USE AND MAINTENANCE
7) IMPORTANT !!
With the double-acting lift cylinders the handle 1 must be removed from the machine
because, if it remains positioned on the support’s holes (except the the starting one A), there
would be serious damages to the machine. It can also be positioned on the initial hole A but
we don’t suggest it to avoid someone inadvertenly or mistakenly move the handle 1 on the
holes subsequent to the first.
) DANGER
For this operation please refer to
the general manual of the
machine. Connect in a proper
way the new hose A to an
hydraulic double-acting hitch B.
