The above table includes 25 bar back pressure on the
tractor hydraulic system. See also section on Technical
specifications. With load sensing or constant pressure
systems, back pressure may be higher. If in doubt,
contact your tractor dealer.
After initial operation of the boom and blower, check the
hydraulic oil level of the tractor and top up if necessary.

The trapeze
suspension
needs to be
correctly
adjusted and
lubricated for satisfactory
operation. Its function
is to protect the
boom from vibra-
tion and shock
thereby prolonging
boom life. It also
helps to keep
the boom a
uniform height from the target. See also sections Lubri-
cation and Re-adjustment of the boom.
At delivery the boom is locked in pos. 2 which is used
when driving on horizontal grounds. When driving on
slopes the boom can be slanted in pos. 1 or 3 in order to
keep the trapeze effect. Hydraulic slanting can be
supplied as optional extra.
If Hydraulic Slanting Control is fitted, another double
acting outlet is required. Note that whilst activating this
function, fan output may be reduced.
