Conduct a Bore - 117
Position Equipment
Position Equipment
1. Review bore plan and select drilling unit position and fluid unit position. See “Inspect Site” on page 82.
2. Move equipment into selected positions.
3. Use setup controls (29) to adjust drill frame as required by bore plan. See “Plan Bore Path” on
page 87.
4. Drive anchors. See “Anchor Drilling Unit” on page 139.
5. Unlatch shuttle guard and lower into position.
Connect Fluid System
1. Connect fluid hose from mixing system to drilling
fluid pump. A 3” (76 mm) supply hose no more than
50’ (15 m) is required.
To prevent pump
cavitation , hose must provide 30 psi (2 bar) of
continuous pressure at the drilling fluid pump inlet.
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.
274-049
To help avoid injury: If an electrical strike occurs while drilling unit is connected to a fluid system, the
fluid system will also become electrified. Do not connect drilling unit to a public or private (business or
home) water supply.
IMPORTANT: Pump cavitation causes damage
to pump and other machine components and
reduces pump output.
IMPORTANT: Clean y-strainer regularly. See
page 206.
