1 Always perform service procedures in a well-ventilated area to jrevent a build-up of fumes.

! Never work in a building containing a gas appliance with a pilot light, orany other form of naked flame. Ensure that there are no naked light iulbs or any sources of flame or sparks nearby.

J Do not smoke (or allow anyone else to smoke) while in the vicinity of jasoline (petrol) or of components containing gasoline (petrol). temember the possible presence of vapor from these sources and me well elear before smoking.

i Check all electrical equipment belonging to the house, garage or wrkshop where work is being undertaken (see the Safety first! section ifthis manuał). Remember that certain electrical appliances such as Mis, cutters, etc, create sparks in the normal course of operation and must not be used near gasoline (petrol) or any component containing it. Again, remember the possible presence of gasoline (petrol) fumes before using electrical equipment.

5 Always mop up any spilt fuel and safely dispose of the shop towel or rag used.

j Any stored gasoline (petrol), or any drained off during servicing iiork, must be kept in sealed containers that are suitable for holding jasoline (petrol), and clearly marked as such; the containers themselves Muld be kept in a safe place. Notę that this last point applies equa!ly to iiefuel tank if removed from the machinę; also remember to keep its filier cap closed at all times.

? The fuel system consists of the fuel tank, with its filier cap and slated vent pipes, the fuel pump (where applicable) and filters. Notę that on California models, this includes the Evaporative Emission Control System components.

3 Read the Safety first! section of this manuał carefully before starting

«ork.

i Owners of machines used in the US, particulariy California, should ■ote that their machines must comply at all times with Federal or State egislation governing the permissible levels of noise and of pollutants such as unburnt hydrocarbons, carbon monoxide etc, that can be emitted by those machines. All vehicles offered for sale must comply with legislation in force at the datę of manufacture and must not subsequently be altered in any way whicn will affect their emission of noise or of pollutants.

10 In practice, this means that adjustments may not be madę to any part of the fuel, ignition or exhaust systems by anyone who is not authorized or mechanically qualified to do so, or who does not have the tools, equipment and data necessary to properiy carry out the task. Also if any part of these systems is to be renewed it must be replaced only by the genuine Honda components or by components which are approved under the relevant legislation, and the machinę must never be used with any part of these systems removed, modified or damaged.

4 Fuel tank: removal, inspection and installation

Refer to photos 4.2a, 4.2b, 4.4a, 4.4b, 4.4c, 4.4d and Figs. 4.1 and 4. 2. Warning: Gasoline ipetroi) is extreme/y flammaole, especia/ly when in the form of vapour.
