Operation Overview - 28 FM13V/FM13X Operator’s Manual
Transferring Fluid
Transferring Fluid
1. Connect mixing pump hose to drilling unit.
2. Open discharge valve of mixing pump, adjust engine throttle to full to purge all air from the line when
starting drilling fluid pump on drilling unit. After flow is stable, adjust throttle to give desired flow rate to
drilling unit (approximately half throttle).
Operating in Cold Weather
For successful operation in cold weather, follow these procedures.
• Use pump to keep drilling fluid circulating at all times, even during transport to and from the jobsite.
• If possible, use all drilling fluid in tank before transporting unit.
• For cold weather storage, drain tank and ensure all fluid system valves are open. Also open drain
valve on pump.
Leaving Jobsite
1. Rinse unit and tools (page 44).
2. Disconnect hoses (page 44).
Electric shock. Contacting electric lines will cause death or serious injury.
Know location of lines and stay away.
To help avoid injury: Remember that if electrical strike occurs while fluid hose is connected to drilling
unit, fluid system will also become electrified.
NOTICE: To prevent damage to the drilling fluid pump, make sure y-strainer is used in-line
between mixing unit and drilling unit.Add polymers at a very slow rate.
IMPORTANT:
• To reduce agitation in tank when using polymer-based drilling fluids, partially close the tank jet
valve.
• Overmixing of polymer-based drilling fluids can reduce fluid viscosity.
• Close venturi valve when dry chemical hopper is not in use.
