for outdoor use.

OPERATING INSTRUCTIONS

FOREWORD

Your Porter-Cable Trim Saw is designed for cutting trim, composition board, plywood, plastics, plexiglas and other problem materials. Maximum depth of cut is 1

/16

" at 90° and 1

/16

" at 45° with 4

" diameter blade.

SELECTING THE BLADE

A Combination Blade is furnished with your saw and is an excellent blade for all general ripping and crosscutting operations. When crosscutting and smoothness of cut is an important factor, a thin rim blade is recommended. Also, a fine tooth blade should be used when cutting plywood and masonite. Special blades are available for cutting plexiglas and “problem materials” such as metal laminates and gauge size sheet steel. Recommended blades for use with your saw are listed under ACCESSORIES in the back of this manual.

TO CHANGE SAW BLADES

CAUTION: DISCONNECT SAW FROM POWER SOURCE.

To remove the blade, place the teeth of the blade against the edge of a board and loosen the blade retaining screw by turning it counterclockwise with wrench provided. Remove blade retaining screw and outer flange washer. Hold telescoping guard open and remove blade. Before installing a new blade, remove inner flange washer and wipe it clean. Also remove any sawdust that may have accumulated within the guards, around the saw arbor, and from the telescoping guard spring. Check the telescoping guard to insure it is in working order.

CAUTION: If telescoping guard movement is sluggish or binding exists, return the saw to your nearest AUTHORIZED PORTER-CABLE SERVICE STATION or PORTER-CABLE SERVICE CENTER for repair. NEVER use your saw if the telescoping guard is not in working order.

Install the inner flange washer and place the new blade on the arbor making sure the teeth point UP at the front of the saw, (EXCEPT for the special blade for cutting plexiglas – see below).

Clean and replace the outer flange washer making certain the square hole mates with the squared end of the saw arbor. Install and firmly tighten the blade retaining screw.
