12. If a hydraulic leak develops, correct it immedi-
ately. Escaping hydraulic oil can have ex-
tremely high pressure. A stream of high
pressure oil may easily penetrate the skin as
with modern needle-less vaccination equip-
ment - but with the exception that hydraulic
fluid may cause blood poisoning. It is impera-
tive that the connections are tight and that all
lines and pipes are in good condition. If an in-
jury is caused by the escaping hydraulic fluid,
see doctor at once!
13. Use a piece of cardboard or wood to detect
leaks of hydraulic oil under pressure.
14. Be sure to relieve all hydraulic pressure before
disconnecting any lines or pipes between the
implement and the tractor hydraulic system.
Keep all guards and shields in place.
Assembly Instructions
Refer to Figure 1
1. Mount coulter blade (5) to hub using carriage
bolt (8) and fasteners (6) & (7). Tighten nuts.
2. Lock set screw (3) in swivel collar (4) onto the
vertical shaft (1), (purchased separately) with
roll pin below swivel mounting casting (2).
3. Mount clamp brackets (purchased separate-
ly) with coulter vertical shaft to tool bar. Ad-
just vertically and align with unit as desired,
so coulter assembly is running true with unit.
Spring Adjustments
No spring adjustment is necessary on this unit.
Initial operating force to move coulter upwards is
540 pounds. The preload has proved to be more
than adequate for most No-Till conditions.
Any attempt to make coulter force greater than factory
setting, may contribute to premature failure of parts
and warranty shall be null and void.
