MAINTAINING YOUR TABLE SAW
GENERAL MAINTENANCE
For your own safety, turn the switch OFF and
remove the switch key. Remove the plug from
the power source outlet before maintaining or
lubricating your saw.
1. Clean out all sawdust that has accumulated inside
the saw cabinet and the motor.
2. Polish the saw table with an automotive wax to keep
it clean and to make it easier to slide the workpiece.
3. Clean cutting blades with pitch and gum remover.
4. A worn, cut, or damaged power cord should be
replaced immediately.
All electrical or mechanical repairs should be
attempted only by a trained repair technician.
Contact the nearest Porter-Cable Authorized Service
Center for service. Use only identical replacement
parts. Any other parts may create a hazard.
5. Use only mild soap and a damp cloth to clean
the tool. Never let any liquid get inside the tool;
never immerse any part of the tool into a liquid.
IMPORTANT: To assure product SAFETY and
RELIABILITY, repairs, maintenance and adjustment
(other than those listed in this manual) should be
performed by authorized service centers or other
qualified service organizations, always using identical
replacement parts.
NOTE: Certain cleaning chemicals can damage
plastic parts.
6. Avoid use of cleaning chemicals or solvents,
ammonia and household detergents containing
ammonia.
LUBRICATION
All motor bearings are permanently lubricated at the
factory and require no additional lubrication.
On all mechanical parts of your table saw where a pivot
or threaded rod are present, lubricate using graphite or
silicone. These dry lubricants will not hold sawdust as
would oil or grease.
