Keep the DTH hammer in good working
condition
Keep your DTH hammer in proper working condition.
Unauthorized modifications to the DTH hammer may impair the
function and/or safety and effect the DTH hammer life.
Make sure all safety devices, including shields are installed and

Wear protective clothing
Wear APPROVED safety equipment (safety shoes, safety glasses,
hearing protection, hard hat, gloves, respirator, etc.) when
operating or maintaining the DTH hammer .
Wear close fitting clothing and confine long hair.
Operating equipment requires the full attention of the operator.

hammer.
Check for underground utility lines
Before starting work, remember that contact with buried utilities
may cause serious injury or death. Electric line contact may
cause electric shock or electrocution. Gas line contact may
rupture pipe causing explosion or fire. Fiber optic cables can
blind you if you look into the laser light in them. Water line
rupture may cause a flood and possible ground collapse. Before
drilling, check with qualified sources to properly locate all buried
utilities in and around drill path. Select a drill path that will not
intersect buried utilities. Never launch a drill bit on a path
toward electric, gas, or water lines until their location is known.
If there is any doubt as to the location of the underground
placement, have the utility company shut it off before starting
any underground work and excavate to confirm its exact
location.
