OPERATION UNDER UNUSUAL CONDITIONS - (CONTINUED)
OPERATION IN EXTREME COLD
General
Extreme cold will cause lubricants to thicken or congeal; freeze batteries or prevent them from furnishing suficient
amperage for cold weather starting; crack insulation and cause electrical short circuits; prevent fuel from vaporizing
and properly combining with air to form a combustible mixture for starting. Extreme cold will also cause the various
materials or components to become hard, brittle, and easily damaged or broken. The must always be on the alert
for any indication of the effects of cold weather on the SATS. The must be very cautious when starting, towing, or
operating the SATS after a shutdown for extended periods of time. Congealed lubricants may cause failure of
parts. Tires may be frozen to the ground or frozen in the shape of a lat spot while under-inlated. Brake part may
freeze and stick in the on or off position. All of these conditions must be taken into account while operating the
SATS in extreme cold climates.
Engine
The engine is equipped with an engine block heater located on the right side of the engine. Plug the block heater
into a standard electrical outlet using an extension cord. This device will heat the engine oil which will aid during
engine startup.
Parking
Park the SATS (if possible) in a sheltered spot, out of the wind, when not in use. For longer shutdown periods, if
high and dry ground is not available, park on a footing of wooden planks. Chock in place if necessary. Also, under
conditions below -25 F (-32 C), exercise care; park the vehicle on a level surface to relieve distortion or body twist.
Battery
Ensure that battery is fully charged at all times. The battery should be removed and stored in a warm place if
the SATS is not in use.
Electrical System
Remove ice and snow from electrical components and wiring prior to starting the engine. Try not to move wiring
when cleaning since it becomes brittle with extreme cold temperature.
Exhaust System
Prior to starting the SATS in extreme cold temperatures, ensure the exhaust is clear and unobstructed.
Air Intake System
If possible remove ice from the air intake before starting the SATS. Failure to do this may result in the vehicle
not starting.
Fuel System
Service the fuel tank at more frequent intervals during extreme cold temperatures. Keep the fuel tank full during
period of nonuse to prevent condensation inside the fuel tank.
