The green colored rigid ear, lug or tab,
extending from the adapter must be connected
to a permanent ground such as a properly
grounded outlet box, as shown in Figure 5.
Extension cords
If an extension cord is necessary, make sure the
cord rating is suitable for the amperage listed on
the machine’s motor plate. An undersized cord
will cause a drop in line voltage resulting in loss
of power and overheating.
Use the chart in Figure 6 as a general guide in
choosing the correct size cord. If in doubt, use
the next heavier gauge. The smaller the gauge
number, the heavier the cord.
Adjustments
Stock Stop
The stock stop is useful for making multiple cuts
of the same length. Simply determine the stock
stop’s position, then place the end of successive
workpieces against the stock stop. See Figure 7.
Loosen the knob and slide the stock stop to the
desired place on the rod. The stock stop can be
installed on the rod in reverse position, for
cutting longer workpieces. Always tighten the
knob before operating.
Blade Guide and Bearings
1. Disconnect machine from power source.
2. The front bearing (B, Figure 8) is mounted
to an eccentric bushing and is adjustable.
Loosen the cap nut (A, Figure 8) and rotate
the front bearing (B, Figure 8) until the
bearing just lightly contacts the blade. Do
not pinch the blade.
3. Re-tighten cap nut (A, Figure 8).
4. Repeat for the other guide bearing
assembly.
5. There should be minimal exposure of the
blade during cutting operations. Loosen the
handle (C, Figure 8) and slide the blade
guide assembly (D, Figure 8) as close to the
workpiece as possible without interfering
with the workpiece.
6. Re-tighten handle.
