Blower Assembly Instructions

*NOTE : Numbers in brackets (#) represent Key Numbers shown on Parts List, and parts explosion. See pages 6-8.

1.Install lower handles (30) on top of deck (32, 33). Secure with four cap screws 5/16-18 x 1 3/4 (34), four 5/16 flat silver washers (31), and four 5/16-18 nylon nuts (2), finger tight.

2.Install upper handle (17) with four cap screws 5/16-18 x

1 3/4 (34), eight 5/16 washers (31), and four 5/16-18 nylon nuts (2), finger tight. Tighten lower handle nuts and bolts. Tighten upper handle nuts and bolts until the lower handle tubing pinches the upper handle. It will be normal for the lower handle tubing to crush slightly.

3.Attach throttle cable to upper handle with 1/4-20 x 1 3/4" cap screw (19) and 1/4-20 lock nut (22) through hole on upper handle (17). For Briggs and Stratton INTEK series engines, the throttle control will mount on the right hand side. For Honda engines, it will mount on the left. Insert the 10-32 x 3/4" self-tapping screw through the hole of the throttle control and into the pilot hole in the handle and tighten. (NOTE: Over tightening the screw on the left hand mounted controls could cause damage to the control.) Once the 10-32 screw is tightened, go back to the 1/4-20 screw and tighten it enough to get a smooth action in the control. If the throttle does not maintain it’s setting once you start the engine, tighten this screw some more. Connect throttle clip (15) to upper handle.

4.Tilt blower back on handle and install front wheel bracket (51) over the three studs on lower front of blower housing. Secure with three 5/16-18 flange nuts (5).

5.Insert pneumatic wheel sleeve (53) in front pneumatic wheel (52). Install pneumatic wheel spacers (54) over the axle sleeve on both sides of wheel and install in front wheel bracket (51). Insert 3/8-16 x 5 1/4 axle bolt (50) through wheel bracket and axle sleeve. Secure with 3/8-16 axle nut (49).

WARNING DANGER

ALL LITTLE WONDER BLOWERS ARE SHIPPED WITHOUT OIL. WHEN FILLING OIL - USE SAE 30 OIL. REFER TO ENGINE MANUFACTURES INSTRUCTION MANUAL FOR PROPER ENGINE OPERATION INSTRUCTIONS.

Operating Instructions

Refer to Engine Manual for Engine Operation.

Little Wonder recommends using SAE 30 Oil. The use of multi-viscosity oil will result in high oil consumption and possible engine damage.

Leaves, thatch or other debris can be directed into windrows or piles, by simply maneuvering the unit and directing the flow of air accordingly.

Air flow can be directed to the side or front by the twoposition 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. The velocity is regulated by the throttle control.

Moving the deflector to the upper hole allows for a greater volume of air to be directed downward. Moving the deflector to the lower hole allows for a greater volume of air to be directed upward. To reduce windrowing or to blow over obstacle, point deflector upward.

Slight changes in deflector will have a big effect on air flow. Experiment until you find the best position for your needs.

For best performance, be sure engine recoil starter assembly, the blower intake and outlet areas are clear and free of leaves or other debris.

Maintenance Instructions

1.Keep all nuts, bolts, and screws tight.

2.Never store the Blower with fuel in its fuel tank

inside a building or in a confined space where fumes may reach an open flame or sparks.

3.Always refer to the instruction manual for important details if the product is to be stored for an extended period.

4.Engine - 4 cycle. (Refer to engine manufacturer's operating instructions for fuel recommendations and additional information.)

5.Tires - Tubeless. Inflate to air pressure of 30 P.S.I.

6.Labels should be inspected before each use. Replace damaged labels immediately.

Maintenance Instructions Con’t

Check oil level regularly. Be sure correct oil level is maintained. Check oil level after every 5 hours of operation, or daily, before starting engine. Use SAE 30 Oil. Change oil after first 5 hours of operation. Remove drain plug and drain oil while engine is warm. Replace drain plug. Remove oil fill plug and refill with new oil. Start and run engine at idle for 30 seconds. Stop engine. Wait 30 seconds and re-check oil level. If required, add oil to overflowing at oil fill plug.

Directions For Fan Removal:

(This procedure must be done by qualified Little Wonder dealer)

1.Remove intake guard and front panel.

2.Remove bolt and washer securing fan to engine crankshaft.

3.The fan has a 3/4-16 nut welded on the fan hub. Insert a 3/4-16 grade 5 bolt (or better) and jack or push the fan off the engine. (Little Wonder part #910515 pressure screw is recommended.) In some instances, it may be necessary to apply heat in area of fan hub as Loctite 242 has been used to secure the fan to the engine crank shaft. Be careful not to overheat.

4.Use a new bolt (P/N 910508 or P/N 910518) and Loctite 242 to insure a secure fit upon re-assembling.
