POWER TECH PRODUCT WARNING
Propellers are devices presenting some obvious dangers. Like many other items of everyday life, they offer many benefits,but must be used wisely. Other items such as automobile tires and bumpers, lawnmower blades, chainsaw chains, andknives fit into this category. Failure to heed the warnings presented herein or otherwise use t he product with caution can result in serious injury or death. This list is by no means complete, exercise all due care!! These propellersPropellers should always;1)Be handled carefully, using heavy gloves, body covering protection, safety
marine glasses and safety
marine shoes. The sharpedges of the propeller should be kept away from your body. The prop should not be stored in such a fashion that it coulddrop or fall upon a person.2)Be removed and/or properly covered (with durable safety covers) during boat or propeller transport or storage.3)Be used with great caution. You should always be at idle speed and minimal rpms whenever you are nearother boats,
docks, or persons.4)Not be used if the operator or passengers are under the influence of drugs or alcohol.5)Only be used by an alert, rested, properly trained operator.6)Be inspected annually and every 100 operating hours and after every impact strike. Any damage should resultin a proper repair or replacement. Propellers are subject to great stresses (as well as cavitation and impact damage) andtheir mechanical capabilities deteriorate over time. Additionally, if a mechanical flaw exists (or develops) in the propeller,it is imperative that the operator is utilizing the prop according to these guidelines, so as to avoid the risk of injury tothe operator, passengers, or others. AVOID LOCATING PERSONS IMMEDIATELY ABOVE THE PROP! Noone should ever be located above an operating prop unless the craft is equipped with a shatter shield. Propellersdo lose blades and disintegrate. No one should ever be allowed in the potential arc travel of a disintegratingpropeller. 7)Be operated with the knowledge that, as most mechanical devices, they are subject to failure. Care should betaken to ensure that, in the event of failure, all human life is protected. Examples might be to avoid; cutting in front oflarger craft, operating in close proximity to a dam or spillway, operating a craft in floods or severe storms, operating outof range of communication with rescue agencies, operating the prop near the surface of the water (exposing bystandersto danger in the event the propeller disintegrates), and
racing.8)Be supported by a backup prop, hardware, tools, and knowledge to successfully replace a failed prop. Personsnot capable of these operations should avoid situations with the potential to put themselves in harms way.9)Avoid operating the prop in mud, sand, surface penetrating operation, or any entanglements, which mightprematurely stress the propeller. If forced to operate in such a condition, extreme care is required as the prop is subjectto catastrophic failure and disintegration. Such a condition exposes nearby persons to extreme hazards .10)Be used in an area devoid of loose ropes, loose clothing, fishing lines, nets, etc which might become entangledin the prop. This poses a potential hazard to those nearby, who might be harmed by being pulled into the propeller (orwater, or other deck hazards).11)Be operated by persons over the age of 16, who are appropriately trained for the size of craft being operated.An adult should supervise operators under the age of 18. Some areas may have specific age laws, which should bespecifically followed.12)Be used only on motors properly equipped with anti-kickback devices, preventing the engine from breakingloose from its normal transom position and flipping over into the boat.13)Be used only on motors equipped with operator kill switch protection, preventing the continued operation ofthe craft if the operator is ejected. Approved flotation devices must always be worn.14)Be cleared of all persons or objects prior to engagement. Take care that on vessels of such size that the operatorcannot physically verify (while located at the operators console) the safe to start propeller condition, that a responsibleperson attends this inspection prior to authorizing the engagement of the propeller rotation.15)Be operated with passengers safely located. Special care must be taken to avoid operations with persons sitting,standing, or otherwise located near the front of the boat, in anything other than a totally secure position. This isextraordinarily hazardous in that a man overboard may be run over by the boat and prop. Always secure all personsbehind guards of sufficient height to safely retain them in the vessel.16)Be utilized at a legal speed safe for the operating conditions. Almost all craft are capable of speeds in excessof safe operating conditions. Use good judgement. Just because you can go fast doesnt mean it is safe or legal!17)Be utilized allowing adequate distance between any boat you are following. Do not allow other boats to followyour craft too closely. Allow a margin of time for recognition of a developing hazard and sufficient distance to come toa stop. Do not operate at speeds which would, in the event of a loss of control, allow you to impact otherboats, marine facilities, or bystanders. Since most marine vehicles do not possess braking devices, safe operating distancesfor collision avoidance must include adequate distance to coast to a stop.18)Be used when visibility is good. Avoid operations in poor visibility or night, without adequate navigationalequipment.19)Propeller guards may be available from aftermarket sources for your application, particularly if low speeds orrescue craft are involved. If you would like assistance, please contact our engineering staff. We also design propellersto help partially reduce some of the negative performance characteristics of propeller guards or shrouds. Propellers are made from a variety of materials including brass, bronze, stainless steel, aluminum, and plastics. Theyare typically packaged with rubber accessory members and paper/plastic packaging. Various glues or additives may alsobe used. In ordinary use for the purpose of a propeller, it poses no chemical danger to its operator or installer. However,some of the materials involved, may be cancerous or cause reproductive system toxicity, or present other health hazards,if ingested in quantities exceeding the recommended maximum levels. Avoid ingesting propellers, propeller materialbyproducts, or their related packaging and accessories. Recycle or dispose of unused propellers (and their associatedbyproducts) responsibly, in an approved recycling facility or landfill. MSDS available upon request.
