OPERATION
CLEAR A CLOGGED DISCHARGE CHUTE
WARNING: Hand contact with the rotating impeller
inside the discharge chute is the most common cause of
injury associated with snowthrowers. Never clear or
unclog discharge chute with your hands, or while engine
is running. Fingers can quickly become caught and
traumatic amputation or severe laceration can result.
• SHUT OFF THE ENGINE!
• Wait 10 seconds to be sure that the impeller blades have
stopped rotating.
• Always use a clean-out tool, not your hands.
A clean-out tool (A, Figure 10) is attached to either the handle or the
top of the auger housing. Use the clean-out tool to remove snow from
the auger housing.
A
OPERATING TIPS
1. Most efficient snowthrowing is accomplished when snow is
removed immediately after it falls.
2. For complete snow removal, slightly overlap each swath previously taken.
3. Snow should be discharged downwind whenever possible.
4. For normal usage, set the skids 1/8 inch (3 mm) below the
scraper bar. For extremely hard-packed snow surfaces, the
skids may be adjusted upward to ensure cleaning efficiency.
5. On gravel or crushed rock surfaces, the skids should be set at
1-1/4 inch (32 mm) below the scraper bar (see “Adjust Skid
Height” in the Maintenance section of this manual). Rocks
and gravel must not be picked up and thrown by the machine.
6. After the snowthrowing job has been completed, allow the engine to idle for a few minutes, to melt snow and ice accumulated on the engine.
7. Clean the snowthrower thoroughly after each use.
8. Remove ice and snow accumulation and all debris from the
entire snowthrower, and flush with water (if possible) to remove all salt or other chemicals. Wipe snowthrower dry.
9. Before starting snowthrower, always inspect augers and impeller for ice accumulation and/or debris, which could result in
snowthrower damage.
10. Check oil level before every start. Make sure the oil is at the
FULL mark on the oil fill cap/dipstick.

each 8 hours of continuous use. Add the recommended motor oil
as required.
NOTE: Over filling the engine can affect performance. Tighten
the oil fill cap securely to prevent leakage.
Change Oil - Every 50 hours of operation or at least once a year,
even if the snowthrower is not used for fifty hours. Use a clean,
high quality detergent oil. Fill the crankcase to FULL line on dipstick (A, Figure 11). Be sure original container is marked: A.P.I.
service “SF” or higher. Do not use SAE10W40 oil (as it may not
provide proper lubrication). See Chart for oil recommendations.
* Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W-30 may cause increased oil consumption. Check
oil level more frequently.

MAINTENANCE
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 13) 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.
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.

Power Rating
The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engineers) code
J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and corrected in accordance with
SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepower values are derived at 3600 RPM. Net power values
are taken with exhaust and air cleaner installed whereas gross power values are collected without these attachments. Actual gross engine
power will be higher than net engine power and is affected by, among other things, ambient operating conditions and engine-to-engine
variability. Given the wide array of products on which engines are placed, the gas engine may not develop the rated gross power when
used in a given piece of power equipment. This difference is due to a variety of factors including, but not limited to, the variety of engine
components (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions
(temperature, humidity, altitude), and engine-to-engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton may
substitute an engine of higher rated power for this Series engine.
