1-2 GENERAL INFORMATION

WARNING/CAUTION/NOTICE/NOTE

Please read this manual and follow its instructions carefully. To emphasize special information, the symbol

and the words WARNING, CAUTION, NOTICE and NOTE have special meanings. Pay special attention to

the messages highlighted by these signal words.



Indicates a potential hazard that could result in death or injury.



Indicates a potential hazard that could result in motorcycle damage.

Indicates a potential hazard that could result in motorcycle or equipment damage.

NOTE:

Indicates special information to make maintenance easier or instructions clearer.

Please note, however, that the warnings and cautions contained in this manual cannot possibly cover all

potential hazards relating to the servicing, or lack of servicing, of the motorcycle. In addition to the WARN-

INGS, CAUTIONS and NOTICES stated, you must use good judgement and basic mechanical safety princi-

ples. If you are unsure about how to perform a particular service operation, ask a more experienced

mechanic for advice.

GENERAL PRECAUTIONS



* Proper service and repair procedures are important for the safety of the service mechanic and

the safety and reliability of the motorcycle.

* When 2 or more persons work together, pay attention to the safety of each other.

* When it is necessary to run the engine indoors, make sure that exhaust gas is forced out-

doors.

* When working with toxic or flammable materials, make sure that the area you work in is well-

ventilated and that you follow all of the material manufacturer’s instructions.

* To avoid getting burned, do not touch the engine, engine oil, radiator and exhaust system

until they have cooled.

GENERAL INFORMATION 1-3

* Never use gasoline as a cleaning solvent.

* After servicing the fuel, oil, water, exhaust or brake systems, check all lines and fittings

related to the system for leaks.

* If parts replacement is necessary, replace the parts with Suzuki Genuine Parts or their equiva-

lent.

* When removing parts that are to be reused, keep them arranged in an orderly manner so that

they may be reinstalled in the proper order and orientation.

* Be sure to use special tools when instructed.

* Make sure that all parts used in reassembly are clean. Lubricate them when specified.

* Use the specified lubricant, bond, or sealant.

* When removing the battery, disconnect the negative cable first and then the positive cable.

* When reconnecting the battery, connect the positive cable first and then the negative cable,

and replace the terminal cover on the positive terminal.

* When performing service to electrical parts, if the service procedures do not require use of

battery power, disconnect the negative cable from the battery.

* When tightening the cylinder head or case bolts and nuts, tighten the larger sizes first.

Always tighten the bolts and nuts diagonally from the inside toward outside and to the speci-

fied tightening torque.

* Whenever you remove oil seals, gaskets, packing, O-rings, locking washers, self-locking

nuts, cotter pins, circlips and certain other parts as specified, be sure to replace them with

new ones. Also, before installing these new parts, be sure to remove any left over material

from the mating surfaces.

* Never reuse a circlip. When installing a new circlip, take care not to expand the end gap larger

than required to slip the circlip over the shaft. After installing a circlip, always ensure that it is

completely seated in its groove and securely fitted.

* Use a torque wrench to tighten fasteners to the specified torque. Wipe off grease and oil if a

thread is smeared with them.

* After reassembling, check parts for tightness and proper operation.

* To protect the environment, do not unlawfully dispose of used motor oil, engine coolant and

other fluids: batteries and tires.

* To protect Earth’s natural resources, properly dispose of used motorcycle and parts.
