SAFETY FIRST
Speed Reducer
Welcome to Hougen
Congratulations on your purchase of the Holcutter™ Speed
Reducer. Your Speed Reducer is designed to reduce RPMs
while maintaining torque when using large diameter Holcut-
ters™. The Speed reducer can be connected directly to a
drill in place of the chuck or held in the drill’s chuck. The 4:1
gear ratio allows a drill turning at 1000RPM to reduce the
cutter output to 250 RPM. This allows for a more correct
cutting RPM for the large diameter Holcutters. Through con-
stant innovation and development, Hougen is committed to
provide you with hole-producing tools and products to help
you be more productive.
Before attempting to operate your new Speed Reducer,
please read all instructions fi rst. These include the Oper-
ator’s Manual and Warning Label on the unit itself. With
proper use, care, and maintenance, your model will provide
you with years of effective holemaking performance. Once
again, thank you for selecting our product and welcome to
Hougen.
The Speed Reducer is capable of producing high torque:
•
Always keep a fi rm grip on both handles when
drilling.
• Do not overreach or overextend while drilling; it
is best to keep the tool close to your body.
• Work from a stable stance.
• Pay attention to your work.
• Always wear safety glasses and gloves.
• Do not use the Speed Reducer without the
Clamp Handle.
• Always use Slick-Stik™ lubricant when cutting.
