Pre-Start

LPG tanks supplied from Exmark Do Not contain LPG fuel for shipping reasons and safety. Have the LPG tanks filled by trained and qualified personnel.

For best results, use clean, fresh HD5 grade propane.

Do Not allow the LPG tanks to be overfilled. Overfilling LPG tanks builds excess pressure within the tank which causes the relief valve to open.

Make sure you understand the controls, their locations, their functions, and their safety requirements.

Refer to the Maintenance section and perform all the necessary inspection and maintenance steps.

Operating Instructions

Raise the Rollover Protection System (ROPS)

Important: The roll bar is an integral and effective safety device. Keep the roll bar in the raised and locked position when operating the mower. Lower the roll bar temporarily only when absolutely necessary.

1.The knob must be completely latched with the tabs interlocking as shown in Figure 12 to lock the roll bar in the raised, operate position.

2.Apply forward pressure to the upper hoop of the roll bar.

3.Pull the knob and rotate 90° to hold in the unlatched position to lower the roll bar.

4.To return to the operate position, raise the roll bar, and then rotate knobs 90° so that the tabs interlock partially. Apply forward pressure to the roll bar upper hoop and observe that the knobs return to the completely latched position.
