Simplicity 1692244, 1692243 Inspecting Cutting Edge, Reversing Cutting Edge, Shear bolts, Storage

Inspecting Cutting Edge

1. Raise snowthrower to highest position.

2.Use safety block(s) to secure snowthrower:

a.Place safety block under attachment.

b.Lower attachment until it rests on block(s).

3.Inspect location where cutting edge (A, figure 16) meets snowthrower housing.

Reversing Cutting Edge

1.Raise blower to highest position.

2.Use safety block(s) to secure blower.

a.Raise attachment to top height.

b.Place safety block under attachment.

c.Lower attachment until it rests on block(s).

3.Using l/2” wrench remove six (6) nuts, washers, and bolts (B, figure 16).

Shear bolts

Refer to figure 17 for discharge fan shear bolt (grade 3 hardness, 5/16” x 1”).

Refer to figure 18 for auger shear bolt (one in each auger- specialized, grade 3 hardness, 5/i 6” x 2”).

1.Check for excessive wear.

2.Shear bolt will break if auger or fan hits solid object. If this happens:

a.Stop snowthrower and tractor immediately. b. Stop engine, lock parking brake, remove key. c. Remove shear bolt.

d.Replace with new shear bolt. Make sure replace- ment shear bolt is Grade 3 hardness.

e. Locate and correct cause of shearing.

Storage

1.Clean snowthrower.

2.Check and repair or replace worn or damaged parts.

3.Paint appropriate areas to prevent rust.

4.Lubricate all necessary parts.

5.Cover and store.
