2 CHAPTER ONE
Well-equipped mechanics may be able to substitute simi-
lar tools or fabricate a suitable replacement. However, in
some cases, the specialized equipment or expertise
required may make it impractical for the home mechanic
to attempt the procedure. When necessary, such opera-
tions arc identified in the text with the recommendation to
have a dealership or specialist perform the task. It may be
less expensive to have a professional perform these jobs,
especially when considering the cost of the equipment.
WARNINGS. CAUTIONS AND NOTES
The terms WARNING, CAUTION and NOTE have
specific meanings in this manual.
A WARNING emphasizes areas where injury or even
death could result from negligence. Mechanical damage
may also occur. WARNINGS are
to be taken seriously.
A CAUTION emphasizes areas where equipment dam-
age could result. Disregarding a CAUTION could cause
permanent mechanical damage, though injury is unlikely.
ANOTE provides additional information to make a step
or procedure easier or clearer. Disregarding a NOTE
could cause inconvenience, but would not cause equip-
ment damage or injury.
SAFETY
Professional mechanics can work for years and never
sustain a serious injury or mishap. Follow these guide-
lines and practice common sense to safely service the ve-
hicle.
1. Do not operate the vehicle in an enclosed area. The ex-
haust gasses contain carbon monoxide, an odorless, color-
less, and tasteless poisonous gas. Carbon monoxide levels
build quickly in small enclosed areas and can cause un-
consciousness and death in a short time. Make sure the
work area is properly ventilated or operate the vehicle out-
side.
2. Never use gasoline or any extremely flammable liquid
to clean parts. Refer to Cleaning Parts and Handling Gas-
oline Safely
in this chapter.
3.
Never
smoke or use a torch in the vicinity of flamma-
ble liquids, such as gasoline or cleaning solvent.
4. If welding or brazing on the vehicle, remove the fuel
tank, carburetor and shocks to a safe distance at least 50 ft.
(1 5 m) away.
5.
Use the correct type and size of tools to avoid damag-
ing fasteners.
6. Keep tools clean and in good condition. Replace or re-
pair worn or damaged equipment.
7. When loosening a tight fastener, be guided by what
would happen if the tool slips.
8.
When replacing fasteners, make sure the new fasteners
are the same size and strength as the original ones.
9. Keep the work area clean and organized.
10.
Wear eye protection anytime the safety of your eyes is
in question. This includes procedures involving drilling,
grinding, hammering, compressed air and chemicals.
11. Wear the correct clothing for the job. Tie up or cover
long hair so it cannot get caught in moving equipment.
12. Do not carry sharp tools in clothing pockets.
13.
Always have an approved fire extinguisher available.
Make sure it is rated for gasoline (Class B) and electrical
(Class
C) fires.
14. Do not use compressed air to clean clothes, the vehi-
cle or the work area. Debris may be blown into eyes or
skin. Never direct compressed air at yourself or someone
else. Do not allow children to use or play with any com-
pressed air equipment.
15. When using compressed air to dry rotating parts, hold
the part so it cannot rotate. Do not allow the force of the air
to spin the part. The air jet is capable of rotating parts at
extreme speed. The part may damage or disintegrate,
causing serious injury.
16.
Do not inhale the dust created by brake pad and clutch
wear. These particles may contain asbestos. In addition,
some types of insulating materials and gaskets may con-
tain asbestos. Inhaling asbestos particles is hazardous to
people's health.
17. Never work on the vehicle while someone is working
under it.
18.
When placing the vehicle on a stand, make sure it is
secure before walking away.
Handling Gasoline Safely
Gasoline is a volatile flammable liquid and is one of the
most dangerous items in the shop.
