EC-600 Saw Service & Maintenance Instructions

Operation:

The tool is designed to operate on 90 PSI air pressure using a 3/8 inch hose up to 8 feet in length. If additional hose is required, a 1/2 inch or larger hose should be connected to the 3/8 inch hose.

Lubrication:

An automatic in-line filter-lubrication is highly recommended to increase tool life as well as keeping the tool in sustained operation. If in-line lubrication is not used, the tool should be lubricated several times daily by disconnecting the air hose and pouring a few drops of a good grade of No. 10W machine oil into the air inlet.

The angle head should be greased every forty (40) hours of operation with a good grade of grease, using a low pressure grease gun.

    3/16 inch hex allen wrench into the opening in the
    bearing cap EC 9974 to reach the internal hex in the
    end of the cutter shaft EC 9977.
