Summertime means hotter temperatures, humidity, increased sun exposure and dry conditions. And with those higher temperatures comes an increased risk of equipment overheating, engine problems and unnecessary wear. All of that, combined with a heavy summer workload, can add up to maintenance challenges. But with some basic routine care, your equipment can be in top working condition all summer long.
Here are some tips on maintaining your equipment in good working order when the heat is on.
Make daily checks on hydraulic fluid and coolant to ensure they are topped off and effective for higher temperatures. Also take a moment before work starts to check the AC and the tire pressure to avoid premature tire wear.
Modern cooling radiators are made to run totally full in order to eliminate oxygen from entering the cooling system. Check the radiator cap for proper check valve operation and proper relief pressure.
Newer OAT (organic acid technology) is used in more recent machines, while a silica-based coolant is used in older machines. Mix the two together and gelling will take place, which will drastically reduce cooling efficiency. If the machine has OAT, there will be a tag on or near the coolant fill location that clearly identifies it.
A 50-50 concentration is best for machine operation, as too much water can lead to corrosion, a lower boiling point and cavitation.
Keep radiators and cooling packages clear of any debris.You can also change the settings for more frequent automatic reversing to assist in removing the debris. Check all inlets and outlets of the engine hoods frequently for debris build-up to maximize airflow through the coolers. If these areas are left dirty, substances like mud will bake to a solid form and become very difficult to remove. Clean these components using compressed air on a daily basis.
Avoid overworking the equipment during the summer. Using it beyond its set capabilities could lead to expensive breakdowns and overheating. Also make sure to let your machine idle before shutting it down to avoid damage to the machine’s turbos.
If everything detailed above looks good, but the machine’s temperature seems a bit high, have your service department check the thermostat opening temperature.
Many machines today come standard with telematics, which makes monitoring the engine temperature a breeze. If there is the odd spike in temperature, that serves as a red flag for potential faults or defects elsewhere in the machine – ultimately helping catch a larger failure before it happens.
When not in use, equipment should be stored in a dry, sheltered place out of the hot sun and scorching heat. Unwanted moisture promotes rust, which could affect other equipment systems.
With regular preventive maintenance and close monitoring of equipment, you can avoid breakdowns and expensive repairs while ensuring operator comfort.
