When the electric locomotive is working, if the wheel is slipping, the operator must:

• shift the main gear to '1' and use the sand system.

• shift the reverse gear to position 'O' and then shift the main gear.

• shift the main gear to the 'highest' number and use the sand system.

• shift the main gear to the 'highest' number and use the brake system.

Before operating the electric locomotive, the operator must check:

• oil and grease.

• the battery and control unit.

• the engine, signals, and brakes.

• the mechanical and electrical parts.

When the battery locomotive is running in normal working mode, to stop the locomotive, just:

• shift the main gear to position 'O' and use the mechanical brake.

• use the reverse brake and mechanical brake.

• shift the reverse gear to position 'O' and use the mechanical brake.

• shift the main gear to position 'O' and use the electric brake.

When wanting to change the working direction of the electric locomotive, the operator must:

• shift the main gear to position 'O' and then shift the reverse gear.

• turn the reverse gear handle to position 'O' and then shift the main gear.

• simultaneously turn the reverse gear and main gear.

• brake, then turn the main gear handle to position 'O'.

When the electric locomotive is working, if the wheel is slipping, the operator must:

• shift the main gear to '1' and use the sand system.

• shift the reverse gear to position 'O' and then shift the main gear.

• shift the main gear to the 'highest' number and use the sand system.

• shift the main gear to the 'highest' number.

When the electric locomotive is working normally, the operator wants to stop the locomotive but is prohibited from:

• using the reverse gear.

• cutting off the power supply.

• simultaneously using the mechanical brake and electric brake.

• using the brake before shifting the main gear to position 'O'.

When adjusting the mechanical brake of the electric locomotive, the number of steering wheel turns to brake the locomotive safely is:

• 2 to 2.5 turns.

• 2.5 to 3 turns.

• less than 1.5 to 2 turns.

• 1 to 1.5 turns.
