Position Equipment
1. Review bore plan and select drilling unit position and fluid unit position. See “Select Start and End
Points” on page 67.
2. Move equipment into selected positions.
Connect Fluid System
1. Connect fluid hose from mixing system to drilling
fluid pump. A 1.5” (38 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 127.
3. Press top of drilling unit throttle switch until engine is at 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.
NOTICE: 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:
• Clean y-strainer regularly. See page 172.
• Prime the remote drilling fluid pump after
switching to a new tank. See page 94.
IMPORTANT: Ensure that mixture of drilling fluid matches drilling conditions. See “Drilling Fluid”
on page 122.
