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 (point A), 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 discon-
necting 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.
