MAINTENANCE, ADJUSTMENTS AND SERVICING
BLADE CLAMPING THUMBSCREWS - SET SCREWS
HANDLING
Never lift the saw by the upper arm assembly as this will
result in damage to the drivetrain.
Rather lift the saw by the front of the table and by the
motor.
Over time with normal use and wear, especially when
doing a lot of internal cutting where one end of the
blade is frequently disconnected then reconnected to
fit into a hole, the contact end of the thumbscrews
A
will
wear and can become smooth to the point were it will
no longer clamp the blade properly.
To avoid potentially costly downtime, consider keeping
a spare set of replacement thumbscrews and set screws
on hand for use if needed.
Note: If you begin to experience frequent blade slippage it may be a sign that it is time to replace the blade
clamp thumbscrew
B
and/or the set screws opposite the thumbscrews
C
.
Note: Overtightening to compensate for blade slippage may damage, or in extreme cases strip, the
threads in the blade clamping block.
Note: Before replacing either, always double check visually to make sure that the blade is being held
between the set screw and the thumbscrew as shown in
D
and is not being bent or kinked into the oppo-
site side of the blade clamping block because of a set screw that is adjusted too far back in the holder as
shown in
E

UPPER ARM TENSION ADJUSTMENT
Over time and with normal wear, the upper arm tension
will require adjustment to hold the arm in the raised posi-
tion. To adjust the upper arm tension:
1.
Loosen the lock nut
E
.
2.
Adjust the tension screw until the arm stays in
raised position.
3.
Re-tighten the lock nut.
