2010 Mack Natural Gas MRU,LEU: BEFORE PERFORMING MAINTENANCE ON THE LNG OR CNG TANKS OR FUEL SYSTEM

Use this checklist before doing any maintenance on your Mack truck. Performing regular maintenance on your equipment has been proven to reduce repair costs for trucks and to avoid unnecessary damages.

    Note: Separate methane detector/alarm systems should be installed in facilities that frequently house LNG/CNG vehicles. In addition, hand-held methane detector/ alarm devices should be used when working on LNG/ CNG vehicles with a non-functioning or disconnected methane detector/alarm system and where no auxiliary methane detector/alarm system is installed.

    Note: If possible, try to service the tanks after the vehicle has used most of its on-board fuel.
