Benelli Imperiale 400 - Owner's Manual > Spark plug

Clear away carbon deposit on the spark plug with small metal wire brush or spark plug cleaner during inspection period noted in the maintenance schedule. Readjust the electrode gap of spark plug with feeler gauge and keep the gap between 0.60.7 mm.

Replace the sparking plug for each 6000 km.

Type of Spark Plug: NGK(BR7ES) / NGK(CR7HSA)

Do not Screw the spark plug too tight to avoid damaging the threads of cylinder cover.

Don't let the foreign objects fall into the engine through spark plug hole during dismounting.

CATALYTIC CONVERTER

In order to meet the requirements of environmental emission, the muffler of the motorcycle is equipped with catalytic converter.

The catalytic converter contains precious metals as the catalyst, which will transform the hazardous substances in the exhaust gas, including carbon monoxide, hydrocarbon and nitrogen oxide into non-toxic carbon dioxide, water and nitrogen through chemical reaction.

Since the catalytic converter is very important, the defective catalytic converter will pollute the air and damage the performance of the engine, if the replacement is needed, please use the genuine parts or entrust the distributors to replace.

Caution:

The catalytic converter is at high temperature area, please do not touch.

BATTERY

Battery is under the seat cushion. The battery for the motorcycle is maintenance free type. For the new motorcycle, please ask the dealer of the company to fill electrolyte into the battery for you. It is not necessary to refill electrolyte in the future.

If you have to take out the battery for inspection, please follow these steps:

a. Shut off power switch of the motorcycle;

b. Remove the seat cushion;

12V8Ah (YTX9-BS) MF (Maintenance Free) Battery

d. Take down the negative terminal (-) first, and then the positive terminal (+);

e. Take out the battery gently.

Install the battery in the reverse order of removal.

Attention:

Connect correctly the battery wires when the battery is re-installed. The red wire shall be connected with the positive terminal (+); and black wire shall be connected to the negative terminal (-). If the wires are wrongly connected, it may damage the electrical system and the battery.

Power switch (key) shall be shut off while inspecting or replacing battery.

Please operate on the following requirements for the first use:

Remove the sealing paper on the battery. Inject specially supplied electrolyte into the battery and put on the battery sealing plug. Leave it for 30 minutes for full chemical reaction and then you can use the battery.

For the new battery, initial charge after electrolyte filling will extend its service life. This operation shall be performed by your local dealers.

Connect the wire polarities correctly. Positive wire (red) shall be connected with the positive terminal (+); and negative wire (black) to the negative terminal (-). Tighten terminal bolts. Clean frequently the erosive substances on the terminals with a wire brush while in use.

Please operate according to the following requirements while filling electrolyte into the maintenance-free battery:

a. Place vertically the battery on a horizontal plane and remove the sealing tape.

b. Take out the electrolyte from the plastic bag. Open its cover strip and use it as filling plug for the battery.

Attention: Please do not tear or puncture the sealing tape on the filling port.

The cover strip can be kept as filling plug for the battery.

c. Lift the electrolyte container upside down vertically and align the six filling ports of the container with the six filling ports on the battery. Pull downward hard the electrolyte container so as to puncture the sealing tape on the filling ports of electrolyte container. Electrolyte thus flows from the container to the battery. Check the three filling pipes on both sides. At least there is one pipe that has bubbles coming out on each side, which means that electrolyte filling begins normally. Attention: Please be sure not to tilt the container, or electrolyte filling may be interrupted.

d. When you are sure that there is at least one pipe that has bubbles coming out on each side (three pipes on each side), leave it there and keep the filling process over 20 minutes.

If there is no pipe that has bubbles coming out on each side, tap slightly two to three times the bottom of the electrolyte container and check again if there is at least one pipe that has bubbles coming out on each side (The electrolyte cannot be taken down now).

e. When the electrolyte has completely owed through, tap the container bottom several times to drain residual electrolyte; and then slowly pull out the electrolyte container.

f. The six sealing plugs on the cover strip align respectively to the six filling ports on the battery. Make sure the ends of the six sealing plug has inserted into the filling ports on the battery; press them hard into the ports till the cover strip makes a plane with the top surface of the upper part of the battery.

After completion of electrolyte filling, please do not pull out the cover strip or fill water, electrolyte or other liquid.

Pay attention to the following matters while replacing the battery.

Before replacing the battery, please first determine the model of motorcycle and check if both batteries are of the same type. During motorcycle design, the battery specifications are considered as the best choice. If a battery of a different model is used, it may affect performance and life time of the motorcycle, and possibly causes electrical failure.

If the motorcycle will not be used for a long time, please remove the battery and charge it once a month.

Warning: Battery will produce explosive gases when chemical reaction occurs in the battery.

Keep the battery away from re, spark and high temperature places.

The battery is filled with sulfuric acid (electrolyte). Electrolyte is poisonous substance.

Please keep it out of reach of children.
