Proedge Blade Installation - Husqvarna 150D Operator's Manual

PROEDGE BLADE INSTALLATION

NOTE:
The 150D is shipped from the factory with the blade pre-
set to the proper cutting depth. Little or no adjustment is
necessary.
Step 1
With the saw turned off, fold the saw handle to its full upright
position and install the locking pin in the handle. With both
hands, push down on the handlebar and raise the saw to its
full height and locked position.
Step 2
Remove the blade block cover (A) by turning the two locking
knobs counter-clockwise. With the two wrenches supplied
with the saw, insert one in the slot at the front of the engine
and one on the bolt on the blade shaft in the blade block (B).
Rotate the blade shaft counter-clockwise with wrench on the
blade shaft bolt (C) until the second wrench engages the flats
on the other end of the shaft.
Step 3
Remove the blade shaft bolt by continuing to turn the bolt
counter-clockwise. Remove the outer arbor washer or flange
(D).
WARNING
Inspect the blade (F) for any damage. Do not use any
blade that has cracks, nicks, flaws or a damaged arbor.
Make sure the blade is marked with a maximum operat-
ing speed greater than 4450 rpm.

Step 4
Match the blade tri-arbor to the blade shaft arbor and install
the blade firmly against the rear flange (E). Insure the blade is
installed on the tri-arbor correctly. Match the female tri-arbor of
the outer washer or flange with the blade shaft and install the
blade shaft bolt turning clockwise. Be sure the outer flange is
fully seated and firmly holding the diamond blade in position.
Step 5
Install the blade cover (A) by turning the two knobs and tighten
until fully seated against the blade block.
When replacing a worn blade, thoroughly clean the concrete
from blade block and blade cover before installing the new
blade. Discard the old skid plate and replace it with a new skid
plate.
NOTE:
Use the 1/4" wide guide wheels (front and rear included
with the saw) when chasing 1/4" saw cuts with the XL6-
V25-D blade. To replace guide wheels, remove lock nut
and slide out the shoulder bolt. Make note of the washers
and other parts removed and the order of assembly. Slide
the bronze bushing from inside the old guide wheel and
insert into the new one. Both front and rear guide wheels
must be replaced; do not mix different width guide wheels.
Install the new guide wheels using the same shoulder
bolts, lock nuts and plastic washers.
Half-inch wide guide wheels (not included with the saw) also
available for use with ProEdge Blade XL6-V500-D, when chas-
ing 1/2" wide saw cuts.
