greater.
1. Follow all "Moving Guard Assembly" and "Remov-
ing Blade" steps.
2. Carefully handle the new blade. Check that the
rotation arrow on the blade matches the rotation
arrow on the lower guard. Slide the blade up and
between the sides of the chip deflector and over
the arbor shaft. Move the blade so its arbor hole
goes around the support ring of the inner washer
(see Figures 4 and 5).
3. Place the outer washer over the arbor shaft and
finger-tighten the blade bolt (counterclockwise).
Check that the blade remained on the inner
washer's support ring.
4. Rotate the blade slowly while pressing the arbor
lock until it fully seats into its lock position.
5. Using the 6/4mm hex key, firmly tighten the blade
bolt counterclockwise. NOTE: This bolt has left-
hand threads. Do not over tighten. A 6mm hex key
may be used as an alternate.
6. Remove the lower guard link from the rear cover
plate screw. Rotate the lower guard and cover
plate around the front cover plate screw until the
cover plate's slot slides under the rear cover plate
screw head. Fully tighten both cover plate screws
using the 6/4mm hex key.
7. Place the lower guard link back to the original po-
sition, then firmly finger-tighten the link knob to the
pivot post. It may be necessary to retract the lower
guard while tightening the link knob.
8. Be sure the arbor lock is released so the blade
turns freely.
9. Place the 6/4mm hex key back in storage area.
