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 life of your scraper can be severely shortened by poor maintenance. Follow
consistent maintenance practices and use good quality grease and hydraulic oil (compatible with the
power unit’s hydraulic system) to insure the longest, most productive use from your equipment.
Before starting the job, make sure Diggers Hot Line has been contacted and all underground utilities
have been properly located (electric, phone and pipelines). Have a clear understanding of all local,
OSHA and MSHA rules that apply to the job. Beware of your environment and keep others a safe
distance from the machine while familiarizing yourself with the machine’s controls. 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 disconnecting any oil line to keep all dirt out of the oil
as dirt is a major factor in the failure of hydraulic components. Each time the scraper is holed to a
power unit, the sequencing valve needs to be checked for proper timing. This will insure optimum
performance from the scraper.
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. The operation of the scraper will vary depending upon soil type, moisture
content, power-unit and jobsite. Results will vary.
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.
