SNOW THROWING TIPS1. For maximum snow thrower efficien-
cy in removing snow, adjust groundspeed, NEVER the throttle. Goslower in deep, freezing or wetsnow. If the wheels slips, reduceforward speed. The engine is de-signed to deliver maximum perfor-mance at full throttle and should be
run at this power setting at all times.2. Most efficient snow throwing is ac-
complished when the snow is re-moved immediately after if falls.
3. For complete snow removal, slightlyoverlap each path previously taken.
4. The snow should be dischargeddown wind whenever possible.
5. For normal usage, set the skids sothat the scraper bar is 1/8" abovethe skids. For extremely hard-packed snow surfaces, adjust theskids upward so that the scraperbar touches the ground.
6. On gravel or crushed rock surfaces,set the skids at 1-1/4" below thescraper bar. See To Adjust SkidHeight paragraph in the Service &Adjustments section of this manu-al. Rocks and gravel must not bepicked up and thrown by the ma-chine.
.
.
9.
After the snow throwing job hasbeen completed, allow the engine toidle for a few minutes, which willmelt snow and accumulated ice off
the engine.Clean the snow thrower thoroughlyafter each use.
Remove ice and snow accumulationand all debris from the entire snow
thrower, and flush with water (if pos-sible) to remove all salt or otherchemicals. Wipe snow thrower dry.

ENGINE
,_ WARNING: Drain the gaso-line outdoors, away fromfire or flame.
Gasoline must be removed or treated to
prevent gum deposits from forming inthe fuel tank, filter, hose, and carburetorduring storage. Also, during storage al-cohol blended gasoline that uses etha-nol or methanol (sometimes calledgasohol) attracts water. It acts on thegasoline to form acids which damagethe engine.F-001088,.I

To remove gasoline, run the engineuntil the fuel tank is empty and theengine stops.
If you do not remove the gasoline,use fuel stabilizer supplied with unitor purchase Craftsman Fuel Stabi-lizer No. 3550. Add fuel stabilizer to
any gasoline left in the tank to mini-mize gum deposits and acids. If the
fuel tank is almost empty, mix stabi-lizer with fresh gasoline in a sepa-rate container and add some to thefuel tank.
Always follow the instruction on thestabilizer container. After the stabi-lizer is added to the fuel tank, runthe engine at least ten minutes toallow the mixture to reach the car-buretor.
Change the engine oil.
Lubricate the piston/cylinder area.First, remove the spark plug andsquirt a few drops of clean engineoil into the spark plug hole. Next,cover the spark plug hole with a ragto absorb oil spray. Then, pull two orthree times on the recoil starter ropeto rotate the engine. Finally, installthe spark plug and attach the sparkplug wire.
OTHER
1. If possible, store your snow throwerindoors and cover it to give protec-tion from dust and dirt.
2. If the machine must be stored out-
doors, block up the snow thrower tobe sure the entire machine is off the
ground.
3. Cover the snow thrower with a suit-
able protective cover that does notretain moisture. Do not use plastic.
