The fuel gauge is part of the fuel-tank cap, and the gauge indicates the amount of fuel in the fuel tank (Figure 3).
Engine Controls Fuel-shutoff Valve The fuel-shut off valve (Figure 5) is located underneath the choke lever. Move the shutoff valve must to the On position before attempting to start the engine. Once you have finished using the machine and you have turned the engine off, move the fuel-shutoff valve to the Off position. Oil Alert System The oil alert system is designed to prevent engine damage caused by an insufficient amount of oil in the crankcase.
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. Note: Determine the left and right sides of the machine from the normal operating position. Important: Before operating, check the fuel and oil level, and remove debris from the machine. Also, ensure that the area is clear of people and debris.
1 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. 2 3 Filling the Fuel Tank Fuel tank capacity: 21.6 liters (5.7 US gallons). 1. Park the machine on a level surface and stop the engine. Allow the engine to cool. 5 2. Clean around the fuel tank cap and remove it. 4 3. Add unleaded gasoline to the fuel tank, until the level is just below the bottom of the filler neck.
Checking the Hydraulic Fluid Level CAUTION The hydraulic breather/filler cap is designed to pressurize the reservoir to 34 kPa (5 psi). Service Interval: Before each use or daily Loosen the cap slowly to avoid injury whenever adding oil or working on the hydraulic system. Use a wrench on the hex directly under the cap. Hydraulic fluid type: Mobil 424 Hydraulic Oil or equivalent The machines hydraulic tank is filled at the factory with approximately 28.4 liters (30 quarts) hydraulic fluid.
Note: The more you squeeze the handle, the faster the machine will travel. The more you squeeze the handle, the faster the machine will travel. 7. Turn the engine On/Off switch to the On position; refer to On/Off Switch (page 10). 8. Pull the recoil starter handle out until positive engagement results, then pull it vigorously to start the engine ( Recoil Starter Handle (page 10)). 6. When you release the speed control handle the machine will stop.
Parking the Machine Transporting the Machine Parking on a Grade When transporting the machine on a trailer, always use the following procedure: Important: Do not operate or drive the machine on roadways. Parking the machine on a grade should be avoided if possible. If the machine must be parked on a grade, park it at a right angle to the slope, apply the parking brake and block the wheels, if necessary. 1. Stop the engine and apply the parking brake. 2.
Lift the machine with a fork lift from the side or from the front (Figure 13 and Figure 14). Pull out on the platform release ring (Figure 15) and raise the standing platform to allow access to the fork pockets. 1 g019610 Figure 13 1. Rear fork pockets 1 g01961 1 Figure 14 1. Side fork pockets 1 g019606 Figure 15 1.
Using the Quick-release Tire Hubs The quick-release tire system allows quick removal of the outer machine tires. The quick-release system allows the machine to be converted from a 117 cm (46 inch) to a 91 cm (36 inch) wide machine without any special tools for hub removal. 1. Position the inner wheel of the machine over a 2x4 and apply the parking brake. 2. Remove the large tee bolt in the center of the wheel with a crow bar (Figure 16). 1 g019624 Figure 16 1. Tee bolt 3.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 50 hours • Change the engine oil. Before each use or daily • • • • • • Check the engine oil level. Check the hydraulic fluid level. Check service brake operation. Check parking brake operation. Remove debris from the machine.
