Diesel Starting note:

Before starting the inspection: In order to ensure that the rollers can safely and efficiently for your service, or work cycle of each working day before, it is necessary to conduct the following checks. If necessary, repairs and maintenance that should be added lubricants. At this point, as far as possible to stop the roller on the ground level.

Inspection:whole machine and diesel is an unusual situation and pipeline ministries Box whether oil spills, each part of the fastening bolts connecting nut, check whether the battery intact; Shousha Che check the validity;

Inspection of the engine oil.

Open air filter dust discharge valve and the dust emission.

A pinch of fuel pre-filter (with oil and water separator) below the valve Cypriots, will discharge water out.

Inspection of fuel oil.

Inspection of the cooling water level. Ning, vice-Xuansai under water tanks, cooling fluid outflow due, or in time to add coolant, tightened immediately after the inspection. Canadian anti-rust solution should not be too cold, fill two minutes after starting the engine stopped functioning while, supplemented and time, this can prevent the phenomenon of false or above.

Starting attention should be paid

Bian Sugan ensure that the neutral gear position on the "O".

Ensure that the inverted-handle in place on the "O".

Banqi Shousha Che to position "|", check roller.

Will pull the engine throttle to handle slightly higher than the idle position (800 r / min).

Bandong power switch.

Clockwise rotation ignition switch to 90 degrees, connected to the power circuit, the observation of the instruments and warning lights are normal.

Press the start button to start the engine, when launched after the success of the rapid release, each time you start no more than 30 s, if not start, about 2 min should pause for a second time after the start. Three could not be activated when the reasons for inspection. In order to facilitate the start, riding under the first clutch pedal, undocked from the main clutch, to be launched after the release pedal to clutch engagement (to the attention of the Office of the speed throttle). Roller will not run in the main clutch pedal, such as the need to brake, in the engagement and release again when the engine speed to not higher than that of 1300 / points, or clutch will wear quickly.

Engine start, the first manipulation of the throttle, the engine speed gradually increased to 1000 r / min functioning 5-10 min to raise the temperature, at this time voltage meter, oil pressure gauge, engine thermometers, barometers indicators are pointing to normal.

When the normal instrument in the film, you have to bring load.

Note: For roller long-term parking or replace the engine oil after the start-up method reference to the engine specification.

Caution should be taken when running roller

Diesel set to handle medium-speed throttle position (to be started after the roller-to high-speed).

Brake and cut off the clutch pedal power.

By walking or pushing direction after Ladao with handles.

According to the need to identify the roller speed, Bandong Bian Sugan need to Shift, a block for the work efficiency, two guards and speed of work and transport, the three guards for the transportation speed, allowing only a good straight road worthiness.

Wrench under braking.

The release of clutch pedal.

Roller is walking forward or backward, at this time should first try foot brake is sensitive. Note: stamping on the foot brake, not excessive force, should be careful not to forget the first clutch pedal.

Moment of the steering wheel in situ try, hydraulic steering gear is effective and reliable.

After the engine throttle handle to pull the engine reached full swing.

Note: for speed or when the road roller to first reduce the engine speed so that the roller speed decreased speed or exchange forward, we must brake main clutch, it will happen early gear wear or break. And then push light or light-speed or inverted-handle, the next to complete the meshing of gears. When inverted-manipulation handle rapid action to smooth, do not force excessive. Pause on the first middle of a period of time (about 10 seconds) and lower rollers to go forward or moving after the inertia, and then inverted-Bandong in place to handle and to ensure that the meshing gears entirely.
Uphill downhill, the speed of a moving block, transmission should be carried out before the uphill or downhill (no shift in the ramp)
Bian Sugan uphill, may not be placed in neutral gear, shall not be undocked from clutch.

Emergency brake:brake clutch pedal. When using the foot brake, do not force excessive, emergency situations can also tighten Shousha Ju. To avoid high-speed roller under the emergency brake, or else they would reduce the braking system of life.

The roller :

A left turn signal or a right turn signal switch, corresponding to bright lights.

When the high-speed roller block (3 block), should handle the manipulation of the accelerator and reduce speed roller.

Turn left (or right) turn the steering wheel, the roller change.

Note: The operation to be careful to prevent the roller rear-wheel-drive or a roadbed Yahuai road kerbs.

Parking

Bandong to handle the throttle position in the speed and lower roller speed.

In the clutch pedal, will be inverted with handles on the median, Bian Sugan in neutral gear, release the clutch pedal.

Pulling up the grip brake.

Gradually reduce engine speed to idling running 3-5 minutes, reduce the engine temperature.

And then pulled up off the door, close the engine.

Counter-clockwise to start the ignition switch in situ, cut off the circuit.

Close the power switch.

Note: If roller parked on the ramp, the next round should be to put stones or wood to prevent sliding.
