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.
