Proof curved handle, maintenance wrench series proof tools: 1, in our daily work struck 20 times in a row on the surface of the attachment tool should be treated, Kaijing before making use, do not continuous use, Because for a long time in order to avoid friction causes heat tool, so there might damage our tools products. 2, after use to wipe the surface dirt and deposits, place a dry safe place to save. 3. Striking Tools products, not continuous, with more than ten times should be appropriate interval, while the timely removal of adhesive products, parts debris before you continue. 4, Wrenches non-super-power use, but can not be strapped with a casing or other metal sticks longer arm and hammer percussion (except tap wrenches) method knob fasteners. 5. Tools should be placed on the sink were grinding wheel lightly touching, not too much force and the contact wheel too long. 6, in the hit knocked the actual operation tools, debris must be removed and the face corrosion oxide, to prevent a third party impact. Based on the above performance and use that in the normal course of an aluminum-copper alloy is more suitable for pressure equipment and explosion-proof requirements less stringent environmental conditions (such as gas stations, small oil tanks, etc.). The beryllium copper alloy applicability of proof tools (such as refineries, gas transfer stations, gas plants, drilling crew, etc.). 7, a variety of products before use to remove surface oil, according to the instructions to use reference tool steel. Intrinsically Safe, copper explosion of human electrostatic discharge device. For petroleum, chemical, gas, coal, gas, oil tank area, gas tank area, a hydrogen production plant, and other flammable plant. Easy installation, zero maintenance. Welcome. ,
