Familiarizing with key controls of a road roller

1.     Ignition Switch

The ignition switch is used to start and stop the engine of the road roller. It is typically located on the control panel or dashboard. To start the engine, the operator turns the ignition switch to the “ON” position, allowing electrical power to flow to the engine. Once the engine starts, the switch is released to the “RUN” position, keeping the engine running. To stop the engine, the operator turns the ignition switch to the “OFF” position, cutting off the power supply.

2.     Throttle Control

The throttle control regulates the engine speed and power output. It is usually a lever or knob located near the operator’s seat. By adjusting the throttle control, the operator can increase or decrease the engine speed, which directly affects the rotation speed of the roller’s drum or wheels. Increasing the throttle control will raise the engine speed and provide more power for compacting or moving material, while decreasing it will lower the engine speed and reduce the roller’s speed.

3.     Starter Button

The starter button is used to engage the starter motor and initiate the engine’s starting sequence. It is typically located near the ignition switch or on the control panel. When the operator turns the ignition switch to the “START” position and presses the starter button, an electrical current is sent to the starter motor, which then cranks the engine to start it. Once the engine is running, the operator releases the starter button.

4.     Hydraulic Controls

Road rollers utilize hydraulic systems to control various functions, such as steering, vibration, and compacting force. The hydraulic controls consist of levers, pedals, or buttons located on the control panel or within easy reach of the operator. The specific controls may vary depending on the roller model, but they typically include functions like steering control for turning the roller, vibration control to activate or deactivate the drum vibration, and compacting force control to adjust the pressure applied by the roller’s drum or wheels.
