OPERATION
NOTE: ILLUSTRATIONS START ON PAGE 12
AFTER FRENCH AND SPANISH LANGUAGE SECTIONS.
Higher speeds are better for carving, cutting, and shaping
wood.
Hardwoods and glass require high speed operation. Drilling
should also be done at high speeds.
To determine the optimum operational speed for different
materials and accessories, refer to the
Application Speed
Recommendations
table. Look this table over and become
familiar with it.
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 table. You can quickly
learn that a slower or faster speed is more effective just by
observing what happens when you make a pass or two at
different speeds.
When working with a scrap piece of plastic, start at a slow
rate of speed and increase the speed until you observe
whether the plastic is melting at the point of contact; reduce
the speed slightly to get optimum working speed without
melting the workpiece.
Plastic and materials that could melt at low temperatures
should be cut at low speeds.
Soft wood should be cut at high speed.
OPERATING THE ROTARY TOOL
See Figures 9 - 10, page 13.
Learning to use the rotary tool:
Hold the pen in your hand and get used to its weight,
balance, and the taper of the housing. This taper permits
the tool to be grasped in a “pencil grip” method or in a
“golf grip” method.
Examine the rotary tool accessories carefully. Damaged
accessories can fly apart as they come up to speed and
should not be used. The use of damaged accessories
can result in serious personal injury.
Practice on scrap materials first to see how the tool
operates. Keep in mind that the work is done by the speed
of the tool and by the accessory in the collet. You should
not lean on or push the tool into the work.
It is best to make a series of passes with the tool rather than
attempt to do all the work in one pass. To make a cut, pass
the tool back and forth over the work like you would a small
paint brush. Cut a little material on each pass until you reach
the desired depth. For most work, a gentle touch is best;
you will have greater control, make fewer errors, and get the
most efficient work out of the accessory.
For the best control in close work, grip the tool like a pencil
between your thumb and forefinger.
A “golf grip” method of holding the tool is used for operations
such as grinding a flat surface.
To operate the rotary tool:
Secure all work in a vise or clamp to a workbench to
prevent it from moving under the tool.
Hold the tool in front and away from you, keeping the tool
accessory clear of the workpiece.
Turn on the tool and let the motor and accessory build
up to full speed.
Lower the tool gradually until the accessory contacts the
workpiece.
Move the tool continuously at a steady, consistent pace.
Use just enough pressure to keep the tool from chattering
or bouncing.
NOTE:
Heavy pressure will decrease the tool’s speed and
put a strain on the motor. The weight of the tool alone is
adequate for most jobs.
Lift the tool away from the workpiece before turning off
the tool.
MAINTENANCE
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
