Personal injury can result when using cleaner solvents.To help prevent personal injury, follow the instructions and warnings on the cleaner solvent container before using.
Personal injury or death can result from a fire.Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire.Clean up all leaked or spilled fuel. Do not smoke while working on the fuel system.Turn the disconnect switch OFF or disconnect the battery when changing fuel filters.
Do not fill fuel filters with fuel before installing them. Contaminated fuel will cause accelerated wear to fuel system parts.
Replace upper filter (2) at every 500 service hour interval. Replace the lower filter (1) at every 250 service hour interval.This machine is equipped with two secondary spin-on filters on a single filter base. The upper filter is upside-down.

Use the following procedure in order to drain the secondary fuel filters.
Place a suitable container under the drain valves.
Drain upper filter (2) (inverted filter). Open the rear drain valve (A) first. Then, immediately open drain valve (B). Drain the fuel into a suitable container.Note: Make sure that the drain valves are opened in the proper order. If you open the wrong drain valve first, an air lock in the fuel system may occur. This will not allow fuel to drain from the upper filter.
When the fuel stops draining, keep the drain valves open. Loosen the inverted filter for 1/4 turn. As the filter is loosened, additional fuel may drain from the drain valves. When the fuel stops draining, loosen the filter for an additional 1/4 turn. Observe the flow of the fuel. Repeat this procedure until fuel does not drain from the drain valves. Close the drain valves. Properly dispose of the fuel.
If maintenance is required, remove the upper filter.If upper filter (2) is not being replaced, tighten the upper filter. Hand tighten the upper filter until the seal contacts the base. Then, tighten the upper filter for an additional 3/4 turn.Rotation index marks are positioned on the filter at 90 degree intervals. Use these rotation
