Kawasaki 840169 Power Hammer User Manual


 
This rotary tool is a multipurpose power tool. It is a drill, polisher, power brush,
grinder, cutter, and sander all in one. This high-speed, low torque tool is easy to
handle and accepts a wide range of accessories from polishers to router bits to wire
brushes and grinding wheels. The high speed allows it to do jobs that low speed
tools can't handle like engraving glass or cutting hardened steel.
Hold the tool in your hand and find your best grip.
Never push on the tool. The high speed and the accessory, not the pressure on the
tool, do the work.
Practice by making passes on a scrap piece of material. This tool works best if you
do the work in small increments, moving back and forth until you reach the desired
result.
OPERATING SPEEDS
Speed is affected by voltage changes. If the incoming volt-
age is reduced, it will slow the RPM of the tool, especially at the lowest setting.
If the tool appears to be running slowly, increase the setting accordingly.
The operating speed will vary depending on the material and type of accessory you
are using.
To find the right speed for your job, use a test piece of the material. Try various
speeds until you find the one that is best for your project.
If you are doing delicate woodcarving, polishing, buffing or any use which requires
a wire brush, slow speeds of 15,000 RPM or less are best. Any material, like plas-
tic, that melts at low temperatures should also be cut at low speeds.
If you are carving, routing, shaping or cutting glass, metal or hardwoods, higher
speeds are necessary. Drilling should also be done at high speed.
Softer metals, like aluminium, copper alloys, and tin may be cut at various speeds,
depending on the type of cutting being done. A lubricant like wax should be used on
the cutter to keep the cut material from adhering to the cutter teeth.
If the tool is not performing the way you think it should, perhaps you are using the
wrong accessory. Putting pressure on the tool will not help the performance.

OPERATING INSTRUCTIONS
Disconnect the power plug from the AC power source
before any assembly, adjustments, or adding/removing accessories.
Following this preventative step reduces the risk of the saw coming on acciden-
tally and the risk of damage to the workpiece and injury to the operator.
Never hold the tool near your face. Accessories like wire brushes or grinding
wheels may come apart during use.
Be careful not to cover the air vents with your hand. This
will cause the motor to overheat.
