ENGINE SWITCH
The engine switch (2) controls the ignition system. The switch
must be in the ON ( I ) position for the engine to start and run.
To stop, place the switch in the OFF ( O) position.
JUST ADD SAND™
Putting sand in the sand tank allows greater stability when
operating the cultivator, and also gives added weight to the
machine, allowing it to cultivate with less effort and vibration.
RECOIL STARTER
The recoil starter (3) is used for starting the engine.
PRIMER BULB
The primer bulb (7) pumps fuel from the fuel tank to the
carburettor. This is necessary only when starting a cold
engine or after refueling an engine that has run out of fuel.
CHOKE LEVER
The choke lever (4) opens and closes the choke valve in the
carburettor. The COLD START position enriches the fuel
mixture for starting a cold engine. The RUN position provides
the correct fuel mixture for normal operation after starting, or
for restarting a warm engine.
THROTTLE LEVER
The throttle lever (1) controls the rotation speed of the tines.
Completely engage the throttle lever while cultivating.

Insert pull pin (19) through holes in support rod, passing
through desired hole in drag bar, to secure drag bar at
desired height.
INSTALLING THE TINES ( Fig 5 ).
The cultivator has four tines (12) —two inner tines labeled B
and C, and two outer tines labeled A and D.
Lean the unit back on its wheels so that the handlebar
(13) rests on the ground.
Place tine C on the tine shaft (20) to the left of the gear
box (21). The stamped side of the tine should face away
from the gear box.
Place tine B on the tine shaft to the right of the gear box.
The stamped side of the tine should face away from the
gear box.
Place a felt washer (22) on each side of the tine shaft,
and slide to rest against the inner tines.
Place the outer tine labeled D on the left side of the tine
shaft. The stamped side should face in toward tine C.
Place the outer tine labeled A on the right side of the tine
shaft. The stamped side should face in toward tine B.
NOTE: When installed correctly, the angled edge (23) of
the tine blades should face the ground.
To secure the tines to the tine shaft, insert the hitch pin
(24) into the holes located on either side of the tine shaft.
NOTE: The unit will not operate properly if the tines are
installed incorrectly. If you notice a problem with the cultivating
operation of the unit, check for proper tine positioning.

MIXING THE FUEL
This product is powered by a 2-Stroke engine and requires
SUHPL[LQJSHWURODQG6WURNHRLO7KLVHQJLQHLVFHUWL¿HG
to operate on unleaded petrol intended for automotive use
with an octane rating of 91 ([R + M] / 2) or higher.
NOTE: We recommend you use Ryobi synthetic 2-Stroke
lubricant. Only use a quality synthetic 2-Stroke lubricant in
your cultivator to ensure top performance and engine longevity.
NOTE: Do not use automotive lubricant or 2-stroke outboard
lubricant. A synthetic 2-stroke lubricant containing a fuel
stabiliser is recommended.
NOTE: Do not use any type of pre-mixed petrol/lubricant
from fuel service stations, ethanol fuels or fuels containing
ethanol to avoid damage to your engine.

ADDING FUEL TO CULTIVATOR ( Fig 6 ).
When adding fuel to the cultivator, make sure the unit is sitting
on level ground and that the engine is not hot.
Clean area around fuel tank cap (25), if necessary.
Remove the fuel tank cap.
Insert a clean funnel into the fuel tank.
Slowly pour petrol/oil mixture into fuel tank.
NOTE: Fill tank no higher than 1.3 cm from top to allow
room for petrol expansion.
Reinstall the fuel cap. Clean up any spills.
ADDING SAND ( Fig 7 ).
The cultivator is equipped with a Just Add Sand™ weight
system, which improves the stability of the unit during operation
and helps you work with less effort and vibration.
Lift the lid (26) of the Just Add Sand™tank and remove.
Pour dry sand into the tank. The tank will hold approximately
6 kgs of sand.
NOTE: Do not pour sand into or onto the engine housing.
Replace Just Add Sand™lid.

Completely engage the throttle lever to begin tine rotation.
NOTE: The rotating tines help to pull the machine forward.
If the machine moves forward too quickly while wheels are in
position A (29) or B (30) with drag bar installed, push down
the handlebar to allow the drag bar to penetrate the soil and
slow the forward motion of the unit.
NOTE: Try to use a slower pace and shallow depth setting
when learning to use the unit and when cultivating on hard,
rough, or uneven ground.
Always operate the unit at full throttle when cultivating.
NOTE: Several passes over the same path may be required
to reach the desired depth. Do not try to dig too deeply in

STORING THE CULTIVATOR
The following steps should be taken before storing the
cultivator for the season.
Fuel Tank:
Drain the fuel tank completely if the cultivator will not be
used for more than two weeks.
Restart the engine to make sure no fuel is left in the car-
burettor. Run the engine until it stops. This helps prevent
gum deposits from forming inside the carburettor, which
subsequently can cause engine damage.
Spark Plug:
Disconnect spark plug wire and remove the spark plug.
Pour a teaspoon of clean, air-cooled, 2-stroke oil through
the spark-plug hole into the combustion chamber.
Leaving the spark plug out, pull the starter cord two or
three times to coat the inside of the cylinder wall.
Inspect spark plug, clean or replace as necessary.
Reinstall the spark plug, but leave the spark plug wire
disconnected.

Cultivator Body:
Clean dirt, grass, and other materials from the entire unit.
Wipe the tines with oil or spray them with silicone lubricant
to prevent rusting.
Oil the throttle cable and all visible moving parts. Do not
remove the engine cover.
Replace any badly worn or broken parts.
Store in an upright position in a clean, dry place. Store
with the handles in the extended position, or loosen handle
knobs and fold handles down. Do not allow throttle cable
to become pinched when lowering the handlebar.
Dispose any leftover fuel properly.
PREPARING FOR USE AFTER STORAGE
The following steps should be taken to prepare the cultivator
for use after it has been stored.
Unfold the handles into the upright position and secure by
tightening handlebar knobs. Do not allow throttle cable to
