SERVICE PRECAUTIONS
nMake sure to install new gaskets, O-rings,circlips, cotter pins, etc. whenreassembling.
nWhen tightening bolts or nuts, begin withlarger-diameter to smaller ones at severaltimes, and tighten to the specified torquediagonally.
n Use genuine parts and lubricants.
nWhen servicing the motorcycle, be sure touse special tools for removal andinstallation.
n After disassembly, clean removed parts.Lubricate sliding surfaces with engine oilbefore reassembly.
n Apply or add designated greases andlubricants to the specified lubricationpoints.
n After reassembly, check all parts forproper tightening and operation.
nWhen two persons work together, payattention to the mutual working safety.
n Disconnect the battery negative (-) terminalbefore operation.nWhen using a spanner or other tools, make
sure not to damage the motorcycle surface.
n After operation, check all connectingpoints, fasteners, and lines for properconnection and installation.nWhen connecting the battery, the positive
(+) terminal must be connected first.n After connection, apply grease to the
battery terminals.n Terminal caps shall be installed securely.

n If the fuse is burned out, find the cause andrepair it. Replace it with a new oneaccording to the specified capacity.
n After operation, terminal caps shall beinstalled securely.
nWhen taking out the connector, the lock onthe connector shall be released beforeoperation.
n Hold the connector body when connectingor disconnecting it.n Do not pull the connector wire.
n Check if any connector terminal is bending,protruding or loose.
n The connector shall be insertedcompletely.n If the double connector has a lock, lock
it at the correct position.n Check if there is any loose wire.
n Before connecting a terminal, check fordamaged terminal cover or loose negativeterminal.
n Check the double connector cover forproper coverage and installation.
n Insert the terminal completely.n Check the terminal cover for proper
coverage.n Do not make the terminal cover opening
face up.
n Secure wire harnesses to the frame withtheir respective wire bands at thedesignated locations.Tighten the bands so that only theinsulated surfaces contact the wireharnesses.

n After clamping, check each wire to makesure it is secure.
n Do not squeeze wires against the weld orits clamp.
n After clamping, check each harness to makesure that it is not interfering with anymoving or sliding parts.
nWhen fixing the wire harnesses, do notmake it contact the parts which willgenerate high heat.
n Route wire harnesses to avoid sharp edgesor corners. Avoid the projected ends ofbolts and screws.n Route wire harnesses passing through the
side of bolts and screws. Avoid theprojected ends of bolts and screws.
n Route harnesses so they are neitherpulled tight nor have excessive slack.
n Protect wires and harnesses with electricaltape or tube if they contact a sharp edge orcorner.
nWhen rubber protecting cover is used toprotect the wire harnesses, it shall beinstalled securely.
n Do not break the sheath of wire.n If a wire or harness is with a broken sheath,
repair by wrapping it with protective tapeor replace it.
nWhen installing other parts, do not press orsqueeze the wires.
Do not pulltoo tight

n After routing, check that the wire harnessesare not twisted or kinked.
nWire harnesses routed along with handlebarshould not be pulled tight, have excessiveslack or interfere with adjacent orsurrounding parts in all steering positions.
nWhen a testing device is used, make sure tounderstand the operating methodsthoroughly and operate according to theoperating instructions.
n Be careful not to drop any parts.
nWhen rust is found on a terminal, removethe rust with sand paper or equivalentbefore connecting.
