Operation Instructions

BEFORE TURNING KEY AND PULL STARTING ENGINE:

Clear the area of all people and property that could be damaged. Think safety. Stones from the soil can be projectiles and can cause injury.
Wear safety glasses, hearing protection, and gloves.
Do not wear loose fitting clothes that could get stuck in the machine moving parts.
Only trench soil and sand.
Children should not operate this equipment.
Stay alert of your surroundings and persons that could appear in the digger path while you are working.
Never approach the auger or chain while running – turn the trencher OFF.

BEFORE YOU DIG: Have the area verified for any utilities in the ground, such as buried electrical lines, gas lines, etc.

Operation:

Tip the unit back, lower the cutting chain to the desired depth. There are 5 levels set by the hand lever on the handle grip.
Make sure the forward brake is lowered into the wheel brake gears. Loosen the center bolt in the brake bar to set the FORWARD brake system before digging. This will hold your trencher from moving forward while digging. The unit will roll free in reverse pull.
Tighten the bolt to release the dual wheel brakes so your unit will roll freely for transportation.

PERFORMANCE OPERATION:

Your trencher has quick change teeth. The digger points snap out by tapping with a hammer and replacements snap back into the socket. Use a block of wood when replacing the teeth. Never strike the cutting tips with a hammer.
Lock your machine and remove the keys when not in use to protect the machine from unauthorized use.

All parts are available from DK2POWER at 702-331-5353.
