How to fix your TaskForce air compressor when it won't build tank pressure
Shut the drain valve at the bottom of the tank if it's open. Check for air tank leaks and replace the tank if it's leaking. Tighten loose air tube fittings to prevent air leaks. The safety valve pops open to relieve excessive air pressure if the pressure switch fails to shut off the air compressor at the cut-out pressure setting. Replace the safety valve if it leaks air constantly. Worn pump seals prevent the pump from compressing air. If the pump won't compress air, rebuild the pump. The valve plate regulates airflow into and out of the pump cylinder to compress air, so replace the valve plate if damaged.
Fixing air leaks on your TaskForce air compressor
Tighten air tube fittings where air escapes and replace any damaged air tubes. The check valve prevents tank air from back flowing to the pump and unloader. If air leaks out the unloader when the pump stops, replace the check valve because the check valve leaks air back towards the unloader. The safety valve pops open to relieve excessive air pressure if the pressure switch fails to shut off the air compressor at the cut-out pressure setting. Replace the safety valve if it leaks air constantly. Replace the air compressor tank if it leaks air. Rebuild the air compressor pump if it leaks air through the pump head when the pump runs because a broken valve plate seal is allowing air to escape through the pump head.
