Safety • Refuel outdoors only and do not smoke while refueling. • Add fuel before starting the engine. Never remove the cap of the fuel tank or add gasoline while the engine is running or when the engine is hot. This machine has been designed in accordance with EN ISO 5395:2013.
• Remember there is no such thing as a safe slope. Travel • • • • • • • • • • • • Disengage drive to attachments when transporting or not on grass slopes requires particular care. To guard against overturning: – do not stop or start suddenly when going up or downhill; – machine speeds should be kept low on slopes and during tight turns; – stay alert for humps and hollows and other hidden hazards; – never mow across the face of the slope, unless the lawn mower is designed for this purpose.

Using the Safety Interlock System Service Interval: Before each use or daily CAUTION If the safety interlock switches are disconnected or damaged, the machine could operate unexpectedly, causing personal injury. • Do not tamper with the interlock switches. • Check the operation of the interlock switches daily and replace any damaged switches before operating the machine. Figure 12 • Replace switches every 2 years regardless of whether they are operating properly or not. 1.
To Push the Machine Testing the Safety Interlock System 1. Park the machine on a level surface. 2. Disengage the blades (PTO). CAUTION 3. Set the parking brake. 4. Stop the engine and wait for all moving parts to stop. If the safety interlock switches are disconnected or damaged, the machine could operate unexpectedly, causing personal injury. 5. Remove the ignition key. 6. Remove the grass collector; refer to Removing the Grass Collector. • Do not tamper with the interlock switches. 7.
2. Place your foot on the traction control pedal and slowly press on the pedal to move forward (Figure 14). CAUTION Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended. 1 Always remove the ignition and KeyChoice keys and set the parking brake when leaving the machine unattended, even if it is just for a few minutes. 2 Emptying the Grass Collector When the grass collector is full, a buzzer sounds, and the grass collector must then be emptied.

Operating Tips • For the best performance, operate the engine at the maximum speed. The mower requires air to thoroughly cut grass clippings, so do not set the height-of-cut too low or completely surround the mower in uncut grass. Always leave one side of the mower free from uncut grass to allow the air to be drawn into the mower. • Cut the grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground.
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 5 hours • Change the engine oil. Before each use or daily • • • • • • Check the safety interlock system. Check the engine oil level. Check the battery electrolyte level. Check the brake. Check the blades. Clean the mower housing. Every 25 hours • Grease and lubricate the machine.
5. Clean the grease fittings with a rag. Scrape any paint off the front of the fittings. 6. Connect a grease gun to each fitting and pump grease into it. 7. Wipe up any excess grease.
Engine Maintenance Replace the air filter if it is damaged or cannot be cleaned thoroughly. Servicing the Air Cleaner Installing the Air Filter Service Interval: Every 25 hours—Service the air filter. (Service it more frequently when operating the machine in dusty or dirty conditions.) 1. Install the air filter into the engine base and push down until the filter snaps in place. 2. Install the air filter cover and knobs (Figure 21). 3. Close the hood. Every 100 hours—Replace the air filter.

Screw the dipstick fully onto the filler tube (Figure 23). 11. Unscrew the dipstick again and look at the metal end.
6. Fill the crankcase with the proper type of new engine oil; refer to Checking the Engine Oil Level. Servicing the Spark Plug Service Interval: Every 25 hours—Check the spark plug. Every 100 hours—Replace the spark plug. Figure 27 Use a Champion RC12YC or equivalent spark plug. Ensure that the air gap between the center and side electrodes is 0.76 mm before installing the spark plug.
Fuel System Maintenance 10. Install the fuel line onto the fuel filter. 11. Slide the hose clamp close to the fuel filter to secure the fuel line (Figure 28). Draining the Fuel Tank Replacing the Fuel Filter Drain the fuel tank when you will not be using the machine for more than 30 days. Service Interval: Every 100 hours/Yearly (whichever comes first) The best time to replace the fuel filter (Figure 28) is when the fuel tank is empty.
Electrical System Maintenance 1. Disengage the blades (PTO). 2. Set the parking brake. 3. Stop the engine and wait for all moving parts to stop. 4. Remove the ignition key. Replacing the Fuses 5. Lift up the seat to see the battery. The electrical system is protected by fuses. They are located beneath the hood, near the fuel tank (Figure 30). If a fuse goes out, check the circuit wiring for a short. 1 6. Lift the rubber cover up off the negative (black) cable. 7.
Important: Do not overfill the battery. Electrolyte (sulfuric acid) can severely corrode and damage the chassis. 3. Using the bolt and wing nut, connect the positive (red) cable to the positive (+) battery post (Figure 31). Slide the rubber cover over the battery post. 4. Using the bolt and wing nut, connect the negative (black) cable to the negative (–) battery post (Figure 31). Slide the rubber cover over the battery post. 4. Replace the filler caps.
Drive System Maintenance 2. Disengage the blades (PTO). 3. Set the parking brake. 4. Stop the engine and wait for all moving parts to stop. 5. Remove the ignition key. Checking the Tire Pressure 6. Pull the drive control out to the Push position (Figure 13). Service Interval: Every 25 hours/Yearly (whichever comes first) 7. If the rear wheels lock and skid when you push the machine forward, you do not need to adjust the brake.
Cleaning the Grass Collector and Tunnel Servicing the Grass Collector 1. Disengage the blades (PTO). Removing the Grass Collector 2. Set the parking brake. 3. Stop the engine and wait for all moving parts to stop. 1. Lock the locking pin on the grass collector (Figure 35). 4. Remove the ignition key. 1 5.

Mower Deck Maintenance Removing the Blades 1. Remove the mower; refer to Removing the Mower. 2. Carefully tip the mower over. 3. Remove the bolts, washers, and blades (Figure 37). Wedge a block of wood between each blade and the mower to lock the blade when you are removing each bolt. Servicing the Blades Service Interval: Before each use or daily Note: Determine the left and right sides of the machine from the normal operating position. Note: The right blade has a left-hand threaded bolt. 4.
1. Measure the distance between the front tip of the left blade and the flat surface (Figure 41). Repeat for the rear tip of the left blade. 3. Set the parking brake. 4. Stop the engine and wait for all moving parts to stop. 5. Remove the ignition key. 6. Disconnect the wire from the spark plug. 7. Move the height-of-cut lever to the lowest position. 8. If the mulch plug is installed, remove it; refer to Removing the Mulch Plug. 9. Remove the belt from the clutch pulley (Figure 40).
Leveling the Mower from Side-to-Side The mower blades must be level from side to side. Check the side-to-side level whenever you install the mower or if you notice that your lawn has an uneven appearance. 1. Carefully rotate the blades side to side (Figure 43).
