If you notice that the working performance has decreased, the equipment vibrates or makes abnormal noise,
clean the attachment carefully and check the condition of the blades. See section 7.2 for more information
about the blades.
The rubber lip plate on front of the rotary hoe reduces the risk of thrown objects.
Replace faulty or worn rubber plate; do not use the rotary hoe if the rubber lip is
damaged or missing.
Ensure that the equipment is properly supported during all inspection, adjustment and
maintenance procedures. Ensure the support also when the rotary hoe has been
attached on the loader and note, that the loader boom may be moved even if the
loader engine is not running.
Check the condition of the hydraulic hoses and components when the engine has been turned off and the
pressure has been relieved. Repair all leaks immediately after detecting them; a small leak can quickly grow
into a big one. Do not use the equipment, if you have discovered a leak in the hydraulic system. Leaking
hydraulic fluid may penetrate skin and cause serious injuries. Hydraulic fluid is also harmful to the
environment.
Check hoses visually for cracks or abrasions. Monitor the wearing of the hoses and stop the use, if the
surface layer of the hose has worn off. If there are signs of leaking, to check the component, hold up a piece
of cardboard in the area where a leak is suspected. Finding any of these faults means that the hydraulic
hose or component must be replaced. Spare parts are available from your nearest AVANT retailer or service
point.
Never tighten a hydraulic fitting under pressure, since
the fitting may break and the released oil may cause
serious injuries. Do not use the equipment, if you
have discovered a fault in the hydraulic system.

Cleaning and lubricating the rotary hoe
Clean the rotary hoe as soon as possible after use, since this makes cleaning easier. Right after use, lift the
rotary hoe off the ground and rotate it on the air, starting slowly, to remove the largest lumps of soil from the
blades. Do not strike the hoe against the ground. You may use a pressure washer and mild detergent for
cleaning the equipment. Do not use strong solvents or spray directly at the hydraulic components or at the
labels on the attachment either. After washing lubricate the lubrication points.
The rotary hoe has two lubrication points, located at the ends of the
blade haft, to which a small amount of lubricant is added every 5-10
hours of use. The free end of the axle is directly accessible. To lubricate
the transmission end of the axle, the protective cover must be removed,
see figures in section 7.3. All lubrication nipples are standard R1/8”
nipples. Replace any damaged nipples.
Lubricant must be added approximately every 5 to 10 operating hours. Clean the end of the
nipple before greasing. Only add the grease amount of a couple of grease press pushes at
a time.
