7.2.8. The blocking switch of coupling

GENERAL INFORMATION

The switch is intended for blocking of start-up of the engine if the pedal of coupling is not squeezed out.

The blocking switch of coupling (it is specified by an arrow) is mounted on an arm in the top part of a pedal, fastens 2 nuts by which its situation concerning a pedal is regulated.

Check, adjustment and replacement

PERFORMANCE ORDER
1. Be convinced that the engine is started only at the squeezed-out pedal.
2. Otherwise the switch is faulty. Check tension presence on the switch.
3. If tension is, check connection with mass of the second conclusion of the switch at the released pedal.
4. If the chain of the switch is faulty, eliminate malfunction and again check the switch.
5. If the chain is serviceable, check short circuit of contacts of the switch. At the pressed pusher contacts should become isolated, at the released pusher contacts are disconnected. Otherwise the switch replace.

SWITCH OF THE UNBLOCKING OF START

This switch provides engine start without pressing a coupling pedal that can be necessary in the complicated traffic conditions (for example uphill). The button of the switch is on the left side on the forward panel, the canceling switch is a part of the blocking switch of coupling.

Check, adjustment and replacement

PERFORMANCE ORDER
1. Transfer the button to the situation Off and присоедиените (+) – an ohmmeter conclusion to a conclusion 2 switches, and (-) – an ohmmeter conclusion – to a conclusion 1. Between these conclusions the ohmmeter should show a gap.
2. In the same position of the button присоедиените (+) – an ohmmeter conclusion to a conclusion 3 switches, and (-) – an ohmmeter conclusion – to a conclusion 1. Between these conclusions the ohmmeter should show a gap. Chains also should not be between conclusions 2 and 3.
3. Submit a food +12В on a conclusion 3, and (-) batteries attach to a conclusion 1 (+) – a conclusion of an ohmmeter attach to a conclusion 2 switches, and (-) – an ohmmeter conclusion – to a conclusion 1. At the pressed button (in the situation On) between these conclusions the ohmmeter should show a chain.
4. When the switch is in the situation Off between these conclusions there should be a gap.
5. Disconnect the battery and transfer the switch to the situation On. Between conclusions 1 and the 2nd ohmmeter should show a gap.
6. If results of checks differ from described above, the switch replace.
7. For adjustment release a lock-nut and rotate the switch to a pusher vystupaniye on 7,5–8,3 mm concerning a lock-nut.
8. For replacement remove the bottom facing, disconnect the socket, unscrew a lock-nut and remove the switch. Installation is carried out upside-down.
