OPERATION & USE
AIR SUPPLY
This nailer operates at a maximum of 120PSI and should be controlled via a combined
regulator, oil and water separator such as the Draper 4222/3 unit which with proper
maintenance will ensure a constant supply of dry air and lubricating oil at all times.
See illustration below. Always check machine operating pressure before use.
Water in the compressor tank will cause serious corrosion to your air tools and should
be drained daily to avoid excessive water in your air supply. Dirty wet air rapidly
shorten the life of your air tool.
If you are using an air tool on a hose over 25ft. long, it is advisable to increase the bore
of the hose to the next larger size available, ie.
1 ⁄
4
" increases to 3 ⁄
8
". This will ensure
adequate pressure and volume of air to power the machine.
