HOLDING THE BLOWER
WARNING:
After starting the unit, always stand on the left side of the unit to operate
it as shown in figure 11 to keep from blocking the air intake.
Before operating the unit, stand in the operating position. Check for the following:
• Operator is wearing proper clothing, such as boots, safety glasses or goggles, ear/hearing protection,
gloves, long pants and long sleeve shirt
• If the conditions are dusty, the operator is wearing a dust mask or face mask
WARNING:
To avoid serious personal injury, wear goggles or safety glasses at all
times when operating this unit. Wear a face mask or dust mask in dusty locations.

OPERATING TIPS
WARNING:
To prevent serious personal injury or damage to the unit, make sure
blower tubes are in place before you operate the unit.
Using the Cruise Control
1. Once the engine has started and warmed up, squeeze
the trigger to accelerate the unit as needed (Fig. 10).
2. For longer periods of operation and to eliminate possible
finger fatique, move the cruise control toward the FAST
position to incrementally increase or maintain the unit's
engine speed (Fig. 10). When the cruise control is
pressed, the trigger will recede into the handle.
3. To decrease engine speed, move the cruise control to the
SLOW position and the trigger will return to idle (Fig. 10).
MAINTENANCE SCHEDULE
WARNING:
To prevent serious injury, never perform maintenance or repairs with unit
running. Always service and repair a cool unit. Disconnect the spark plug wire to ensure
that the unit cannot start.
Perform these required maintenance procedures at the frequency stated in the table. These procedures
should also be a part of any seasonal tune-up.
NOTE: Some maintenance procedures may require special tools or skills. If you are unsure about these
procedures take your unit to any non-road engine repair establishment, individual or authorized
service dealer.
NOTE: Maintenance, replacement, or repair of the emission control devices and system may be performed
by any non-road engine repair establishment, individual or authorized service dealer.
FREQUENCY
Before using Fill fuel tank with fresh fuel mixture*
Every 10 hrs Clean and re-oil air filter
Every 25 hrs Check spark plug condition and gap
Check the spark arrestor screen
DO NOT use E85 fuel in this unit. It has been proven that fuel containing greater than 15% ethanol
*
will likely damage this engine and void the warranty.
AIR FILTER MAINTENANCE
WARNING:
To avoid serious personal injury,
always turn your trimmer off and allow it to cool
before you clean or service it.
WARNING:
Wear gloves to prevent injury
when handling unit.
Cleaning the Air Filter
Clean and re-oil the air filter every 25 hours of operation. It is an
important item to maintain. Failure to maintain your air filter properly
can result in poor performance or can cause permanent damage to
your engine.
1. Open the air filter cover. Push the locking tab on the top of the
cover inward, then pull the air filter cover out and down. (Fig. 12).
2. Remove the air filter (Fig. 13).
3. Wash the filter in detergent and water (Fig. 14). Rinse the filter
thoroughly and allow it to dry.
4. Apply enough clean SAE 30 motor oil to lightly coat the filter
(Fig. 15).
5. Squeeze the filter to spread and remove excess oil (Fig. 16).
6. Replace the filter (Fig. 13).
NOTE: If the unit is operated without the air filter, you will VOID
the warranty.
7. Reinstall the air filter cover. Position the slots on the bottom of the
air filter cover onto the tabs at the bottom of the back plate (Fig. 13).
8. Swing the cover up until the tab on the air filter backplate
snaps into place in the slot on the air filter cover (Fig. 17).

Other Tips
• Assure the unit is not directed at anybody or any loose debris before starting the unit.
• Verify that the unit is in good working condition. Make sure the tubes are in place and secure.
• Always hold the unit securely when operating. Keep a firm grip on the handle.
• To reduce the risk of hearing loss associated with sound level(s), hearing protection is required.
• Operate power equipment only at reasonable hours— not early in the morning or late at night when
people might be disturbed. Comply with times listed in local ordinances. Usual recommendations are
9:00 am to 5:00 pm, Monday through Saturday.
• To reduce noise levels, limit the number of pieces of equipment used at any one time.
• To reduce noise levels, operate power blowers at the lowest possible speed to do the job.
• Check your equipment before operation, especially the muffler, air intakes and air filters.
• Use rakes and brooms to loosen debris before blowing.
• In dusty conditions, slightly dampen surfaces or use a mister attachment when water is available.
• Conserve water by using power blowers instead of hoses for many lawn and garden applications,
including areas such as screens, patios, grills, porches, and gardens.
• Watch out for children, pets, open windows or freshly
washed cars, and blow debris safely away.
• Clean up after using blowers and other equipment.
Dispose of debris appropriately.
• 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.
• Hold the blower with the right hand. Do not stand on
the right side of the blower when operating the unit (Fig.
11). 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. 11).

WARNING:

during idle speed adjustment. Wear protective
p 7
clothing and observe all safety instructions to
prevent serious personal injury.
Also, DO NOT set unit on any surface except a
clean, hard area while starting or performing any
adjustments. Debris, such as gravel, sand, dust,
grass, etc., could be thrown by the blower tube
and damage property or cause serious injury to
bystanders or operator.
The idle speed of the engine is adjustable. An idle adjustment screw
is between the air filter cover and the engine starter housing (Fig. 18).
NOTE: Careless adjustments can seriously damage your unit. An
authorized service dealer should make carburetor
adjustments.
Check Fuel Mixture
Old fuel is usually the reason for improper unit performance. Drain
and refill the tank with fresh fuel mixture prior to making any
adjustments. Refer to Oil and Fuel Information.
Clean Air Filter
The condition of the air filter is important to the operation of the
unit. A dirty air filter will restrict air flow. This is often mistaken for
an out of adjustment carburetor. Check the condition of the air
filter before adjusting the idle speed screw. Refer to Air Filter
Maintenance.
Adjust Idle Speed Screw
If, after checking the fuel and cleaning the air filter, the engine still
will not idle, adjust the idle speed screw as follows:
Locking Tab
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. 18). Turn the idle speed
screw in, clockwise, 1/8 of a turn at a time (as needed) until the engine idles smoothly.
Checking the fuel, cleaning the air filter, and adjusting the idle speed should solve most engine
problems. If not and all of the following are true:
• the engine will not idle
• the engine hesitates or stalls on acceleration
• there is a loss of engine power
Have the carburetor adjusted by an authorized service dealer.
