EC-250 Router 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 lubricator is highly recommended to increase tool life as well as keeping the tool in sustained operation. If in-line lubricator is not used, the tool should be lubricated several times daily by disconnecting the air hose and injecting a few drops of a high grade No. 10W machine oil in the air inlet.

Disassembly:

Remove Nose Assembly: Clamp the throttle body in a vise with the tool in a vertical position and remove Nose Assembly using a suitable spanner wrench.

Remove Motor Housing: Unscrew (right hand threads) the bearing retainer. The motor housing may now be unscrewed from the throttle body with the aid of a strap wrench, if necessary.

Change Rotor Blades: If the reason for disassembling the tool is to change the rotor blades, use a 1/4 or 5/8 inch brass or aluminum rod and remove the rear bearing and rear bearing plate from the rotor. By sliding cylinder off the rotor, the rotor blades can now be replaced.

Remove Collet Spindle: To remove the collet spindle or either of the bearings, insert a 3/16 inch allen wrench into the opening of the collet spindle and unscrew the collet spindle from the rotor. Now the bearings can be removed from the rotor.
