12.1 Replacing Tires
The rubber tires that cover the drive wheels
protect the wheel from blade damage and
provide a high friction drive force on the
tensioned blade. Over a long period of service,
the tires wear and may require replacement.
1. Disconnect machine from power source.
2. Remove the blade according to the
instructions on page 14.
3. Use a flat screwdriver blade or knife blade to
loosen the tires and remove them from the
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
tires.
5. Carefully slip the replacement tires onto the
drive wheels.
6. Re-install the saw blade and re-connect the
saw to power.
