slightly to get the optimum working speed.
Some rules of thumb in regard to speed:
1.
Plastic and other materials that melt at low temperatures should be cut at low
speeds.
2.
Polishing, buffing and cleaning with any type of bristle brush must be done at
speeds not greater than 18,000 RPM to prevent damage to the brush.
3.
Wood should be cut at high speed.
4.
Iron or steel should be cut at high-speed. If a high speed steel cutter starts to
chatter — this normally means it is running too slow.
5.
Aluminum, copper alloys, lead alloys, zinc alloys and tin may be cut at various
speeds, depending on the type of cutting being done. Use paraffin or other
suitable lubricants on the cutter to prevent the cut material from adhering to the
cutter teeth.
STALL PROTECTION
This tool has a stall protection feature built into it to protect the motor and battery in
the event of a stall. If you stall the tool for too long, or bind the bit in a workpiece,
especially at high speeds, it will automatically turn itself off. Simply take the tool out
of the material you were stalled in, turn it off for 3 seconds, then turn it back on again
to continue using it. When the battery becomes close to empty, the tool may shut
down automatically more frequent than normal. If this happens, it is time to recharge
the battery.
Changing Collets
Using collets is the most precise way to hold an accessory in a high-speed rotary
tool. Even at high speeds and maximum pressure, collets stay tight. ( See Figure 5,
Figure 6)
-
Press and hold the spindle lock (A), and rotate the shaft with the provided collet
wrench (E) until the shaft lock (A) engages the shaft, preventing further rotation.
-
With the shaft lock (A) engaged, use the collet wrench (E) to loosen the collet nut
(D), if necessary.
-
Remove the collet nut (D) and old collet (C) using collet Wrench (E), if necessary.
-
Insert the un-slotted end of the collet (C) in the hole at the end of the tool shaft.
-
Tighten the collet nut with the collet wrench(E).
