DO’S AND DON’TS

DO’S

• CHECK YOUR BELT TENSION – SLIPPING BELTS CAUSE POWER LOSS.
• CHECK YOUR 4 ENGINE MOUNTING BOLTS, LOOSE ENGINE BOLTS WILL CREATE LOOSE BELT TENSION.
• CHECK YOUR TEETH BOLTS REGULAR, TORQUETO 30 FTLBS
• 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

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
