during
Danger from rotating impeller 丨Stop
the engine before installing or removing
the blower tubes! Never perform any
maintenance or assembly procedures
on this machine while the engine is
running!
WARNING!
Danger of fire! Never transfer or store
fuels in the presence of combustible
materials I Before starting the engine,
always move the blower to a clear area
at least 10-feet (3*metres) away from
fuels and other combustible materials!
CAUTION!
Never attempt to mix fuel in the blower fuel tank! Always mix all fuels in a clean, approved
container!
Some Fuel contains alcohol as an oxygenate! Oxygenated fuels may cause increased
engine operating temperatures! Under certain conditions ，alcohol-based fuels may also
reduce the lubricating qualities of some mixing oils! Never use any fuel containing more
than 10% alcohol by volume! When an oxygenated fuel must be used, fuel containing an
ether-based oxygenate such as MTBE is preferred over alcohol!
Whenever possible, use 2-cycle engine oil or equivalent oil mixed at a 25-30:1 ratio. Be
aware that generic oils and some outboard mixing oils may not be intended for use in high
performance air cooled 2-cycle engines, and should never be used in your engine blower.

STARTING THE BLOWER
IMPORTANT
An “ON-OFF” switch located on the left of
the blower handle grip controls the engine
ignition.
Starting Procedure:
1. Prime the fuel system by repeatedly
depressing the fuel primer bulb until
no air bubbles are visible in the fuel
discharge line.
2. Cold Engine Only. Choke the engine
by pulling the choke control to the
fully extended position (choke is
closed).
3. Place the blower on the ground, hold
the blower handle firmly with your right
hand.
4. Pull the starter cord slowly until you feel the starter engine, then…
5. ..start the blower by pulling the starter cord upward rapidly
If necessary, repeat step 5 two or three times until the engine starts.

WHEN THE ENGINE STARTS
IMPORTANT!!
For maximum blower performance and operating life, allow the engine to warm before use.
1. Run the engine at idle speed until operating temperature is reached (2 to 3 minutes)
2. As the engine warms open the choke gradually by slowly pushing the choke control in
to the fully retracted position.
3. The blower should now be ready for use.
IF THE ENGINE DOES NOT START
Repeat the appropriate starting procedures for ‘hot’ or ‘cold’ engine. If the engine still will not
start, follow the ‘Starting a Flooded Engine procedure (below).
STARTING A FLOODED ENGINE
1. Disconnect the spark plug lead, use the
spark plug wrench to remove the plug in
a counterclockwise direction.
2. If the spark plug is fouled or is soaked
with fuel, clean or replace the plug as
required.
3. Clear excess fuel from the combustion
chamber by cranking the engine several
times while the spark plug is removed.
4. Install the spark plug and firmly tighten
it with the spark plug wrench. If a
torque wrench is available, torque the
spark plug to 148-165 inch-pounds.
Reconnect the spark plug lead.
5. Repeat the starting procedures for
‘warm engine’;
6. If the engine still fails to fire or start,
refer to the troubleshooting flowchart
at the end of this manual.
Use low throttle settings when clearing lightweight materials from around lawns or
shrubbery;
Use medium to higher throttle settings to move lightweight grass or leaves from parking
lots or walkways. Use full throttle when moving heavy loads such as dirt or snow.

IMPORTANT!
Blower noise increases at higher throttle settings! Always use the lowest throttle setting
required to get the job done!
.
ROUTINE MAINTENANCE
Daily Maintenance:
Remove dirt and debris from the blower exterior;
Inspect the engine, tank and hoses for possible fuel leaks and repair as necessary;

Before removing the spark plug, thoroughly clean the spark plug and cylinder head
area!
Allow the engine to cool before servicing the spark plug!
Do not complete cylinder tightening or loosening of the spark plug while the engine is hot!
Incorrect spark plug installation can result in serious engine damage!

EVERY 50 HOURS:
(More frequently if you note reduced performance)
INSPECTION: inspect the entire blower and/or
missing tubes for damage, including components
and repair as necessary.
SPARK PLUG: Replace the spark plug with a
champion RCJ6Y gapped to 0.6-0.7mm;
FUEL FILTER: Use a wire hook to extract the fuel
filter from inside the fuel tank, and then remove and
wash the filter element in clean fuel. Before re
installing the filter, inspect the condition of the fuel
line. If damage or deterioration is noted, the blower
should be removed from service until it can be
inspected by a trained service technician.
COOLING
SYSTEM: Remove the engine cover (as described
under “Spark Arrestor”) and use a wood or plastic
scraper and soft brush to remove dirt and debris from the cylinder fins and crankcase.

SPARK ARRESTOR MAINTENANCE:
Hard starting or a gradual loss of performance can be caused by carbon deposits lodged in the
spark ancestor screen. For maximum performance, the spark arrestor screen should be
periodically cleaned as follows:

1. Remove the spark plug;
2. Remove three self-tapping screws and two machine screws from the engine cover and
then gently move the engine cover aside;
3. Remove the three spark arrestor retaining screws, then remove the spark arrestor cover,
screen, gasket and chamber;
4. Use a plastic scraper or wire brush to remove carbon deposits from the screen,
chamber and cover;
5. Inspect the screen carefully and replace any screen that has been performed, distorted
or is otherwise unserviceable;
6. Install the chamber, screen, gasket and cover in the reverse order of disassembly and
then install and securely tighten the three cover retaining screws;
7. Install the engine cover and verify that the fuel line connections are still tightly in place;
8. Install the engine cover retaining screws in the reverse order of removal and tighten
securely;
9. Install and tighten the spark plug, and reconnect the spark plug wire;
STORAGE: (30
days or longer):
CLEANING: Thoroughly the blower exterior;
INSPECTION: Inspect the entire blower and tubes for damage, including loose or missing
components and repair as necessary;
FUEL: Drain the fuel tank and then clear the carburetor and lines by running the blower until it
stops from lack of fuel;
