Risk of damage to machine components due to mixing dif-
ferent lubricants and operating fluids.
– Only use the same type of oils, lubricants and operating
fluids.
– Only use the oils, lubricants and operating fluids approved
by GROVE.
– Only mix the same type of or identical (same specification)
oils, lubricants and operating fluids from the same manu-

Information
The oils and lubricants approved by GROVE are found in the list of
operating fluids. The ambient temperature for operating the
machine must be between -20 °C and +50 °C (-4 °F and 122 °F). If
the on-site temperature exceeds these limits, consult your GROVE
Service Partner before starting up the machine.
The oil diagnosis is conducted by a qualified laboratory. Regular oil
diagnosis helps to avoid unnecessary costs. A series of tests will
determine the following:
Oil condition
n
Amount of abraded metal particles in the sample
n
Wear rate of components
n
Conducting an oil diagnosis is recommended for the following com-
ponents:
Hydraulic system
n
Drive engine

If there a risk of mineral oil-based oils and lubricants leaking and
harming the environment, biodegradable oils and lubricants must
be used.
Environmentally friendly lubricants are mandatory especially in
water conservation areas and nature reserves. Only synthetic,
ester-based biolubricants may be used.
See the list of operating fluids for more information.
