Maintenance
Fuel Tank - Drain
1. Clean the fittings and tank.
2. Place the machine on level ground.
3. Expand the tracks out.
4. Place a container on the ground under the fuel tank drain
plug (1). The drain plug is located below the fuel tank.
5. Remove the plug and fuel cap and allow the fuel to drain
into the container.
6. Replace and tighten the drain plug.
Fuel System Water Separator -
Drain
Water is heavier than diesel fuel and will settle to the bottom
of the bowl. WITH THE ENGINE OFF, drain the water by
opening the self-venting drain valve (2) and allowing all water
to escape. Drain the fuel/water with appropriate container and
dispose of according to local regulations, and enviromental
protection laws. Close the drain and reprime the element as
described in the Cummins Manual.
Fuel System Water Separator -
Element
Element replacement frequency is determined by the
contamination level in fuels. Fuel flow to the engine becomes
restricted as the element gradually plugs with contaminants,
resulting in noticeable power loss and/or hard starting.
When any one of these occurs, change the element as soon
as possible. Always carry an extra replacement element (See
service parts), as one tankful of contaminated fuel can plug a
fuel filter. For instructions regarding the element replacement
see your Cummins Engine Manual.
Hydraulic Oil - Check & Fill
The hydraulic oil tank(3) and fill neck (6) are integrated into
the frame on the left side of the machine under the hood.
Check your hydraulic oil level daily before use. Check the
oil level only when the machine on level ground. The oil level
sight gauge (4) is located on the tank’s rear face.
NOTICE
Dispose of any drained fuel according to local
environment protection regulations.
