HC-450/HC-300 Hole Cutting Tools

Maintenance Instructions

WARNING
Make sure that the ON/OFF switch is in the OFF po-
sition and the tool is unplugged before performing
any maintenance or making any adjustments.
Maintain tool according to these procedures to re-
duce the risk of injury from electrical shock, entan-
glement 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 dam-
age the bearings.
As needed, the chain and screw assemblies can be lu-
bricated with a light lubricating oil. Wipe any excess oil
from exposed surfaces.
