Changing Engine Oil
  1. Park RTV on level surface and lift the bed

  2. Remove drain plug from bottom of the engine while engine is still somewhat warm (allow plenty of time for engine to cool down so that oil is not hot) to drain oil into oil pan

  3. Put drain plug back in when oil has drained

  4. Fill with new oil to the upper groove of the dispstick

Oil Capacity:

Cleaning the Primary (Outer) Air Filter
  1. Remove air cleaner cover and primary filter

  2. Cleaning the filter:

    -If filter only contains dust: Blow compressed air (under 30psi) from the inside of the filter to clean it.

    -If filter contains carbon or oil: Soak filter in detergent for 15 minutes, wash and rinse with water and let it air dry. When filter has completely dried, use a light to check for damage.

  3. Reinstall filter and cover

  4. Check evacuator valve for blockage

  5. Check rubber seal and replace it if it is damaged

Replace the air filter yearly, or after every 6th cleaning, whichever comes first.

Do not touch secondary (inner) filter unless you are replacing it. If dirt is found on the inter filter replace both filters immediately.

Evacuator valve should be opened once a week, or daily when used in a dusty place, in order to get rid of larger dust particles.

Checking Fuel Line and Fuel Filter

  1. Park RTV on a level surface and raise the bed

  2. Inspect fuel lines and pipe clamps for damage or deterioration. Replace them if damaged.

  3. Check to see if fuel filter is clogged or contains water. If either is true replace it.

Fuel lines and clamps should be inspected annually, or after every 100 hours of use, whichever comes first.

Be sure to close off the end of a fuel line whenever it is disconnected so dirt does not get into it.
