Replacements and Repairs
Safety is important in connection with all repair work on the AXR-H. The following
safety precautions must be observed:
When performing repair or maintenance work on the AXR-H, the implement must
first be resting properly and securely on the ground.
It is extremely dangerous to work or walk under the AXR-H when it is has been
raised by the lift/lifted on the wheel frame unless the implement is securely sup-
ported or held into position. The engine of the tractor must be stopped and the
brakes must be locked.
After making repairs to the hydraulic system, always bleed air out of the system
before operating the harrow again to avoid any possible personal injury or mechan-
ical breakdown or damage.
Never allow bystanders within the operating radius of the AXR-H while the hydraulic
units are in operation. This area is considered to be fatally dangerous.
When dismounting/mounting components, always pay careful attention to the
weight of the part you are about to handle. It is important to support or secure the
part so that it cannot fall.
Replacing Disc Bearings
Before changing the bearings, the AXR-H must be hitched to a tractor and the im-
plement must be unfolded and resting securely on the ground. Lower the transport
wheels on the AXR-H so that the wheels just barely carry the weight of the AXR-H,
but the discs are still resting on the ground.
