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. Even so, do not fill oil through the sight glass
connections. If you do this, the oil will not reach all the lubricating points.
