SAFETY WHILE WORKING

The procedures given in this manual are those

recommended by Yamaha to be followed by

Yamaha dealers and their mechanics.

FIRE PREVENTION

Gasoline (petrol) is highly flammable.

Petroleum vapor is explosive if ignited. Do not

smoke while handling gasoline (petrol), and

keep it away from heat, sparks, and open

flames.

VENTILATION

Petroleum vapor is heavier than air and if

inhaled in large quantities will not support life.

Engine exhaust gases are harmful to breathe.

When test-running an engine indoors, maintain

good ventilation.

SELF-PROTECTION

Protect your eyes with suitable safety specta-

cles or safety goggles when using compressed

air, when grinding or when doing any operation

which may cause particles to fly off.

Protect hands and feet by wearing safety

gloves and protective shoes if appropriate to

the work you are doing.

OILS, GREASES AND SEALING FLUIDS

Use only Genuine Yamaha oils, greases and

sealing fluids or those recommended by

Yamaha.

Under normal conditions of use, there should

be no hazards from the use of the lubricants

mentioned in this manual. However, safety is

all-important, and by adopting good safety

practices, any risk is minimized. A summary of

the most important precautions is as follows:

1. While working, maintain good standards of

personal and industrial hygiene.

2. Clothing which has become contaminated

with lubricants should be changed as soon

as practicable and laundered before further

use.

GENERAL INFORMATION

1-2

1GEN

INFO

3. Avoid skin contact with lubricants; do not,

for example, place a soiled wiping-rag in

one’s pocket.

4. Hands, and any other part of the body

which have been in contact with lubricants

or lubricant-contaminated clothing, should

be thoroughly washed with hot water and

soap as soon as practicable.

5. To protect the skin, the application of a suit-

able barrier cream to the hands before

working is recommended.

6. A supply of clean lint-free cloths should be

available for wiping purposes.

GOOD WORKING PRACTICES

1. The right tools

Use the special tools that are designed to

protect parts from damage. Use the right

tool in the right manner – don’t improvise.

2. Tightening torque

Follow the torque tightening instructions.

When tightening bolts, nuts and screws,

tighten the larger sizes first, and tighten

inner-positioned fasteners before outer-

positioned ones.

3. Non-reusable items

Always use new gaskets, packings,o-rings,

oil seals, split-pins and circlips, etc. on

reassembly.

DISASSEMBLY AND ASSEMBLY

1. Clean parts with solvent and compressed-

air on disassembling them.

2. Oil the contact surfaces of moving parts on

assembly.

3. After assembly, check that moving parts

operate normally.

4. Install bearings with the manufacturer’s

markings on the side exposed to view and

liberally oil the bearings.

Do not use compressed air to spin the bear-

ings dry. This causes damage to the bearing

surfaces.

5. When installing oil seals, apply a light coat-

ing of water-resistant grease to the outside

diameter.

CAUTION:

SPECIAL TOOLS

Use of the correct special tools recommended

by Yamaha will aid the work and enable accu-

rate assembly and tune-up. Improvisations and

use of improper tools can cause damage to the

equipment.

NOTE:

• For U.S.A. and Canada, use part numbers

starting with “J-”, “YB-”, “YM-”,“YS-”, “YU-” or

“YW-”.

• For other countries, use part numbers starting

with “90890-.”
