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.

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.

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.
