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
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.
