Starting and Shutting Down Liebherr Machines - Operator's Guide

Introduction

Proper operation of construction machinery is crucial for ensuring safety at the construction site and extending equipment lifespan. In this guide, we present detailed instructions on starting and shutting down Liebherr machines, which are commonly used in demolition and earthworks.

Pre-start Inspection

Before starting the machine, the operator should perform the following checks:

1. Visual inspection - walk around the machine, checking:

   • Condition of tires or tracks
   • Potential fluid leaks
   • Condition of working attachments
   • Presence of mechanical damage

2. Fluid level checks:

   • Check engine oil level
   • Check coolant level
   • Check fuel level
   • Check hydraulic fluid level

3. Cabin check:

   • Ensure control levers are in neutral position
   • Check window cleanliness for good visibility
   • Adjust the operator's seat to your weight and height

Starting Procedure for Liebherr Machines

Step 1: Entering the Cabin

• Always use three points of contact when entering the cabin
• Close the cabin door to ensure optimal protection

Step 2: Preparation for Start-up

• Fasten your seatbelt
• Make sure all control levers are in neutral position
• Check that the parking brake is engaged

Step 3: Engine Start

• Insert the key into the ignition
• Turn the key to the "ON" position - dashboard indicators will light up
• Wait until the glow plug indicator turns off (in machines with diesel engines)
• Turn the key to the "START" position and hold until the engine starts
• After the engine starts, release the key - it will automatically return to the "ON" position

Step 4: Engine Warm-up

• Allow the engine to idle for 3-5 minutes
• In low temperatures, the warm-up time should be longer
• Monitor the indicators on the dashboard, making sure that:
  • Oil pressure is correct
  • Engine temperature gradually increases
  • No warning lights are illuminated

Step 5: Preparation for Work

• Unlock the control console (depending on the model)
• Release the parking brake
• Slowly lift the working attachment from the ground
• Perform several hydraulic movements to warm up the hydraulic oil

Shutdown Procedure for Liebherr Machines

Step 1: Safe Stopping

• Find level, stable ground
• Stop the machine and set the travel lever to neutral position
• Engage the parking brake

Step 2: Positioning the Attachments

• Lower the working attachment (bucket, blade) to the ground
• Set the arm and boom in the resting position, according to manufacturer recommendations

Step 3: Engine Cooling

• Allow the engine to idle for 2-3 minutes
• Cooling the engine is important for extending its lifespan

Step 4: Engine Shutdown

• Turn the key to the "OFF" position
• Remove the key from the ignition
• Secure the control console (if applicable)

Step 5: Securing the Machine

• Close all windows
• Check that the cabin is secured
• Lock the cabin door
• Ensure the machine is properly marked if it remains at the construction site

Additional Tips

Safety

• Never start the machine if you are not authorized to do so
• Make sure there are no bystanders near the machine
• Always wear appropriate protective clothing and personal protective equipment

Work Efficiency

• Regular fluid checks and daily inspections extend machine lifespan
• Proper machine warm-up before work reduces component wear
• Correct machine shutdown prevents damage to the engine and hydraulic system

Summary

Proper starting and shutting down of Liebherr machines is a key element of safe and efficient work at the construction site. Following the described procedures will help extend equipment lifespan, minimize the risk of failure, and ensure safety for operators and other workers.
