OPERATION

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 o, but it will burn o. You may even see oil

from the muer until it burns o.

• 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 DK2 POWER for and questions, technical advice and parts

USE DK2 POWER OEM REPLACEMENT BELTS FOR TOP PERFORMANCE.
