Depending on how often you use the machine, once every few weeks or once a month, you should flush out the radiator fins. If they are plugged up with dirt and debris it’ll inhibit the airflow that cools the engine.
All you need to do is use either a garden hose or a pressure washer to wash the fins clean, from the outside in.
Some of our older machines come with APT compressors, on which the alternator is right behind the radiator. If you plan to pressure wash the radiator fins on an APT compressor, simply put a piece of cardboard in front of the alternator to protect it. You can always use compressed air instead, and not worry about protecting the alternator.
After cleaning the radiator, now is a great time to check your coolant levels as well as add any coolant additive, such as Purple Ice, to improve your radiator's overall performance.
All compressors have air intake filters, which are to be changed at regular service intervals. If you are not yet due for a change but notice your machine running poorly (i.e. losing pressure), you should check the air filters.
All of our compressor models have 4 air intake filters - 2 for the engine and 2 for the compressor. Find and remove both the engine air filters and the compressor air filters, and simply shake any dust or debris out. You can also use compressed air to clean these, but be gentle. These air filters are just made of paper, and high pressure air could damage them. Never clean the air filter with water.
This will help the compressor maintain a good running pressure until it's time to change the filter.
Go through and check your connecting hoses for leaks or cracks. After that, check all the mounting bolts as well as fittings to make sure everything is tight and hasn’t vibrated loose.
Refer to the appropriate user manual for the maintenance schedule of your machine — when to replace the oil, fuel, and air filters etc. Find your user manual here.
