To start the McCulloch ProMac PM655 HW Lawn Mower, ensure that the fuel tank is filled and the oil level is adequate. Engage the choke, pull the starter cord firmly, and adjust the choke as the engine warms up.
If the lawn mower does not start, check the fuel level, ensure the spark plug is clean and properly connected, and verify that the air filter is not clogged. Also, make sure the safety features are engaged.
Sharpen the blades at least once per mowing season or more frequently if you notice uneven cutting or the grass appears torn rather than cleanly cut.
Use SAE 30 oil for temperatures above 40°F (4°C) and SAE 10W-30 for varying temperature ranges. Always check the owner's manual for specific oil recommendations.
If the lawn mower smokes, check the oil level to ensure it is not overfilled. Inspect the air filter for clogs, and verify that the oil is not leaking into the exhaust.
Perform regular maintenance every 25 hours of operation or annually. This includes changing the oil, cleaning or replacing the air filter, inspecting the spark plug, and sharpening the blades.
To clean the air filter, remove the cover, take out the filter, and wash it with warm soapy water. Allow it to dry completely before reinstalling. Replace if it is excessively dirty or damaged.
Excessive vibration can be caused by unbalanced blades or loose parts. Check and tighten any loose bolts and nuts, and inspect the blades for damage or imbalance.
To improve cutting performance, ensure the blades are sharp, the deck is clean from grass build-up, and that you mow at the recommended height for your grass type.
Always wear protective gear, such as safety glasses and gloves. Keep bystanders at a safe distance, and never operate the mower on wet or slippery ground. Follow all safety instructions in the manual.
