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

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.

OPERATING INSTRUCTIONS

FOREWORD

Porter-Cable Model 3802 Type 2 is a high capacity 12" compound miter saw designed to cut wood and non- ferrous 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.
