|What does the adjustment knob at the base of the handle of an Alltrade Model 1806-A-141 1/2" air wrench do?
I do not have a manual for my Alltrade Model 1806-A-141 1/2" air wrench and the product support section of your site keeps giving me an error. Can you tell me what the adjustment knob at the base of the handle does?
Plus, how many drops of oil should I use daily?
You've got an old unit but a good one. The knob at the bottom of the handle is to regulate the air input to the unit. Since this model was made by several factories, they generally used a number 1 thru 4 for air pressure regulation. On some, number 1 is the high pressure and on others, 4 is the high pressure but you can tell which is high or low by the sound of the running unit and also by the speed. Use 5 to 6 drops at the beginning and if you are finished using for a long period of time, another 3 to 4 drops to place it into storage. Understand that the internal parts are made of cast iron and they rust fast and can cause the unit to be inoperative when being placed into operation at a later date. Oil is used as a vehicle to lubricate and also as a vehicle to remove any condensation which was developed as a result of hot compressed air entering a cold impact wrench. With good maintenance of your tool, it should last a lifetime.
Thanks for asking,
