DEPTH ADJUSTMENT KNOB

A spring loaded depth adjustment knob makes it possible to
make proper settings for three standard size biscuits. Fine
adjustments to the cutting depth can be made with a knurled
adjustment knob and jam nut located behind the depth
adjustment knob. Once the correct depth setting has been
made for one biscuit size, the other two depth settings will be
automatically set.

DUSTLESS FEATURE

The dust bag provides a dust collection system. Wood
particles are drawn up through a tunnel in the base and
collect in the dust bag during cutting operations.

INDICATOR MARKS

Centerline and line of cut indicator marks have been provided
on your plate joiner. 

See Figure 2.

FEATURES

Your Plate Joiner has been designed for making fast, accurate,
and simple plunge cuts in wood, etc. so that biscuits can be
used to join two or more boards together. When used
properly and only for what it is intended, this versatile tool will
give you years of trouble-free performance.  It is professionally
engineered, but its ease of operation allows the amateur to
produce work that is beautiful and precise.

SWITCH

To turn your plate joiner 

ON

, depress the switch trigger.

Release switch trigger to turn your plate joiner 

OFF

.

MOTOR

Your plate joiner has a powerful motor with sufficient power
to handle tough cutting jobs. It develops a no load speed of
10,000 RPM.

CARBIDE TIPPED BLADE

Your plate joiner has an 8-tooth carbide-tipped blade for
cutting biscuit slots.

NON-SKID BACKING PAD

The fence on your plate joiner is padded with a non-skid
backing pad to hold it stationary against the workpiece. It
helps prevent skidding when making cuts. It also prevents
marring of the workpiece from your plate joiner when making
cuts.

APPLICATIONS

(Use only for the purpose listed below)

Cutting precise mating oval slots in hard wood, soft wood,

plywood, particle board, etc., for spline joinery applications.

ELECTRICAL CONNECTION

Your tool has a precision built electric motor. 

It should be

connected to a power supply that is 120 volts, 60 HZ, AC

only (normal household current.)

  A substantial voltage

drop will cause a loss of power and overheating. If your tool
does not operate when plugged into an outlet, double-check
the power supply.

BISCUITS

See Figure 1.

Biscuits are available in three standard sizes:

#0 (5/8 in. x 1-13/16 in.)

#10 (13/16 in. x 2-1/16 in.)

#20 (15/16 in. x 2-5/16 in.)

NOTE: 

 Biscuits swell rapidly upon contact with water-based

woodworking glues.

ADJUSTABLE FENCE / FRONT HANDLE

Your plate joiner has an adjustable fence. By loosening the
height adjustment knobs, the angle of the fence can be set
at angles from 0

°

  to 135

°

, with positive stop settings in

increments of 45

°

. The height of the fence can be set

between 0 in. - 2 in. with a scale showing 0 in. - 1-1/2 in.

The front handle is part of the adjustable fence and should
always be used to guide and balance your plate joiner,
providing ease of operation and maintaining safe control.
