OPERATORS AND MAINTENANCE INSTRUCTIONS
The 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 ttings 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 efciency. 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 ttings 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..
5. Tighten all wheel bolts after rst two hours use. Check daily for two weeks. Keep
torqued to 450 ft. lbs..
6. Maintain tire pressure at 35 to 40 psi on a rear unit, 40-50 on a front unit.
