Sudden  movement  of  the  machine  can  cause  injury  to persons on or near the machine. To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating the machine. NOTICE Care  must  be  taken  to  ensure  that  fluids  are  contained during  performance  of  inspection,  maintenance,  testing, adjusting and repair of the product.  Be prepared to collect the   fluid   with   suitable   containers   before   opening   any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose  of  all  fluids  according  to  local  regulations  and mandates. NOTICE To  avoid  damage  to  the  vibratory  system  during  testing, always perform the testing with the vibratory drum on top of   tires   or   on   loose   dirt.      Tires   will   simulate   a   non- compacted soil condition. Never  operate  the  vibratory  system  when  the  machine  is on concrete. NOTICE If a testing time longer than three (3) minutes is required, rotate   the   drum   periodically   in   order   to   lubricate   the eccentric weight shaft bearings. NOTE:    The  hydraulic  oil  temperature  should  be  at  least 38° C (100° F). 1. Make sure that the parking brake is applied.  Make sure that the propel control lever is in neutral.  Make sure that the vibratory on/off control on the propel control lever is in the OFF position. Illustration 57 End of Drum (1) Vibratory motor.  (2) Drain line.  (3) Flushing valve. 2. Disconnect drain line (2) from vibratory motor (1). 3. Install 90 cm (36 in) of 9X-2350 Hose and 4C-8689 Flow Meter (5) between vibratory motor (1) and drain line (2). 4. Install  4C-6500  Digital  Thermometer  into  the  hydraulic oil tank. 5. Move    the    vibratory    amplitude    control    to    the    LOW AMPLITUDE position. 6. Start the engine and run the machine at high idle until the   hydraulic   oil   temperature   reaches   38 C   (100F). Engine speed should be 2350 50 rpm. 11-53
