Operation and Maintenance
Thank you for choosing Ashland for your scraper needs. Your Ashland scraper is a durable
piece of equipment, and with proper care it will yield many years of trouble free operation.
However, the life of your scraper can be severely shortened by poor maintenance. You
must follow consistent maintenance practices and use good quality grease and hydraulic
oil (compatible with your power unit’s hydraulic system) to ensure the longest, most
productive use from your scraper.
Before starting a job, make sure the Diggers Hot Line has been contacted and all
underground utilities have been properly located (i.e. electric, phone, and pipelines). Have
a clear understanding of all local, OSHA, and MSHA rules that apply to your job. Beware
of your environment and keep others a safe distance from the machine while familiarizing
yourself with its controls. Your scraper requires a power source with TWO 4-way (double
acting) hydraulic control valves.
Your 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. Next, 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 as needed to maintain proper levels. Care should be used when adding oil or when
disconnecting any oil line to keep dirt out of the oil. Dirt is a major factor in the failure of
hydraulic components.
When your scraper is placed into operation, the operator will have to “feel out” the depth
of cut needed 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
the cut as the tractor begins to lose power or traction.
• After 10 hours of work, all bolts should be checked and tightened if necessary.
• After every 10 hours of work, all grease fittings should be lubricated.
• After 50 hours of work, all bolts should be rechecked and tightened if necessary.
Check wheel bearings and adjust if necessary.
• After 300 hours of work, clean and repack wheel bearings. If necessary, replace
cutting edges, worn pins, etc.
