TM5-2430-200-10 63 Operation Section Machine Operation Winch Operation Make   sure   personnel   are   clear   of   wire   rope   cable   when  there  is  a  load  on  it.  The  cable  can  break  and cause personal injury or death. Thick gloves should be worn  when working with cable. Failure to do so may cause severe injury to hands and fingers. Keep  away  from  the  winch  fairlead  when  the  cable  is retracting.    Personal    injury    due    to    pinching    at    the fairlead is possible when the winch cable is retracting. NOTICE Always   operate   the   winch   with   the   cable   in   as   straight   a   line   as   possible.   For   winching   operation   other   than   self-recovery, always operate the winch with the   tractor   in   a   stationary   position.   Moving   the   tractor   while operating the winch may damage the winch. Refer to “Machine Features, Winch Control Switches”   in this section for an explanation of the winch control switches, and “Equipment Controls, Winch Controls”   in this section for explanation of the winch clutch. The winch can be operated with the machine in either EARTHMOVING or SELF-DEPLOY modes. Use the engine accelerator pedal to control the winch speed. The rear window screen must be down when the   winch is operated. The last five wraps of cable must be left on the drum   to assist the cable clamp in holding the load. The winch has a maximum pulling capacity of 97 856 N (22,000 Ib). For loads greater than 97 856 N (22,000 Ib), use the doubling block which is stored in   the BII compartment (left compartment at the rear of   the machine). When the doubling block is used, the maximum pulling force from the doubling block hook   is 195 712 N (44,000 Ib). NOTICE The doubling block must be used when performing self- rescue of the machine. The winch should not be used to tow another DEUCE. Doubling Block Installation NOTE:   The weight of the doubling block is 23 kg   (51 Ib). 1.   Remove cotter pin (3) 2.  Turn pin (1) counterclockwise until the end of the   pin clears side plate (2). 3.  Rotate side plate (2) to allow access to sheave (4). 4.  Run winch cable (5) around the sheave. Refer to “Equipment Controls, Winch Controls” in this   section for explanation of the winch clutch. 5.  Return side plate (2) to its original position, and reinstall pin (1) and cotter pin (3).
