To clear the discharge chute:

1. Shut off the engine.

2. Wait 10 seconds and make sure impeller blades 

have stopped rotating.

3. Remove the snow clean-out tool (1) from the 

auger housing and use it to remove the clog from 
the discharge chute.

4. Replace the snow clean-out tool on the auger 

housing.

Discharge Chute Deflector

ALWAYS position discharge chute deflector at a safe 
angle before starting engine.

DO NOT throw snow any higher than necessary.

Push deflector handle forward or down to throw snow 
lower. Pull deflector handle up or to the rear to throw 
snow higher.

IMPORTANT: If Chute Deflector does not stay in set 
position, adjust as directed in Discharge Chute 
Deflector
 on page 17,
 or repair before operation.

Discharge Chute 

Discharge chute rotates 200°.

ALWAYS position discharge chute in safe direction and 
angle, away from operator and bystanders, before 
starting engine.

Chute Crank

IMPORTANT:  If chute does not stay in set position, 
adjust as directed in Discharge Chute on page 18, or 
repair before operation.

Rotate the Chute with Discharge Chute Crank.

IMPORTANT: DO NOT force frozen chute controls. If 
still frozen, take to warm place until controls are free.

Scraper Blade

The scraper blade allows the back of the housing to 
keep better contact with the surface being cleared. It 
also prevents damage to the housing from normal 
wear.

IMPORTANT: DO NOT allow Scraper Blade to wear 
too far or Auger/Impeller housing will become 
damaged.

Runners

The runners control the distance between the scraper 
blade and the ground. Adjust runners equally to keep 
blade level with the ground. Refer to Pre-Start on 
page 13 fo
r recommended settings.

FILLING FUEL TANK

To add fuel to fuel tank: 

1. ALWAYS place unit in open or well-ventilated 

area.

2. Stop engine and allow to cool.

3. Clean Fuel Cap and surrounding area to prevent 

dirt from entering Fuel Tank. 

4. Remove Cap.

IMPORTANT: DO NOT use gasohol or gasoline 
containing alcohol. See Engine Manual for correct type 
and grade of fuel.

5. Fill fuel tank to within 1/2 in. (1.2 cm) below 

bottom of filler neck with unleaded gasoline. 

NOTE: Tank capacity is 2 qt (1.96 L). 

6. Replace Fuel Cap and tighten.

7. ALWAYS clean up any spilled fuel.

PRE-START

 1. Frozen Impeller

IMPORTANT: Before starting engine, check impeller to 
be sure it is not frozen.

1. With ignition key switch in “Stop” position, 

squeeze Attachment Clutch Lever to Engaged 
position. 

2. Pull Recoil Starter Handle. 

3. If Impeller is frozen, (cannot pull Starter Handle) 

move unit to a heated area and thaw to prevent 
possible damage.

 2. Check Function of Clutches

If clutches do not engage or disengage properly, adjust 
or repair before operation (see Check Clutch Operation 
on page 15). 

 3. Check Runners

Check and adjust Runners (see Runners on page 17). 
Allow 1/8 in. (3 mm) between scraper blade and hard, 
smooth surface(s). Allow 1-1/4 in. (30 mm) between 
scraper blade and uneven or gravel surfaces.
