LPG Cylinder Bracket
The bracket is located on the engine deck.

Fuel Gauge

This gauge monitors the amount of liquid LPG in
the fuel tank.
Safety Pressure Relief Valve
Located on the LPG fuel tank.
The safety pressure relief valve relieves the excess
pressure in the LPG tank.
Important: This valve has a protective plastic
cap that should NEVER be removed. If the
cap is damaged or missing, contact trained and
qualied personnel immediately.
Pre-Start
LPG tanks supplied from Exmark Do Not contain
LPG fuel. Have the LPG tanks lled by trained and
qualied personnel. For best results, use clean, fresh
HD5 grade propane.
Do Not allow the LPG tanks to be overlled.
Overlling 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.
