32. What kind of maintenance is involved?

33. Why don’t I need to clean the tool regularly like other gas nailers?

The Grex cordless is designed to be as low maintenance as possible. The piston seals are made of PTFE, a self lubricating material. Additionally the piston cylinder is also coated with PTFE. This results in very minimal wear of the piston seals and lubrication is not necessary. Even the valves of the fueling system are made of PTFE. Simply put, lubrication is not necessary because critical parts are manufactured with premium materials.

Other gas powered nailers use a steel piston seal which requires oil for lubrication. This oil is already pre-mixed with the fuel in the fuel cell so that oil is dispensed into the combustion chamber each time fuel is injected. Ironically, this is the root to a lot of their maintenance issues. Imagine combusting the gas in the presence of oil. This results in tar buildup inside the combustion chamber and piston cylinder. Over time, this buildup prevents the tool from functioning properly and it must be fully disassembled to be cleaned, costing the user both time and money.
