OPERATING SAFELY

IN GENERAL

– Use extra care when loading or unloading the

machine into a trailer or truck.

– Do not run the engine in an enclosed area where

dangerous carbon monoxide fumes can collect.

– Never leave a running machine unattended.

Always stop engine when leaving the operator position.

– Do not blow towards people, cars, windows, or

other items which could be injured or damaged by the blown debris.

– Keep hands away from the blower air intake and

outlet.

STARTING

– Start according to instructions in this manual or

on the machine.

– Do not change engine governor settings or

overspeed the engine. Operating the engine

at excessive speed can increase the hazard of

personal injury.

– Use extreme caution when reversing.

OPERATING ON SLOPES

USE EXTRA CARE WHEN OPERATING ON SLOPES.

EVALUATE THE RISKS INVOLVED BEFORE OPER-

ATING ON A SLOPE

- Slopes are a major factor related to slip and fall accidents that sometimes lead to severe injury or death. All slopes require extra caution.

INTERRUPTING OPERATION

- Before leaving the operator's position:

- Park on level ground.

- Release the traction drive bail.

- Shut off the engine.

- Stop the engine, and wait until the fan stops moving:

- before refueling;

- Stop the engine, and disconnect the spark plug wire(s):

- before clearing blockages;

- before checking, cleaning or working on the

machine;

- if the machine begins to vibrate abnormally:

shut off machine immediately. Inspect

and have repairs made as needed before restarting;

- except for repairs or adjustments as specically

noted, such as for carburetor adjustment,

where the engine must be running. Keep

hands and feet clear of moving parts in these circumstances.

- Allow the fan to come to a complete stop when stopping operation to clear blockages, unclog, inspect the machine, do maintenance or repair.

- Reduce the throttle setting during engine shut-

down and, if the engine is provided with a shutoff valve, turn the fuel off at the conclusion of operation.

- Do not operate on slopes if uneasy or uncertain.

Ultimate responsibility for safe operation on slopes

rests with the operator.

- Do not operate on steep slopes. Poor footing could cause a slip and fall accident.

- Keep all movement on slopes slow and gradual.

- Do not operate near drop-offs, ditches or embank-

ments. You could lose your footing or balance or

drive the machine off the edge.

- Do not turn on slopes unless necessary, and then turn slowly and downhill when possible.

- Be sure of your footing on slopes.

- Watch for holes, ruts, bumps, rocks and other hid-

den objects. Uneven terrain could cause a slip and

fall accident. Tall grass can hide objects.

MAINTENANCE SAFETY In general

- Maintain machine according to manufacturer's schedule and instructions for maximum safety and best results.

- Park machine on level ground.

- Never allow untrained personnel to service machine.

- Guards should only be removed by a qualied

technician for maintenance or service.

- Adjust or repair only after the engine has been stopped and the fan has stopped moving.

- Disconnect spark plug wire(s) before doing any

maintenance.

- Replace parts if worn, damaged or faulty. For best results, always replace with parts

recommended by the manufacturer.

- Do not dismantle the machine without releasing or restraining forces which may cause parts to move suddenly.

- Provide adequate support, e.g. jack stands for lifted machine or parts if working beneath.

- Do not put hands or feet near or under rotating parts.

- Clean up spilled oil or fuel thoroughly.

- Replace faulty mufers.

- To reduce re hazards, keep the engine, muf-

er, and fuel storage area free of grass, leaves,

debris buildup or grease.

- When refueling or checking fuel level:

- Stop the engine and allow to cool;

- Do not smoke;

- Refuel outdoors only;

- Use a funnel;

- Do not overll;

- If fuel is spilled, do not attempt to start the

engine until the spill is cleaned up and vapors have cleared.

- Replace caps on fuel containers and tanks

securely.

Sparks from static electricity can start res or cause explosions. Flowing fuel can generate static

electricity. To prevent static electricity sparks:

- Keep containers electrically grounded. Do not ll

containers in a vehicle or on a truck or trailer bed

with a plastic liner. Fill containers on the ground

away from the vehicle.

- When practical, remove petrol (gasoline) powered equipment from the truck or trailer

and refuel it on the ground. If equipment must

be refueled on the truck or trailer, refuel from a portable container rather than a dispenser

nozzle.

- Keep the dispenser nozzle in contact with the rim

of the fuel tank or container opening until fueling

is complete. Do not use a nozzle lock-open

device.

- If fuel is spilled on clothing change it immediately.

STORAGE SAFETY

Fans

Do not straighten or weld fans. Replace dam-

aged or failed fans..

Fuel

- Gasoline (petrol)) and die-

sel fuels are ammable;

gasoline (petrol) vapors

are explosive. Use extra

care when handling.

- Store only in containers

specically designed for

fuel.

WARNING

- Stop the engine and allow to cool before storing.

- Drain the fuel tank outdoors only.

- Store fuel in an approved container in a cool, dry

place.

- Keep the machine and fuel containers in a locked

storage place to prevent tampering and to keep children from playing with them.

- Do not store the machine or fuel container near an

open ame, spark, or appliance, such as a water

heater, or a pilot light.

- Keep petrol (gasoline) storage area free of grass,

leaves and excessive grease to reduce re haz-

ard.

- Clean grass and debris from cutting units, drives, mufers and engine to help prevent res.

OPERATION

LITTLE

WONDER

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.

3 Fill the fuel tank with good quality, clean, unleaded

regular gasoline (petrol). Use a funnel to avoid

spilling.

OPERATING INSTRUCTIONS

Air ow can be directed to the side or front by the two-position vertical deector. 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 deector

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 deector upward.

easily if it is moved while the clutch bail is released, particularly if going from forward to reverse.

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.

To stop the engine, move the throttle control to the slow position and switch the engine off.

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 possibil-

ity of ooding should any dirt get under the carburetor oat needle. Leaving the valve open can allow severe ooding which may ruin the engine by diluting the oil.

To avoid blowing in an area, close deector and

reduce throttle setting.

Slight changes in deector position will have a big effect on air ow. Experiment until you nd 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

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 rst 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 ll plug and ll with new oil. See engine manual for oil specications.

MAINTENANCE

Lubricate chains every 40 hours or weekly, whichever

comes rst. Use a teon 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 difcult. A teon 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.

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.

remove it from the handle to get enough slack. Move the speed control lever to neutral.

2. Drain the oil and fuel so the machine may be tipped.

3. Remove the front wheel bracket and inlet cover. Tip

the machine forward onto the fan housing to gain access to the bottom side.

4. Remove bottom cover.

of the trunnion link rod B. Remove the trunnion link rod.

6. Loosen and back off the setscrews C on both bearing adaptors on the hex shaft.

7. Remove the bolts D holding the bearings on each end of the hex shaft to the engine deck.

DIFFERENTIAL REPLACEMENT

1. If the shafts are removed or the differential needs

to be replaced, the equivalent of one or two pumps of Bentonite (waterproof) grease must be put in the space where the shafts come together.

2. Install the shaft with the hollow end, then put the

grease in the differential cavity and install the

second shaft. (Figure 5)

deck. Remove the shaft assembly from the engine

deck.

9. Slide the bearing F off the trunnion end of the shaft and remove the trunnion.

10. Replace the driven disc.

11. Reinstall in the reverse order. Be sure to put the belt around the hex shaft. Check the installation for

STORAGE

STORAGE / TORQUE SPECIFICATIONS

To prevent possible explosion or ignition of vaporized

fuel, do not store equipment with fuel in tank or

carburetor in an enclosure with open ame (for example,

a furnace or water heater pilot).

Before the equipment is put into storage for any period exceeding 30 days.

1. Drain all fuel from the fuel tank and fuel lines.

2. Start the engine and run until all the fuel is used

from the carburetor oat bowl and the engine

stops.

3. While the engine is still warm, drain the crankcase oil and replace with the proper weight oil corresponding to the season the equipment will be next used.

4. Remove the spark plug and squirt a small amount

of engine oil into the cylinder. Slowly pull the starter a few times to distribute oil in the cylinder and reinstall the spark plug.

5. Top off if necessary. See engine manual for details.

To put the equipment into service after an extended period of storage.

1. Check for loose parts and tighten if necessary.

2. Fill the fuel tank and then check the engine oil

level.

3. Start the engine and check for fuel leaks. Repair

any leaks before operating the unit.
