GI tMPORTANT INFORMATION
IMPORTANT INFORMATION
BASIC ASSUMPTIONS
This workshop manual assumes that you have certarn special tools that are necessary for the safe and
efficient performance of service operations on Mazda vehicles and that you know how to use them properly.
It also assumes that you are familiar with automobile systems and basic service and repair procedures.
YOU should not attempt to use this manual unless these assumpttons are correct and you understand the
consequences described below.
SAFETY RtSK
This manual contains certain notes, warnings, and other precautionary information that you should care-
fully read and follow to reduce the risk of personal injury to yourself or others and the risk of improper
service that may damage the vehicle or render it unsafe. If there IS no such information in regard to any
specific service method, this does not mean there is no possibility that personal safety or vehicle safety
wili be jeopardized by the use of incorrect methods or tools.
POSStBLE LOSS OF WARRANTY
The manufacturer’s warranty on Mazda vehicles and engines can be voided if improper service or repairs
are performed by persons other than those at an Authorked Mazda Dealer.
WARNtNG ON LUBRtCANTS AND GREASES
Avoid all prolonged and repeated contact with mineral oils, especially used oils. Used oils contaminated
during service (e+g., engine sump oils) are more irritating and more likely to cause serious effects, includ-
ing skin cancer, in the event of gross and prolonged skin contact.
Wash skin thoroughly after work involving 011.
Protective hand cleaners may be of value provided they can be removed from the skin with water Do
not use gasoline, paraffin, or other solvents to remove oil from the skrn.
Lubricants and greases may be slightly irritating to the eyes.
Repeated or protonged skin contact shoutd be avoided by wearing protective clothing if necessary. Par-
ticular care should be taken with used oils and greases containing lead. Do not allow work clothing .to
be contaminated with oil. Dry clean or launder such clothing at regular intervals.
