Changing Blades - Wen 3962 Manual

CHANGING BLADES

WARNING: Blade teeth are sharp! Use care and
protective gloves when handling the saw blade. Failure
to comply may cause serious injury.
1. Confirm that machine is disconnected from power source.
2. Open both upper and lower doors.
3. Loosen rail guide lock knobs to remove the rail guide (Fig. J).
4. Remove rail guide.
5. Release tension on the blade by moving the tension knob (top
of case, Fig. K) counterclockwise.
6. Remove blade from upper and lower wheels and from between
the upper and lower blade guides.
7. Remove the blade through the slot in the table.
8. Guide the new blade through table slot leading with the smooth
edge. Place it around the upper and lower wheels and into the
upper and lower blade guides.
Note: The blade teeth should face the operator, and they should
point down towards the table.
9. Position the blade to track in the middle of the rubber tires on
the wheels.
10. Engage tension on the blade by moving the quick tension
knob clockwise.
11. Replace rail guide.
12. Before operating the saw, adjust blade tracking, blade tension,
and upper and lower blade guides.
ADJUSTING BLADE TENSION
WARNING: If the tension in the blade is too high, it runs the
risk of breaking. If the tension is too low, there is a risk of the
blade slipping and stopping during a cut.
1. Fully raise the upper blade guide.
2. Use the Blade Tension knob, located on the top of the upper case
(Fig. L) to adjust the blade tension, keeping in mind the width of the
blade.
3. When correctly adjusted, the blade should not deviate more than
one-tenth of one inch when pressed in with a finger.
4. Lower the upper blade guide.
Note: Turning the knob clockwise will increase blade tension, while
turning it counter-clockwise will decrease blade tension.
