TM5-3810-305-10 ing.  To  reactivate  the  system  disconnects,  retract or raise boom and/or lower hook. 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. If the operator needs to raise hook block beyond point at which the anti-two block is activated, he may override the system by using anti-two block BY-PASS switch (refer to page 4-7). 8. 9. CAUTION 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. Swing and spot load over the location where it is to be placed. When lowering light loads, be sure to maintain sufficient cable tension, preventing cable from becoming loose on cable drum. Loose cable can slip and bind suddenly, causing “jerky” lowering and shock loading  of  boom.  Loose  wraps  may  form loops which can be overlaid when cable is wound  onto  winch  drum.  These  conditions may result in personal injury or property damage. Lower load and unfasten hook. CAUTION When attaching hook block to hook block tieback, take up cable slowly while lowering boom to prevent damage to windshield. 10. Center boom over cab and raise boom to a 50-degree  angle.  Lower  hook  block  down  far enough to hook it into hook block tieback on front of the LRT 110 Crane. Lower boom to travel position while taking up slack in cable. Lift  Procedu   e r^“ On  Tires^** CAUTION l Insufficient   tire   pressure reduces the “On Tires” capacity.  Attempts  to  pick rated capacity without properly inflated tires may cause vehicle to tip and/or result in damage to tires and rims. l The  following  precautions  are necessary to prevent a “pendulum” effect of a swinging  load.  Failure  to follow these precautions can result in vehicle tipping over. Listed below are special precautions for “On Tires” lifts. Load Ratings shown in the “On Tires” portion of the Capacity Chart are based on the following conditions: 1. 2. 3. Boom shall be carried straight over front of vehicle. Travel speed shall be reduced to suit condi- tions. Specified tire pressure shall be maintained. 4-25
