To Push the Machine Warning 1. Disengage the power take off (PTO) and turn the ignition key to “OFF” to stop the engine. Move levers to neutral locked position and apply parking brake. Driving on street or roadway without turn signals, lights, reflective markings, or a slow moving vehicle emblem is dangerous and can lead to accidents causing personal injury. 2. Rotate the by-pass valves counterclockwise 1 turn to push. This allows hydraulic fluid to by-pass the pump enabling the wheels to turn (Fig.
Warning Warning Loading a unit onto a trailer or truck increases the possibility of backward tip–over and could cause serious injury or death. Unit could fall onto someone and cause serious injury or death. • Use extreme caution when operating unit on Z–Stand. • Use only for cleaning deck and removing blades. • Do not keep unit on Z–Stand for extended periods of time. • Always shut engine off and set parking brake before performing any maintenance to deck.
5. Start engine and put at half throttle. Cutting a Lawn for the First Time Note: For best results, place foot of stand into seams in sidewalks or into turf (Fig. 29). Cut grass slightly longer than normal to ensure the cutting height of the mower does not scalp any uneven ground. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than six inches tall, you may want to cut the lawn twice to ensure an acceptable quality of cut. 6. Drive onto stand.
Keep the Underside of the Mower Clean Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory. Blade Maintenance Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease.
Maintenance Recommended Maintenance Schedule Maintenance Service Interval After first use Each Use Maintenance Procedure • Hydraulic fluid—check level • Engine Oil—change • Hydraulic filter—change • • • • • Engine Oil—check level Safety System—check Mower Housing—clean Engine Coolant—check Engine Cooling System—clean1 Every 5 Hours • Cutting Blades—check • Blade Spindle Bearings—grease Every 25 Hours • • • • Hydraulic fluid—check level Chassis—grease1 Linkage bushings—oil1 Battery—check electrolyte
Caution If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition and disconnect the wire from the spark plug(s) before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug. Cutting Blades Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades.
Sharpening the Blades Warning MEASURE FROM CUTTING EDGE TO A LEVEL SURFACE When sharpening blade, pieces of blade could be thrown and cause serious injury. m–2539 Wear proper eye protection when sharpening blade. Figure 33 2. Rotate the opposite ends of the blades forward. Measure from a level surface to the cutting edge of the blades at the same position as in step 1 above. The difference between the dimensions obtained in steps 1 and 2 must not exceed 1/8” (3 mm).
4. Carefully remove filter from compartment (Fig. 37). 3 5 4 Cleaning Paper Elements 2 1. Paper Element A. Lightly tap the element on a flat surface to remove dust and dirt (Fig. 38). 1 3 4 B.
