How to choose lubricating oil

Anyang ST power hammers will recommend 5W-40 or 10W-40 lubricating oil depending on different room temperatures. The power hammer working frequency and piston gap is much bigger than engineers, so using the engine oil will be good enough for the hammer.

The hammer working temperature will be around 70 degrees, the thin oil is easy to be volatilized as white smoking, if so, please try to change the oil to a thicker oil.

Oiler Working Principle

The oiler of the power hammer consists of an oil reservoir, a flowing control needle valve, and one-way check valve. The system is simple but reliable as a lubricating system.

The compressor cylinder will create a vaccuum that will suck oil from the reservoir when the compressor piston is on the downstroke. When the compressor piston is on its upstroke, the one-way check valve closes to keep oil from flowing back into the reservoir.

The right oil can prolong the hammer working life, and reduce the resistance to make the hammer controlling very smooth. Normally, Anyang ST power hammers require minimal maintainance with the correct lubricating and greasing.

Mineral oil, Semi-synthetic OR Fully synthetic?

The lubricating oil should be mineral, semi-synthetic or fully synthetic. There are many of users to ask this questions. The oil will not recycle in the hammers system, most of the oil will be volatilized be removed out the hammer following air flow. What is left will flow to the bottom of the hammer rear cylinder, the copper valve is used to drain the waste oil.

So, mineral oil will be good for the hammer don’t need to pay more to buy synthetic oil. if you want to learn more, please contact at Blacksmithsource@gmail.com
