Clearing a Clogged Discharge Chute

DANGER

Amputation hazard

The discharge chute contains a rotating impeller

to throw snow. Fingers can quickly become caught

in the impeller. Never clear or unclog the discharge

chute with your hands. Always use a clean-out tool.

Failure to observe these safety instructions will

result in traumatic amputation or severe laceration.

Hand contact with the rotating impeller inside the

discharge chute is the most common cause of injury

associated with snowthrowers. Never use your hands to

clean out the discharge chute.

To safely clear a clogged discharge chute, follow

these instructions:

1. Shut OFF the engine.

2. Wait 10 seconds to be sure the impeller blades have

stopped rotating.

3. Always use a clean-out tool, not your hands.

A clean-out tool (A, Figure 11) is provided with the unit.

Skid Shoe Height Adjustment

DANGER

Amputation hazard

The discharge chute contains a rotating impeller to throw

snow. Fingers can quickly become caught and traumatic

amputation or severe laceration will result. Hand contact

with the rotating impeller inside the discharge chute

is the most common cause of injury associated with

snowthrowers.

Turn the engine OFF, wait for all moving parts to stop,

and remove the engine key before performing any

maintenance or repairs.

WARNING

Thrown objects hazard

Objects such as gravel, rocks, or other debris, if struck by

the impeller, may be thrown with sufficient force to cause

personal injury, property damage, or damage to the

snowthrower.

Be sure to set the skid shoes at the proper height to

maintain ground clearance for the type of surface being

cleared.

This snowthrower is equipped with two height adjust skids,

secured to the outside of the auger housing. These elevate

the front of the snowthrower.

When removing snow from a hard surface area such as

a paved driveway or walk, adjust the skids up to bring the

front of the snowthrower down.

When removing snow from rock or uneven construction,

raise the front of the snowthrower by moving the skids

down. This will help to prevent rocks and other debris from

being picked up and thrown by the augers.

1. Determine how much clearance you want between the

scraper bar at the bottom of the auger housing and the

ground. If clearing a gravel surface, enough ground

clearance is needed to prevent the unit from picking up

rocks.

2. Place a block equal to the desired ground clearance

under the scraper bar.

3. Loosen the skid shoe mounting nuts (A, Figure 12) and

push the skid shoe (B) down until it touches the ground.

Re-tighten mounting nuts.

4. Set the skid shoe on the other side at the same height.

WARNING

Fuel and its vapors are extremely flammable and

explossive. Always handle fuel with extreme care.

Failure to observe these safety instructions can cause a

fire or explosion which will result in severe burns or death.

When Storing Gasoline or Equipment With Fuel in

Tank

• Store away from furnaces, stoves, water heaters, or other

appliances that have pilot light or other ignition source

because they can ignite fuel vapors.

Fuel System

Fuel can become stale when stored over 30 days. Stale fuel

causes acid and gum deposits to form in the fuel system

or on essential carburetor parts. To keep fuel fresh, use

Briggs & Stratton® Advanced Formula Fuel Treatment

& Stabilizer, available wherever Briggs & Stratton genuine

service parts are sold.

There is no need to drain gasoline from the engine if a fuel

stabilizer is added according to instructions. Run the engine

for 2 minutes to circulate the stabilizer throughout the fuel

system before storage. If gasoline in the engine has not

been treated with a fuel stabilizer, it must be drained into an

approved container. Run the engine until it stops from lack

of fuel. The use of a fuel stabilizer in the storage container is

recommended to maintain freshness.

Engine Oil

While the engine is still warm, change the engine oil. See

Maintenance.

Before Placing in Storage

1. Thoroughly clean the snowthrower.

2. Remove the sparkplug. Clean and re-gap, if necessary,

or replace the sparkplug.

3. Make sure all nuts, bolts, and screws are securely

fastened.

4. Inspect moving parts for wear or damage. Replace

parts as necessary.

5. Lubricate the controls and moving parts.

6. Spray unpainted metal surfaces with a rust preventative.

7. Fold down the upper handle, if desired.

8. For indoor storage, cover the snowthrower and store it

in a dry area away from furnaces, stoves, water heaters,

or other appliances that have pilot lights or other ignition

sources.

9. For outdoor storage, raise the snowthrower off the

ground and cover it with a heavy tarpaulin.

After Removing from Storage

1. Raise the upper handle and tighten the handle knobs

securely.

2. Remove the oil dipstick and check the oil level. If

necessary, add oil until the level reaches the FULL mark

on the oil dipstick. Do not overfill.
