manual abstract


If it is not possible to use one full width ramp, use enough individual ramps to simulate a full width continuous ramp. Ramp should be long enough so that the angles between the ramp and the ground and the ramp and the trailer or truck do not exceed 15°. A steeper angle may cause mower deck components to get caught as the unit moves from ramp to trailer or truck. Steeper angles may also cause the unit to tip backward. If loading on or near a slope, position the trailer or truck so it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp angle. The trailer or truck should be as level as possible. 27 Maintenance Maintenance Note: Determine the left and right sides of the machine from the normal operating position. WARNING While maintenance or adjustments are beingmade, someone could start the engine. Accidental starting of the engine couldseriously injure you or other bystanders. Remove the key from the ignition switch, engage parking brake, and pull the wire(s) off the spark plug(s) before you do anymaintenance. Also push the wire(s) asideso it does not accidentally contact the sparkplug(s). WARNING The engine can become very hot. Touchinga hot engine can cause severe burns. Allow the engine to cool completely beforeservice or making repairs around the engine area. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 5 hours • Change the engine oil. After the first 100 hours • Check the wheel hub slotted nut torque specifications. • Check the wheel lug nuts. • Check the park brake adjustment. Before each use or daily • Check the engine oil level. • Check the mower blades. • Check the safety interlock system. • Check the rollover protections systems (roll bar) knobs. • Check the seat belt. • Check for loose hardware. • Clean the engine and exhaust system area. • Clean the hydro fan cooling guards. • Clean the grass and debris build-up from the machine and cutting deck. • Clean the grass build-up from under the cutting deck. Every 50 hours • Check the hydraulic oil level. • Check the tire pressures. • Check the condition of the belts. • Check spark arrester (if equipped). Every 100 hours • Change the engine oil. (May need more often under severe conditions.) • Lubricate the deck lift pivots. • Remove the engine shrouds and clean the cooling fins. Every 200 hours • Service the air cleaner. (May need more often under severe conditions. See the Engine Owner’s Manual for additional information.) • Lubricate the brake handle pivot. • Check the spark plugs. 28 Maintenance Maintenance Service Interval Maintenance Procedure Every 500 hours • Change the hydraulic filter and fluid. • Check the wheel hub slotted nut torque specifications. • Check the wheel lug nuts. • Check the park brake adjustment. Yearly • Grease the deck and pump idler pivots. • Grease the front caster pivots. Periodic Maintenance Check Engine Oil Level Service Interval: Before each use or daily 1. Stop engine and wait for all moving parts to stop. Make sure unit is on a level surface. 2. Check with engine cold. 3. Clean area around dipstick. Remove dipstick and wipe oil off. Reinsert the dipstick according to the engine manufacturer’s recommendations. Remove the dipstick and read the oil level. 4. If the oil level is low, wipe off the area around the oil fill cap, remove cap and fill to the “FULL” mark on the dipstick. Use oil as specified in Engine Owner’s Manual. Do Not overfill. Important: Do Not operate the engine with theoil level below the “LOW” (or “ADD”) mark onthe dipstick, or over the “FULL” mark. Check Battery Charge Service Interval: As required WARNING CALIFORNIA Proposition 65 Warning Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. Allowing batteries to stand for an extended period of time without recharging them will result in reduced performance and service life. To preserve optimum 29 battery performance and life, recharge batteries in storage when the open circuit voltage drops to 12.4 volts. Note: To prevent damage due to freezing, battery should be fully charged before putting away for winter storage. Check the voltage of the battery with a digital voltmeter or with the message display. If the ignition key is turned to the “on” position for a few seconds, the battery voltage will be displayed in the area where the hours are normally displayed. Locate the voltage reading of the battery in the table and charge the battery for the recommended time interval to bring the charge up to a full charge of 12.6 volts or greater. Important: Make sure the negative batterycables are disconnected and the battery chargerused for charging the battery has an output of16 volts and 7 amps or less to avoid damagingthe battery (see chart for recommended chargersettings).
