Bobcat excavators, marketed as versatile compact excavators, are highly valued in the construction and landscaping industry. Their compact size makes them ideal for working in confined spaces where larger machines cannot operate effectively. Whether you are using a brand-new or a used excavator, understanding the machine's design and capabilities is imperative.
Bobcat machines consist of a boom, arm, bucket, and a rotating platform mounted on tracks or wheels. Familiarity with these components helps the operator control digging depth, reach, and load management.
Many businesses and contractors prefer used excavators due to their affordability and availability. When purchasing a used Bobcat excavator, ensure it is inspected thoroughly for wear, engine condition, and hydraulic functionality to avoid downtime. Buying a quality used excavator allows businesses to manage costs while still accessing reliable equipment for various tasks.
Before operating the Bobcat excavator, familiarize yourself with its control panel and levers. While different models may have slight variations, most include:
- Joystick Controls: These control the movement of the boom, arm, and bucket. Typically, one joystick handles the boom and bucket, while the other controls the arm and swing.
- Travel Levers or Pedals: Used to maneuver the tracks or wheels forward, backward, or for turning.
- Throttle Control: Regulates the engine speed to optimize power output and fuel consumption.
- Attachment Control: For auxiliary tools connected to the excavator, allowing for attachment-specific commands.
- Swing Control: Allows the upper structure of the excavator to rotate horizontally 360 degrees.
Understanding how these controls work together is essential to operate the machine with precision and efficiency.
Watching instructional videos from the manufacturer or trusted sources helps visualize these operations. Many training videos for Bobcat excavators are available online, showing step-by-step handling which is essential for new users, especially when handling more complex tasks or used excavators that may have less responsive controls.
Whether new or used, inspecting a Bobcat excavator before each use minimizes the risk of accidents and ensures optimal performance. The inspection checklist includes:
- Check Fluid Levels: Engine oil, hydraulic oil, coolant, and fuel should be at recommended levels. Low hydraulic fluid can lead to sluggish controls or complete hydraulic failure.
- Visual Inspection: Look for leaks, cracks, dents, or damage in hoses, cylinders, tracks, and undercarriage parts. Check for unusual wear that could indicate mechanical problems.
- Check Attachments: Ensure the bucket or other tools are securely fastened and show no cracks or excessive wear.
- Test Control Functions: Verify that all joysticks, pedals, switches, and buttons respond correctly and smoothly. Sticky or unresponsive controls can be hazardous.
- Safety Devices: Confirm that seat belts, horns, backup alarms, and emergency shutoffs are functioning.
Performing these checks can be documented with photos or videos for maintenance records, providing a good habit that especially applies to used excavators, where previous wear and tear should be closely monitored. Regular inspection is critical to prolonging the lifespan of your equipment.
Starting a Bobcat excavator correctly improves both safety and equipment longevity. Follow these steps:
1. Enter the Cabin: Use handrails and steps for secure and stable entry to the operator seat.
2. Fasten Seatbelt: Always buckle up before starting the machine to keep safe in case of sudden movements.
3. Insert Key and Turn On: Turn the ignition key and allow the system to complete a self-diagnostic test. Look for any warning indicators.
4. Warm Up the Engine: Let the engine idle for a few minutes before starting any heavy digging or movement to allow hydraulic fluid circulation and engine components to reach optimal temperature.
5. Check Gauges and Indicators: Ensure oil pressure, temperature gauges, and hydraulic pressures stay within normal ranges during warm-up.
6. Test Movement and Swing: Gradually manipulate the joysticks to test lifting, lowering, swinging, and digging functions, ensuring full control responsiveness.
A video demonstration can significantly enhance comprehension of these steps, showing operators how to perform each action correctly and confidently.
Operating a Bobcat excavator efficiently involves mastering several techniques to work effectively across various terrains and tasks.
- Use travel levers or pedals to move forward, reverse, or turn. Always move at controlled speeds to avoid tipping, especially on slopes.
- Lower the bucket close to or on the ground when driving, which helps stabilize the machine.
- When working in confined spaces, practice precise slow movements to avoid damaging surrounding structures or equipment.
- If on uneven ground, move diagonally uphill and avoid making sharp turns on slopes to maintain balance.
- Use the boom and arm to extend the digging reach; operate the bucket with smooth motions to reduce wear on hydraulic components.
- When digging, consider the soil condition; wet or rocky soil may require different bucket angles and force application.
- Avoid overloading the bucket as this can strain hydraulics and reduce machine stability.
- Swing the boom smoothly to deposit material into trucks or piles to prevent backlash and mechanical shocks.
Bobcat excavators often support various attachments such as augers for drilling, trenchers for ditching, hydraulic breakers for demolition, and grapples for material handling. The attachments expand the machine's versatility:
- Always follow manufacturer guidelines to switch and operate attachments safely.
- Check hydraulic pressure requirements for each attachment.
- Conduct test runs with new attachments to familiarize yourself with control differences.
Maintaining a used excavator extends its life and ensures reliability. Unlike brand-new machines, used excavators may have hidden wear components that require additional care.
