Refer to Figure 4-9:
DANGER
!
To avoid serious injury or death:
Relieve all hydraulic pressure before disconnecting any lines
or pipes between implement and tractor hydraulic system.
WARNING
!
To avoid serious injury or death:
•
Hydraulic fluid under high pressure can penetrate the skin
and/or eyes causing a serious injury. Wear protective gloves
and safety glasses or goggles when working with hydraulic
systems. Use a piece of cardboard or wood rather than
hands when searching for leaks. A doctor familiar with this
type of injury must treat the injury within a few hours or
gangrene may result. DO NOT DELAY.
•
Always follow “Tractor Shutdown Procedure” provided in
this manual before dismounting the tractor.
The Down Pressure Kit allows for additional digging force
in hard soil by use of a hydraulic cylinder to press down
on the boom. Down pressure created is between 300 and
500 lbs. depending on mounting configuration.

IMPORTANT: Not providing some form of down
pressure relief to the hydraulic system can damage
the post hole digger and tractor when raising auger.
IMPORTANT: The “Down Pressure” relief valve is
factory set to 1500 psi and must not be changed.
Exceeding this pressure can damage equipment.
The Down Pressure Kit is ready for operating after it has
been properly installed on the Post Hole Digger (see
following pages for Assembly Instructions). This kit
should be used only on hard soils where the auger will
not penetrate the ground on its own.
Normal digging operations are made with remote control
lever for the down pressure cylinder in neutral position.
When encountering hard soil, move control lever in the
proper direction to apply pressure. When lever is held in
this position, hydraulic pressure will not exceed 1500
p.s.i. Return control lever to neutral to continue normal
digging operations.
