10.Latch the bracket and make sure the tank is securely fastened to the mower.

11.Carefully connect the fuel hose; the threads are LH. Make sure the hose is not kinked.

12.Slowly open the fuel valve to equalize the pressure in the tank. If the fuel valve is opened too quickly, the pressure relief valve is equipped with a back pressure check valve that will shut off the fuel supply. If this happens, close the fuel valve completely and wait five seconds. Slowly open the fuel valve.

13.Check for leaks as described in the Inspection section in Safety.

Exmark Premium Hydro Oil is recommended. Refer to the chart for an acceptable alternative:

5.Loosen filter 1/2 turn and allow a small amount of oil to leak from the oil filter (this allows air to be purged from the oil filter and supply hose from the hydraulic reservoir). Turn filter clockwise until rubber seal contacts the filter adapter. Then tighten the filter an additional 2/3 to 3/4 turn.

6.Raise the rear of machine up and support with jack stands (or equivalent support) just high enough to allow drive wheels to turn freely.

7.If either drive wheel does not rotate, one or both of the charge pumps (located on the top of the main pump as shown in Figure 15) may have lost their “prime”. Refer to Hydraulic System Air Purge section.
