Caution
Please read these instructions carefully before using your electric rotary cutter. Unplug the power cable from the power source
before you perform any adjustment or maintenance on the cutter. Unplug the power cable when the cutter is not in use. You
should handle your cutter with extreme caution because of the sharp blade. When using, make sure the cord is always behind
the cutter.
Specification
Voltage:
110 V or 220 V
Power: 100 W
Max. Cutting Thickness: 1”
Weight: 6 Ib
Operation (See Figure 1)
Adjust the blade front guard to “just above the fabric” to help prevent
1.
cutting a finger or the cord.
Plug power cord into an electric outlet (110V or 220V depending on style
2.
of cutter).
Sharpen the blade by turning the switch on and pushing the grinding
3.
wheel push button as shown in Figure 2 with constant pressure for 10
seconds. The pressure should be large enough to keep the grinding wheel
in continuous contact with the blade to obtain a sharp and uniform cutting
edge. Try a piece of scrap fabric to clean the blade. Repeat this operation
if the blade is not sharp enough.
Your cutter is now ready to cut. Always start the cutter before contacting
4.
the fabric. Hold the cutter securely as you push the cutter steadily forward
along your cutting path.
You should practice on a piece of scrap before
using your cutter for the first time.
Lubrication and Maintenance
Put a drop of machine oil in the hole on the oil-ear (see Figure 1) once
1.
a day if you use the cutter every day. Otherwise put a drop of oil in the
hole on the oil-ear before every use of the cutter.
Unthread the grease feed cap off and inject a small amount of grease into
2.
the grease feed cup after every 50 hours use (see Figure 2).
Clean and brush off any dust or dirt on the backside of the blade and
3.
blade seat by removing the blade after every 50 hours use or whenever
you see a dirt built-up.

Blade Replacement
Replace the blade with a new one,
Stk#DT47/A
, when the diameter of the blade becomes too small to meet the lower blade
properly. The cutter comes with an additional 4” octagon blade. You can use an optional 4” round blade, Stk#DT47/H,
which is better for cutting thin or delicate fabric. Blades are sharp, use caution when handling.
Unplug the power cord.
1.
Remove the blade front guard by pulling it upward, and turn the oil-ear outward as shown in Figure 1.
2.
Remove the blade rear guard by loosening its thumb screw (see Figure 1).
