EXTREME ENVIRONMENTAL MAINTENANCE
2-12. UNUSUAL CONDITIONS
Towing. The cart may be towed by a tow vehicle at a maximum speed of 15 miles per hour to any location on
good roads. The cart has a clearance of five inches if towed over rough terrain.
Extremes of heat and cold. The cart is designed to operate in temperatures ranging from -20 degrees F to +160
Other unusual conditions.
When operating the cart in extreme conditions of snow, ice, rain, mud, dust, salt air or similar conditions,
do everything possible to prevent foreign material from entering the nitrogen tank connector nipples. This
may clog in-line filters and cause reduced booster pump performance.
After operation in extreme conditions, thoroughly clean and dry the cart and its accessories. Perform the
filter inspection procedures per paragraph 3-25 "Tank Connector Assembly Inspect and Replace" and 3-26
"Tank Connector Assembly Inspecting and Replacing Components". Replace the tank connector nipples
and the high pressure filter (F2) if necessary.
Frequent over the road service or submersion requires wheel bearing maintenance.
If the cart has been connected to contaminated shop air and performance has degraded, replace the low
pressure filter (F1).
