ADJUSTMENT
1.
Raise tilt support lever (Figure 1, Item 6) until deck is fully raised.
2.
While continuing to hold tilt support lever (Figure 1, Item 6) in raised position, check psi reading on pressure
gage (Figure 1, Item 1). Reading should be 900-1,100 psi (6,205.3-7,584.2 kPa). If reading is higher than
1,100 psi (7,584.2 kPa) or lower than 900 psi (6,205.3 kPa), adjust pressure by adjusting hydraulic control
valve (Figure 1, Item 5) as follows:
a.
Remove small barrel nut (Figure 1, Item 3) on hydraulic control valve (Figure 1, Item 5) and loosen
jamnut (Figure 1, Item 4).
WARNING
DO NOT exceed 1,100 psi (7,584.2 kPa). Failure to comply may result in death or
injury to personnel. Seek medical attention in the event of an injury.
b.
Rotate Allen stud (Figure 1, Item 2) located inside barrel nut (Figure 1, Item 3) on hydraulic control
valve (Figure 1, Item 5) clockwise to raise pressure setting, or counterclockwise to lower
pressure setting.
c.
Retighten jamnut (Figure 1, Item 4) and reinstall barrel nut (Figure 1, Item 3).
d.
Repeat Steps 1 and 2. If pressure reading is still not correct, verify pressure on towing vehicle
supply system.
