REPLACING THE SPARK PLUG
Use a replacement part number
753-06193
. The correct spark gap is
0.025 in.
(0.635 mm)
.
1. Stop the engine and allow it to cool.
2. Grasp the plug boot firmly and pull the cap from the spark plug.
3. Clean dirt from around the spark plug. Remove the spark plug from the cylinder head by turning a
5/8 in. socket counterclockwise.
4. Replace cracked, fouled or dirty spark plug. Set the spark gap at 0.025 in. (0.635 mm) using a feeler
gauge (Fig. 21).
5. Install a correctly-gapped spark plug in the cylinder head. Turn the 5/8 in. socket clockwise until snug.
If using a torque wrench, torque to:
110-120 in.•lb. (12.3-13.5 N•m) Do not over tighten.
6. Reinstall the spark plug boot.
IDLE SPEED ADJUSTMENT
The idle speed of the engine is adjustable. An idle adjustment screw is
between the air filter cover and the engine starter housing (Fig. 20).
NOTE:
Careless adjustments can seriously damage your unit. An authorized service dealer should make
carburetor adjustments.
If, after checking the fuel and cleaning the air filter, the engine still will not idle, adjust the idle speed
screw as follows:
1. Start the engine and let it run at a high idle for a minute to warm up. Refer to
Starting/Stopping
Instructions
.
2. Release the throttle trigger and let the engine idle. If the engine stops, insert a small Phillips in
between the air filter cover and the engine cover (Fig. 20). Turn the idle speed screw in, clockwise,
1/8 of a turn at a time (as needed) until the engine idles smoothly.
AIR FILTER MAINTENANCE
Cleaning the Air Filter
Failure to maintain your air filter properly can result in poor performance or
can cause permanent damage to your engine.
1. To open the air filter cover, push the locking tab on the right side of the
cover inward and pull the air filter cover slightly out and to the left (Fig. 17).
2. Remove the air filter (Fig. 18).
3. Wash the filter in detergent and water. Rinse the filter thoroughly and
allow it to dry.
4. Apply enough clean SAE 30 motor oil to lightly coat the filter.
5. Squeeze the filter to spread and remove excess oil.
6. Replace the filter (Fig. 18).
NOTE:
If the unit is operated without the air filter, you will VOID the warranty.
7. To reinstall the air filter cover, position the hooks on the left side of the
air filter cover into the slots at the left side of the back plate (Fig. 18).
8. Swing the cover to the right and press closed so the air filter cover tab
snaps into the slot on the back plate (Fig. 19).
OPERATING THE UNIT AS A BLOWER
Use the blower for trees, shrubs, flower beds and hard-to-clean areas.
Also use the unit around buildings, walls, overhangs, fences and screens,
and for other normal cleaning procedures. Conserve water by using power
blowers instead of hoses for many lawn and garden applications,
including areas such as gutters, screens, patios, grills, porches and gardens.
Hold the blower with the right hand. Do not stand on the right side of the blower when operating the
unit (Fig. 14). If you do, you will be blocking the air intake and this will affect the unit’s performance.
Instead, be sure to stand on the left side of the unit to maximize the unit’s efficiency (Fig. 14).
Sweep from side to side with the nozzle several inches above the ground or floor. Slowly advance the
unit, keeping the accumulated pile of debris in front of you.
Most dry blowing operations are better suited to low speeds, rather than high. High speed blowing is a
better way to move heavier items like large debris or gravel.
OPERATING THE UNIT AS A VACUUM
Use the unit for vacuuming up light debris like leaves and paper.
Be sure the vacuum bag is zipped closed before operating the unit.
Place the shoulder harness over your head and onto your shoulder. Hold the vacuum with both on
hands on the handle (Fig. 15), tilting the suction tube slightly, and use a sweeping action to collect light
debris (Fig. 16). The debris will flow into the vacuum bag. Things such as small leaves and small twigs
will be mulched as they pass through the fan housing, allowing the vacuum bag to hold more debris.
Emptying the Vacuum Bag
When the bag is full, suction will noticeably decrease. Turn off the unit and allow the impeller to stop
before you unzip the bag.
1. While wearing eye protection and a dust mask, unzip the vacuum bag and empty the contents into a
garbage bag or container.
2. Turn the bag inside out after initial emptying and vigorously shake out dust and debris.
3. Zip close and reinstall the vacuum bag.
NOTE:
Empty the bag after each use to avoid deterioration and obstructing air flow, which will reduce
the performance of the vacuum.
CLEANING
Use a small brush to clean off the outside of the unit. Do not use strong detergents. Household cleaners
that contain aromatic oils such as pine and lemon, and solvents such as kerosene, can damage the
plastic housing or handle. Wipe off any moisture with a soft cloth.
STORAGE
• Never store a fueled unit where fumes may reach an open flame or spark.
• Allow the engine to cool before storing.
• Store the unit locked up to prevent unauthorized use or damage.
• Store the unit in a dry, well-ventilated area.
• Store the unit out of the reach of children.
Long Term Storage
1. Remove the fuel cap, tip the unit and drain the fuel into an approved container.
NOTE:
Do not use fuel that has been stored for more than 30 days. Dispose of the old fuel/oil mix in
accordance with federal, state and local regulations.
2. Start the engine and allow it to run until it stalls. This ensures that all fuel has been drained from the
carburetor.
3. Allow the engine to cool. Remove the spark plug and put 5 drops of any high quality motor oil or
2-cycle oil into the cylinder. Pull the starter rope slowly to distribute the oil. Reinstall the spark plug.
NOTE:
Remove the spark plug and drain all of the oil from the cylinder before attempting to start the unit
after storage.
4. Thoroughly clean the unit and inspect it for any loose or damaged parts. Repair or replace damaged
parts and tighten loose screws, nuts or bolts. The unit is ready for storage.
