Disconnect Power: Unplug your Shop Vac vacuum cleaner from the electrical outlet.

Disconnect Old Switch: Carefully disconnect the wires from the old switch. Note the position of each wire.
Remove Old Switch: Unclip or unscrew the old switch from its mounting slot.
Install New Switch: Insert the new Earthtec power switch into the mounting slot. Ensure it clips securely into place.
Connect Wiring: Refer to the photograph taken in step 3 and connect the wires to the new switch's terminals. Ensure all connections are secure. Note: While the product specifications mention "2 Pin" for the connector type, the feature bullets indicate "4 Pin" for the original Shop Vac switch. This replacement switch is designed to work with the existing wiring by connecting the appropriate wires to its terminals. If your original switch has 4 wires, consult your vacuum's specific wiring diagram or a qualified technician for correct connection to this 2-pin replacement.
Reassemble: Close the motor housing and secure it with the screws.
Test: Plug the vacuum cleaner back into the electrical outlet and test the new power switch.

6. Operation

The Earthtec Shop Vac Power Switch Replacement operates as a standard ON-OFF rocker switch.

To turn the vacuum cleaner ON, press the side of the rocker switch marked 'I' or the side that illuminates (if applicable).
To turn the vacuum cleaner OFF, press the side of the rocker switch marked 'O' or the opposite side of the 'ON' position.

7. Maintenance

The power switch itself requires minimal maintenance. However, regular inspection of the vacuum cleaner's electrical components can prolong its lifespan.

Periodically inspect the switch for any signs of physical damage or wear.
Ensure the area around the switch is kept clean and free of dust or debris.
If the switch feels loose or unresponsive, discontinue use and inspect for proper installation or damage.

If you encounter issues after installing the replacement switch, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
