Porter-Cable 7310 Functional Description, Extension Cord Selection, Foreword, Selecting The Bit

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 the flush and bevel trimming of laminated plastics, phenolics, and other similar materials that have a bonding agent too hard to be trimmed with ordinary tools.

The Tilt-Base model allows trimming into corners inaccessible to standard trimmers. This model also allows the trimming of 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 for trimming narrow ledges.

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" diameter shanks. Bits are available as an accessory.
