2 Starting by Manual Starting Switch Starting by Manual Starting Switch

Under this, a paddle is installed near the engine, by pressing which the electrical circuit is completed. This causes
the electric motor to rotate and start the engine. On releasing the pedal, the circuit is broken and the motor stops.
Precautions: To start the engine through manual starting switch, the following precautions should be taken:
• There should not be any kind of greasy substance on the hand
• The battery should be fully charged.
• The wiring of the vehicle/engine should not be broken anywhere.
• Spark plugs should be carbon free.

3 Starting by Push
Motor vehicles can also be started with the help of push. For this, after engaging the rider, we press the clutch
pedal and as soon as the clutch pedal is released while pushing, the engine starts.

Precautions to jump start the engine:
Precautions should be taken-
• Balance should be maintained while pushing the vehicle.
• One should not put unnecessary effort into pushing.

• One should not try to push minors.
• There should be necessary air in the wheels of the vehicle while pushing.
4 Starting by Handle
In many engines of motor vehicles, the handle is stuck in the groove cut in the driving pulley. The engine starts
even by turning it.
Precautions: The following precautions should be taken to start the engine using the handle:
• Hands should be kept completely grease free.
• The handle should be properly seated in the groove.
• Balance should be maintained while applying the handle to the vehicle.

• The handle should not be deformed.
5 Starting by Flywheel
To start a single cylinder stationary engine, the flywheel is rotated by placing the starting handle in its flywheel
and at the same time the compression lever of the engine is pressed. As soon as the flywheel starts rotating, the
compression lever is lifted, thus starting the engine.
Precautions: To start the engine by flywheel, the following precautions should be taken care of-
• Keep hands completely grease free.

• Do not remove the de-compression lever when the flywheel is running at low speed.
• Never try to touch the rotating flywheel.
6 Starting by Rope
Usually, a rope is wrapped around the pulley of a tractor and the engine is pulled by pulling it. This method is also
used for Shree-Wheeler or Auto etc.
Precautions: The following precautions should be taken to start the engine by rope-
• The rope should be wound on the pulley in a suitable manner.
• Hands should be completely grease free.
• Maintain balance while pulling the rope.
• Do not use weak rope in this process under any circumstances.
• Fix the knot of the rope properly in the groove of the pulley, so that any kind of accident can be avoided.
