Summary of Contents for Rears PULBLAST A/R PUMP

  • Page 1 R E A R S Pulblast with AR pump PULBLAST A/R PUMP READ THIS MANUAL BEFORE OPERATING 06.20.18 800 547 8925 Rears Manufacturing Company Inc. www.rearsmfg.com...
  • Page 2 800 346 7867 CHEMICAL CONTAINERS INC.
  • Page 3 Sprayer Safety: Operator Tranng Safety is a primary concern in the design and manufacture of our products. Unfortunately, our efforts to provide safe equipment can be wiped out by a single careless act of an operator. READ THE OPERATOR’S MANUAL In addition to the design and configuration of equipment, hazard control and ac- cident prevention are dependent upon the awareness, concern, prudence and proper training of personnel involved in the operation, transport, maintenance and storage...
  • Page 4 Sprayer Safety: Preparaton Never operate the tractor and implement until you read and completely understand this manual, the tractor operator’s manual, and each of the safety messages found on the safety decals on the tractor and the implement. Personal protection equipment, including a hard hat, safety glasses, safety shoes, and gloves are recommended during assembly, installation, operation, adjustment, maintenance, repair, removal, or transport of this implement.
  • Page 5 Sprayer Safety: Startng & Stoppng Implement operating power is supplied from the tractor’s PTO. Refer to your tractor manual for PTO engagement and disengagement instructions. Always operate the implement at its required PTO speed: either 540 or 1000 rpm. Know how to stop the tractor and implement quickly in case of an emergency.
  • Page 6 Sprayer Safety: Chemcals Never provide agricultural chemicals to anyone unless that person has been properly trained or licensed. Make certain the entire manufacturer’s label appears on the chemical container. Always follow the manufacturer’s instructions for storage, handling, and application. Before a spraying operation is started the spray system should be rinsed and all nozzles, screens, and strainers cleaned.
  • Page 7 The skin on various body parts does not absorb pesticides at the same rate. The figure, right, illustrates skin absorption rates based on a numerical scale in which the value of 1 for the forearm represents the lowest dermal absorption rate. That value forms the basis for the assignment of values to the other body parts.
  • Page 8 Sprayer Safety: Pre-operaton Install and secure all guards and shields before starting or operating. Frequently check fan blades. They should be free of nicks and cracks. The fan guard must be kept clean and in good repair. The mechanical cabinet access guards, fan guard, sag chains, driveline shields, and gearbox shields should be used and maintained in good working condition.
  • Page 9 Be aware of the meteorological conditions and plan spray applications during op- portune times. High winds and low humidity will increase drift and adversely affect your spray program. Avoid spraying near lakes, streams, pastures, population areas (houses, schools, playgrounds, hospitals) beehives or sensitive non-target crops. Always spray downwind from these sensitive areas and do not spray during adverse wind or low humidity conditions.
  • Page 10 v Sprayer Safety: Operaton The use of this equipment is subject to certain hazards which cannot be protected against by mechanical means or product design. All operators of this equipment must read and understand this entire manual, paying particular attention to safety and operating instructions, prior to use.
  • Page 11 Do not allow riders on the implement or tractor at any time. There is no safe place for any riders. Disengage PTO and place transmission into neutral before attempting to start the engine. Do not operate unless all personnel, livestock, and pets are out of your application area.
  • Page 12 Never try to unclog a nozzle by blowing through it. Always carry extra spray tips. Never operate tractor and implement under trees with low hanging limbs: the op- erator can be knocked off the tractor and run-over. Stay alert for holes, rocks and roots in the terrain and other hidden hazards. Keep away from drop-offs.
  • Page 13 Sprayer Safety: Tres Failure to follow proper procedures when mounting a tire on a wheel or rim can produce an explosion which may result in serious injury or death. Do not attempt to mount a tire unless you have the proper equipment and experi- ence to do the job.
  • Page 14 Sprayer Safety: Mantenance Good maintenance is your responsibility. Poor maintenance is an invitation to trouble. Follow good shop practice. Keep service area clean and dry. Be sure electrical out- lets and tools are properly grounded. Use adequate light for the job at hand. Make sure there is plenty of ventilation.
  • Page 15 x When completing a maintenance or service function, make sure all safety shields and devices are installed before placing the unit back in service. Remove hydraulic pressure prior to doing any maintenance. Block the implement securely, disengage the PTO, and turn off the engine. Never use your hands or any part of your body to locate a hydraulic leak.
  • Page 16 Sprayer Safety: Transport Comply with state and local laws governing highway safety and movement of farm machinery on public roads. reflective red border fluorescent yellow/orange The use of flashing amber lights is acceptable in most localities. However, some localities prohibit their use. Local laws should be checked for all highway lighting and marking requirements.
  • Page 17 Sprayer Safety: Storage With pull-type units, never unhitch the implement without using the tongue jack. The tongue is very heavy. Attempting to lift the tongue without using the tongue jack could cause personal injury. Overloading the jack can cause failure with pos- sible serious injury or even death.
  • Page 18 Sprayer Safety: Safety Decals This is the SAFETY-ALERT symbol. This symbol is used to visibly mark operating hazards. YOU MUST FOLLOW THE DIRECTIONS POSTED BESIDE THE SAFETY-ALERT SYMBOL TO AVOID BODILY INJURY OR DEATH. Before you operate any machinery, read the operator’s manual. A copy of every SAFETY-ALERT decal on your implement is included in your operator’s manual with a map of each decal on your implement.
