Position Equipment
1. Review bore plan and select drilling unit position and fluid unit position. See “Select Start and End
Points” on page 72.
2. Move equipment into selected positions.
Connect Fluid System
1. Connect fluid hose from mixing system to drilling fluid
pump. A 2.0” (50.8 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 143.
3. Press top of drilling unit throttle switch. Engine will increase to full throttle. If you do not want to use
autothrottle mode, return switch to center position.
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. See
page 210.
IMPORTANT: Ensure that mixture of drilling fluid matches drilling conditions. See “Drilling Fluid”
on page 138.
