It is dangerous if the work equipment moves by mistake when the blade is adjusted.
Set the work equipment in a stable condition, then stop the engine. Securely set the work equipment
lock lever and parking brake lever to the respective LOCK positions.
NOTICE
If the wear of the center blade boss is left as it is, it becomes difficult to work stably and the machine
may be damaged.
If shims (1) and (2) in bosses (3) of the center blade are worn, folding or unfolding of the blade becomes diffi-
cult. Replace and adjust shims (1) and (2) in the bosses at both ends according to the following procedure.

Raise the blade and set it in parallel with the machine.

If shims (1) and (2) at the bosses (4 places) of the center
blade are worn, remove them.
4.
Measure clearances (A) and (B) in the bosses of the fold-
ing blade.
5.
Insert new shims (1) and (2) so that clearances (A) and (B)
are 0 to 0.5 mm {0 to 0.020 in} , then install pins (4).
