1.
Check hydraulic fluid level in tractor reservoir and fill to
proper level. Add fluid to system as needed.
2. With drill unfolded and fold cylinders completely ex-
tended, disconnect rod-end pins and swing cylinders
so they will not contact anything when extended.
3. Loosen rod-end-hose fitting at elbow on left fold cylin-
der (1). See Figure 1-6.
NOTE: Do not loosen an O-ring fitting. Bleeding air from
an O-ring fitting will damage the seal.
4. Slowly supply oil to rod end of fold cylinders until oil
appears at loosened hose fitting. Tighten fitting and
completely retract fold cylinders.
5. With cylinders completely retracted, loosen base-end-
hose fitting at elbow on left fold cylinder (2). See Fig-
ure 1-6.
6. Slowly supply oil to base end of fold cylinders until oil
appears at loosened hose fitting. Tighten fitting and
cycle fold cylinders in and out several times.
