Hydraulic Earth Drill Service
Q. What type of hydraulic oil should I put in the reservoir of my Little Beaver Hydraulic Earth Drill?
A. Most premium grade, mineral based oils with anti-wear (AW) and anti-foaming additives are suitable. ISO VG 46 grade fluids are recommended for operation in normal temperature environments. Use ISO VG 32 grade in colder climates or ISO VG 68 in warmer climates.
Q. How much hydraulic oil does it take to fill the reservoir of my Hydraulic Earth Drill?
A. The Little Beaver hydraulic earth drill holds 5 gallons of oil. The Little Beaver towable hydraulic earth drill holds 6 gallons of oil. The PS-18 power source holds approximately 2.75 gallons.
Q. What types of daily maintenance do I need to perform on my Hydraulic Earth Drill?
A. Both the engine oil and the hydraulic oil levels should be checked daily. You should also visually inspect the Little Beaver to verify that no parts or fasteners are loose, damaged, or missing, and check the hydraulic hoses for wear and abrasion.
Q. My Hydraulic Earth Drill does not seem to have the power that it used to have. What is wrong?
A. Have you recently changed your hydraulic oil? Some retail or automotive stores sell multipurpose oils designed for tractors that are labeled as hydraulic oils, but are not suitable for use in your power source. Make sure that you always use the recommended grade when replacing your hydraulic oil. Follow the schedule in your operation and maintenance manual regarding oil and filter changes
Q. When using my Hydraulic Earth Drill, the auger turns fine in one direction, but does not turn or turns very slowly in the other direction. When I touch the auger to the ground it stops. What’s wrong?
A. Most likely your valve control linkage is bent. This is the small rod that connects the control to the valve spool. Straighten it out, and then make sure that the flat part of the lever (the part you pull or push with your fingers) does not touch the handlebar at any time.
Q. I’m trying to start the engine on my Hydraulic Earth Drill, but it is hard to pull the starter rope. How do I correct this?
A. Make sure that the quick disconnect couplings are fully engaged. When connecting the handle to the power source, connect the return side first (the long hose that comes from the return line filter), then connect the pressure side.
Q. I use my Hydraulic Earth Drill for sign erection. Taking it out of the truck bed and back in again is not easy. Is there anything I can do about this?
A. Little Beaver’s Telescoping Torque Tube Kit consists of a 2-man hydraulic handle, bumper mounted swivel bracket, and a telescoping torque tube. With this Kit, the hydraulic power source can remain in the bed of the truck while the swivel bracket allows 180 degree maneuverability. The torque tube mounts to the swivel bracket and extends from 6 to 11 feet. It may be used with any of the Little Beaver hydraulic power sources, truck auxiliary hydraulic power, or other brands of power sources which meet Little Beaver specifications (6-8 GPM flow, 2000 -2500 Maximum PSI).
Q. After traveling to the job site with my Little Beaver Towable Earth Drill, I can’t pull the recoil rope or the engine is flooded. What’s wrong?
A. You probably did not close the fuel shut-off valve during transit. As a result, fuel flooded the cylinder. Close the fuel shut-off valve and remove the spark plug. While standing off to the side of the cylinder, slowly pull the recoil rope a few times to purge gasoline from the cylinder. Be sure to clean up any spilt fuel. Then, clean and replace the spark plug, open the fuel shut-off valve and try starting the engine again.
Q. How fast can I tow my Towable Earth Drill?
A. 25mph is the maximum towing speed allowed when the SMV sign is displayed.
Q. What size trailer ball do I need to tow my Towable Earth Drill?
A. The towable earth drill requires a standard 2” trailer ball.
