Overview of the Link-Belt LS-108BS
The Link-Belt LS-108BS is a compact excavator designed for versatile applications such as landscaping, utility work, and small construction projects. Understanding its basic instruments and controls is essential for operators to maximize safety, efficiency, and machine performance.
This article details the key control features, instrument panel components, and operational tips for the LS-108BS.
Operator Control Layout

• Joystick Controls:
  • Two main joysticks control boom, arm, bucket, and swing functions.
    
  • Left joystick typically manages boom lift/lower and swing left/right.
    
  • Right joystick controls arm in/out and bucket curl/dump.
    
• Travel Levers:
  • Independent levers for left and right track drive.
    
  • Allow forward, reverse, and turning maneuvers.
    
• Pedals and Foot Controls:
  • Auxiliary hydraulic controls (for attachments) are often foot-operated.
    
  • Some models include a pedal for travel or swing function to aid precision.
    
• Throttle Control:
  • Manual or foot throttle adjusts engine RPM for power and fuel efficiency.
    
• Safety and Lockout Controls:
  • Travel and work mode lock levers to prevent unintended movement.
    
  • Emergency stop button for immediate engine shutdown.
    

Instrument Panel and Monitoring

• Engine RPM Gauge: Displays engine speed in revolutions per minute, helping optimize power usage.
  
• Fuel Gauge: Indicates fuel level to prevent unexpected shutdowns.
  
• Coolant Temperature Gauge: Monitors engine temperature to avoid overheating.
  
• Warning Lights and Indicators:
  • Battery charge, oil pressure, hydraulic temperature, and filter status alerts.
    
  • Audible alarms activate in case of critical system warnings.
    
• Hour Meter: Tracks machine operation time for maintenance scheduling.
  
• Hydraulic Pressure Gauge (if equipped): Monitors system pressure for troubleshooting and performance.
  

Operational Tips for Safe and Efficient Use

• Always perform pre-operation checks including fluid levels, leaks, and control function tests.
  
• Use lockout controls when servicing or during transport.
  
• Adjust throttle and control inputs smoothly to extend component life.
  
• Monitor gauges regularly during operation to catch early signs of issues.
  
• Familiarize with emergency stop procedures to ensure quick response if needed.
  

Case Story: Operator Training Enhances Productivity
A small landscaping company invested in operator training focused on the LS-108BS controls. Operators quickly mastered joystick and pedal coordination, leading to faster cycle times and reduced fuel consumption. The company also noticed fewer minor incidents due to proper use of safety lockouts and emergency stops.
Maintenance of Controls and Instruments

• Keep joystick and pedals clean and free from debris to ensure smooth movement.
  
• Periodically inspect electrical connections behind the instrument panel for corrosion or looseness.
  
• Replace worn or cracked control knobs and switches promptly.
  
• Update software or calibrate electronic controls according to manufacturer recommendations.
  

Summary: Mastery of Link-Belt LS-108BS Basic Controls Enables Safe and Effective Operation
Understanding the fundamental instruments and controls of the Link-Belt LS-108BS excavator empowers operators to handle the machine safely and efficiently. Familiarity with the joystick layout, travel controls, instrument panel, and safety features supports optimal machine performance and longevity.
Ongoing training and regular maintenance ensure the excavator remains a reliable asset in diverse job site conditions.
