Equipment Modification

HT220 Operator’s Manual Overview - 3 Intended Use Intended Use The HT220 is a large track trencher designed dig trenches up to 24” (609 mm) wide and 96” (2.44 m) deep. The trencher’s hard metal teeth remove very hard, rocky ground and thinly crush it. The result is an even, rectangular-shaped trench ready for laying pipes or cables. The unit is designed for operation in temperatures typically experienced in earth moving and construction work environments. Provisions may be required to operate in extreme temperatures. Contact your Ditch Witch dealer. Use in any other way is considered contrary to the intended use. The HT220 should be used with genuine Ditch Witch chain, teeth, and sprockets.

It should be operated, serviced, and repaired only by persons familiar with its particular characteristics and acquainted with the relevant safety procedures. Equipment Modification This equipment was designed and built in accordance with applicable standards and regulations. Modification of equipment could mean that it will no longer meet regulations and may not function properly or in accordance with the operating instructions. Modification of equipment should only be made by competent personnel possessing knowledge of applicable standards, regulations, equipment design functionality/requirements and any required specialized testing.
