SAWINSTALLATION
Positioning thesawona level surface ( shimming may be
required) willimprove stability a ndaccuracy andprevent
warpage and failure ofcast c omponents andwelds. Level the
sawusing s hims ormachine mounts. The stationary saw's
base isfitted with fourmounting holes. Theholes arelocated
within anorange r ecess. Use these holes tosecure s tationary
saw tothefloor. This saw should bepermanently fastened to
thefloor. This willdecrease vibration andincrease stability.
DANGER: The drive pulley a ndmotor pulley f urnished, will
runtheblade atapproximately 4000 RPM when used with
3500 RPM motor. Never substitute these pulleys toincrease
this speed b ecause itcould bedangerous.
ARBOR EXTENSION INSTALLATION
Refer to Figure 9, page 20.
° Wipe clean taper and threads of arbor extension (No. 36).
It is recommended when installing that a dry lubricant be
used on taper end of arbor extension.
• Install arbor extension (No. 36) into arbor (No. 35).
Standard arbor extension for 12" saw (228031) is 1" O.D.
x 3" long. By hand, thread arbor extension by inserting
8mm hex wrench (not shown) into 8mm socket at outboard
end of extension and tighten. Arbor itself is held in place
with spanner wrench (No. 39). Place spanner wrench on
inside blade flange with two prongs on spanner wrench
inserted into two holes in flange. Seat arbor extension
firmly. However, it is not necessary to excessively tighten.
NOTE: To remove an arbor extension, follow the preceding
steps in reverse order.
BLADE INSTALLATION
Refer to Figure 9, page 20.
NOTE: 228031 is supplied with a 12" x 1" 40T blade. 228051
is supplied with a 10" x %" 40T blade.
WARNING: Turn the power switch OFF and unplug the power
cord from its power source when changing the saw blade.
WARNING: When replacing blades, check the thickness
stamped onto the riving knife. You must select a blade with
a kerr width larger than the thickness of the riving knife. The
kerr width should be marked on the blade or blade package.
Thinner blades may cause the workpiece to bind during cutting.
228051 -2.5mm thick riving knife. Only use for 10" diameter
blade with 3.0mm min. kerf width and 2.0mm max. body
thickness.
228031 -2.5mm thick riving knife. Only use for 12" diameter
blade with 3.0mm min. kerf width and 2.0mm max. body
thickness.
• Remove arbor nut and blade flange (Nos. 37 and 38)
from the arbor.
• Check that arbor diameter matches mounting hole of
blade. 12" saw, 228031, is supplied with a 1" standard
arbor extension. 10" saw, 228051, is supplied with a 5/8"
standard arbor extension. If necessary, remove incorrect
arbor extension using spanner wrench (No. 39) and hex
wrench supplied.
• Mount required arbor extension to arbor; be sure that
arbor and arbor extension are clean and free of dirt,
chips, etc. Tighten arbor extension securely in arbor.
• Mount blade onto the arbor extension. Be sure blade is
mounted so that it spins in proper direction. Replace
arbor flange and nut. Tighten nut securely.
IMPORTANT: Blade rotates towards front of saw. When
installing blade, make sure teeth are pointing towards front
of the saw.
NOTE: Do not over tighten arbor nut. Use the arbor wrench
to just "snug" it.
ASSEMBLE HANDWHEELS
Refer to Figures 10 and 11, pages 22 and 24.
• Both handwheels are identical. Attach crank handles
(Fig. 11, No. 13) securely to handwheels (Fig. 11, No. 27).
• Handwheels are attached to tilt adjustment shaft (Fig. 10,
No. 4) and height adjustment shaft (Fig. 10, No. 24).
• Place key (Fig. 10, No. 6) in keyway. Assemble handwheel
to shaft engaging set screw (Fig. 11, No. 28) with key in
shaft. Position handwheel onto shaft as far as possible
without interfering with movement. Tighten set screw.
• Install locking knobs (Fig. 11, No. 23). Insert threaded por-
tion of knobs into end of shafts. Gently hand tighten until
it stops. This is locked position. To unlock, back out knob
three complete turns. For now, leave handwheels unlocked.
NOTE: Do not over tighten locking knobs.
CHECK TABLE ALIGNMENT
Refer to Figures 3 and 11, pages 6 and 24.
• Saws are shipped from the factory with the table adjusted
so the miter gauge slots are parallel to the saw blade.
However, in order to obtain the best results from the saw, it
is suggested this adjustment be checked before operating.
• A simple method of checking alignment is as follows: Bolt
or clamp a dowel rod or similar object to miter gauge (a
combination square can be substituted).Pick out a tooth
on front of blade and set the dowel to it so it is just touch-
ing. Move same tooth to back of blade.
• Gauge this tooth with the dowel rod. If the tooth is in the
same position, relative to the miter gauge, the table is par-
allel with the blade. In short, the miter gauge slots must be
parallel with the blade. This means that when measuring
distance between blade and slot at the front and rear of the
blade, the distances will be equal (see Figure 3, page 7).
