Risk of damage due to faulty suspension struts!
If the oil level is above the upper marking on the sight glass, the suspension
strut is faulty and must be replaced.
Notify
Manitowoc Crane Care or an authorised GROVE dealer.
S
Risk of damage to the suspension struts due to insufficient lubrication!
It is difficult to inject the oil. Do not fill oil through the inspection glass con-
nections. If you do this, the oil will not reach all the lubricating points.
