TM5-3810-305-10Secure Hook Block1. If cable and hook block are lying on theground after completing these emergency pro-cedures, tighten cable and install wood blockon winch to retain tension on cable. Removecable from hook block socket and securecable to vehicle.Weight of the hook block isapproximately 235 lb (107 kg).Use adequate hoist and sling tolift hook block. Do not lift overpersonnel or let personnel walkunderneath suspended load.Failure to follow this procedurecould cause DEATH or seriousinjury.2. Using hoist and sling, lift hook block to toolbox for carrying purposes.Unus ualOperatingConditionSSpecial problems in maintenance and operationare caused by unusual conditions such as ex-tremes in heat, cold, humidity, high altitude, saltwater and dusty or sandy work sites. Whenoperating under such conditions, special precau-tions must be taken to prevent vehicle damage,minimize wear and avoid component deteriora-tion.Extreme ColdIn periods of extreme cold, problems of freezedamage, adequate lubrication and battery failuremay become particularly troublesome. With theonset of very cold weather, it is advisable to“winterize” the LRT 110 Crane by servicing thecooling system and switching to the lubricantrecommended for cold weather usage. Followrecommendations in this manual when operatingthe LRT 110 Crane under very extreme condi-tions.1.2.Prevent freeze damage. To prevent freezedamage to the cooling system and cracking ofengine block or head, drain and flush coolingsystem. Clean radiator exterior, makingcertain all air passages through core andcooling fins are free of foreign matter.CAUTION Never use a chromate-base corro-sion inhibitor when coolantcontains ethylene glycol. Useonly nonchromate-base inhib-itors. Chromate-base inhibitorsreacting with ethylene glycol canproduce chromium hydroxide,commonly known as “greenslime.” This substance reducesthe heat transfer rate and cancause serious engine overheating.Refill cooling system. Add an antifreeze so-lution as recommended in the amount andstrength appropriate to anticipated tempera-tures. A corrosion inhibitor is recommended.Inspect clamps, radiator hoses and radiator.Replace or repair any cooling system compo-nent found to be defective.Condensation in fuel tank contaminates thefuel supply with water. This can freeze infuel lines and block fuel flow to engine. Tominimize this possibility, keep tank as full aspossible during cold weather. This may entailrefilling tank more frequently than usual, butthe inconvenience is small compared toclearing a blocked fuel line.Check and drain the fuel/water separator. Ifwater is found in fuel tank, drain tank andrefill it with uncontaminated fuel.4-64
