3. Check and replenish fluids
The transition to warmer weather may require a change in fluid type.
- Fluid viscosity: Winter-grade fluids are designed for cold temperatures. As the weather warms, you may need to switch to a fluid with a higher viscosity (e.g., ISO VG 46 or 68) to ensure optimal performance and prevent breakdown under heat. Always flush the system completely when switching fluid types to avoid contamination.
- Moisture control: Condensation can introduce water into the system, leading to corrosion and fluid degradation. Check reservoir tank bottoms for water and drain if necessary. Ensure desiccant breathers are clean and functional.
4. Test system pressure and performance
Verifying that your system operates at the correct pressures is crucial for both performance and safety.
- Pressure testing: Conduct a pressure test to ensure hoses and components can withstand normal operational pressures.
- Gauge accuracy: Verify that all system pressure gauges are calibrated and functioning correctly. Inaccurate gauges can lead to improper diagnoses and adjustments.
- Tighten connections: Re-torque all hose fittings and connections to the manufacturer’s specifications to prevent leaks and ensure secure operation.
5. Lubricate and protect moving parts
Proper lubrication is essential for reducing friction, preventing wear, and protecting components from corrosion.
- Key lubrication points: Focus on bearings, pivot points, and chains.
- Follow guidelines: Adhere to the manufacturer’s recommended lubrication schedule based on hours of use.
6. Maintain accurate records
Diligent record-keeping is a cornerstone of an effective maintenance program. It moves your team from guessing to knowing.
- What to track: Log the date of each service, parts replaced, fluids added, and the results of all inspections.
- The benefit: A detailed maintenance history is invaluable for troubleshooting future issues, scheduling preventive replacements, and providing essential documentation for warranty claims. It helps identify recurring problems and informs smarter repair decisions over time.
Adopt a proactive maintenance mindset
Spring maintenance should be viewed as an investment, not an expense. The cost of proactive maintenance — typically a few hundred dollars per machine for fluids, filters, and labour — pales in comparison to the cost of in-season failure. A single hydraulic pump replacement can cost upwards of $5,000, not including the thousands lost in project delays and downtime.
Navigating the complexities of hydraulic maintenance requires expertise. Whether you need guidance on selecting the right fluids, sourcing high-quality replacement parts, or designing custom solutions for unique challenges, having a trusted partner is essential.
