10.4 Blade replacement
Disconnect machine from the
power source before changing saw blades.
Failure to comply may result in serious injury.
To change the saw blade ( Figure 10-3) :
1. Disconnect machine from power.
2. Clamp a piece of wood in the vise, and lower
the blade upon it to prevent rotation.
3. Release the linkage from the blade guard at
(A) with a 5mm hex key, and rotate the guard
out of the way.
4. Remove the screw (B) with a 10mm hex key.
NOTE: Left-hand threads; turn clockwise to
loosen.
5. Remove the blade (use gloves).
6. Secure a new blade by reversing the above
steps. Make sure the direction of the teeth is
correct.
IMPORTANT: A new blade requires a break-in
period. Use half the normal feed speed for the
operation; operate for a cutting surface of about
300 cm
2
for hard materials; about 1000 cm
2
for soft
materials. Then resume normal speed.

the cam lever at the handwheel to secure the
setting of the vise. NOTE: A long work piece
must have proper support on both ends.
2. If mitering, adjust the head accordingly and
lock it in position. If making a mitered cut,
verify that the blade will not contact the rear
vise jaw. If it will, loosen the screw on the rear
