3. Note the following, and adjust as shown in the figure.
a. Obtain the point at the intersection of the measured values on the figure.
b. Read the coordinate (scale) of the intersection point.
c. Move the front/rear side adjusting bolts by each scale.  If the coordinate (scale) of the intersection point is positive, move the adjusting bolt to the vehicle inside.
 If the coordinate (scale) of the intersection point is negative, move the adjusting bolt to the vehicle out-
side.
d. Measure the camber and caster again. Check that the standard is within the proper range.
CAUTION:
 Always adjust the angle difference betw een left and right cambers within 33′.
 Always adjust the angle difference be tween left and right casters within 45′.
TOE-IN
Loosen the steering outer socket, and then adjus t the length using steering inner socket.
CAUTION:
 Always evenly adjust both toe-in alternately and adjust the difference between the left and right to
the standard.
 Always fix the steering inner socket when tightening the steering outer socket.

PRECAUTIONS
 To reinstall the rubber hose securely, check that hose insertionlength and orientation is correct. (If tube is equipped with hose
stopper, insert rubber hose into tube until it butts up against hose
stopper.)
HOSE CLAMPING
 If old rubber hose is re-used, install hose clamp in its original posi-tion (at the indentation where the old clamp was). If there is a trace
of tube bulging left on the old rubber hose, align rubber hose at
that position.
 Discard old clamps; replace with new ones.
 After installing plate clamps, apply force to them in the direction of the arrow, tightening rubber hose equally all around.
Engine OilsINFOID:0000000006280874
Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
 Avoid prolonged and repeated contact with oils, particularly used engine oils.
 Wear protective clothing, including impervious gloves where practicable.
 Do not put oily rags in pockets.
 Avoid contaminating clothes, pa rticularly underpants, with oil.
 Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-
larly.
 First aid treatment should be obtained immediately for open cuts and wounds.
 Use barrier creams, applying them before each work period, to help the removal of oil from the skin.
 Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepara-
tions containing lanolin replace the natural skin oils which have been removed.
 Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.
 If skin disorders develop, obtain medical advice without delay.
 Where practical, degrease components prior to handling.
 Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face
shields; in addition an eye wash facility should be provided.
