Proper maintenance is key to ensuring that the Bobcat 753 runs smoothly and efficiently over the years. Regular checks and timely servicing help prevent common issues, reduce downtime, and extend the machine’s lifespan.
- Engine Maintenance
- Oil Change: Change the engine oil every 250 hours or as recommended in the owner’s manual. This helps to reduce engine wear and maintain optimal performance.
- Air Filter: Inspect and clean the air filter every 100 hours or more frequently in dusty conditions. A clogged air filter reduces engine efficiency and can cause overheating.
- Fuel System: Check the fuel filters and clean the system to avoid clogs that can affect engine performance. Replace the filters as per the manufacturer’s recommendation.
- Oil Change: Change the engine oil every 250 hours or as recommended in the owner’s manual. This helps to reduce engine wear and maintain optimal performance.
- Hydraulic System
- Fluid Levels: Check the hydraulic fluid level regularly, ideally after every 50-100 hours of operation. Low hydraulic fluid can cause poor performance and potentially damage the system.
- Hydraulic Fluid and Filter Replacement: Change the hydraulic fluid and filters every 1,000 hours or as recommended in the manual. Regular replacement ensures that the hydraulic system operates at its best and avoids premature wear.
- Leak Check: Regularly inspect hoses, fittings, and seals for leaks. Hydraulic leaks can cause system pressure loss, leading to reduced lifting capacity.
- Fluid Levels: Check the hydraulic fluid level regularly, ideally after every 50-100 hours of operation. Low hydraulic fluid can cause poor performance and potentially damage the system.
- Tire Maintenance
- Pressure Check: Check tire pressure frequently, especially before starting work. Tires that are under-inflated can wear out prematurely and reduce performance. Refer to the manual for the proper tire pressure.
- Tire Wear: Inspect tires for any signs of excessive wear or punctures. Uneven wear could be a sign of mechanical issues, such as misalignment or overloading.
- Pressure Check: Check tire pressure frequently, especially before starting work. Tires that are under-inflated can wear out prematurely and reduce performance. Refer to the manual for the proper tire pressure.
- Greasing
- Lubrication: Grease all moving parts, such as the lift arms, bucket pivots, and the quick-tach system, every 50-100 hours of operation. Regular lubrication reduces friction, prevents rust, and extends the life of components.
- Lubrication: Grease all moving parts, such as the lift arms, bucket pivots, and the quick-tach system, every 50-100 hours of operation. Regular lubrication reduces friction, prevents rust, and extends the life of components.
