Position Equipment
Position Equipment
1. Review bore plan and select drilling unit position and fluid unit position. See “Select Start and End
Points” on page 87.
2. Move equipment into selected positions.
3. Drive anchors. (See “Anchor System” on page 149.)
4. Connect and test electric strike system. (See “Electric Strike System” on page 152.)
Connect Fluid System
1. Connect fluid hose from mixing system to drilling fluid
pump. A 2.0” (50.8 mm) or larger, non-collable hose is
required.
2. Install y-strainer between mixing unit and drilling fluid
pump. Position strainer so that drilling fluid flows in
the direction of the arrow. In most cases, positioning
strainer at outlet of mixing unit gives best results.
Electric shock will cause death or serious injury. Stay
away.

To help avoid injury: Do not connect drilling unit to a public or private (business or home) water supply.
If an electrical strike occurs while drilling unit is connected to a fluid system, the fluid system will also
become electrified.
IMPORTANT: Clean y-strainer regularly. See
page 213.
