Position Equipment
Position Equipment
1. Review bore plan and select drilling unit position and fluid unit position.
2. Move equipment into selected positions.
Connect Fluid System
1. Connect fluid hose from mixing system to
drilling fluid pump. A 3” (76 mm) or larger,
non-collapsible 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.
Start System
1. Start drilling unit and remote fluid unit. Allow both engines to warm up.
2. Enable tracker control mode if desired. See “Tracker Control” on page 133.
3. Press top of drilling unit throttle switch until engine is at full throttle.
4. Press and hold quick fill fluid pump switch until pipe fills and fluid pressure begins to rise.
Electric shock. Contacting electric lines will cause death or serious injury.
Know location of lines and 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.
IMPORTANT: Ensure that mixture of drilling fluid matches drilling conditions.
