Preventative Maintenance Procedures and Safety Guidelines
To ensure the safe operation and regulatory compliance of equipment, a comprehensive preventative maintenance program is essential. This program should include regular inspections, servicing, and adherence to safety guidelines. The following outlines recommended procedures and guidelines based on industry best practices and manufacturer recommendations.
General Safety Practices
Before servicing any equipment, it is crucial to follow general safety practices to prevent accidents and injuries.
- Read the entire maintenance procedure section to understand the tasks involved.
- Familiarize yourself with all safety precautions outlined in the equipment's safety manual.
- Pay close attention to all safety alert symbols, which indicate potential hazards.
- Ensure you fully understand the procedures detailed in the maintenance section.
- Wear appropriate protective equipment, such as gloves, safety glasses, and hearing protection.
- Remove rings and jewelry to prevent them from getting caught in machinery.
- Move the machine to a safe, level work area to ensure stability.
- Lower the boom or any raised equipment and support it properly to prevent accidental lowering.
- Shut down the machine completely before starting any maintenance work.
- Remove the key from the ignition to prevent unauthorized operation.
- Exercise caution when handling fuels and lubricants to avoid spills.
- Never fuel the tank while the engine is running or hot, as this could cause a fire or explosion.
- Refrain from smoking while refueling or working with fuel to prevent fire hazards.
- Clean up any spilled fuel or lubricants immediately to prevent environmental contamination and slip hazards.
Daily (Pre-Use) Inspections and Maintenance
Daily inspections are critical for identifying potential issues before they escalate into major problems. These inspections should be performed before each work shift to ensure the equipment is in safe operating condition.
- Ensure all operation and safety decals are in place and easy to read. Replace any missing or damaged decals to maintain clear safety instructions.
- Check the hydraulic tank fluid level and add oil as required to maintain proper system function.
- Check the water level in the batteries and add water as needed to ensure optimal battery performance.
- Inspect for loose or worn hardware, wire connections, etc. Repair or replace any damaged or missing components.
- Inspect the controls for proper operation, ensuring they function smoothly and respond correctly.
- Check for and correct any hydraulic leaks to prevent fluid loss and potential system failures.
- Check for and correct any cracked welds or other structural damage that could compromise the equipment's integrity.
- Check for good overall performance, noting any unusual noises, vibrations, or performance issues.
- Check engine oil level and add oil if required, following the engine manufacturer's recommendations.

- Check the condition of the tires, ensuring they are free of serious cuts or defects.
- Check for proper brake operation to ensure reliable stopping power.
- Record the hour meter reading to track usage and schedule maintenance intervals.
- Clean the unit by removing all dirt, oil, and grease. The machine may be washed with soap and water, but avoid electrical panels and charging units.
- Check for signs of wear on electrical cables and hoses, repairing or replacing them if necessary.
- Check and lubricate components as necessary, following the manufacturer's recommendations.
- Check battery condition to ensure it is holding a charge properly.
- Check that operation and safety decals are in place and readable.
- Check overall performance.
Monthly (or First 50 Hours) Maintenance
- Change the hydraulic oil return filter (first 150 hours of operation).
- Check engine oil and filter. Change per engine manufacturer's recommendations.
