proper operation regularly.
Check bolts and screws for proper tightness at 
frequent intervals to keep the machine in safe 
working condition. Also, visually inspect machine 
for any damage. 
Before cleaning, repairing, or inspecting, stop the 
engine and make certain the tines and all moving 
parts have stopped. Disconnect the spark plug 
wire and ground it against the engine to prevent 
unintended starting.

instructions on off-season storage.
If the fuel tank has to be drained, do this outdoors.
Observe proper disposal laws and regulations for 
gas, oil, etc. to protect the environment.

the engine Thoroughly inspect the machine for any 
damage. Repair the damage before starting and 
operating. 
Disengage all clutch levers (if fitted) and stop engine 
before you leave the operating position (behind the 
handles). Wait until the tines come to a complete 
stop before unclogging the tines, making any adjust-
ments, or inspections.

underground utilities. Rotating tines can cause 
property damage or personal injury.
Do not overload machine capacity by attempting to 
till soil too deep at too fast of a rate. 
If the machine should start making an unusual noise 
or vibration, stop the engine, disconnect the spark 
plug wire and ground it against the engine. Inspect 
thoroughly for damage. Repair any damage before 
starting and operating.

and operating properly.

running.

by the manufacturer. Failure to do so can result in 
personal injury.
