CHANGING THE SAW BLADE (CONT.)
9. Carefully wrap the blade around the bottom wheel
(Fig. 29 - 2). Hold the blade around the bottom wheel
with one hand and slip it around the top wheel with the
other hand, keeping the blade between the blade guide
bearings. The blade should be positioned next to but
not tightly against the wheel flange.
10. Turn the blade tension knob (Fig. 28 - 1) clockwise
to tension the blade just enough so that the blade will
NOT slip on the wheels upon startup. Do not over ten-
sion the blade.
11. Close the blade cover door and secure with the
cover washers and screws. Re-tighten drive wheel cover
screws (Fig. 27 - 1).
12. Reattach the red blade guard (Fig. 25 - 1) and wire
brush assembly (Fig. 26 - 1).
13. Refer to the next section “Adjusting the Blade Ten-
sion” for setting the blade tension for your new blade.
MAINTENANCE
ADJUSTING THE BLADE TENSION
Correct blade tension is important for proper operation
of the saw. To set the blade tension for a new blade:
1. After a new blade has been installed, ensure that the
blade has been roughly tensioned according to step 10
above and does not slip on the wheels. Make sure all
covers are closed and all guards are in place.
2. Connect the machine to the power source. Run

Fig. 30
the saw for 2 to 3 minutes to allow the blade to seat
properly on the wheels. Turn OFF and disconnect the
machine from the power.
3. Refer to the blade tension gauge (Fig. 30) for proper
tension of the blade. Adjust the blade tension using the
blade tension knob on the left of the saw (Fig. 28 - 1).
Turn the blade tension knob clockwise to add tension;
turn the knob counterclockwise to reduce tension, until
the blade tension gauge arrow points to the green box
(Fig. 30 - 1) on the center of the gauge.
CAUTION:
Do not over tighten the blade. Over-
tightening will cause the blade to stretch and warp
