MAINTENANCE
Lubrication
The motor bearings are lubricated and sealed at the
factory. Merely leave them alone unless they need to be
replaced.
The upper and lower arms have two bushings each that
require lubrication after every 8 hours of machine use.
To lubricate the arm bushings, do these steps:
1. DISCONNECT MACHINE FROM POWER!
2. Remove the plastic caps over the bushings to expose
their ends (see Figure 16).
3. Lay the saw on its side as flat as possible, then apply
a generous amount of light machine oil to the two
cups around the bushing ends. Let the oil seep into
the bushings for an hour or two.
4. Wipe off the excess oil, turn the saw over, and
repeat Step 3 to the remaining two bushings.
5. Replace the plastic caps before beginning operation
to keep dust and debris from reaching the bushings.

the arm bushing ends.

Motor Brushes
Over time the motor brushes will wear. Periodically,
remove and examine them. Replace them if they are
damaged, severely blackened with carbon build-up, or less
than
1

To inspect/replace the motor brushes, do these steps:
1. DISCONNECT MACHINE FROM POWER!
2. Remove the plastic caps securing the motor brushes
(see Figure 17). The top cap is accessible from the
top of the motor, and the bottom cap is accessible
through a hole on the bottom of the base.
3. Pull the brush assemblies from the holes and inspect
them for damage or wear. Replace them if necessary.
4. After replacing the brush assemblies, secure them
with the plastic caps.
