2 Disregard of these warnings and precaution-ary information can cause serious injury or loss of life. Procedures outlined in paragraph 1-6,AR 40-46 are M-65 Laser Range Finder is very dangerous. Looking at the laser beam or its reflection froma shiny surface can cause permanent blindness. Under non-combat conditions, the laser shallbe used only in controlled areas and at times specified by a range control officer. The laser filterin the telescopic sight shall be used in any area where lasers are in AIM-1/EXL Laser is very dangerous. Looking at the laser beam or its reflection from a shinysurface can cause permanent blindness.

3 Ensure that the laser protective cover is kept over theemitter and that the AIM power switch is off at all times when laser is not in use. Under non-com-bat conditions, the laser shall be used only in controlled areas and at times specified by a rangecontrol officer. Night goggles are required during operation and boresight ENGINEC oordinate all cockpit actions with ground observer. Ensure that rotors and blast area are clearand fire guard is OPERATIONE ngine will be started and helicopter operated only by authorized personnel. Reference HELICOPTERThe helicopter should be electrically grounded when parked and will be grounded during re-fueling 1-1520-236-10bFIRE EXTINGUISHERE xposure to high concentrations of monobromotrifluoromethane (CF3Br) extinguishing agentor decomposition products should be avoided.

4 The agent should not be allowed to come intocontact with the skin, as it may cause frostbite or low-temperature helicopter is to be parked where ambient temperature equals or exceeds 90 F (32 C), thefire extinguisher shall be removed until the next an extinguisher be left in the helicopter inadvertently during a high temperature period,the extinguisher shall be weight checked prior to the next to loading or unloading inch rockets, the wing stores power circuit breaker will weapons, or weapons being loaded or unloaded, shall be pointed in a direction whichoffers the least exposure to personnel or property in the event of an accidental firing.

5 Person-nel should remain clear of a hazardous area (forward or aft) of all loaded weapons. Rocket igni-ter arms shall remain in contact with rockets, when loaded, to reduce possibility of ignition dueto EMI (electromagnetic interference).During ground operations, when servicing the turret, the TUR SLEW switch shall be placed inGND TEST position to prevent injury to ground operations servicing personnel. Ground opera-tions servicing personnel shall be clear of dangerous areas prior to any weapons system ground run armament checks should be accomplished with the TUR SLEW rate switch inthe GND TEST position to prevent any possibility of injuries inflicted on maintenance person-nel working in the proximity of the operating aircraft and the turret REMOVAL SYSTEMG round safety pins shall be installed in pilot and gunner canopy removal arming/firing mecha-nisms when the helicopter is on the ground.

6 Pilot safety pin shall be removed prior to pins shall be installed during engine shutdown check. Debris may be expelled 50 feetoutward when system is actuated. Pilot and gunner helmet visor should be down to preventeye rotating beacon light should be turned off during flight through clouds to prevent sensa-tion of vertigo as a result of reflections of the light on the MONOXIDEWhen smoke, suspected carbon monoxide fumes, or symptoms of anoxia exist, the crewshould immediately ventilate 1-1520-236-10cFUEL, OIL AND HYDRAULIC FLUIDST urbine fuels and lubricating oils contain additives which are poisonous and readily absorbedthrough the skin.

7 Do not allow them to remain on skin longer than necessary. Prolonged con-tact may cause a skin rash. Prolonged contact with hydraulic fluid will cause burns. Refer toFM 10-68 when handling handling hydraulic fluid (MIL-H-83282), observe the following: - Prolonged contact with liquid or mist can irritate eyes and skin. - After any prolonged contact with skin, immediately wash contacted area with soap and water. If liquid contacts eyes, flush them immediately with clear water. - If liquid is swallowed, do not induce vomiting, get immediate medical attention. - Wear rubber gloves when handling liquid. If prolonged contact with mist is likely, wear an appropriate respirator.

8 - When fluid is decomposed by heating, toxic gases are electrolyte is harmful to the skin and clothing. If potassium hydroxide is spilled onclothing or other material, wash immediately with clean water. If spilled on personnel, immedi-ately start flushing the affected area with clean water. Continue flushing until medical assis-tance BLADESP ersonnel shall stay clear of turning main and tail rotor blades. Wind gusts, coast down, orcyclic movement may cause the main rotor blade to flap down below the height of a winds are created by the main rotor blades when blades are at operating LEVELS ound pressure levels in the helicopter during some operating conditions exceed the SurgeonGeneral s hearing conservation criteria as defined in TB MED 251.

9 Hearing protection devices,such as the aviator helmet, ear plugs, or ear muffs shall be worn by all personnel in and aroundthe helicopter during STORES JETTISONAll jettison safety pins shall be installed when the helicopter is on the ground. Serious injurycan result from accidental ground jettison. Safety pins shall be removed prior to flight. Failureto do so will prevent emergency jettison of wing battery power is applied, the turret gun may stow at a very rapid rate and cause 1-1520-236-10dHIGH VOLTAGES erious burns and/or electrical shock can result from contact with exposed electrical wire MATERIALSSelf-luminous dials contain radioactive materials.

10 If such an instrument is broken or becomesunsealed, avoid personnel MISSILE FIRINGD uring night TOW missile firing, AN/AVS 6 NVGs should be utilized due to the increased mar-gin of safety provided when compared to the AN/PVS 5 Interference (EMI) can interfere with missile guidance. Avoidance require-ments are contained in HIRTA messages. Pilots shall be briefed and familiar with these require-ments. Firing of TOW missiles in a high EMI area should be avoided if of the FLIR optics inside the C-NITE telescopic sight unit (TSU) have a coating that isradioactive. Accidental inhaling or swallowing of this material is hazardous to health.
