Pliers . A few of the many types of
pliers are shown in
Fig .
10 .
Most are used for holding irregular objects,
bending, or crimp-
ing . Some have special
applications .
A needlenose plier is used for gripping small and poorly ac-
cessible objects, and is useful for wiring and other electrical
work . A locking plier such as the Vise-Grip ® is useful because
of its tight grip .
Snap-ring and circlip pliers with special tipped jacas are
used
lo remove and install snap-rings or circlips . A Channel-lock® or
water pump
plier has adjustable jacas that can be quickly
changed to match the size of the object being held to give great-
erleverage .
An adjustable wrench can be a useful addition to a small tool
kit . See Fig . 11 . It can substitute in a pinch, if two wrenches of
the same size are needed lo remove a nut and bolt . Use extra
care with
adjustable wrenches, as they tend to loosen, slip, and
damage fasteners .

Compared to a wrench of the correct size, an adjustable
wrench is always second best . They should only be used when
the correct size wrench is not available . Choose one of average
size range, about 6 to 8 inches in length .
Jack Stands
Strong jack stands are extremely important for any work that
is done under the car . Use only jack stands that are designed
for the purpose . Blocks of wood, concrete, bricks, etc . are
not
safe or suitable substitutes .
WARNING -
A jack should
be used only to raise the vehicle and
shouldnot be used to support the car for a long pe-
riod . Always use jack stands to support a raised ve-
hicle .
Jack stands are
available 1n severa¡ styles . A typical jack
stand is shown in
Fig
. 12 . The best ones are made of heavy ma-
terial for strength, have a wide base for stability, and
are
equipped lo positively lock in their raised
positions . Get the best
ones available .
