OPERATION

BEFORE STARTING
CLEAR AREA OF ALL PEOPLE AND PROPERTY THAT COULD BE DAMAGED. THINK SAFELY. CHIPS ARE FLYING 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 CHIP WOOD, CHILDREN SHOULD NOT RUN THIS EQUIPMENT, STAY ALERT OF YOUR SURROUNDING AND PERSONS THAT COULD APPEAR IN THE CHIP PATH WHILE YOU ARE WORKING. UNIT IS A DIRECT DUAL BELT DRIVE. NO CLUTCH TO SLIP OR BURN UP BUT YOUR BELTS WILL NEED TO BE TIGHTENED AND CHECKED ON A REGULAR BASIS TO MAINTAIN 100% CUTTING POWER.

PERFORMANCE OPERATION
APPROACH STUMP FROM THE TOP CUTTING STRAIGHT DOWN INTO THE STUMP WITH THE 3.5 INCH WIDE CUTTING TEETH. RAISE UP OUT OF THE CUT, MOVE OVER, PLUNGE AGAIN. REPEAT ACROSS THE 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 AWAY 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 INCHES OFF THE GROUND SO YOU DON’T TRIP THE SENSOR ON THE ENGINE. READ AND OBEY ALL WARNING LABELS ON THIS MACHINE.

QUICK START & TROUBLESHOOTING

QUICK START SETUP

  •  Add 10W30 oil to engine
  •  Add gas
  •  Pin one wheel into pivot brake hole, other wheel free turning
  •  Raise up kick stand
  •  Turn key on
  •  Half throttle (choke optional for cold starts)
  •  Tip the unit back with the cutters off the ground
  •  Pull start the engine

STUMP CUTTING

  •  Engine on highest speed
  •  Hold tight on bow handle with both hands
  •  Lower cutters into top of stump, cut 3.5” wide to cutter depth
  •  Raise cutters up and move over for next cut, repeat
  •  Pivot cutters from side to side to face off remaining stump

TROUBLE SHOOTING

ENGINE WON’T START

  •  Turn key on – check engine oil level – check gas level
  •  Unplug key switch – if engine starts replace the key switch
  •  Follow your engine manual for further trouble shooting

UNIT VIBRATES

  •  Check your cutters for missing or loose teeth
  •  Check your cutter wheel pillar bearing mounting bolts

ADJUSTING THE DRIVE BELTS

POWER LOSS AT CUTTER WHEEL

  •  Check your belt tension – slipping belts cause power loss
  •  Worn belts – replace
  •  Belt tension should be set at .25 inch movement above and below belt normal position
  •  Check your 4 engine mounting bolts, loose engine bolts will create loose belt tension

DO’S & DON’TS

DO’S

  •  Check your belt tension – slipping belts cause power loss
  •  Check your 4 engine mounting bolts, loose engine bolts will create loos belt tension
  •  Check your teeth bolts regularly, torque to 30 ft lbs
  •  Grease your tire axles
  •  Remove the tow bar when grinding
  •  Lift the kick stand when grinding
  •  Change your first oil after 5 hours, then per the engine manual
  •  Use DK2 POWER OEM Replacement Parts for Top Performance
  •  Don’t grind sand, rocks or dirt, it will dull or damage your teeth

DON’TS

  •  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 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

USE DK2 POWER OEM REPLACEMENT BELTS FOR TOP PERFORMANCE.

  1.  Add gas mid grade and 10W30 oil to either one of the yellow plugs
  2.  Your grinder won’t start on low oil. Make sure your oil is full – halfway up the filler neck
  3.  Kick stand up
  4.  Engine gas paddle on full to the right (located on the air cleaner)
  5.  Choke in the middle
  6.  Speed on turtle
  7.  Turn your key on
  8.  Teeth on the ground
  9. Pull start
