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 in question 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.
7.1.
Cleaning the equipment
You may use a pressure washer and a mild detergent to clean the backhoe. Do not use strong solvents or
spray directly at the hydraulic components or at the labels on the attachment either. Lubricate the lubrication
points on the attachment after washing.
Do not let water to stay in the bucket. For longer storage periods touch up the paint where needed, grease
the lubrication points and oil the visible parts of hydraulic cylinder shafts to prevent rust damage. Do not
store the attachment directly against the ground; place it on blocks of wood or on a pallet, for example.
7.2.
Lubricating
The lubricating of the backhoe consists of lubricating the 14 lubricating points of the backhoe and the slewing
chain. A small amount of lubricant should be added every 5-10 hours of use. The locations of the lubrication
points are shown in the figures below. All lubrication nipples are standard R1/8” nipples, replace any
damaged nipples.
Lubricate the also the slewing chain with suitable oil when the lubricating points are greased. Lubricate the
chain also when storing the backhoe for longer storage periods to prevent rust damage.
