Before starting the machine each day, perform the following daily-check procedures:

• Checking the Engine-Oil Level

• Checking the Safety Interlock System

• Checking the Machine for Loose Hardware

Important: Ensure that the safety mechanisms on your machine are connected and in proper operating condition prior to operating your machine.

The safety interlock system is designed to prevent the engine from starting unless you engage the parking brake.

Important: For best results, use only clean, fresh fuel (less than 30 days old).

• Do not use gasoline containing methanol.

• Do not store fuel either in the fuel tank or fuel containers over the winter unless you use a fuel stabilizer.

• Do not add oil to gasoline.

Use a fuel stabilizer/conditioner in the machine to provide the following benefits:

Important: Do not use fuel additives containing methanol or ethanol.

Add the correct amount of fuel stabilizer/conditioner to the gasoline.

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.

Fuel tank capacity: 6.8 L (1.8 US gallons)

Note: Refueling the engine is difficult when using a larger refueling container such as a container with a 19 L (5 US gal) capacity.To make fueling the machine easier, use a 4 to 8 L (1 to 2 US gal) fuel container and a funnel.

1. Park the machine on a level surface and shut off the engine.

2. Allow the engine to cool.

3. Clean around the fuel-tank cap and remove it (Figure 17).

   

   Figure 17

4. Fill the tank with fuel (Figure 17) to within 6 to 13 mm (1/4 to 1/2 inch) from the top of the tank. Do not fill into the filler neck of the tank.

   Important: Do not fill the tank more than 6 mm (1/4 inch) from the top of the tank because the fuel needs room to expand.

5. Install the fuel-tank cap securely.

6. Wipe up any spilled fuel.

Use the spreader to disperses free-flowing granular substances such as grass seed, fertilizer, ice melt, etc. When you use the spreader, first fill the granular hopper, then apply the granular materials to the work site, and finally clean the hopper.

Important: When you use your spreader, thoroughly clean it at the end of the day.

• To ensure uniform application, broadcast the material in an overlapping pattern as shown in Figure 37.

  Note: The highest amount of material will dispense from the front of the hopper and less material from each side. You can adjust the distribution pattern to achieve the desired results.

• Watch for changes in the distribution pattern; unequal distribution may lead to striping.

Use the sprayer to disperse liquid herbicides, pesticides, fertilizers, and other substances. Before using the sprayer ensure that you have cleaned the tank, plumbing, and nozzles before adding any chemicals. When you use the sprayer, you first fill the spray tank, then apply the chemical solution to the work site, and then when you are finished spraying, clean the tank. It is important to complete all 3 of these steps to avoid damaging the sprayer. For example, Do not mix and add chemicals in the spray tank the night before and then spray in the morning. This could lead to separation of the chemicals and possible cause damage to components of the sprayer.

Important: When you use your sprayer, thoroughly clean it at the end of the day.
