GEDORE WF Hickory handles High quality and extremely break-proof wood. Compared with ash the physical load stability of hickory is around 3-4 times higher Long-fibre structure More safety in the event of a handle breakage - the wood is held together by the long fibres and hence uncontrolled separation of the broken handle as well as the hammer head is avoided Vibration dampening Long life very good price-performance ratio Ash handles This wood is prescribed by the DIN as the minimum wood quality I nexpensive Break-proof Short-fibre structure the short fibres in the wood mean that in the event of a break the shaft cannot be held together. The shaft breaks into two parts. J Wood is a natural product GEDORE uses only wood types and timbers that comply with DIN 68 340 (Wooden Shafts for Impact Tools) Wood retains its natural properties even after processing Trees regulate their moisture content by giving off moisture through their pores. This property is retained in processed wood. This means that a wooden hammer shaft loses moisture through its pores when the air humidity is low and shrinks. Too much moisture causes the wooden shaft to swell up and damages the wooden fibres. DIN 68 340 defines the required moisture content of the hammer shaft at the time of joining the shaft to the head. This must be between 12 % and 14 % in relation to the dry weight. In-house manufacture under continuous quality controls guarantees compliance with the requirements of DIN 68 340 Tip Before use always check that the hammer head is securely attached to the shaft Never store the hammer in too dry conditions Storage in well-heated rooms or near a source of heat is particularly harmful drawing moisture out of the hammer shaft causing the shaft section to shrink. In extreme cases the secure fit of the hammer head on the shaft can no longer be guaranteed. STEEL TUBE FIBRE GLASS OR PLASTIC HANDLES Tubular steel handles High bending strength Resistant to the influence of weather Fibre glass handles Robust - virtually unbreakable Insensitive to all weather conditions - can also be fully used in minus temperatures and is still unbreakable Resistant to all common chemicals such as for example oils and greases Rubber grip and steel tube handle Resilient Unbeatable price-performance ratio since the hammer is very durable Vibration dampening Resistant to petrol and oil Serrated gripping zones for a firm grip Note I ntensive testing of steel tube fibre glass and plastic shafts as to a firm fit in the hammer head is required. Preference is for hammers with an additionally secured head. The head is also positively fitted to the hammer shaft by means of a spring pin. Rubber handgrip feature make sure the handgrip is firmly bonded to the shaft. Try out the turning test. A handgrip which can still be turned on the hammer shaft does not meet the DIN-prescribed figures. a Safety notes for fibre glass handles Mishits with fibre glass tools can lead to the material fibre detaching. To stop these fibres inflaming the skin we would recommend safety gloves being worn during the work. 3 Safety notes for hammers 633 QOAA 477
