Product Overview
The STANLEY 2-Outlet Indoor Mechanical Timer features a rotating dial with 24-hour markings and multiple pins for setting ON/OFF times. It includes two polarized outlets for connecting appliances.

Figure 1: Front view of the Stanley 2-Outlet Indoor Mechanical Timer. The central dial displays time markings (AM/PM) and has small, push-down pins around its circumference. Two polarized outlets are visible on the left side of the unit.
Key Components:
- 24-Hour Dial: The large rotating dial marked with hours (1-12 AM and 1-12 PM).
- Timing Pins: Small, push-down segments around the dial. Each segment represents a 15-minute interval. Pushing a pin DOWN turns the connected device ON during that interval. Pushing a pin UP turns the connected device OFF.
- Current Time Arrow: A stationary arrow or marker on the timer's body that indicates the current time on the rotating dial.
- Polarized Outlets: Two outlets located on the side of the timer for connecting appliances.
- Manual ON Override Switch: A switch (if present, based on product description "Manual ON override switch") to manually turn the connected devices ON or OFF, overriding the timer settings. (Note: The provided image does not clearly show this switch, but the product description mentions it.)
Setup Instructions
- Set Current Time: Rotate the 24-hour dial clockwise until the current time aligns with the stationary arrow on the timer's body. Ensure to distinguish between AM and PM hours.
- Program ON/OFF Times:
- Locate the small pins around the outer edge of the dial. Each pin represents a 15-minute interval.
- Push the pins DOWN for the periods you want the connected appliance to be ON.
- Leave the pins UP for the periods you want the connected appliance to be OFF.
- Connect Appliance: Plug your appliance(s) into the polarized outlets on the side of the timer.
- Plug Timer into Wall: Insert the timer into a standard indoor wall outlet.
The timer will now begin its programmed cycle, repeating daily.
Operating Instructions
Manual Override:
If your timer includes a manual ON override switch, you can use it to temporarily turn the connected devices ON or OFF, regardless of the programmed settings. Once the switch is returned to the "Timer" position, the unit will resume its programmed schedule.
Adjusting Programmed Times:
To change the ON/OFF schedule, simply pull up or push down the desired pins on the 24-hour dial. No need to unplug the timer from the wall, but ensure the appliance is off or unplugged if you are making significant adjustments to avoid accidental activation.
