1. After the circular saw is started, materials can only be sawed after normal operation. When feeding, the wood shall not shake or shake from side to side. When encountering knots, feed slowly, and the sawing length shall be no less than 500 cm. When approaching the finish line, push rod should be used to feed.
2. The deviation of the saw line should be adjusted gradually, and it is forbidden to jerk it, so as not to damage the saw blade. The saw blade should be installed concentrically with the shaft, and a safety cover must be installed above the saw blade.
3. The pressure planer must have a hand protector to prevent fingers from being planed before use. When planing, press on the wood, and your fingers must be more than 50 cm away from the plane. It is forbidden to feed wood at the back end by hand.
4. The thickness of the planed wood is less than 30cm. When the length is less than 40 cm, press it with a stick, and do not push it by hand or wear gloves.
5, shavings, sawdust and waste must be cleaned up in each shift, to ensure a clean working environment.
Second, the template installation and removal
1, shuttering should be carried out according to the previous procedure, and the next procedure cannot be carried out before the template is fixed. When ripping, the provisions of the main points of ripping should be strictly observed.
2. When dismantling the formwork with high complex structure, there should be special personnel to command and practical safety measures, and the work area should be marked below. Non-operators are strictly prohibited from entering the work area.
3. Before work, check whether the tools used are firm, and tools such as wrenches should be tied to the body. At work, the mind should focus on preventing nails from sticking and slipping off the feet.
4. Generally, a long crowbar should be used to dismantle the formwork, and it is forbidden for the operator to stand below the formwork being demolished. The upper and lower parts behind the operator must be in a safe area, and they can quickly enter the safe area when necessary to prevent the template from falling and hurting people.
5. The dismantled formwork and support shall be transported away in time or properly stacked to prevent the operator from falling due to gas-lift trampling. Before lifting the formwork, carefully check whether the binding is balanced and firm to prevent people from falling during lifting.
6. When the formwork is dismantled, the movable formwork, columns and supports shall be fixed firmly to prevent sudden degradation and collapse.
7 In case of gale, rain, snow, frost and other bad weather, outdoor operation should be stopped. After the rain and snow freeze, the construction site should be cleaned and the anti-skid work should be done well before the construction operation can be carried out.
Third, the production and installation of wooden doors and windows
1. When planing door and window materials with a planer, the thickness of the planer shall not be greater than 1 and 5mm, and no material shall be returned above the planer.
2. When changing the blade, cut off the power supply or remove the V-belt, and someone should take care of it. When grinding the saw blade, there must be a safety shield above the grinding wheel, and the safety performance of the grinding wheel should be carefully checked before operation.
3, chainsaw chainsaw around to keep clean, and equipped with fire equipment. All electric woodworking equipment must be protected one by one.
4. When installing condoms and doors and windows, you must fasten your seat belt when working high above the ground, and there must be certain protective measures in the border.
