OPERATION
LITTLE
WONDER
BLOWER easily if it is moved while the clutch bail is released, particularly if going from forward to reverse.
BEFORE STARTING THE ENGINE
1. Read the Operator Manual and Engine Manual.
Become familiar with the controls, how each functions, and what it operates.
2. Check the engine oil level and add if necessary.
Curbs may be climbed by backing up the curb at an angle or by tipping the machine back and driving the front wheel over the curb. The back may then be lifted and the machine pushed forward onto the curb.
3 Fill the fuel tank with good quality, clean, unleaded regular gasoline (petrol). Use a funnel to avoid spilling.
To stop the engine, move the throttle control to the slow position and switch the engine off.
OPERATING INSTRUCTIONS
Air flow can be directed to the side or front by the two-position vertical deflector. The front discharge position is used to remove debris from along walls, fences, etc. The side discharge position is used to form windrows or piles. The horizontal deflector directs air downward to “chisel” under wet, heavy leaves and litter. Air speed is regulated by the throttle setting.
To reduce windrowing or to blow over an obstacle, point deflector upward.
To avoid blowing in an area, close deflector and reduce throttle setting.
Slight changes in deflector position will have a big effect on air flow. Experiment until you find the best position for your needs.
When clearing a yard or parking lot, planning how to blow it off can greatly reduce the total clearing time.
To operate the machine, select the desired speed with the speed/direction lever. Gradually engage the clutch bail until the machine begins to move. Con tinue to move the bail until it contacts the handle.
To stop the machine’s powered movement, release the bail.
Use the speed selector to change speeds.
-Do not “feather” or partially engage the clutch to slow speed. Doing so will rapidly wear the drive disc.
Change the setting of the speed/direction lever to vary speed.
-The speed/direction lever may be moved while the clutch bail is engaged. However, it will operate more
Slow the engine when moving from work site to work site. This will save fuel and prevent inadvertently blowing debris where you don’t want to.
NOTE: When transporting the machine by truck or trailer, close the fuel valve. This avoids the possibility of flooding should any dirt get under the carburetor float needle. Leaving the valve open can allow severe flooding which may ruin the engine by diluting the oil.

MAINTENANCE INSTRUCTIONS
Stop engine and remove the spark plug wire before performing any maintenance.
Keep blower air intake clear of debris for best performance.
Clear air discharge area of any debris accumulation.
Ensure machine has been shut off and fan is no longer moving before clearing.
Keep all hardware tight.
Check oil level daily. Top off as needed.
Change engine oil after the first 5 hours of operation.
Then change as recommended by the engine manufacturer.
1. Remove drain plug and drain oil while engine is warm.
2. Replace drain plug, remove fill plug and fill with new oil. See engine manual for oil specifications.
3. Start and run engine for 30 seconds. Stop engine.
4. Wait 30 seconds, then re-check oil level.
5. Top off if necessary. See engine manual for details.
MAINTENANCE
Lubricate chains every 40 hours or weekly, whichever comes first. Use a teflon containing chain lubricant such as bicycle chain lube that does not attract dirt. Bicycle chain lube is available at any bicycle shop or most places where bicycles are sold. Slots
A are provided in the chain covers to allow chain lubrication. Keeping the chains lubricated will greatly extend the like of both the chains and the sprockets.
(Figure 1)
Lubricate the hex shaft/trunnion assembly once a season or if moving the speed/direction lever becomes difficult. A teflon containing lubricant such as bicycle chain lube is recommended. To lubricate the hex shaft the bottom cover must be removed and the unit tipped up and to the right until it rests on the housing. The bottom cover is held by two nuts on the rear of the unit. (Figure 2)
Take care not to get any lubricant on either the drive or the driven disc. Any lubrication on these parts will cause slipping of the friction drive. Clean off any lubricant that gets on the drive or driven parts.

This limited warranty does not cover any defects due to repairs or alterations made to the product made by anyone other than
