13. IMPORTANT: BEFORE ACTIVATING HYDRAULIC CYLINDERS, DISCONNECT EXISTING
PINS USED FOR TINE ANGLE ADJUSTMENT.

14. Install hydraulic tips.
15. Initial Start-Up for HTA hydraulic cylinders:
Hydraulic cylinders for the HTA option should not be charged with oil until machine is lowered into
field position. There must be pressure on harrow tines for cylinders to extend and retract properly.
A. Lower machine slowly into field position. Insure that hydraulic hoses do not get pinched or
stretched.
B. Slowly extend Tine Angle hydraulic cylinders. Check for interference and leaks, correct if they
occur.
The Hydraulic Tine Angle option is operated with a master – slave hydraulic system. Fully extend
hydraulic cylinders and hold hydraulic lever for 30 seconds to insure that all air is purged from sys-
tem. Each cylinder has rephasing slots located on rod end of barrel. When cylinder is fully extend-
ed, these slots allow oil to flow through.
