Adjusting the Backpack Harness and Control Handle
1. Place the blower on your back by slipping arms through the shoulder straps as if you were putting on a
jacket.
2. Once adjustments have been made to the straps for user comfort, remove the blower from your back
and place on a level ground in an upright position.
3. Adjust the backpack harness and control handle position as required so that the unit is comfortable and
easy to control.
Fuel and Lubrication
Petrol/fuel/gasoline is extremely flammable – keep clear of naked flames or other
ignition sources. • The engine must be cool before refuelling. • Do not run the engine
on un-mixed fuel or fuel that is not mixed at the correct ratio.
Failure to use the correct fuel type / mixture
may permanently damage the engine and void product warranty
. • Mix the fuel thoroughly before adding
to the unit. • Some conventional petrol blends use oxygenates such as alcohol or other compounds to meet
emission requirements. This engine is designed to operate satisfactorily on any petrol for automotive use
including these types of blends.
Adequately fill the fuel tank with the correct fuel type.
•
Use non-ethanol unleaded mixed at a 40:1 ratio with 2-stroke engine oil (higher RON values and good
quality 2-stroke oil will provide best engine performance). Do not use old or contaminated fuel/oil. Fuel/oil
mix ratio examples are shown below.

Engine Idle Adjustment
In some cases due to operating conditions (altitude, temperature
etc.) the engine may not idle reliably after fully warming up. If this
occurs, a slight adjustment to the idle speed may be required.
1. Locate the carburettor idle adjustment screw (
G
).
2. Use a Phillips or slotted-screwdriver to rotate the idle
adjustment screw right (clockwise) 1/4 turn.
3. Check the idle. If the engine still does not idle reliably, repeat
step 2. If the engine still not idle or further adjustments are
necessary, take the machine to an authorised service centre.
