Safety Precautions1-3Operator requirementsObserve the following clothing requirements:●Wear a helmet.●Wear goggles and a particle mask.●Wear long-sleeved clothing with secure buttonsand fasteners.●Wear slip-proof shoes that are easy to walk with.●Do not wear objects that could obstruct visionwhen there is wind, or adversely affect operation(especially towels and gloves).Flying this helicopter requires a high level ofskill.The helicopter should be operated only by aperson who possesses an appropriatelicense.WARNINGCertificate of AuthorizationMake sure to wear a helmet during flight. Toperform an aerial application, make sure towear clothing that is appropriate for the oper-ation. Performing a flight and an aerial appli-cation in clothing that is not appropriate forthe task could cause loss of visibility, maneu-vering error, or cause your foot to slip, result-ing in unexpected accidents. Furthermore, itcould harm your health through exposure toagricultural chemicals.WARNINGA minimum of 3 people is required for anaerial application: a navigator who has beenbriefed on the aerial application procedure,an assistant who readies, mixes, and sup-plies agricultural chemicals, and an operator.Beware that an understaffed operation couldlead to an accident.WARNINGR-max.book Page 3 Tuesday, January 17, 2012 3:08 PM
Safety Precautions1-4The operation of an unmanned helicopterinvolves considerable mental fatigue. Theoperator should not fly the helicopter contin-uously for more than one hour, but shouldtake a rest every hour. Prolonged continuousflight operation could cause the operator tolose concentration and could lead to an acci-dent.WARNINGDo not fly the helicopter after drinking alco-hol or taking a cold medicine, or if you are inpoor physical condition. Flying the helicopterin poor physical condition could cause lossof concentration, and could lead to an acci-dent.WARNINGR-max.book Page 4 Tuesday, January 17, 2012 3:08 PM
Safety Precautions1-5When operating an unmanned helicopter for the purpose of spraying agricultural chemicals, ensure safe oper-ation, as well as the safety of humans, animals, agricultural products, and the environment during aerial appli-cation.General Flight Pattern for Aerial ApplicationExample: Disease and pest control of a rice paddy• Flight altitude: 3 to 4 m• Flying speed: 10 to 20 km/h• Flying interval: 5 or 7.5 m• Wind velocity: 3 m/s maximumSpraying PrecautionsAffirmative!Just passed 10 meters,and 5 metersFlying speed between 10 and 20 km/hFlying height between 3 and 4 metersFlying interval 5 or 7.5 metersWindWhen performing tasks such as refueling,never approach (or allow others to approach)within 20 m of the helicopter until the mainrotor has come to a complete stop and theengine has stopped. Entering within 20 m ofthe helicopter could cause a serious acci-dent.DANGERR-max.book Page 5 Tuesday, January 17, 2012 3:08 PM
Safety Precautions1-6Using Registered Agricultural ChemicalsUse nationally registered agricultural chemicals,and use them properly by reading the usageinstructions and precautions included in the manualfor each respective chemical.Do not use agricultural chemicals other thanthose registered. Failure to do so couldexpose animals, plants, or people to agricul-tural chemicals for which the operator will beheld socially responsible.WARNINGControl and handle agricultural chemicalsstrictly in accordance with their manuals.Negligent control and improper handling ofagricultural chemicals could lead to chemicalpollution or health hazards.WARNINGR-max.book Page 6 Tuesday, January 17, 2012 3:08 PM
Safety Precautions1-7Spray ChemicalSince the agricultural chemical is diluted at a lowdilution rate, make sure to observe the following:(1) Agricultural Chemical●Use nationally registered agricultural chemicals.●In low-volume liquid spraying, the characteristicsof the agricultural chemical can easily changewhen mixed with other agricultural chemicals,and may produce solids or turn to a gum-likestate. When mixing, use agricultural chemicalsthat have been checked in advance for physio-chemical change, compatibility with the sprayer,mixture toxicity, etc.●Spreading agents (surface active agents) cannotbe added.(2) Dilution WaterFor dilution water, make sure to use tap water. Donot use agricultural water, as this could lead todebris clogging or characteristic change in the agri-cultural chemical.(3) Dilution RateFor example, to make 8 of spray solution of anagricultural chemical diluted to 8x, dilute 1 ofagricultural chemical with 7 of tap water (dilutionwater). This will make 8 of spray solution.Agricultural chemical: 8 × 1/8 = 1Tap water: 8 - 1 (agricultural chemical) = 7Since flowable and water-dispersible chemicals caneasily precipitate, combine and mix them well justbefore aerial application flight.LabelAgricultural WaterTap WaterChemicalSpray SolutionTap WaterR-max.book Page 7 Tuesday, January 17, 2012 3:08 PM
Safety Precautions1-8Pouring the Spray Solution●Check the inside of the chemical tank (into whichthe solution will be poured), the check valve, thestrainer section, and the filter for any debris orsediments. If you find any debris or sediments,make sure to remove them before pouring thesolution.●Keep the chemical tank load to 8 or less perside (16 combined for left and right tanks).●For higher altitudes and temperatures,decrease the load.●For information on load capacity, see theoperation manual for the helicopter.TIPChemical TankStrainerCheck ValveFilter in the Chemical TankR-max.book Page 8 Tuesday, January 17, 2012 3:08 PM
Safety Precautions1-9Stop the engine when replenishing the chemical.When replenishing the chemical, make sure to stopthe engine. If this task takes longer than oneminute, turn OFF the main switch on the helicopter.Securely mount the chemical tanks.Prior to the flight, check that both chemical tanksare securely mounted.Do not apply excessive force on the boom.When performing tasks such as replenishing thechemical, use caution not to trip on the boom.Usage PrecautionsNever approach (or allow others to approach)within 20 m of the helicopter until the mainrotor has come to a complete stop and theengine has stopped. Entering within 20 m ofthe helicopter could cause a serious accident.DANGERIf the chemical tanks are not securelymounted, they could come off during flight.NOTICEIf an excessive force is applied against thefolding direction of the boom, it couldbecome damaged.NOTICER-max.book Page 9 Tuesday, January 17, 2012 3:08 PM
