7. Remove the blade from both wheels and out of each
blade guide. CAUTION: Even dull blades are sharp
to the skin. Wear leather gloves when handling
blades.
8. Clean the swarf out of the blade wheel area.
9. Make sure the teeth of the new blade are pointing
in the direction of travel. If necessary, turn the blade
inside out.
10. Position the blade on the wheels and beneath the
urethane block (C, Fig. 13-1). Make sure back of the
blade rests lightly against wheel fl anges.
MAKE SURE THAT BACK OF BLADE IS AGAINST
THE WHEEL FLANGES OF BOTH WHEELS. THIS
IS VERY IMPORTANT.
11. Twist the blade and slip it into the blade guides with
the back of the blade against the back-up bearing (see
Fig. 13-3).
NOTE: If roller bearings need adjusting
refer to sect. 13.4.
12. When you are sure the back of the blade is against the
wheel fl anges of both wheels and properly inserted
into the guides, reconnect power to the saw and
release E-stop..
13. Turn lever (D, Fig. 13-8) to tension blade.
14. Reposition chip brush so that it contacts the blade,
and tighten in place.
15. Jog the blade “on” and “off ” to be sure the blade is in
place and tracking properly.
16. If blade is not tracking properly refer to sect. 13.11.
Otherwise blade installation is done.
17. Close all covers, replace all guards, and fasten
securely.
18. Follow blade break-in procedures, sect. 13.2.
13.2 BLADE BREAK-IN
A new blade should be “broken in” before normal,
extended use. Failure to break in a new blade will shorten
the service life of the blade, and result in ineffi cient cutting
performance.
1. Reduce blade speed to 1/2 of normal setting.
2. Set feed rate at 2 to 3 times longer than normal.
3. Make 5 complete cuts at the above settings, through
an 8-inch (200mm) diameter workpiece. Listen for
unusual noises or metallic sounds.
4. If no unusual sounds or other issues are detected,
then the blade is ready for normal operations.
13.3 ADJUSTING BLADE GUIDE POST
The blade guides should be set as close to the vise jaw as
possible. The right blade guide bracket is not adjustable
and is set at the factory to clear the right hand vise jaw.
The left blade guide post can be moved left or right
depending on the position of the sliding vise jaw.
To move the left blade guide post, loosen handle (R,
Fig. 13-2), slide post into position as close to workpiece
as possible without causing obstruction, then retighten
handle.
The accompanying scale measures distance of exposed
blade between the blade guides.
