gasoline from leaking and then gently pull the fuel line
off the fuel tank fitting. Drain the gasoline into the pan
and then transfer the gasoline to a container
designed for fuel storage.
4. Re-install the fuel line on the fuel tank fitting and
secure it in place with the hose clamp. Install gas cap

O. With a 3/8" wrench, remove the three bolts that
secure the engine mounting base to the deck. One bolt
is shown in Figure 26. A second bolt is located at the
rear of the machine above the left side of the blower
opening. This second bolt also secures the short wire
leading to the safety interlock. Remove the wire and the
lockwasher along with this bolt. Also, disconnect the
long safety interlock wire where it attaches to the enigine
above the engine muffler. A third bolt is located near the
right front wheel.
E. Remove the two hair pin clips on the right side and
rear of the housing which secure the shredder screen
rods, and then remove the rods and shredder screen.
F. Slide the engine forward (in direction of the spark
plug) and carefully lift engine out of chassis. Gently

sharp.

G. The chipper cutting blade (A in Figure 27 on Page
27) is mounted on the upper side of the flywheel
assembly (B). AVOID CONTACT WITH THE BLADE
AS IT IS EXTREMELY SHARP! To remove the blade,
first remove the flywheel assembly as described below:
1. Rotate the flywheel assembly until the cutout (C)
in the flywheel assembly is located below the chipper
chute. To prevent the flywheel assembly from
turning, place a 1/2" or thicker wood dowel down the
chipper chute through the cutout. See Figure 27.
2. Using a box end 9/16" wrench, remove the
bolt (0) and concave washer (E). Carefully slide the
assembly off the crankshaft. Do not lose the key (F),
or any shims (G). NOTE: Shims (if used) may be
inside bore of flywheel assembly. See Figure 27.
H. With a 3/16" hex key (Allen) wrench and 1/2" box
wrench, remove the two locknuts (I) and screws (H) that
secure the blade to flywheel assembly. If necessary,
first clean out the socket holes in the screw heads with a
sharp nail or awl. See Figure 27.
I. Before installing a new or resharpened blade,
thoroughly clean the area where the blade seats on the
flywheel assembly (also clean the old blade, if it is being
reused).
J.
Position the blade on the upper side of the flywheel
assembly, with the sharp edge of the blade on top.
Install two
new screws down through the blade and add
new locknuts. Use only factory-supplied hardware.
Do not use substitutes or equipment failure or
personal injury could result. Tighten securely (torque
to 240 Ibs-in or 20 Ibs-ft).
