SAFETY WHILE WORKING
SAFETY WHILE WORKING
To prevent and accident or injury and to
ensure quality service, follow the safety proce-
dures provided below.
FIRE PREVENTION
Gasoline is highly flammable.
Keep gasoline and all flammable products
away from heat, sparks, and open flames.
VENTILATION
Gasoline vapor and exhaust gas are heavier
than air and extremely poisonous. If inhaled in
large quantities they may cause loss of con-
sciousness and death within a short time.
When test running an engine indoors (e.g., in a
water tank), be sure to do so where adequate
ventilation can be maintained.
SELF-PROTECTION
Protect your eyes by wearing safety glasses or
safety goggles during all operation involving
drilling and grinding, or when using an air com-
pressor.
Protect your hands and feet by wearing protec-
tive gloves or safety shoes when necessary.
PARTS, LUBRICANTS, AND
SEALANTS
Use only genuine Yamaha parts, lubricants,
and sealants or those recommended by
Yamaha, when servicing or repairing the
watercraft.

SAFETY WHILE WORKING
Under normal conditions, the lubricants men-
tioned in this manual should not harm or be
hazardous to your skin. However, you should
follow these precautions to minimize any risk
when working with lubricants.
1. Maintain good standards of personal and
industrial hygiene.
2. Change and wash clothing as soon as
possible if soiled with lubricants.
3. Avoid contact with skin. Do not, for exam-
ple, place a soiled rag in your pocket.
4. Wash hands and any other part of the
body thoroughly with soap and hot water
after contact with a lubricant or lubricant
soiled clothing has been made.
5. To protect your skin, apply a protective
cream to your hands before working on the
watercraft.
6. Keep a supply of clean, lint-free cloths for
wiping up spills, etc.
GOOD WORKING PRACTICES
1.The right tools
Use the recommended special service
tools to protect parts from damage. Use
the right tool in the right manner—do not
improvise.
2.Tightening torques
Follow the tightening torque specifications
provided throughout the manual. When
tightening nuts, bolts, and screws, tighten
the large sizes first, and tighten fasteners
starting in the center and moving outward.

3.Non-reusable parts
Always use new gaskets, seals, O-rings,
oil seals, cotter pins, circlips, etc., when
installing or assembling parts.
DISASSEMBLY AND ASSEMBLY
1. Use compressed air to remove dust and
dirt during disassembly.
2. Apply engine oil to the contact surfaces of
moving parts during assembly.
3. Install bearings with the manufacture iden-
tification mark in the direction indication in
the installation procedure. In addition, be
sure to lubricate the bearings liberally.
4. Apply a thin coat of water-resistant grease
to the lip and periphery of an oil seal
before installation.
5. Check that moving parts operate normally
after assembly.
