CHECKING AND ADJUSTING FRONT
WHEEL TOE-IN
This check must be done according to time intervals scheduled by the
operator, since any abnormality regarding the wheel toe-in is due to
impacts or vibrations, depending on type of surface which the machine
works.
Another reason for performing this check is to examine the front tires
for excessive wear.
The machine has been designed with a toe-in equal to 0 mm.
Every adjustment must restore this value and must be carried out on tie
rods (1) after loosening nuts (2) that lock them. (Use 27 and 19 mm
wrenches).
During this check and the relevant adjustment, it is advisable to also
check conditions of ball joints (3). If considerable slack is observed,
immediately replace them.
