ADDITIONAL SAFETY RULES FOR COMPOUND MITER SAWS

1. WARNING: USE ONLY CROSS-CUTTING SAW BLADES. DO NOT USE BLADES WITH DEEP GULLETS AS THEY CAN DEFLECT AND CONTACT THE GUARD.

2. WARNING: Do not operate the miter saw until it is completely assembled and installed according to the instructions.

3. IF YOU ARE NOT thoroughly familiar with the operation of compound miter saws, obtain advice from your

supervisor, instructor or other qualified person.

4. BE SURE blade is sharp, runs freely and is free of vibration.

5. ALLOW the motor to come up to full speed before starting cut.

6. KEEP motor air slots clean and free of chips.

7. ALWAYS MAKE SURE rotating table is tight before cutting, even if the table is positioned in one of the positive

stops.

8. BE SURE blade and flanges are clean and that arbor screw is tightened securely.

9. USE ONLY blade flanges specified for your saw.

10. NEVER apply lubricants to the blade when it is running.

11. ALWAYS CHECK the blade for cracks or damage before operation. Replace cracked or damaged blade

immediately.

12. ALWAYS KEEP the lower blade guard in place and operating properly.

13. MAKE SURE blade is not contacting workpiece before switch is turned on.

14. NEVER LOCK the switch in the “ON” position.

15. IMPORTANT: After completing cut, release power switch and wait for coasting blade to stop before returning

saw to raised position.

16. DO NOT remove jammed or cut-off pieces until blade has stopped.

17. NEVER cut ferrous metals or masonry.

18. NEVER recut small pieces.

19. PROVIDE ADEQUATE SUPPORT to the sides of the saw table for long workpieces.

20. NEVER use the miter saw in an area with flammable liquids or gases.

30. KEEP CLEAR OF SAWDUST EJECTION CHUTE. Sawdust and chips are expelled out the ejection chute at

rear of saw. Do not allow anyone in this area while saw is in operation.

31. WHEN THE MITER SAW IS NOT IN USE, the switch should be locked in the OFF position to prevent unauthorized use of the saw.

REPLACEMENT PARTS

When servicing, use only identical replacement parts.

POLARIZED PLUGS: To reduce the risk of electric shock, this equipment has 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 the proper outlet. Do not change the plug in any way.

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 of 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 where the voltage is not within correct limits. Do not operate tools rated A.C. on a D.C. current. To do so may seriously damage the tool.

EXTENSION CORD SELECTION

OPERATING INSTRUCTIONS

FOREWORD

Porter-Cable Model 3802 Type 2 is a high capacity 12" compound miter saw designed to cut wood and nonferrous metals. It can crosscut 8" x 2¼" and 7" x 3¼", miter at 45 both left and right 5¼" x 2¼", bevel at 45 left 6¼" x 2¼" and 8" x 1¼", and compound 45 x 45, 5¼" x 2 1/2" and 4¼" x 2¼". It has positive miter stops at 0, 15, 22.5, 31.62, and 45 degrees both left and right, and bevel stops at 0 and 45 degrees left.

POWER CONNECTIONS

A separate electrical circuit should be used for your tools. 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. For distances up to 100 feet, use #12 wire. For distances up to 150 feet, use #10 wire. 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 indicates that it is acceptable for outdoor use. Replace damaged or worn cords immediately. Before connecting the motor to the power line, make sure the switch is in the “OFF” position and be sure that the electric current is of the same characteristics as stamped on motor nameplate.

GREATER THAN 50 FEET NOT RECOMMENDED

Use proper extension cords. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current of the saw. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. 1, shows the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
