If any adjustments are made to the engine while the engine is running (e.g. carburetor), keep clear of all moving parts. Be careful of heated surfaces and muffler.
If carburetor needs adjustment to start or for opera

manual.

MAINTENANCE AND LUBRICATION

Your leaf blower, like all machines with moving parts,
must receive care and maintenance. The following tips, if used, will contribute many troublefree hours to your blower.
1. Check oil level frequently. When changing oil, make sure dirt and debris is cleaned off oil sump before removing oil plug.
2. Keep blower clean, especially the engine and engine air filter.
3. Check all nuts, bolts and screws occasionally to be sure blower is in good operating condition.
4. The wheel bearings are pre-lubricated at the factory and should require no further attention until blower is serviced. However, it is advisable to remove the wheels and apply a small amount of light oil to each axle at least once a season.
FIGURE 6.

HEIGHT ADJUSTMENT

The height adjustment crank is located on the richt hand side of the leaf blower. See figure 7. Turn the crank clockwise to raise the discharge chute. Turn the crank counter-clockwise to lower.

OFF-SEASON STORAGE

If you are going to store your blower for any length of time (30 days or longer), it is important that the following steps be taken:
1. Drain the gas tank. Start the engine. Allow it to run out of gas. Gasoline left in the engine will leave gum deposits in the carburetor and gas tank.
2. Clean engine of all foreign matter.
3. Lubricate cylinder by removing the spark plug and pour in one ounce of clean lubricating oil through the spark plug hole into the cylinder. Crank engine slowly to spread oil and replace spark plug. To start after* storage, remove spark plug and rotate engine with starter to remove excess oil.

NOTE

When storing any type of power equipment in an unventilated or metal storage shed, care should be taken to
rust proof the equipment. Using a light oil or silicone, coat the equip
ment, especially springs and bearinigs.
