Mechanical Water Timer - Claber - 8421

No, the Claber 8421 is a mechanical timer and does not require any batteries or external power source.

You can set the watering duration for a maximum of two hours (120 minutes).

It is designed to connect to standard 1/2-inch or 3/4-inch male threaded garden taps.

By allowing you to precisely set the watering duration, it prevents overwatering and ensures water is only used for the time needed, especially useful after rainfall or when manual watering is forgotten.

No, this is a purely mechanical timer. You must manually set the duration each time you want to water.

It is recommended to disconnect and store the timer indoors during freezing weather to prevent damage from ice expansion.

The timer automatically stops watering once the set duration has elapsed. You do not need to manually reset it unless you wish to change the duration for the next watering cycle.

Ensure the dial is properly set to a specific duration and not left at the 'off' position or fully turned past its range. Check that the internal mechanism is not obstructed.

Ensure the timer is screwed on tightly to the tap. Check the rubber washer inside the connection for wear or damage and replace if necessary.

Check that the water supply to the tap is fully open. Ensure there are no kinks in the hose connected to the timer. Water pressure might be too low for consistent operation, especially for longer durations.

Gently try to rotate the dial back and forth. If still stiff, a small amount of silicone lubricant might help, but avoid excessive use. Ensure no debris is lodged around the dial.
