Assembling way of light circuit
1. Disconnect connector A, and then remove LED circuit B. (Refer to Fig. 1 and 2 in page 2.)
2. Separate insulated terminal C from switch. (Refer to Fig. 2 in page 2.)
3. Detach orange colored lead wire from the root of the insulated terminal C (Refer to Fig. 2 in page 2.)
4. Strip the orange colored lead wire D in 7mm or 8mm. (Refer to Fig. 2 in page 2.)
5. After clamping a stripped end of orange colored lead wire E of new type light circuit and the stripped lead wire D with
insulated terminal RBV1.25-3.5T (Part No. 654037-5), reassemble it to switch terminal. (Refer to Fig. 3 and 4 in page 3.)
6. Connect the connector Fa of the new type light circuit with the connector Fb of lead wire from switch as Fig 4 in page 3.
7. Set LED circuit G of the new type light circuit in place as Fig. 3 in page 3.
8. Install a part for afterglow function H into motor housing as Fig. 4 in page 3. And then fix housing R with housing L.
Operation check of a light with afterglow function
1. Check that the light turns on when pulling a trigger of switch.
2. Check that the light continues to illuminate for about 10 seconds after releasing the trigger.
