WITH THE 3.5 INCH WIDE CUTTING TEETH. RAISE UP OUT OF THE CUT, MOVE
OVER, PLUNGE AGAIN. REPEAT ACROSS ENTIRE STUMP. MOVE SIDE TO SIDE TO
FACE OFF THE STUMP. ADJUST YOUR BOW HANDLE FOR COMFORT.
SET ONE OF YOUR WHEEL BRAKES SO YOU CAN PIVOT THE MACHINE CUT.
TO MOVE THE MACHINE FORWARD WITH THE BRAKE ON, ALLOW THE ROTATING
TEETH AGAINST THE STUMP TO PULL THE UNIT FORWARD.
TIGHTEN ALL BOLTS AND TEETH BEFORE EACH USE. TEETH ARE NOT COVERED
UNDER WARRANTY. CLEAN ALL STONES AND ROCKS AWAYS FROM CUTTING STUMP
AREA, CHECK FOR METAL STAKES AND OR NAILS IN THE TREE STUMP BEFORE
CUTTING.
KOHLER ENGINES HAVE A LOW OIL SHUTOFF TO PROTECT THE ENGINE, TILTING THE
GRINDER HIGHER THAN 12 INCHES AT AN ANGLE CAN CAUSE THE OIL TO ROLL BACK
AND THE LOW OIL SENSOR WILL SHUT THE ENGINE OFF. CUT YOUR STUMP 9 TO 10

DO’S AND DON’TS
•DO’S
•CHECK YOUR BELT TENSION –SLIPPING BELTS CAUSE POWER LOSS.

BELT TENSION.

•REMOVE THE TOW BAR WHEN GRINDING
•LIFT THE KICK STAND WHEN GRINDING
•CHANGE YOUR FIRST OIL AFTER 5 HOURS, THEN PER THE ENGINE MANUAL

•DON’T GRIND SAND, ROCKS OR DIRT, IT WILL DULL OR DAMAGE YOUR TEETH
•DONT’S
•DON’T LIFT THE FRONT END UP IN THE AIR TO WORK ON TEETH.
•When you had the nose of your grinder up in the air for extended time the oil
from the oil pan has flooded the piston cylinder and your cylinder is full of oil.
This creates compression and you can't turn the engine over. So, remove the
spark plug, remove both oil fill caps, this allows air flow. Let it sit for a day over
night is best. Replace the oil caps, give it a shot of starting fluid in the spark plug
hole, replace the spark plug. Now start your engine. It will smoke until all the oil
burns off, but it will burn off. You may even see oil from the muffler until it
burns off.
•DON’T GRIND ANYTHING BUT STUMPS
•DON’T PULL ON THE ROAD –HIGH SPEED WITH NO GREASE WILL DAMAGE YOUR
RIMS FROM HEAT. KEEP THEM GREASED.
•DON’T PULL START WITH THE KICK STAND DOWN
•DON’T START WITH YOUR TEETH ON THE GROUND
•ALWAYS
•ALWAYS CALL DK2POWER FOR AND QUESTIONS, TECHNICAL ADVICE AND PARTS.
