9. PRECAUTIONS

The following points are to be adhered, when

starting the Starter Motor :

1) Ensure that all Electrical Positive & Negative

Connections to Starter motor are in good Condition.

2) Press the Start button firmly and release as soon

as the engine fires.

3) If the engine does not fire at once allow it to rest,

before operating the Starter switch again.

4) If the engine does not start, ascertain the cause

and do not run down the battery by keeping the

Starter button ON.

5) Do not operate the Starter when the engine is

running. Otherwise serious damage could occur

both to the Starter pinion and the flywheel ring gear

teeth.

10. ROUTINE CHECKS

1) Ensure that the starter motor mounting bolts to

the engine are securely fastened for proper earthing.

2) Cheek electrical connections are clean and tight.

3) Cables should be examined for fractures

particularly where the strands enter the terminal

lugs.

4) Inspect fixing bracket for any cracks.

DO’s

1) Ensure that all electrical connections in the circuit

including the battery are clean and secure.

2) Observe correct polarity. i.e. connect negative to

negative and positive to positive.

3) For earth return system, check the cable

connection from Starter to earth and battery

negative terminal to earth point.

4) Ensure minimum cable length for starter circuit &

battery.

5) The total resistance of the starter circuit including

that of return path and junctions should not exceed

0.002 ohm 20°C.

6) Themain feed cable should be supported to prevent

the cable weight and vibrations from coming on to

the electrical terminals.

7) While washing the vehicle with high pressure gun

starter motor should be suitably protected.

8) Maintain battery in good condition by checking

charge level and electrolyte specific gravity

9) Ensure there is enough fuel in the tank to avoid air

lock.

DONT’S

1) Do not operate the starter motor when the engine

is running as this could result in damaging the

starter motor pinion and flywheel ring gear

2) Do not crank continuously. If the engine does not

fire immediately, allow sometime to cool the starter

motor before cranking again.

3) If still the engine does not start, ascertain the cause

and do not drain the battery by cranking the starter

motor

4) Do not inch (move) the vehicle using starter motor.

5) Do not subject the starter motor to continuous oil/

water drip.

6) Do not accelerate immediately after a start.

(Allow the engine idle rpm to stabilize).
