Maintenance Instructions
Warning: Make sure that the ON/OFF switch is in the OFF position and the tool is
unplugged before performing any maintenance or making any adjustments. Maintain
tool according to these procedures to reduce the risk of injury from electrical shock,
entanglement and other causes.
Cleaning
After each use, wipe any chips or oil off with a soft, clean, damp cloth, especially areas of
relative motion such as the posts. Clean any dust and debris from the motor vents.
Lubrication
The Hole Cutting Tools gearboxes are designed as sealed systems, and should not require
any additional grease unless significant leakage has occurred. In those cases, the tools
should be returned to a service center. Do not lubricate the bearings that ride on the posts.
The bearings are not designed to be used with lubricants, and lubricants will hold dirt and
debris that could damage the bearings. As needed, the chain and screw assemblies can be
lubricated with a light lubricating oil. Wipe any excess oil from exposed surfaces.
Machine Storage
The Hole Cutting Tool must be kept indoors or well covered in rainy weather. Store the
machine in a locked area that is out of reach of children and people unfamiliar with hole
cutting tool. This machine can cause serious injury in the hands of untrained users.
