Porter-Cable 7312 Laminate Trimmer User Manual


 
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.

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.
