recessed in the hole toward the front of the blower (Fig. 4).
Insert a flat head screwdriver, into the hole and press the door
lock tab in and lift the door to release the lock.
2. While holding the impeller door open, align the upper vacuum

RECOMMENDED OIL TYPE
WARNING:
INJURY. Check and maintain the proper oil level in the crankcase; it is important and
cannot be overemphasized. Check the oil before each use and change it as needed. See
Changing the Oil.
Using the proper type and weight of oil in the crankcase is extremely important. Check the oil before
each use and change the oil regularly. Failure to use the correct oil, or using dirty oil, can cause
premature engine wear and failure.
Use a high-quality SAE 30 weight oil of API (American Petroleum
Institute) service class SJ.
ADDING OIL TO CRANKCASE: INITIAL USE
NOTE: This unit is shipped without oil in the engine. To avoid
damage to the unit, put oil in the crankcase prior to
starting the unit.
This unit is supplied with one 2.03 fl.oz. (60 ml) bottle of SAE 30
oil (Fig. 10).
NOTE: Save the empty oil bottle. It can be used to measure the
correct amount during future oil changes. See Changing
the Oil.
1. Unscrew the top of the bottle of oil and remove the paper seal
covering the opening. Replace the top and cut the tip off the
funnel spout (Fig. 10).
2. With the unit on a flat level surface, remove the oil plug (Fig. 11).
3. Pour the entire bottle of oil into the oil fill hole (Fig. 12).
NOTE: Never add oil to the fuel or fuel tank.
4. Wipe up any oil that may have spilled and reinstall the oil fill
plug.
Check oil before each use and change as needed. Refer to
Checking the Oil Level.
RECOMMENDED FUEL TYPE
Old fuel is the primary reason for poor unit performance. Be sure
to use fresh, clean, unleaded gasoline.
NOTE: This is a four cycle engine. In order to avoid damage to
the unit, do not mix oil with gasoline.
Definition of Blended Fuels

tank. Keep sparks and open flames at a distance from the area.
The use of a gas stabilizer will inhibit corrosion and minimize the formation of gum deposits for up to
six (6) months. Add 0.8 oz. (23 ml.) of fuel additive per gallon of fuel according to the instructions on
the container. NEVER add fuel additives directly to the unit's gas tank.
