I-900
OPERATORS AND MAINTENANCE INSTRUCTIONS
This scraper is a durable piece of equipment and with proper care will yield many years of trouble free
operation. The scraper requires a power source with TWO 4 way (double acting) hydraulic control valves.
The scraper should be greased at all points where grease fittings are provided. Connect hydraulic
hoses to the tractor and retract lift cylinders to REMOVE TRANSPORT LOCK PINS, then extend and
retract all cylinders several times to force out any air from the hydraulic cylinders and lines. Check the oil
levels in the tractor hydraulic system and add to maintain the proper level. Care should be used when
adding oil or when disconnecting any oil line to keep all dirt out of the oil as dirt is a major factor in the
failure of hydraulic components.
When the scraper is placed into operation, the operator will have to “feel out” the amount of depth of
cut to obtain maximum loading efficiency. This is usually accomplished by taking a lesser and more
uniform cut; however, some soil conditions such as loose sand may require a “pumping action” obtained
by taking successive deep cuts and lifting out of cut as the tractor begins to lose power or traction.
1.
After 10 hours work, all bolts should be checked and tightened if necessary.
2.
Every 10 hours all grease fittings should be lubricated.
3.
After 50 hours work, all bolts should be rechecked and tightened if necessary. Check wheel
bearings and adjust if necessary.
4.
After 300 hours work, clean and repack wheel bearings and replace, if necessary, cutting edges,
worn pins, etc.
