SAFETY INSTRUCTIONS
DANGER: Failure to observe safety instructions and reasonable safety practices can
cause Property Damage, Serious Bodily Injury and/or Death. BE CAREFUL!! WATCH OUT
FOR BYSTANDERS!!
DANGER: NEVER run engine inside building or enclosed area. Exhaust gases contain carbon
monoxide, an odorless and deadly poison.
DANGER: NEVER drill holes where there is a possibilityof underground power cables or other
hazards. The exact location of underground services must be determined prior to drilling.
Inadvertent severing of telephone, fiber optic or CATV transmission cable, or damage to sewer
pipe is costly; RUPTURING OF GAS OR WATER LINES CAN CAUSE SERIOUS BODILY INJURY AND/
OR DEATH. COMING INTO CONTACT WITH BURIED POWER LINES CAN CAUSE SERIOUS BODILY
INJURY, SEVERE BURNS, AND/OR ELECTROCUTION. Call local utility companies or your local "One-
Call" number at least 48 hours before digging and have underground utilities marked.
WARNING: Never use hands to search for leaks. Instead, use a piece of cardboard or wood.
Escaping hydraulic fluid under pressure can have sufficient force to penetrate the skin, causing
serious injury. Before disconnecting lines, be sure to relieve pressure. Before applying pressure,
be sure connections are tight and fittings and hoses are not damaged.
WARNING: Augers are not to be used as anchoring devices.
CAUTION:
1. READ and understand this operator’s manual and the operator’s manual for the engine.
2. NEVER Operate drill without correctly installing torque tube.

MAINTENANCE AND LUBRICATION INSTRUCTIONS
NOTE: All engines and hydraulic reservoirs are shipped WITHOUT oil.
ENGINE: The engine is shipped without oil or gasoline. Refer to the manufacturers instructions for
proper procedures and recommended fluid.
HYDRAULIC FLUID AND FILTER: The hydraulic reservoir should be filled to the top of the sight gauge
with hydraulic oil before attempting to start the engine. Most premium grade, mineral based oil with anti-
wear (AW) and anti-foaming additives are suitable. The recommended fluid for normal temperature
operation is ISO VG 46 grade fluid. In colder climates use ISO VG 32 grade and in warmer climates use
ISO VG 68 grade fluid. The hydraulic oil and return line filter (Part # 30280) must be kept clean at all
times, and should be changed after the first 15 hours of operation. The filter and oil should be changed
every three months or after 100 hours of operation; whichever comes first.
NOTE: The hydraulic fluid and engine crankcase oil levels should be checked prior to each
days use.
IMPORTANT: All nuts, fasteners, and fittings must be kept tightened. If the engine or tank
mounting bolts are allowed to loosen, premature coupling and/or pump wear may result.
CAUTION: Escaping hydraulic fluid under pressure can have sufficient force to penetrate the
skin, causing serious injury. Before disconnecting hydraulic lines, be sure to relieve
pressure. Before applying pressure, be sure connections are tight and fittings, pipes and
hoses are not damaged. Use a piece of cardboard or wood, rather than hands, to search for
leaks. If injured by escaping fluid, see a doctor at once. Serious infection or reaction can
develop if proper medical treatment is not administered immediately.
KEEP all hydraulic lines away from moving parts.
HYDRAULIC OIL LEAKAGE
If any hydraulic oil leakage is encountered, shut down the power source and relieve the hydraulic
pressure by moving the throttle valve in both directions. Check and tighten the screw-on fittings on the
end of each hose. If the leakage persists, it may be necessary to replace the associated hose assembly.
If one of the Quick Disconnect fittings is the source of leakage, the quick disconnect coupling should
be replaced. If the throttle valve is leaking around the spool (shaft), you may replace the seal kit (Part
# 30275-2).
NOTE: To obtain maximum performance from power source, minimum hose size
recommended is 3/8".
HYDRAULIC HOSE ASSEMBLY REPLACEMENT
WARNING: For power source serial numbers from H-0001 through H-3252, do not exceed
the following maximum hose assembly lengths. Longer hose assemblies may allow the torque tube
to uncouple, causing serious personal injury.
If replacement hose assemblies are required, the maximum overall length of the pressure/return
hose assembly on the handle is 36". The maximum overall length of the pressure hose assembly on
the power source is 74 1/4" and the maximum overall length of the return hose assembly on the
power source is 68".
EXCESSIVE HEATING
Excessive heating is caused by placing too much down pressure on the auger which causes the oil
pressure to reach relief pressure. Oil flowing over the relief valve generates the heat.
DECAL LOCATION
The decals which are provided with your machine are shown at the rear of this manual. The decals shown
should be in the locations as described. If any of the decals are missing or illegible, order replacement
decal kit # 30181-D# and install before operating the machine.

TORQUE TUBE ASSEMBLY
WARNING: Properly install torque tube to prevent serious injury from kick-back torque while
drilling.
The torque tube consists of one end with a 1-1/2" square female fitting and a 1-1/4" square male
fitting on the other end. Attach the larger female end of the torque tube to the power source bracket
as shown in figure 1. Attach the other male end to the handle as shown in figure 2. Be sure to align the
snap button with the mating hole provided and check to be sure the snap buttons are securely snapped
into place.
WHEEL ASSEMBLY
Attach a wheel to each end of the rear axle using a 3/4" flat washer and securing with a 1/8" x 1"
cotter key. Attach the front wheel to the swivel bracket using one 3/4" x 5-1/2" cap screw, two spacers,
and one 3/4" lock nut.
OPERATION
BEFORE STARTING THE ENGINE,_Be sure that:
1.) Engine is properly prepared to Manufacturer’s specifications. Note: Engines with “Oil
Guard” protection must be filled with oil to full mark on dipstick or to point of
overflowing to allow the engine to start.
2.) Hydraulic Reservoir is filled to top of sight gauge.
3.) The torque tube is properly attached.
4.) There is no auger connected to the handle.
5.) The Quick Disconnect fittings are correctly coupled.
6.) The Torque Tube has engaged the Kill Switch at the Power Source.
TO START THE ENGINE: Set the choke lever to the “ON” position and pull the starter rope. The engine
should start after 2 or 3 pulls. Set the choke lever to the “OFF” position and allow the engine to warm-
up for 2 or 3 minutes.

AFTER THE ENGINE HAS WARMED UP, Insert the auger into the drive adaptor on the bottom of the
handle. Make sure the snap button and hole provided in the adaptor are aligned and the button snaps
securely into place. Hold the handle so your left index finger and thumb can operate the throttle (pull
with the index finger for forward rotation, push with the thumb for reverse). NOTE: ONLY use reverse
to free the auger if it becomes lodged in the ground. Grasp the right handle bar with your right hand.
Stand so the auger is straight up-and-down and is properly positioned to dig your hole (see figures 3
& 4). Note the safety instructions in this manual and on the machine’s decals.
FIGURE 3 FIGURE 4
IMPORTANT: Keep the back as vertical as possible by bending the legs, as required, during the
operating and lifting procedure.
ONE-MAN HANDLE
Always keep the leg pad against leg to maintain safe and stable control during operation.
TWO-MAN HANDLE
The operator controlling the throttle lever must alert the other operator prior to engaging the earth drill
to ensure readiness. Both operators must distribute even pressure on the auger, as required, to maintain
uniform drilling.
`
MAKE certain everyone is clear before operating the machine.
KEEP hands, feet and clothing away from moving parts while engine is running.
START THE AUGER TURNING By pulling the throttle lever in completely. Always allow the auger to turn
at full speed and let it cut its way into the soil.
IMPORTANT: When digging in soft soil, hold up slightly on auger. In hard pan, apply pressure, but not
enough to stall the auger or slow it down significantly. The auger works best when it turns at full speed.
IF THE AUGER STALLS repeatedly or slows down significantly; stop the auger by releasing throttle lever,
slightly lift up on auger, start auger by pulling throttle lever, and allow the auger to turn at full speed
while slowly lowering it to bottom of hole.
NEVER Remove auger from hole while auger is turning.
When the desired depth is reached, stop the auger by releasing the throttle lever. Then pull the auger
completely out of the hole.
IMPORTANT: Keep the back as vertical as possible by bending the legs, as required, during the operation
and lifting procedure.

AUGER EXTENSIONS
If greater hole depths are required, extensions
may be used with the auger. After the auger
has reached its maximum depth, stop the
auger and disconnect the drive adaptor from
the auger which remains in the hole. Connect
the extension to the auger as shown in figure
5. Connect the drive adaptor to the extension
and continue to dig the hole.
When the desired depth is reached, stop the auger and disconnect the drive adaptor from the
extension then remove the extension(s) and auger from the hole.
When working with cutting blade, point and auger flighting; be careful not to be cut by
sharp edges.

ATTACHMENTS:
Several attachments are available for your LITTLE BEAVER Earth Drill; including both west and dry
type horizontal boring kits and a drill chuck adaptor which allows you to use a wood bit. Refer to
the specific operating instructions supplied with the attachment. If these become lost or misplaced,
replacements may be obtained from the factory.
Page O-7
CUTTING BLADE
Check the cutting blade (Item A, Figure 6) on the auger fre-
quently. If it becomes dull, it may be reversed to use the other
cutting edge. If the outside of the blade wears even with the
auger flighting, replace the blade or rebuild it with a hard
surfacing rod. This is very important to reduce auger flighting
wear and damage. The point (Item B, Figure 6) should be re-
placed when it loses its cutting shape.
