EC–7C-2 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:

Clamp the throttle body in a soft-jawed vise with the tool in a vertical position. After removing the nose and collet nut, and using a suitable spanner wrench, unscrew (left hand threads) the bearing retainer ring. The motor housing may now be unscrewed from the throttle body with the aid of a strap wrench.

Bump the rear of the motor housing lightly on the bench to remove the motor unit from the rotor. The rotor shaft and related components may now be pressed out the front of the housing. The throttle valve may be removed by driving the throttle lever pin out of the throttle lever. Unscrew the hose adapter for inspection and cleaning of the air screen.

Product Safety Warnings

For your safety, make sure you apply standard shop practices at all times when using this tool. Your failure to apply these practices may result in serious bodily injury.

Protect your eyes, ears, and other parts of your body by using safety equipment - respirator, safety goggles, ear mufflers and other necessary safety devices - at all times when operating this tool or when you are in the area where this tool is being operated.

For maximum stability and safety, only operate these tools with both hands on the tool. Follow the cutting tool manufacturer’s mounting and operating instructions and avoid any direct contact with the sharp cutting edges of the tool.

Modification or improper use of this tool, including, but not limited to, removing guards, mufflers, or other safety devices, voids all responsibilities of the manufacturer.

Excessive air pressure, over and above 90 PSI, will increase the RPM, the sound level, and can be a damaging factor to both the operator and the tool.

Stay alert! Watch what you are doing! Do not operates this tool when under the influence of medication, alcohol, or drugs!

Disconnect the air supply before changing the cutter and whenever making adjustments or repairs.

Do not remove warning tags until both sides have been read and understood by the person(s) responsible for safety in your plant.
