Install
the rotor blades with the thick layer on the
inside
of the curve. (Fig. 24). If you do not install the
blades properly
, the blades may be out of balance and
cause the snowthrower to “hop” or “bounce.”
2.
Insert the new rotor blade between the rotor halves.
3.
Secure the rotor blade to the rotor halves with two
hex-head capscrews, two spacers, and two locknuts,
positioning the bolt heads on the thick side of the
blade (Fig. 23).
4.
Curve the rotor blade and secure it with the remaining
torx screws and locknuts, positioning the screw heads
on the thick side of the blade (Fig. 23).
5. T
ighten all screws and locknuts securely

Preparing
the Fuel System
1. Add
a fuel stabilizer/conditioner to the gasoline in the
fuel tank as directed.
Note:
A fuel stabilizer/conditioner works best when you
mix it with fresh gasoline.
Note:
If you use
Tor
o Heavy Duty 50:1 All Season 2-Cycle
Engine Oil with Fuel Stabilizer
, you do not need to add a
fuel stabilizer/conditioner
.
