2 Before Operating Checking the Engine Oil 1 The engine uses any high-quality detergent oil having the American Petroleum Institute (API) service classification of CD, CE, CF or CF-4 or CG-4 or higher. The recommended viscosity (weight) is SAE 10W30. The engine is shipped with 3.5 quarts (w/ filter) (3.3 l) of oil in the crankcase; however, the level of oil must be checked before and after the engine is first started. Figure 23 1. Position the machine on a level surface. 1. Dipstick 2.
2. Remove the fuel tank cap. The cooling system is filled with a 50/50 solution of water and permanent ethylene glycol antifreeze. Check the level of the coolant at the beginning of each day before starting the engine. Danger Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage. Caution If the engine has been running, the pressurized, hot coolant can escape and cause burns.

To set the reel speed, rotate the knob (Fig. 37) until the indicator arrows are in line with the number designating desired setting. 1 4. Sit on the seat, move the traction pedal to Neutral, move the functional control lever to Neutral, and engage the parking brake. Start the engine. Release the parking brake, move the functional control lever to mow, and rise from the seat.
Important Familiarize yourself with the fact that the No. 1 cutting unit reel is delayed when lowering and raising, therefore, you should practice to try to gain the required timing necessary to minimize the cleanup mowing operation. 4 2 3 1 3. Overlap a minimal amount with the previous cut on return passes. To assist in maintaining a straight line across the green and to keep the machine an equal distance from the edge of the previous cut, establish an imaginary sight line approximately 6 to 10 ft. (1.
Towing the Traction Unit Important The machine should never be stopped on a green with the cutting unit reels operating as damage to the turf may result. Stopping on a wet green with the machine may leave marks or indentations from the wheels. In case of an emergency, the machine can be towed for a short distance (less than 1/4 mile [0.4 km]). However, we do not recommend this as a standard procedure. 6. Finish cutting the green by mowing the outer periphery.
