Replacing drive wheel rubber
protectors
The rubber rings that cover the drive wheels are
called protectors. The protectors protect the wheel
from blade damage and provide a high friction
drive force on the tensioned blade. Over a long
period of service, the protectors wear and may
require replacement.
WARNING: The saw must be turned off and
power disconnected any time the rubber
protectors are being changed.
1. Unplug the electrical cord or open the circuit
breaker in the branch circuit.
2. Remove the blade according to the step-by-
step instructions on blade replacement.
3. Remove the rubber protectors from the drive
wheels. Use a flat screwdriver blade or knife
blade to loosen the protectors, being careful
not to nick or score the aluminum drive
wheels.
4. Clean the surface of the drive wheels. Use a
solvent such as mineral spirits as required to
achieve a clean, dry surface for the new
protectors.
5. Carefully slip the replacement protectors onto
the drive wheels.
6. Replace the saw blade and return the saw to
service by following the steps in Changing
Saw Blades.
7. Plug the electrical cord into the power source or
close the circuit breaker on the branch circuit.
