STARTING AND STOPPING INSTRUCTIONS
WARNING:
Only operate this unit in a well-ventilated outdoor area. Carbon monoxide exhaust fumes
can be lethal in a confined area.
WARNING:
Avoid accidental starting. Make sure you are in the starting position when pulling the starter
rope (Fig. 11). To avoid serious injury, the operator and unit must be in a stable position while starting.
Do not set unit on any surface except a clean, hard area while starting. Debris such as gravel, sand, dust
and grass could be picked up by the air intake and thrown out by the discharge opening. This could
damage the unit, property, or cause serious injury to bystanders or the operator.
STARTING INSTRUCTIONS
1. Mix gas with oil. Fill fuel tank with fuel/oil mixture. See Oil and Fuel Mixing Instructions.
WARNING:
To avoid serious personal injury, always remove the vacuum bag prior to refueling the
unit. The bag may become a fire hazard when saturated with fuel.
NOTE: The throttle control will remain in the position it's placed until
moved. Fast position is to the right. Also, there is no need to
turn the unit on. The On/Off Control is in the ON (I) position
at all times.
2. Set the blower/vacuum mode change-over lever to the up
position (Blower Mode). See Operating as a Blower. This prevents
the vacuum bag from filling up while starting the engine.
3. Fully press and release the primer bulb 10 times, slowly. Some
amount of fuel should be visible in the primer bulb and fuel lines
(Fig. 10). If you can't see fuel in the bulb, press and release the
bulb as many times as it takes before you can see fuel in it.
4. Place the choke lever in Position 1 (Fig. 10).
5. Place the unit in the starting position (Fig. 11). Move the throttle
control to the FAST POSITION ( ) (Fig. 9).
6. Crouch in the starting position (Fig. 11) and pull the starter rope in
a controlled motion 5 times.
NOTE: The unit uses Spring Assist Starting™, which significantly
reduces the effort required to start the engine. You must pull
the starter rope out far enough to hear the engine attempt to
start. There is no need to pull the rope briskly- there is no
harsh resistance when pulling. Be aware that this starting
method is vastly different from (and much easier than) what
you may be used to.
7. Place the choke lever in Position 2 (Fig. 10).
8. Pull the starter rope 3-5 times in a controlled motion to start the
engine.
9. Keep the throttle control in the FAST POSITION (
the engine to warm up for 30 to 60 seconds.
NOTE: Engine may take longer to warm up and reach maximum
operating speed at colder temperatures.
NOTE: Unit is properly warmed up when engine accelerates without
hesitation.
10. Move the choke lever to Position 3 (Fig. 10).
11. Keep the throttle control in the FAST POSITION (
warming the engine for an additional 60 seconds. During this time
the unit may be used.
IF... the engine hesitates, return the choke lever to Position 2
(Fig. 10) and continue to warm-up.
IF... the engine does not start, go back to step 3.
IF... the engine fails to start after a few attempts, place the choke
lever in Position 3 and move the throttle control to the FAST
POSITION ( ). Pull the starter rope out with a controlled
and steady motion 3-8 times. The engine should start. If not, repeat.
IF WARM... If the engine is already warm, start the unit with the choke lever in Position 2. After the unit starts, move
the choke lever to Position 3.
STOPPING INSTRUCTIONS
1. Move the throttle control to the IDLE POSITION (
2. Press the On/Off Stop Control switch in the OFF (O) position and hold until the engine comes to a complete stop.

OPERATING TIPS
WARNING:
To prevent serious personal injury or
damage to the unit, make sure blower tubes or
vacuum tubes and the vacuum bag are in place
before you operate the unit.
• Be sure the vacuum bag is zipped closed before operating the unit.
• Assure the unit is not directed at anybody or at any loose debris
before starting the unit.
• Verify that the unit is in good working condition. Make sure the
tubes and guards are in place and secure.
• Always hold the unit with both hands when operating. Keep a firm
grip on both the front and rear handle or grips.
• 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.
• 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.
• Watch out for children, pets, open windows or freshly washed
cars, and blow debris safely away.
• Use the full blower nozzle extension so the air stream can work close to the ground.
• Clean up after using blowers and other equipment. Dispose of debris appropriately.

Vacuum Operation Procedures
Lever
Check for the following before operating the unit:
• 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, operator is equipped with a dust mask
or face mask
• The unit is in good working condition - the vacuum tubes and
vacuum bag are in place and secure.
• The shoulder harness is in place and correctly adjusted. Use the
unit for vacuuming up light debris like leaves and paper.
Hold the vacuum, tilting the suction tube slightly (2-4 in or 50-100
mm), and use a sweeping action to collect light debris (Fig. 18). The
debris will flow into the vacuum bag. Items 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.
WARNING:
never unzip the vacuum bag without stopping the
unit first.
WARNING:
Avoid situations that could catch the
vacuum bag on fire. Do not operate near an open flame.
Do not vacuum warm ash from fireplaces, barbecue
pits, brush piles, etc. Do not vacuum discarded cigars
or cigarettes unless the cinders are completely cool.
When the bag is full, suction will noticeably decrease. Turn off the unit
before removing the bag. Remove and unzip the bag and empty the
contents before continuing.
NOTE: Empty the bag after each use to avoid deterioration and
obstructing air flow, which will reduce the performance of
the vacuum.
PATIO HEAD
NOTE: To use the patio head, the unit must be operated as a vacuum.
See the Operating as a Vacuum section of your manual.
Installation
1. While the engine is off, turn the unit so that the blower/vacuum
tube openings point straight up (Fig. 19).
2. Place the round opening of the patio head into the round vacuum
opening (Fig. 20).
3. Press down until the patio head seats into place.
Operation
Hold the vacuum, tilting the blower/vacuum tube down. The patio head
should roll without scraping; adjust the angle of the tube so that the patio
head opening runs parallel to the ground. Use a forward and backward
motion to vacuum up debris (Fig. 21). Small leaves and twigs will flow into
the vacuum bag and be mulched as they pass through the fan housing,
allowing the vacuum bag to hold more debris. DO NOT attempt to
vacuum up materials that are larger than the patio head openings.
When the bag is full, suction will noticeably decrease. Turn off the unit
before removing the bag. Unzip the bag and empty the contents
before continuing.
