OPERATION AND MAINTENANCE
2. The hydraulic system is not filled with oil and should
be purged of air before transporting and field
operations. Carefully hitch the VT Plus to the tractor
and connect the hydraulic lift hoses. Check to make
sure the tractor hydraulic reservoir is full of the
manufacturer's recommended oil. Slowly raise the
machine, and continue to hold the hydraulic lever
until all lift cylinders are fully extended. Lower and
raise the unit to verify that all cylinders are working
simultaneously throughout the stroke. If the cylinders
are not working evenly or together, fully extend the lift
cylinders and continue to hold the lever to purge any
remaining air. Do not loosen any hoses or fittings.
Recheck tractor reservoir to make sure it is within
operating limits. With all cylinders fully extended,
install the 1-3/8 X 10 transport lockouts (See
Figure 4-3.) Storage location for lockouts (See
Figure 4-4.)
3. Always fully extend the cylinders and hold the lever to
ensure the cylinders are rephased before starting
any field operation. This will keep all cylinders in time
and frame sections level when operating.
