GENERAL INFORMATION
HYDROGEN GAS AND BATTERY ELECTROLYTE
DANGER
The battery electrolyte is a toxic, caustic substance containing sulfuric acid and thus able to cause
severe burns in case of contact.
Wear close-fitting gloves and protective clothing when handling this fluid.
If any battery fluid gets on your skin, rinse the affected area with abundant fresh water.
Take special care to protect the eyes; even a very small amount of battery fluid can cause blindness. If
battery fluid comes in contact with the eyes, flush with abundant water for fifteen minutes and contact
an eye specialist immediately.
If battery fluid is swallowed accidentally, drink abundant water or milk. Seek medical attention
immediately and keep drinking milk of magnesia or vegetable oil in the meantime.
The battery gives off explosive gases. Keep the battery well away from any sources of ignition, such
as flames, sparks, or any heat sources.
Make sure the area is well ventilated when servicing or refilling the battery.
KEEP AWAY FROM CHILDREN.
Battery fluid is corrosive.
Avoid spillage. Take special care not to spill battery fluid on plastic parts.
Ensure that the electrolyte fluid you are using is the suitable type for your battery.
GENERAL PRECAUTIONS AND INFORMATION
Follow these instructions closely when repairing, disassembling or reassembling the motorcycle or its components.
DANGER
Using bare flames is strictly forbidden when working on the motorcycle. Before servicing or
inspecting the motorcycle: stop the engine and remove the key from the ignition switch; allow the
engine and exhaust system to cool down; where possible, lift the motorcycle using adequate
equipment placed on firm and level ground. Pay particular attention to any parts of the engine or
exhaust system which may still be hot to the touch to avoid burns.
Never put mechanical parts or other vehicle components in your mouth when you have both hands
busy. None of the motorcycle components are edible. Some components are harmful to the human
body or toxic.
If not expressly indicated otherwise, for the reassembly of the units repeat the disassembly
operations in reverse order. Where a procedure is cross-referred to relevant sections in the manual,
proceed sensibly to avoid disturbing any parts unless strictly necessary. Do not use polishing pastes
on matt paints.
Never use fuel instead of solvent to clean the motorcycle.
Do not clean rubber or plastic parts or the seat with alcohol, gasoline or solvents. Use only water and
mild soap.
Always disconnect the battery negative (-) lead before soldering any electrical components.
When two or more persons service the same motorcycle together, special care must be taken to avoid
personal injury.
For further details, see (DANGEROUS ELEMENTS).
BEFORE REMOVING ANY COMPONENTS
• Clean off all dirt, mud, and dust and clear any foreign objects from the vehicle before disassembling any
components.
• Use the model-specific special tools where specified.
DISASSEMBLING THE COMPONENTS
- Never use pliers or similar tools to slacken and/or tighten nuts and bolts. Always use a suitable wrench.
- Mark the positions of all connections (hoses, wiring, etc.) before disconnecting them. Identify each connection using
a distinctive symbol or convention.
- Mark each part clearly to avoid confusion when refitting.
- Thoroughly clean and wash any components you have removed using a detergent with low flash point.
- Mated parts should always be refitted together. These parts will have seated themselves against one another during
running as a result of normal wear and tear and should never be mixed up with other similar parts when refitting.
- Certain components are matched-pair parts and should always be replaced as a set.
- Keep away from heat sources.
