A. Engine Service

NOTE: Engine service and maintenance refer to Engine Manufacturer Operator's Manual.

B. Cleaning Instructions

Keep your kart clean by using a clean rag and a mild detergent and water solution . Wipe off all dirt and oil from around the controls . Wipe off any spilled fuel and oil . Keep the

engine clean and clear of foreign objects, especially those around the air intake fan and air inlet ductwork .

C. General lubrication

Lubricate the vehicle at least every 90 days, and more often, if the kart is used daily or in unusually dusty conditions .

D. Chain Lubrication and Adjustment

For optimum chain life, lubrication with a spray on chain lubricant should be performed on a regular basis . DO NOT USE OTHER OILS .

figure 2 .5

A new chain will stretch within the first few hours of use and therefore will require adjustment . The first chain adjustment should be made after the first 2 hours of use . If the

chain has more than ½" of slack or "flex" then it will require adjustment . To adjust:

1) Loosen nut 1

2) Adjust nut 2 until the proper chain tension is achieved

3) Re-tighten nut 1

E. Belt Replacement

Ensure the kart is on a smooth flat surface and the engine is OFF . Apply parking brake . Remove the three mounting bolts for the belt cover . Remove mounting screw located

behind the belt cover at the bottom . Using a ½" socket or box wrench, remove the drive (front) pulley mounting bolt and pull the pulley off the crank shaft . If the existing belt

is still in tact, remove existing belt . If not, look for anything that may have caused the belt to fail prematurely . Inspect and clean pulley with dry cloth or compressed air . Install

new belt with the tapered edge away from the engine . Place belt around the driven (rear) pulley and stretch over the crank shaft and onto the spanner . Replace the drive

pulley and mounting bolt . Tighten bolt to 30 ftlb .

F. Storage Instructions

If you plan to store (and not operate) your kart for a period in excess of 30 days, or at the end of each driving season, the unit should be set up for storage as follows:

1) Drain fuel tank and carburetor by allowing the engine to run completely out of fuel .

2) Lubricate the engine cylinder by using an engine fogging oil, following the instructions provided with the product .

3) Do NOT save or store gasoline over the winter . Using old gasoline, which will deteriorate from storage, will make the engine difficult to start and affect the

performance of the engine .

4) To protect the paint, plastics and upholstery, it is a good idea to keep the unit covered when not in use .
