(Click on a question to get the answer.)
1] Why does my F-Series gearbox leak oil?
You should not put oil in your F-Series gearbox (including the F8). The F8 is shipped from our factory with 3 lbs. of Shell Alvania EP2 Grease (old name - Texaco MultiFax-EP2). Always use 3 lbs. of a good quality gun grease.

be used in my J20/80, G20/40, 8300 Series, and 8800 Series gearbox?
| Remove the fill plug at the top of the gearbox, and fill the gearbox with two quarts of multigear lubricant EP SAE 140 before operating the gearbox. Tip the gearbox 45 degrees (avoid pinch points as gearbox pivots), and check the level at the plug (see image). DO NOT OVERFILL! Replace the plug before operating the digger. |  |

13] How can I dig a deeper hole than my auger will allow?
Dig deeper holes by adding auger extensions to your auger. All Danuser
Auger Extensions come with an Auger
Extension Guard. If you
have an auger extension without a guard,
DO NOT operate without
one!

Older machines should not be operated without current safety guarding installed!
14] How can I quickly and easily attach/detach, transport, and store my Danuser
3-pt. hitch digger?
3-pt. hitch digger?
The Danuser Auger Cart is the right solution for you. It will transport and store your Danuser
3-pt. hitch diggers: Models F8, J20/80, G20/40, 8800, and 8900 in four easy steps. Some of its features are; one person operation, 24" maximum diameter auger, parking brake, four wheels and steering capabilities.
15] How can I make difficult digging easier?
Down
force Kits are available to make difficult
digging easier. The kits attach to all Danuser boom-type diggers
without alteration and with the use of ordinary hand tools. They
provide approximately five hundred pounds (500 lbs.) of additional down
force to the auger point for
easier penetration of hard or frozen ground.
Kits do not interfere with normal digging operations.
Kits operate with a one-way hydraulic cylinder. One line is connected to a tractor remote outlet and a second non-pressure line is connected to the hydraulic system sump directly, not through a remote outlet.

16] What are Danuser Auger Adapter Guards?
| Danuser Auger Adapter Guards are standard equipment with all Danuser Diggers. They provide protection from bolt entanglement accidents. DO NOT operate your auger without them! To prevent injury keep an area of at least twenty-five feet (25') around the auger clear of bystanders and all other people. |  |

17] Can I adapt my plain or serrated edge auger for more aggressive digging for tougher
ground conditions?
ground conditions?
| Yes. A Field Weld-on Kit is available to transform plain or serrated edge augers to Hole Digger Head Augers. A Hole Digger Head Auger will then be more aggressive as it rips through clay, caliche, shale, mixed limestone, frozen ground, and light rock. Hard-Surface Teeth are recommended for increased productivity and longevity. |  |
18] Why do I need a conversion kit for my PTO digger?
The F-series digger started in 1943. Since then we are on our 3rd PTO supplier. There are no PTO repair parts for the older diggers (prior to serial number 71,200). Danuser sells the conversion kits at a NET PRICE (our cost) to convert any older diggers with cast steel gearboxes over to the current production standards so you can obtain repair parts. The kit will also include all the current safety guarding.
19] What conversion
kit do I need if my serial number plate is missing or unreadable for my
PTO digger with a cast steel gearbox?
The conversion kit you need applies to the style of PTO you are using today.
If you have an unguarded PTO shaft, yellow metal or black metal PTO guard, and your PTO is connected to the pinion with a castle nut, you will need Conversion Kit Part ID: 7577 (for 2-3/8” diameter center column augers) or Part ID: 7580 (for 3-5/8” diameter center column augers).
If you have an E-clip style PTO where the PTO connects to the pinion with an E-clip (horseshoe looking clip), you will need Conversion Kit Part ID: 7578 (for 2-3/8” diameter center column augers) or Part ID: 7581 (for 3-5/8” diameter center column augers).
20] What conversion kit
is needed if my F-Series PTO digger with a cast steel gearbox serial
number is prior to 60,000?
Current production
Danuser F-Series PTO Diggers include Part ID: 7562 pinion
assembly. They have a black plastic Pinion Guard and black plastic
guards on the driveline,
and the driveline will be connected to the input pinion using a roll
pin.

from my auger?
The points are normal thread. You may need a pipe
wrench to loosen, as the point tightens as you dig. Always
make sure to coat the point threads with grease before installing.
