1) Attach the contactor operating lever to the fl at section of the contactor
shaft using two 1/4-20 in. (M6 x 1.0) hex-head cap screws with two 1/4 in.

The contactor operating lever is threaded for the supplied

(M8 x 1.25) hex nut at least 2 in. (50 mm) down the rod. Place one
5/16 in. (M8) lock washer over the nut.
3) Insert a 5/16–18 (M8 x 1.25) hex nut into the clevis of the door
interlock lever (see Figure 2.17).
