To ensure safe operation
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.
• If you run the engine in an area that is confined or even partially enclosed, the
air you breathe could contain a dangerous amount of exhaust gas. To keep
exhaust gas from building up, provide adequate ventilation.
• Replace faulty muffler.
• Do not operate the engine in a confined space where dangerous carbon
monoxide fumes can collect.
Operation on slope
• When tilling on slopes, keep the fuel tank less than half full to minimize fuel
spillage.
• Till across the slope (at equally spaced intervals) rather than up and down it.
• Be very careful when changing the direction of the tiller on a slope.
• Do not use the tiller on a slope of more than 10° (17%).
The maximum safe grade angle shown is for reference purpose only and should
be determined according to the type of the tool. Before starting the engine, check
that the tiller is not damaged and in good condition. For your safety and safety of
others, exercise extreme care when using the tiller on up or down hill.
