UNDERSTAND SIGNAL WORDS
Note the use of the signal words DANGER, WARNING
and CAUTION with the safety messages. The
appropriate signal word for each has been selected
using the following guidelines:
DANGER: Indicates an imminently hazardous situation
that, if not avoided, will result in death or serious injury.
This signal word is to be limited to the most extreme
situations typically for machine components which, for
functional purposes, cannot be guarded.
If you have questions not answered in this manual or require additional copies or the manual is damaged, please
contact your dealer or the manufacturer directly.
WARNING: Indicates a potentially hazardous sit-
uation that, if not avoided, could result in death
or serious injury, and includes hazards that are
exposed when guards are removed. It may also
be used to alert against unsafe practices.
CAUTION: Indicates a potentially hazardous sit-
uation that, if not avoided, may result in minor or
moderate injury. It may also be used to alert
against unsafe practices.
DOWN FORCE KIT INSTRUCTIONS
INSTALLATION
KIT #170810 DFK-50
(FOR MODEL 300 POST HOLE DIGGER)
ATTENTION! Tractor must have auxiliary hydraulic outlet
to operate this hydraulic down pressure kit.
If your tractor does not have this outlet, check with your tractor dealer.
1. Refer to the parts illustration and install the Down
Force Kit parts as shown. The pin attaching the
boom to the yoke is replaced by a
3
/
4
- 10 NC x 6”
lg. hex head bolt and lock nut.
2. Use a good grade hydraulic thread sealant and
install the hydraulic components. Do not use Teflon
tape!
3. Install the hydraulic cylinder and boom clamp. The
cylinder rod should be retracted and the boom
clamp installed loosely so that it can slip on the
boom. Raise the Post Hole Digger to its full up posi-
tion. Now tighten the boom clamp bolts to 300 ft.
lbs. torque. It may be necessary to retighten the
clamp bolts after initial use to keep the clamp from
slipping.
4. Connect the pressure hose (item #15) to one of the
tractor remote outlets.
5. Connect the return hose (item # 16) directly to the
tractor hydraulic reservoir fill opening. NOTE: DO
NOT CONNECT THE RETURN HOSE TO A
REMOTE OUTLET. The remote outlet valve ports
are blocked in the neutral position and will damage
the hydraulic cylinder or other parts when the boom
is raised.
OPERATION
Lower the Post Hole Digger in the usual manner
and allow the auger to dig. As down force is needed,
apply it carefully and in small amounts by using the
control lever on the tractor remote outlet. It will be
necessary to continue lowering the lift arms as the
auger digs. Applying too much down force at one time
can stall the auger and possibly cause the shear bolt
on the post hole digger input shaft to shear. NOTE:
REPLACE THE SHEAR BOLT WITH A GRADE #2
(SOFT) BOLT ONLY. Using a (HARD) bolt can dam-
age the auger, PTO driveline or gearbox and void the
warranty.
The boom can be raised in the normal manner with-
out relieving the down force cylinder pressure.
NOTE: DAMAGE CAN OCCUR IF HOSES ARE
NOT CONNECTED CORRECTLY. If the return
hydraulic hose is connected to the other tractor
remote outlet instead of directly to the tractor
hydraulic reservoir, severe damage will possibly occur
to the hydraulic cylinder and post hole digger when
the boom is raised. Make sure hydraulic hoses are
connected correctly.
