TM5-3810-305-10 ALWAYS  START  AND  STOP Insufficient tire pressure reduces SWINGS   GRADUALLY. Stopping  swing  too  abruptly  will cause load to oscillate and impose side loads on boom.  This will cause damage to boom. the  “On  Tires”  capacity.  At- tempts to pick rated capacity without properly inflated tires may cause vehicle to tip and/or result in damage to tires and rims. I CAUTION I I CAUTION I Never pull to the side with a crane  boom.  Crane  booms  are not designed for excessive side pull and may collapse if sub- jected to excessive side loading. CAUTION Do not continue to pull block up after contact has been made with boom head. This will result in damage to boom head and sheaves. The cable may also be broken, causing load to drop. When spotting load, it may be necessary to alter boom length or boom  angle.  In  making  these adjustments, the operator must guard against exceeding rated load as determined by the Capac- ity Chart. Failure to follow this procedure could cause damage to equipment. Traveling over uneven terrain with rear axle oscillation locked out can result in instability. Excessive boom length can also cause instability depending on terrain  and  wind  pressure.  Fail- ure to follow this procedure could cause damage to equip- ment. I CAUTION I Never use a chromate-base corrosion inhibitor when coolant contains  ethylene  glycol.  Use only nonchromate-base inhib- itors.  Chromate-base  inhibitors reacting with ethylene glycol can produce  chromium  hydroxide, commonly known as “green slime.”  This  substance  reduces the heat transfer rate and can cause serious engine overheating. I CAUTION I Water added to battery can freeze before it mixes with electrolyte. During very cold weather, add water to battery just prior to, or during  operation  of,  vehicle.  If vehicle is not to be run, connect an external charger to battery if adding water. 1-39
