Starting the Motor

1. Pivot the wheel (17) upwards until the locking engages on the intended recess.

2. Put the accelerator (16) into position.

•

A = Full throttle

•

B = Idle

•

C = Stop

3. Set the throttle lever to the position “A”. Start the motor using the recoil starter (1). To do this, first gently pull

until you feel resistance, then pull hard all the way. Repeat this operation until the motor starts up. If the

motor still does not start up after ten attempts, refer to the Troubleshooting

se

ction.

4. For operating the blades, withdraw the accelerator trigger lock (5) and pull the clutch handle (3) to start the

rotation of the blades. Keep the clutch handle (3) pushed downwards. Release the clutch to stop the blades.

Idle Speed

Set throttle control lever (16) to its “B” position to reduce stress on the engine when tilling is not being performed.

Lowering the engine speed to idle the engine will help extend the life of the engine, as well as conserve fuel and

reduce the noise level of the machine.

Shutting Down

Release tine clutch control lever (3) to neutral position (C) to stop the tines. To stop the engine, switch the

throttle lever to position (C).

Operating Speed

•

For normal tilling: Set the accelerator (16) to the rabbit icon for best tiller action.

•

For cultivating (Pos. A): The accelerator (16) should be set to control a slow walking speed (turtle icon) for

cultivating. (Pos. C)

Working Instructions

Depth Regulator

Besides depth regulator rod setting, variation of pressure on the handles also helps further control of tilling depth

and travel speed. A downward pressure on the handles will reduce the tilling depth and increase the forward

speed. An upward pressure on the handles will increase the working depth and reduce the forward speed.

Tilling

•

Tilling is digging in, turning over, and breaking up garden soil and preparing a seedbed for planting.

•

Best tilling depth is 100 to 150mm.

•

A tiller will also clear the soil of unwanted vegetation.

•

The decomposition of this vegetation matter enriches the soil.

•

Avoid tilling soil that is too dry as it will pulverize and produce a dust that will not hold water. Water a few

days before tilling. Also, tilling soil that is too wet will produce unsatisfactory clods. Wait a day or two after

heavy rain for the soil to dry.

•

Better growth will be obtained if an area is tilled properly and used soon after tilling to preserve the moisture

content.

BT-889 4-Stroke Tiller

•

The type of soil and working conditions will determine the actual setting of the tilling depth. In some soils, the

desired depth is reached by first passing over garden. In other soils, the desired depth is obtained by going

over the garden two or three times. In later case, the depth regulator rod should be lowered before each

succeeding pass over the garden. Passes should be made across the length and width of the garden

alternately.

•

Do not try to dig too deeply in the first pass. If the machine jumps or bucks, allow the unit to move forward at

a lightly faster rate.

•

If the tiller stops forward motion and tries to dig in one spot, rock the handles from side to side to start it

moving forward again.

•

Rocks which are turned up should be removed from the garden area.

Cultivating

Cultivating is loosening or digging around growing plants to disrupt weeds and aerate soil. Less than 50mm

depth is always desirable.

Maintenance

Keeping your tiller in top running condition will prolong its life, and help you obtain optimum

performance whenever you wish to till your garden.

Cleaning Tine Area

Clean the tiller underside of the tine shield after each use. The dirt washes off tines easier if rinsed off

immediately instead of after it dries.

1. Turn OFF engine. Engine must be cool.

2. Set to “C” position and remove spark plug wire from spark plug and secure.

3. Remove all vegetation, string, wire, and other materials that may have accumulated to the axle between the

inside set of tines and the seal on the transmission housing.

Checking the Clutch

1. As clutch wears out, the same lever could have a wider opening, being so uneasy to use. This means that it

is necessary to adjust the cable, setting clutch lever on its original position acting on the adjustment device

and on counter nut.

2. Always towel dry the tiller afterwards and apply a light coat of oil or silicone to prevent rusting or water

damage.

3. Replace spark plug wire.

ATTENTION! Never use a pressure washer to clean your tiller. Water can penetrate tight areas of

the tiller and its transmission case and cause damage to spindles, gears, bearings, or the

engine. The use of pressure washers will result in shortened life and reduce serviceability.

Maintaining the Spark Plug

•

You must inspect the spark plug after every 50 hours of actual operation.

•

Check the colour of any deposits that have accumulated on the end of the spark plug, it should be light

brown.

BT-889 4-Stroke Tiller

•

Remove any deposits with a stiff brush, preferably a brass-wire brush. Check the gap between the spark

plug electrodes and adjust it if necessary. This gap must be between 0.7 and 0.8 mm.

Replacing the Motor Oil

Remove / refill all oil with a syphon after every 20 hours of use.

Air Filter

You must examine the condition of the air filter and clean it after every 50 hours of actual use or every 3 months.

1. Hold the air filter while unscrewing the wing nut and remove the air filter.

2. To clean it, use an environmentally friendly water-based de-greasing product.

3. Let the air filter dry completely, re-assemble it and put on its cover.

CAUTION! Never run the motor without its air filter.

Storage

If the tiller will not be used for a period longer than 30 days, follow the steps below to prepare your tiller for

storage.

1. Drain the fuel tank completely. Stored fuel containing ethanol or MTBE can start to go stale in 30 days. Stale

fuel has a high plastic content and can clog the carburettor and restrict fuel flow.

2. Start the engine and allow it to run until it stops. This ensures no fuel is left in the carburettor. Run the engine

until it stops. This helps prevent plastic deposits from forming inside the carburettor and possible engine

damage.

3. While the engine is still warm, drain the oil from the engine. Refill with fresh oil of the grade recommended in

the Engine Manual.

4. Allow the engine to cool. Remove the spark plug and put 30ml of high-quality motor oil into the cylinder. Pull

the starter rope slowly to distribute the oil. Replace the spark plug.

ATTENTION! Remove the spark plug and drain all the oil from the cylinder before attempting to start

the unit after storage.

5. Use a clean cloth to clean off the outside of the tiller and to keep the air vents free of obstructions.

ATTENTION! Do not use strong detergents or petroleum-based cleaners when cleaning plastic parts.

Chemicals can damage plastics.

6. Inspect for any loose or damaged parts. Repair or replace damaged parts and tighten loose screws, nuts or

bolts.

7. Remove the tines. Clean and apply oil to the tines and tine shafts to prevent rusting. Mount the tines onto the

tine shafts.

8. Coat the wheel axles lightly with oil. Oil the throttle cables and all visible moving parts. Do not remove the

engine cover.

9. Store your tiller in upright position in a clean, dry building that has good ventilation.

ATTENTION! Do not store tiller with fuel in a non-ventilated area where fuel fumes may reach flame,

sparks, pilot lights or any ignition sources. Use only approved fuel containers.
