Machine Preparation
Inspect the machine and perform any needed maintenance (for example, contaminated hydraulic fluid) before installing the
automated steering kit. This kit cannot perform as intended on a machine that is not maintained properly. Errors in
performance increase the risk of operator and bystander injury or death.
Failure to maintain clean hydraulic fluid and operational hydraulic components can cause loss of directional control resulting
in serious injury or death.
To avoid serious injury, wear hand and eye protection and use wood or cardboard when checking for leaks.
Turn off the machine and power off the automated steering controller when installing or performing maintenance.
Before attempting to install any of the components, park the machine on a clean level floor with adequate clearance to work all
around.
Before you perform any drilling, cutting or fastening, ensure that no other machine components, such as hydraulic hoses or
electrical wiring, will be damaged. Failure to follow this warning may cause physical injury and/or damage to the machine.
To prevent hydraulic system contamination, it is essential to thoroughly clean hydraulic system fittings and hose connections
prior to disconnecting or removing. Use a degreasing solvent spray cleaner such as a brake cleaner to prevent hydraulic system
contamination. Note that o-rings used on ORB and ORFF type fittings, referred to in the Kit Contents section, may be
damaged by degreasing solvent cleaners. If a fitting is to be cleaned internally, you should first remove and clean the o-ring
with a fiberless cloth.
