AND OPERATING

INSTRUCTIONS

DHS

HYDRAULIC POST

HOLE DIGGER

6.

GETTING STARTED:

Push machine to the

location of the first hole. Start engine and allow to
reach operating temperature. Standing at the rear
of the machine at the control handle. To begin
digging a hole, pull the right hand side of the
control lever. This will cause the auger to turn in a
clockwise direction. Apply downward pressure to
begin digging the hole. If dirt remains in the hole
use an up and down motion to clear excess dirt.
Release the control lever to stop auger. To 
reverse the auger rotation (counter-clockwise),
pull the left hand side of the control lever.

7. The amount of force exerted will depend on

the hardness and type of ground conditions.

8. Remember, the DHS is a single person operation,

designed for earth drilling. There may be holes that 
will be extremely difficult,if not impossible, to drill. 

9. If ground is too hard to drill or the auger is jamming

on ground conditions or foreign objects (eg. wire, 
tree roots, etc.), the pressure relief will function,
stalling the auger rotation. Clear auger and start
again. The operator presence control  will ensure
quick stop if hand is removed from control lever.

NEVER TIE OR JAM LEVER INTO THE ON
POSITION (FORWARD OR REVERSE).
REVERSE (COUNTER CLOCKWISE) MAY
BE REQUIRED TO UNSCREW JAMMED AUGERS.

10. Do not attempt to drill auger to full depth in one

operation. Continually clearing the hole in an up
and down motion will facilitate a much easier 
drilling operation. It may be necessary to clear
cutters and auger flighting from time to time to 
ensure quicker and easier cutting.

11. Remember, as in drilling a hole in steel, one needs a 

sharp drill. Auger, teeth and pilot MUST be in good 
condition if the auger is to work correctly. See wear 
parts section for more information.

12.

Auger motor head assembly may be 
tilted as per incline when drilling on 
slopes.

DO NOT

change the digger

position during drilling. 

DO NOT operate on a

slope that exceeds 15˚

13.

DO NOT

over reach. Ensure proper footing and

balance when working with this machine.

WARNING!

Keep hands and feet 

clear of all moving parts at all times!
WARNING!

Keep hands and

feet clear of exhaust muffler during
or soon after operation.

14.

WARNING!

in case of difficulty, 

release the control lever to stop 
the auger. All digging action stops.

Press the engine "STOP" button located on
the engine. (See illustration)

15.

DO

NOT OPERATE

CLOSE TO

EDGES

OR

EXCAVATIONS ETC.

CHECK FOR ELECTRICAL AND GAS

 

LINES

BEFORE DIGGING

AFTER USE

1)

Turn fuel tap to "OFF" position.

2)

Allow machine to cool down. Wash mud 

and dirt off of the hydraulic post hole digger.
Ensure no water enters the carburettor.

3) Remove any objects that may have wrapped

around the auger.

HYDRAULIC POST

 HOLE DIGGER

OPERATION

1) Remove the garden tiller 

from its trailer/carrier. 

Use caution.

2) Familiarize yourself with the machine and its

controls.

3) Ensure the safety clutch control lever is in the

disengaged position. The safety clutch

control lever is located on the left handle bar.

The disengaged position of the lever is down. 

4) Remove the shaft locking pin located behind

the wheel axle. Store pin in hole provided on

left hand side of handle bar.

5) The wheel axle will now pivot. Lift up on the

handle to allow wheel axle to pivot. For

transport, keep the wheel axle forward. When

cultivating, keep the wheel axle rearward for

added stability and control. 

DO NOT

transport the tiller with the wheel

axle in the rear position. 

6) Adjust depth shoe (if equipped) by removing

shaft locking collar and sliding depth shoe to

desired position. Replace shaft locking collar.

7)

Open fuel shut-off valve. Set choke 

control to Choke or Start position. 

Set throttle control to Run or Fast

position. Set engine

stop switch to On or

Run position. Pull

starter cord rapidly.

safety clutch control lever to stop the tynes

rotating. Tyne speed is governed by engine

throttle setting.

WARNING!

KEEP HANDS AND

FEET CLEAR OF TYNES AT ALL

TIMES!

9) Do not hurry the job. Proceed slowly and allow

the machine time to do the job. When ground

is extremely hard, reduce engine speed.

WARNING!
