WaRninG
Always operate a tool at the speed range set by the manufacturer.
Failure to do so may result in serious injury or machine damage.
To change the speed and adjust to proper belt tension:
1. Disconnect the machine from its power source.
2. Open the access door. NOTE: A limit switch is provided which
prevents the machine from being turned on when the access
door is open.
3. The belt can be moved to the desired steps of the motor pulley
and spindle pulley. To loosen belt tension, move the belt tension
lever to the right. At the same time, rotate the knob to slide the
speed bar up or down so that the belt will be positioned in the
cut-out in speed bar.
4. After the belt is positioned as desired, move the tension lever to
the left to apply tension to the belt.
5. Close and latch the access door.
Note: After a short time, the belt may stretch. Check tension by
pressing the center of the belt with a force of 6.6 lbs (3 kg.) Tension
is correct when

" (5mm) of defection is observed. Turn the two
nuts to adjust best belt tension.
Never place the V-belt under excessive strain, as this can overload
the motor and damage the bearings, spindle or belt.
8.2 Spindle Height Adjustment
Adjust spindle height to achieve the desired cut. The spindle height
can be precisely measured using the digital readout feature.
1. Loosen handwheel lock and spindle locking lever.
2. To raise the spindle, turn handwheel counterclockwise and to
lower the spindle, turn handwheel clockwise.
3. Note: One complete turn of the handwheel moves the spindle
up or down by 1mm or 2.5 mm indicated on the machine frame
(sticker).
4. Tighten handwheel lock and spindle locking lever when desired
spindle height is obtained.
8.3 Using Fence(s)
WaRninG
Keep guards in place and in working order. Always use the fence
assembly when work permits.
Using the fence is the safest and most accurate method of shaping,
and should always be used when work permits. The majority of
straight work can be performed using the fence.
For normal work, where a portion of the original edge of the stock is
not touched by the cutter, both the infeed and outfeed fences are in
a straight line.
When the shaping operation removes the entire edge of the
workpiece, e.g. in jointing or making a full bull nose, the shaped
edge will not be supported by the outfeed fence edge when both
fences are in line. In this case, the workpiece should be advanced
to the position shown and stopped. The outfeed fence should then
be moved forward to make contact with the workpiece. The outfeed
fence will then be in line with the cutting circle, and the operation
can continue.

Note: All Ironwood shapers accommodate Stiles power feeders.
Power ports are included on the rear of the machines. For more
information review operators instructions included with the power
feeder or contact Stiles machinery.
8.4 Adjusting Fence Extensions
WaRninG
To eliminate gaps between the edges of the fence and cutter, both
fences should be adjusted as close to the cutter spindle tooling
as possible.
For added safety, the fence extensions can be adjusted to the
height of the cutterhead so that you expose only the amount of tool
required to make a safe cut is exposed.
Using an Allen wrench, loosen the aluminum fence extensions, slide
them horizontally into desired position, and tighten.
