avoidanyarea with a sparkproducingelectricmotor,
or wherepowertoolsare operated.
6. If possible,alsoavoidstorageareaswith high humidity,
becausethat promotesrustand corrosion.
7. Keepthe enginelevelin storage.Tiltingcan causefuel
or oil leakage.
Removing
From Storage
1. Checkyourengineas describedin the Pre-Operation
Checksectionof this manual.
2. If the fuelwas drainedduringstoragepreparation, f ill
the tank with freshgasoline.If you keepa container
of gasolinefor refueling,makecertain it containsonly
freshfuel. Gasolineoxidizesand deterioratesover
time,causinghard starting.
3. If the cylinderwas coatedwith oil duringstorage
preparation, t he enginewill smokebrieflyat startup.
This is normal.
IMPORTANT: Do not spray engine with water to clean
because water could contaminate fuel. Using a garden
hose or pressure washing equipment can also force
water into the air cleaner or muffler opening. Water in
the air cleaner will soak the paper element, and water
