Operation
WARNING: Read and thoroughly understand all instructions
and safety information before assembling or operating this post
hole digger. Failure to do so may cause serious injury or death.
1. In a separate container mix gasoline and 2-cycle engine oil
in a ration of 25 parts gasoline to one part 2-cycle engine oil
(approximately 1 gallon of gas to 2.5 fluid ounces oil). Mix
thoroughly before adding to the post hole digger’s fuel tank.
2. Turn the engine switch on the right handle bar to the ON
position (backwards).
3. Slide the choke level to the choke position.
4. Press the fuel priming bulb three or four times.
5. Pull the recoil handle slowly and release.
6. Pull the recoil handle quickly to start engine.
7. Allow the engine to run for a few minutes
then move choke to the run position.
8. Lower the auger to the ground at the desired angle for hole
digging.
9. Engage the power trigger to start digging at a slow speed
lowering the auger slowly as the hole is dug. Increase the
speed as the auger goes deeper into the ground by depressing
the power trigger further. e type of soil will determine the
proper auger speed. A very hard or compacted soil may require
operation at varying speeds to be the most efficient in digging.
10. After the desired hole depth has been reached, spin the auger
at a high speed to clear the hole of soil. Reduce the speed
before withdrawing the auger from the hole by easing up on
the power trigger, then releasing the power trigger entirely.
STOP THE AUGER BY PUSHING THE
ENGINE ON/OFF SWITCH FORWARDS
If a rock or other obstacle is encountered that is too large for the
auger to displace the post hole digger will begin to vibrate. Slowly
withdraw the auger from the hole completely. Push the engine
on/off switch forward to stop the engine and remove the obstacle
manually. Slowly lower the auger into the hole and engage the
power to complete digging the hole.
