Boom adjustment
The FTZ Force boom is built to handle our tough Australian conditions and will deliver years of reliable service
when correctly maintained and adjusted. Please note the following points prior to adjustments:
1. Ensure the boom is well lubricated (see maintenance / lubrication schedule for details).
2. Connect the sprayer to the tractor and place the rig on a solid level surface. Unfold the boom completely.
3. Shut down the tractor, place the gearbox in a low gear, engage the handbrake and remove the ignition key.
4. Place wheel chocks in front and behind wheels.
5. If adjusting hydraulic cylinders, depressurise the hydraulics fi rst.
6. Always think the job through fi rst and asses any potential risk.
7. Always use lifting and safety equipment of a suitable load bearing capacity.
Warning: Ensure the area around the boom is clear of persons when making adjustments and never
disconnect the sprayer from the tractor with the boom unfolded unless correctly supported.
Boom centre and inner section alignment
Ideally the tip of the boom should point slightly forward when
unfolded for spraying. This slight forward angle is achieved by the
alignment / travel stop screw located at the fold between the inner
section and the boom centre.
If necessary adjust the inner section as follows:
1. Depressurize the fold cylinders.
2. Loosen the lock nut (A).
3. Adjust the travel stop screw (B) until the correct setting is
achieved.
4. Tension the lock nut, double check your adjustment and repeat
the process for the other side.
Section alignment and over centre locking mechanisms
The FTZ intermediate and outer section folds incorporate two
critical adjustments which must be maintained regularly.
1. Horizontal alignment between the two wing sections (B).
2. An 'over centre' locking mechanism (A) which, when adjusted
correctly, locks the wing sections in place while spraying.
Section alignment
1. With the sprayer attached to the tractor, unfold the boom to
the operating position, switch off the tractor. Prepare the rig
for service as previously described, and depressurise the fold
cylinders.
2. Dis-connect the outer end of the fold cylinder (C) and loosen
the lock nuts (D).
3. Adjust the travel stop screws (B) until the inner and outer wing
sections are perfectly aligned with one another.
4. Re-tension the lock nuts (D).
5. Proceed to the 'over centre' locking mechanism adjustment.
