ENGINE SAFETY PRECAUTIONS
If your product comes with a separate engine manual, be
sure to read and follow all safety and warning precautions
outlined there, in addition to any in this manual.
Preventing Carbon Monoxide Poisoning
• Always start and run engine outdoors. Do not start
or run engine in an enclosed area, even if doors or
windows are open.
• Never try to ventilate engine exhaust indoors. Carbon
monoxide can reach dangerous levels very quickly.
• Never run engine outdoors where exhaust fumes may
be pulled into a building.
• Never run engine outdoors in a poorly ventilated area
where the exhaust fumes may be trapped and not
easily taken away. (Examples include: in a large hole
or areas where hills surround your working area.)
• Never run engine in an enclosed or partially enclosed
area. (Examples include: buildings that are enclosed
on one or more sides, under tents, car ports or
basements.)
• Always run the engine with the exhaust and muer
pointed in the direction away from the operator.
• Never point the exhaust muer towards anyone.
People should always be many feet away from the
operation of the engine and its attachments.
• Do not change the engine governor settings or over-
speed the engine.
Gasoline Fires and Handling Fuel Safely
Use extra care in handling gasoline and other fuels. They are
ammable and vapors are explosive.
• When storing extra fuel be sure that it is in an
appropriate container and away from any re hazards.
• Prevent re and explosion caused by static electric
discharge. Use only nonmetal, portable fuel
containers approved by the Underwriter’s Laboratory
(U.L.) or the American Society for Testing & Materials
(ASTM).
• Never remove the fuel cap or add fuel with the engine
running. Stop engine and allow to cool before lling.
• Do not smoke.
• Never drain fuel from engine in an enclosed area.
• Always ll fuel tank outside in a well ventilated area.
Never ll your fuel tank with fuel indoors. (Examples
include: basement, garage, barn, shed, house, porch,
etc.) Never ll tank near appliances with pilot lights,
heaters, or other ignition sources. If the fuel has to be
drained, this should be done outdoors. The drained
fuel should be stored in a container specically
designed for fuel storage or it should be disposed of
carefully.
• Always wipe up excess (spilled) fuel from engine
before starting. Clean up spilled fuel immediately.
If fuel is spilled, do not start the engine but move
product and fuel container from area. Clean up spilled
fuel and allow to evaporate and dry after wiping and
before starting.
• Allow fuel fumes/vapors to escape from the area
before starting engine.
• Test the fuel cap for proper installation before starting
and using engine.
• Always run the engine with fuel cap properly installed
on the engine.
• Never smoke while relling engine fuel tank.
• Do not store engine with fuel in fuel tank indoors. Fuel
and fuel vapors are highly explosive.
Preparation
• Dress appropriately when operating the tiller. Always
wear sturdy footwear. Never wear sandals, sneakers
or open shoes, and never operate the tiller with
bare feet. Do not wear loose clothing that might get
caught in moving parts.
• Carefully inspect the area to be tilled and remove
all foreign objects. Do not till above underground
water lines, gas lines, electric cables, or pipes. Do not
operate the tiller in soil with large rocks and foreign
objects which can damage the equipment.
• Disengage all clutches and leave control lever in the
neutral position before starting the engine.

FEATURES
The advantage of the CountyLine® gear drive front tine rototiller, over other front tine tillers, is the exclusive hinged tail mount,
wheel and drag stake assembly. This feature gives the tiller its stability and versatility. For easy transport and quick turning in the
garden, fold the wheels under the engine. During operation, the wheels unfold back and the drag stake folds down. The long
length between the tines and the drag stake make this the most comfortable handling front tine tiller on the market.
