D7x11 Series II Navigator Directional Drill Operation 50-35
After Each Bore
POWER VISES - CLEAN
Flush power vise assemblies with clean water to remove accumulated polymers or dirt. Refer to “Machine -
Wash,” page 50-36, for information on using the wash wand.
IMPORTANT: The service life of the power vise is dependent on proper operating techniques and cleanliness of
the mechanism.
Inspect vise jaws and grips and replace worn or damaged components before the next bore (refer to
“Maintenance - As Required” section in the Maintenance Manual).
DRILL RODS - CLEAN AND STORE
• Clean and lubricate drill rod threads to prevent rusting (refer to Specifications section, “Lubricants,” in the
Maintenance Manual).
• Protect drill rod from damage.
• Store drill rods in the rod box on machine.
• Close and secure rod box cover to prevent drill rods from falling out during transport.
WARNING: High pressure water can penetrate skin. Serious injury possible. Fluid
injected under the skin must be removed immediately by a surgeon familiar with this
type of injury.
Keep nozzles away from body.
