• Stop equipment and inspect blades after striking objects or if an abnormal vibration occurs. Make necessary repairs before resuming operations. Preparation • Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Only use accessories and attachments approved by the manufacturer. • Keep hands and feet away from the cutting units. • Look behind and down before backing up to be sure of a clear path.
• Before operating a machine with ROPS (roll over protection) be certain the seat belts are attached to prevent the seat from pivoting forward. • Charge batteries in an open well ventilated area, away from spark and flames. Unplug charger before connecting or disconnecting from battery. Wear protective clothing and use insulated tools. • Check carefully for overhead clearances (i.e. branches, doorways, electrical wires) before driving under any objects and do not contact them.
• Do not try to stabilize the machine by putting your foot on the ground. • Do not use a grass catcher on steep slopes. Heavy grass bags could cause loss of control or overturn the machine. Service • Never store the machine or fuel container inside where there is an open flame, such as near a water heater or furnace. • Keep nuts and bolts tight, especially the blade attachment bolts. Keep equipment in good condition. • Never tamper with safety devices.

Checking the Hydraulic Fluid 4. Slowly pour electrolyte into each battery cell until the level is up to the upper line (Fig. 3) on the battery case. Check the hydraulic fluid level before the engine is first started. Important Do not overfill the battery because electrolyte (sulfuric acid) can cause severe corrosion and damage to the chassis. Refer to Checking the Hydraulic Fluid on page 42. 5. Wait five to ten minutes after filling the battery cells.

Understanding the Safety Interlock System Driving Forward or Backward The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the fast position for best attachment performance. Always operate in the full throttle position when operating attachments. The safety interlock system is designed to prevent the engine from starting unless: • The parking brake is set. • The power take off (PTO) is disengaged or off.
To turn move the motion control lever toward neutral, on the side you want to turn toward (Fig. 13). To slow or stop move the motion control levers to neutral. 1 Stopping the Machine 2 To stop the machine, move the motion control levers to neutral, disengage the power take off (PTO), and turn the ignition key to off. Also set the parking brake when you leave the machine; refer to Setting the Parking Brake, page 15. Remember to remove the key from the ignition switch. m–3280 Figure 15 1.
Caution The mower deck is heavy and could injure someone while raising or lowering the deck. • Use caution when raising or or lowering deck. 1 m–4863 Raising the Mower Figure 18 1.

Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval After first use Maintenance Procedure • Check the hydraulic fluid level. • Change the oil. • Change the hydraulic filter. Each use • • • • • Check the oil level.1 Check the safety system. Clean the hopper. Clean the mower housing. Clean the cooling systems. Every 5 hours • • • • • • • Check the hydraulic fluid level.
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(s) from the spark plug(s) before you do any maintenance. Set the wire(s) aside so that it does not accidentally contact the spark plug(s). Servicing the Cutting Blades Inspecting the Blades To ensure a superior quality of cut, keep the blades sharp.
3 mm (1/8 in.), the blade is bent and must be replaced. Refer to Removing the Blades, and Installing the Blades on page 29. Front Front 1 M–4852 Figure 43 1. Cutting edge Note: Use anti-seize lubricant on spindle and keyway before installing blade retainer. 1. Install the key in the retainer and install blade retainer to spindle (Fig. 44). 2. Install the blade, spacer, washer, and retainer bolt to spindle (Fig. 44). M–4852 Figure 42 3. Torque the retainer bolt to 115–140 N⋅m (85–110 ft.-lb.).
Sharpening the Blades 1. Check the tire pressure on both deck and traction unit. 1. Use a file to sharpen the cutting edge at both ends of the blade (Fig. 45). Maintain the original angle. The blade retains its balance if the same amount of material is removed from both cutting edges. 2. Set the height-of-cut to the 2-1/2 in. position following the height-of-cut decal. 3. With the machine on level surface, position one blade front-to-rear (Fig. 47).

Do this to the corresponding side that needs adjustment.
The plunger inside the gauge canister will change to red when the air cleaner element becomes dirty and restricted. When it changes red, air cleaner maintenance is required. 1. Start by visually checking the condition of the primary element. If the element is visually dirty, replace the primary element. Do not attempt to clean it. 1 2. Reset the gauge by depressing the button in the bottom of the canister until the plunger returns to the lowest point (Fig. 53). 3.
USE THESE SAE VISCOSITY OILS Cleaning the Primary Filter Blow compressed air from the inside to the outside of the primary filter. 10W–30 Important Do not exceed 685.5 kPa (100 psi) and keep the hose at least 5cm (2 in.) from the filter. 5W–20, 5W–30 Installing the Filters 1. If installing new filters, check each filter for shipping damage. Do not use a damaged filter. –20 5F 0 2. If the safety filter is being replaced, carefully slide it into the filter body (Fig. 55).
Changing the Engine Oil Changing the Engine Oil Filter 1. Start the engine and let it run five minutes. This warms the oil so it drains better. Replace the oil filter after first 8 hours of use. Replace the oil filter every 200 hours or every other oil change. 2. Park the machine so that the drain side is slightly lower than the opposite side to assure the oil drains completely. Then disengage the power take off (PTO), set the parking brake, and turn the ignition key to off. Remove the key.
Removing the Spark Plugs 2 1. Disengage the power take off (PTO), set the parking brake, and turn the ignition key to off. Remove the key. 3 1 2. Pull the wire(s) off the spark plug(s) (Fig. 59). Now clean around the spark plug(s) to prevent dirt from falling into the engine and potentially causing damage. 0.030 in. (0.76 mm) 3. Remove the spark plug(s) and metal washer. m–3215 Figure 60 2 1.

Uneven tire pressure can cause uneven cut.
Replacing the Hydraulic Filter 3. Remove cap from filler neck. Look inside to check if there is fluid in the reservoir (Fig. 81). Change the hydraulic filter: 4. If there is no fluid, add fluid to reservoir approximately a 6mm (1/4 in.) below the top of baffle. • After the first 8 operating hours • After every 200 operating hours 5. Run the machine 15 minutes to allow any air to purge out of the system and warm fluid. 1.
11. Recheck level while fluid is warm. Add fluid to raise level to top of the baffle, if required. Do not over fill. Warning Hydraulic fluid escaping under pressure can penetrate skin and cause injury. 1 • If hydraulic fluid is injected into the skin it must be surgically removed within a few hours by a doctor familiar with this type of injury. Gangrene may result if this is not done. • Keep body and hands away from pin hole leaks or nozzles that eject high pressure hydraulic fluid.
