Maintenance
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 customer service for
assistance. Use only identical replacement parts.
Any other parts may create a hazard.
5. Use liquid dishwashing detergent and water to
clean all plastic parts.
Note: Certain cleaning chemicals can damage
plastic parts.
6. Avoid use of cleaning chemicals or solvents,
ammonia and household detergents containing
ammonia.
Blade Raising and Tilting Mechanism
After every five hours of operation, the blade raising
mechanism and tilting mechanism should be checked
for looseness, binding, or any other abnormalities.
Referring Figure 43:
1. With the saw disconnected from the power
source, turn the saw upside down and pull up
and push down on the motor unit.
2. Observe any movement of the motor mounting
mechanism. Looseness or play in the blade raising
screw rod (A) should be limited to 1/8” or less.
3. If excessive looseness is observed in any other
parts of the blade raising mechanism or tilting
mechanism, take the complete unit to a Service
Center.
Place a small amount of dry lubricant on the bevel
gear (B). The screw rod (A) must be kept clean and
free of sawdust, gum, pitch, and other contaminants
for smooth operations.
Figure 43
If excessive looseness is observed in any part of the
blade raising mechanism or tilting mechanism, take
the complete unit to a Service Center.
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 is present, lubricate using
graphite or silicone. These dry lubricants will not
hold sawdust as would oil or grease.
Replacing the Carbon Brushes
Always disconnect the plug from
the power source before inspecting the brushes.
The carbon brushes included with the unit will last
approximately 50 hours of running time, or 10,000 ON/
OFF cycles. Replace both carbon brushes when either
has less than 1/4 in. length of carbon remaining, or if
the spring or wire is damaged or burned.
1. Remove the blade guard, blade, rip fence, miter
gauge and stand assembly from the table saw.
2. Place cardboard or an old blanket on the floor to
protect the saw table surface.
3. Place the saw upside down on the protective
material.
4. Tilt the blade elevation/tilting handwheel (A, Fig. 44)
to the 45° position.
