TM 5-3810-306-10Section IV - OPERATION UNDER UNUSUAL CONDITIONSINTRODUCTIONThis section provides special procedures, safetyprecautions, etc. for weather conditions and modes ofoperation that are not ordinary. This section supplementsthe section "Operation Under Usual Conditions."COLD WEATHER OPERATIONNOTECold weather operation requiresadditional caution on the part of theoperator.1.Check operating procedures for cold weatherstarting.2.Don’t touch metal surfaces that could freeze you tothem.3.Clean crane, especially the boom, of all ice andsnow.4.Allow ample time for hydraulic oil to warm up.5.During freezing weather, frequently check all airtanks for water.6.Before lifting, ensure load is not frozen to ground orother surfaces.WARNINGThe use of aerosol spray or other typesof starting fluids containing ether/volatiles can cause explosions or fire.7.Use the cold weather starting aid provided for dieselengine. Refer to TM 5-3810-306-24P.CAUTIONThe drive line can be damaged whenattempting to free a frozen crane.8.In freezing weather, park crane in an area where itcannot become frozen to ground.COLD WEATHER STARTINGThe correct grade of oil for the prevailing temperatureshould be used in the crankcase to reduce hardcranking. Refer to LO 5-3810-306-12. Diesel fuel shouldhave a pour point of 10F (-12°C) less than the lowestexpected temperature. In case of emergency, DieselFuel Inhibitor, NSN 6850-00-753- 5061 may be added tothe fuel to bring the pour point down to the requiredtemperature to prevent clogging of filters and smallpassages by wax crystals. The addition of kerosene isNOT recommended for general use. If low temperaturesare ONLY expected at start-up, use the cold weatherstarting aid provided. Start crane as follows:CAUTIONDo not engage or disengage hydraulicpump with the engine running.Otherwise, damge to the pump and drivecould occur.1.Disengage hydraulic pump at disconnect.2.Position IGNITION switch to ON.3.Depress and hold both ENGINE START and quickstart pushbutton. After two seconds, release quickstart pushbutton.4.If engine does not start within 30 seconds, allowstarter to cool for one or two minutes and repeatprocedure.2-52
