Here are two links that will be handy to keep on file:

http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

T104 is 240Volt timer.
When you open the door, there should be piece of translucent plastic covering the wiring.
As long as plastic cover is in place, it is safe to touch visible timer parts.
If you have a child who might stick something into the timer, then lock timer door.
As a general rule with electrical devices, do not stand on bare ground or wet surface or lean into or touch anything metal while working on timer. Put down dry boards. Same with your circuit breaker panel.

The T104 yellow dial rotates just like a clock.
The dial has ON and OFF trippers attached to outer edge of dial.
As these trippers rotate around they move on-off lever that turns the pool pump or Load on and off.
ON tripper moves lever one direction, and OFF tripper moves same lever other direction.
The manual override lever clicks back and forth with audible sound each time tripper moves on-off lever.

Move manual override back and forth and it will turn Load on and off.
Override should snap crisp and clean.

To set timer, lift and rotate dial until current time lines up with stationary silver pointer.
Stationary silver pointer is pointed at 6:00.

How to set up intermatic t104m to work with two speed motor


T104 cannot be easily set up to handle 2-speed motors
You need T106 timer with NO NC terminals.

Or you can use the T104 to control relay with NO NC terminals... relay would need 240 Volt coil. Problem is most relays with NO NC terminals are 120 Volt coil or rated too low amperage for motor.

Or move T104 clock motor wires to A and 1... connect 240Volt power to A and 1... then terminals 3-4 are dry and can be used to control any voltage relay coil (120 Volt for example).
When T104 is ON, then relay uses NC terminals to send power to low speed. When T104 is OFF, then relay uses NO terminals to send power to high speed.
Buying T106 timer is probably cheaper and simpler.

What position is lever on intermatic pool timer t104p3 for timer to work?


Lever automatically moves back and forth as trippers pass.
Move lever to ON position, move to the right.
If timer dial is not rotating, then check wiring, or replace clock motor:
If timer worked before and stopped working, but dial still rotates, the trippers are worn down, replace trippers:

The "little gray box"


You need 2 ON trippers and 2 OFF trippers.
Part number 156T1976A sold at WW Grainger etc.

1) Copy following links for WH40 little grey box Intermatic timer operation and resources:
http://waterheatertimer.org/pdf/How-to-operate-and-set-T104-timer.pdf
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T104

2) WH40 timer is identical to T104, same replacement parts, same operation, same wiring options, except the grey box timer has override lever that sticks out of box. Both WH40 and T104 have override levers, the WH40 override can be moved without opening box door.
This allows you to use the WH40 as ordinary on-off switch if the trippers are removed from dial.

T104 intermatic stationary pointer moved to the side


T104 pointer is stationary and is supposed to be pointed straight down, assuming timer is installed in vertical position.
Move pointer until it points straight down and apply bit of super glue, or just remember correct location.

When setting my timers should the manual switch be left in the on or off position?


Either position is fine.
The override is not permanent ON or OFF since it moves back and forth when trippers pass.
The trippers push a lever back and forth that opens and closes electrical circuit.
When the lever moves back and forth, it also clicks the override back and forth with audible sound.
If the timer is ON, you can move the override to OFF.
When the next ON tripper rotates around, it will move the override back to ON.
So the override just temporarily overrides the timer function.
