Are Hydraulic Machines more expensive to buy and maintain?
Yes and No. They are more expensive to build. That is why most pallet nailers being pushed on the market really have nothing to do engineering how they are going to drive nails. You need very little background and experience to move a pallet, but you do need the experience when it come to driving a nail and doing it right. A GBN Hydraulic Nailer does not emulate an air gun. It presses the nail in place and puts a spin on it so that it screws into place so that the wood is not damaged. Hydraulics are far more reliable and positive that air. Air compresses, it susceptible to moisture and freezing and does not lubricate itself. The landing gear on an airplane would have a real problem if the plane builder went on the cheap and tried to raise and lower the gear with air. Can you imagine? So really which do you think is better?
