Thrown Object Hazard
Objects hit by the rotating tines can be thrown from the tiller
with great force and may cause severe injury.
1. Before tilling, clear the tilling area of sticks, large stones,
wire, glass etc.
2. Pieces thrown from worn or damaged-tines can cause
serious injury. Always inspect the tines before using the
tiller.
Fire and Burn Hazard
Gasoline is extremely flammable and gasoline vapor can
explode.
Use extreme care when handing gasoline. Keep gasoline out
of reach of children.
1. Refuel in a well-ventilated area with the engine stopped.
2. Allow the engine to cool before refueling. Fuel vapor or
spilled fuel may be ignited.
3. The engine and exhaust system becomes very hot during
operation and remains hot after stopping. Touching them
can cause burn injuries or some materials burn.
4. Avoid touching a hot engine or exhaust system.
5. Allow the engine to cool before performing maintenance or
storing the tiller indoors.
Carbon Monoxide Poisoning Hazard
Exhaust contains poisonous carbon monoxide a colorless and
odorless gas. Breathing exhaust can cause loss of
consciousness and may lead to death.
Operation on Slope
1. When tilling on slopes, keep the fuel tank with less than half
oil to minimize fuel spillage.
2. When the tiller walks across the slope, put your effort
evenly while walking up and down the slope.

ORIGINAL INSTRUCTIONS

3. Be very careful when changing the direction of the tiller on
a slope.
4. Do not use the tiller on a slope of more than 10°.
5. The maximum safe grade angle shown is for reference only

b) Hot starting
- Exactly the same process as from cold except keep the
choke in the run position. With the engine running and the
tines off the ground, pull up the throttle control lever to
increase the engine speed.
d. Use
Hold both handlebar grips firmly, slowly lower the cultivator
until the tines make contact with the ground, As the tines
rotate on the soil, begin to pull back on the tiller so that the
tines can penetrate the ground. Once the ground has been

3. lf the tines gets damaged, then replace or repair
immediately.
WARNING: To prevent serious injury, never perform
maintenance or repairs to a hot engine.
CLEANING THE AIR FILTER
Clean and re-oil the air filter every ten hours of operation.
It is vitally important item to maintain.
Remove the sponge filter from inside.
Wash the filter in detergent and water (Fig. 10). Rinse the filter
thoroughly. Squeeze out excess water and allow it to dry
completely.
Apply enough SAE 3D oil to lightly coat the filter (rig. 11).
Squeeze the filter to spread and remove extra oil (Fig. 11).
Replace the air filter and cover and securing screw.
NOTE: Operating the machine without the air filter and cover
assembly will VOID the warranty.
ADJUSTING IDLE SPEED
After checking and cleaning the air filter if necessary, start the
engine and let it run for 2-3 minutes to warm up.

ORIGINAL INSTRUCTIONS
17
Release the throttle lever and allow the engine to idle. If the
engine cuts out (will not idle), turn the adjuster clockwise l/8th
of a turn at a time until the engine idles smoothly.
NOTE: Tines must not be rotating on idle. If they do, turn the
adjustment screw anti-clockwise a tiny amount.
Replacing the Spark Plug
a) Use a champion RDJ7Y spark plug (or equivalent). The
correct air gap is 0.020in (0.5mm). Remove the plug after
every 25 hours of operation to check its condition.
b) Stop the engine and allow it to cool. Grasp the plug cap
firmly and pull the cap from the spark plug. Clean dirt from
around the spark plug. Remove the spark plug from the
cylinder head by turnings 5/8’’ socket (supplied)
counter-clockwise.
c) Set the gap at 0.020 in (0.5mm) using a feeler gauge.
d) Clean and replace the spark plug finger-tight and take care
not to cross the thread in the cylinder head.
e) Tighten using the wrench taking care not to over-tighten.
f) On no account allow dirt to enter the cylinder when the spark
plug is removed. We suggest filling the plughole using a small
piece of clean rag. Do not use tissue as this may tear and
enter the cylinder.
STORAGE
Allow the engine to cool before storing. To be stored in a
well-ventilated and dry area that out of the reach of children.
Long Term Storage
a) Drain any fuel left in the tank into a container and dispose of
considering local bylaws.

ORIGINAL INSTRUCTIONS

b) Start and run the engine until it stalls. This ensures all fuel
has been used from the carburetor.
c) Allow the engine to cool and remove the spark plug.
d) Put 30ml of high quality motor oil into the cylinder. Slowly
pull the starter to distribute the oil.
e) Re-install the spark plug.
NOTE:
When re-starting after prolonged storage, be sure to drain all
the oil out from the cylinder first!
