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.

roll bar in the raised position. The upper hoop of
the roll bar may need to be pushed forward or
pulled rearward to get both knobs fully engaged
(see Figure 13).
