PTO Shaft Length Adjustment
To adjust the length:
1 Hold the half-shafts next to each other in
the shortest working position and mark
them.
2 Shorten inner and outer guard tubes
equally.
3 Shorten inner and outer sliding profiles by
the same length as the guard tubes.
4 Round off all sharp edges and remove
burrs.
5 Grease sliding profiles before
reassembling.
CAUTION:
When attaching shaft to sprayer
and tractor, always ensure all guard covers
are in place. Operate the PTO slowly when
the PTO shaft is first attached to assess
installation. Care should be taken when
engaging the clutch so that sudden loading,
which can result in pump damage and gear
wear, is avoided. Ideally the pump should start
from zero pressure. It is essential to maintain
lubrication schedule while PTO shaft is in use.
PTO Shaft Lubrication
Proper grease is essential for the sprayer to
operate with maximum effectiveness and life-
expectancy.
CAUTION:
Never lubricate the PTO shaft while it is
running. It is important to keep the lubricant
and lubricant applicator clean. Wipe all
dirt from the fittings before use. Goldacres
recommends that multi-purpose grease should
be used for all lubrications.
The figures mentioned below refer to the
frequency (in hours) of lubrication for the
respective grease nipple locations.
• Pull shaft apart - apply grease to inside of
outer Telescopic profile
6. Check pump oil level prior to engaging
PTO.
7. Fill the tank with a quantity of water
sufficient to test spray unit for leaks.
8. Unfold the boom as per the boom folding
instructions in this manual
9. Make sure the pressure relief valve is
backed off prior to engaging PTO.
10. Visually check that all fittings are in place
and secure and taps are in working
positions.
11. Ensure that all taps are in the off position
and bypass back to tank is open. All boom
taps should be in the off position.
IMPORTANT:
Do not run diaphragm pumps
above 540 RPM.
12. To start the pump, engage the PTO at the
lowest revs possible and then gradually
increase revs until the pump reaches its
operating speed.
13. Set the pressure relief valve to the desired
spraying pressure. Once PTO has been
engaged and is running at 540RPM.
14. Gradually turn on individual boom
sections, until all sections are engaged.
15. Adjust pressure to suit desired spraying
rate.
16. Run unit at operating speed until contents
of tank are dispersed.
17. Take note of any water leaks, and tighten
fittings to rectify the problem immediately.
