DELINEATION OF RESPONSIBILITY
SPECIFIC DECLARATION
A grader is an engineering vehicle with a blade used to finish soil and create a flat surface. Graders
are commonly used in the construction and maintenance of gravel road and sub grade. Graders
are also used to strip topsoil or greensward, produce ditches, finish side slope. Graders can mix
up, backfill, bulldoze and pave materials. If equipped with a front dozer blade, it can pave, stack
and backfill loose materials. If equipped with a rear scarifier, it can loose hard and dense soil. Any
other use or any operation beyond the specified working range is not authorized use. Sany ex-
pressly bears no liability for any consequence due to any unauthorized use.
