4.- Operating Speeds
To select the right speed for each job, use a practice
piece of material.
NOTE: Speed is affected by voltage changes. A
reduced incoming voltage will slow the RPM of the tool.
On the two-speed model, there is a LO and HI switch. When
the switch indicator is on the low setting, the tool runs at
about 8.000 RPM. When the switch indicator is on the high
setting, the tool runs at about 33.000 RPM.
The speed of Rotary Tool is controlled by setting this
indicator on the housing.
Needs for Slower Speeds
Certain materials, however, (some plastics and precious
metals, for ex ample) require a relatively slow speed
because at high speed the friction of the accessory
generates heat and may cause damage to the material.
Slow speeds (8.000 RPM) usually are best for polishing
operations employing the felt polishing ac ces sories. They
may also be best for working on deli cate projects as
“eggery” work, delicate wood carving and fragile model
parts. (All brushing applications require lower speeds to
avoid wire discharge from the holder.)
Higher speeds are better for carving, cutting, routing,
shaping, cutting dadoes or rabbets in wood.
Hardwoods, metals and glass require high speed
operation, and drilling should also be done at high speeds.
Ultimately, the best way to determine the correct speed for
work on any material is to practice for a few minutes on a
piece of scrap, even after referring to the chart. You can
quickly learn that a slower or faster speed is more effective
just by observing what hap pens as you make a pass or two
at different speeds. When working with plastic, for example,
start at a slow rate of speed and increase the speed until
you observe that the plastic is melting at the point of
contact. Then reduce the speed slight ly 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 8.000 RPM
to prevent damage to the brush.
3. Wood should be cut at high speed.
4. Iron or steel should be cut at low speed.
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 lubricant
on the cutter to prevent the cut material from adhering to the
cutter teeth.
Increasing the pressure on the tool is not the answer when it
is not performing as you think it should. Perhaps you should
be using a different accessory, and perhaps an adjustment
in speed would solve the problem. Leaning on the tool does
not help.
Let speed do the work!
5.- Maintenance Information
Service
Preventive maintenance pe r formed by
unauthorized per so n nel may result in
misplacing of internal wires and components which
could cause serious hazard. We recommend that all tool
service be performed by a STAYER authorized service
.
To avoid injury from unexpected starting
or electrical shock, always remove plug
from wall outlet before performing service or cleaning.
