To adjust the cutting height, locate the height adjustment levers on each cutting unit. Move the levers to the desired position as indicated on the height scale. Ensure all units are set to the same height for an even cut.
If the mower won't start, check the battery connections and ensure they are clean and tight. Verify that the fuel tank has sufficient fuel and that the fuel shut-off valve is open. Also, inspect the spark plug for fouling and replace if necessary.
Blades should be sharpened after approximately every 10 hours of use or whenever you notice a decrease in cutting performance. Regular sharpening ensures a clean cut and reduces strain on the mower.
The recommended tire pressure for the PrecisionCut 7500A Mower is typically 22 psi for the front tires and 20 psi for the rear tires. Always refer to the operator's manual for specific details.
To change the oil, start by running the engine to warm it up. Turn off the engine and remove the drain plug to let the old oil drain completely. Replace the drain plug, remove the oil filter, and install a new one. Finally, refill with the recommended engine oil.
Uncut strips can be caused by dull blades, incorrect cutting height, or improper reel-to-bedknife adjustment. Check and sharpen the blades, ensure even cutting height, and adjust the reel-to-bedknife clearance as needed.
Routine maintenance includes checking and replacing the air filter, changing the engine oil and filter, inspecting the spark plug, and checking the fuel system for leaks. Refer to the service manual for a detailed maintenance schedule.
Inspect the hydraulic fluid level and top up if necessary. Check for leaks in hoses and connections. If the problem persists, consult the hydraulic system diagram in the service manual to diagnose further.
Always wear protective gear, ensure the area is clear of bystanders, and check that all safety guards are in place. Familiarize yourself with the machine's controls and emergency shut-off procedures before operating.
Clean the mower thoroughly, change the oil, and add a fuel stabilizer to the gas tank. Store the mower in a dry, sheltered location, and disconnect the battery to prevent drainage.
