Operation DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. • Always place gasoline containers on the ground away from your vehicle before filling.
Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. Filling the Fuel Tank 1. Shut the engine off. 2. Clean the area around the fuel tank cap and remove the cap (Figure 9). Note: The fuel tank cap contains a gauge which shows the fuel level.
length of time that the Start Relay Control can be active is 25 seconds from pressing the Rotate Right button. The Start button can be pressed multiple times while Engine Start Enable Condition is active. After the Engine Start Enable Condition expires, the Engine Start Enable Sequence must be performed again in order to energize the Start Relay Control with the Start button. 3. Rotate the engine ignition key to the “START” position and quickly release it to the “ON” position (Figure 11).
2. Let the engine idle for 20 seconds. 3. Press the STOP button on the remote control. 4. If leaving the machine, rotate the key to the OFF position and remove it from the engine (Figure 11). • To wake controller in time-out mode, turn the key switch to the OFF position and then turn the key switch to the start position momentarily (engine will turn over). • To avoid controller time-out during operation, use the remote control to rotate the chute or change the engine speed at least every 2.5 hours.
do not turn the machine around. Always back the tow vehicle slowly straight down the slope. DANGER TIP OVER CAN CAUSE SERIOUS INJURY OR DEATH. • Do not take an injury risk! When a person or pet appears unexpectedly in or near the operating area, stop operation. Careless operation, combined with terrain angles, ricochets, or improperly positioned guards can lead to thrown object injuries. Do not resume operation until the area is cleared. • NEVER operate on steep slopes.
Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 8 hours • Check the condition and the tension of the belt After the first 10 hours • Check the torque of the wheel lug nuts Before each use or daily • Check the engine oil level. • Clean the engine screen and the oil cooler. • Check the nozzle clamp and the nozzle guides Every 25 hours • Clean the foam air filter element and check the paper element for damage.
