NOTE
To prevent possible fire, never fill fuel tank while the engine is running. Always be sure gasoline
container and machine are grounded before dispensing gas. This can be done by permanently
attaching an insulated wire with a battery clip on the end to the gasoline container.
WARNING
When the machine has been stored in below freezing temperatures, run the engine at not over ½
throttle with the machine standing still for 5-10 minutes to warm the engine and hydraulic oil.
