1. Main safety instructions for electric slotting machines 1. Do not slot on live walls: avoid limited cables, gas pipelines, natural gas pipelines, water pipes, etc. that may be charged when grooving as much as possible. 2. Avoid: Do not touch the working head (pressure plate, saw blade and output shaft) of the machine that has just finished work, it is easy. 3. Waterproof into the motor: Mainly do not let water enter the motor part, otherwise it is easy to be electrocuted. 4. Pay attention to maintenance tools: clean up the dirt in time after the tool is used to prevent the faucet from being blocked. 5. Cannot lift the machine directly with a cable: Direct lifting of the machine can easily cause the machine to not be energized or even short-circuited. 6. Pay attention to the workplace environment: tools should not rain, do not use in places with dangerous goods 7. Do not pedal wires: do not pedal wires or pull wires out plugs, etc., and avoid touching hot and sharp metal edges or getting wet with grease. 8. The power plug must be unplugged for any maintenance of the machine, including cleaning dust, replacing saw blades, etc. 2. Scope of application and machine parameters This machine can be used for slotting walls or floors such as solid brick, honeycomb brick, gravel concrete, polished brick, glazed tile, etc. Machine parameters back 220V~, 2500W, 8500 rev/min, saw blade inner hole 22.23 outer circle 150 or 125 with 125 saw blade: slotting depth: 10.20.30 slotting width: 2.5~38 with 150 saw blade: slotting depth: 22.32.42 slotting width: 2.5~38 three, machine features and precautions 1, our machine It is a pull-type slotting, which cannot be pushed forward, but can only be pulled backwards; so pay special attention to the method of slotting: when changing the switch, the red wire must be red to the red line, and the blue line to the blue line, otherwise it will cause a short circuit!!! 2. The machine has two handles that are perpendicular to each other for horizontal and vertical grooving. The main force is sufficient, which can be convenient for vertical slotting. 3. The machine switch is an anti-lock switch. When pneumatic, you need to use your index finger to lift the small button on the switch to close the switch. The machine starts working, even if the switch is not pressed, it can work continuously. To stop it, you need to press the main switch button again. Craftsmen who are not familiar with the switch performance just got the machine need to experience it. 4. Operation steps Saw blade installation 1. Select the saw blade type 150 or 125 and the number of saw blades according to the width and depth of grooving as needed. Special remarks If you select 150 saw blades, you need to replace the 125 dust guide plate inside the saw blade cavity to ensure smooth dust removal. Note that the inner hole of the saw blade is 22.2, and installed well, the cutting depth of the 125 saw blade is 30,150, the cutting depth of the saw blade is 42.2. 2, remove the upper one of the inner M5 hex screws that press the protective cover, and then loosen (but not remove) the lower one of the hexagon screws that press the protective cover, and unscrew the protective cover. 3. Remove the deep standard size assembly (front hand wheel) and locking assembly (rear hand wheel), and pull the floor open. 4. Press the self-locking button, use a special handle to loosen the upper pressure plate (pressure plate with holes and threads), exit all the lower pressure plate (flat pressure plate), first put on the saw blade, that is, the blade blade is directly installed on the output shaft, then the lower pressure plate is installed, and then the saw blade is installed, and so on, until the required groove width is reached, in the installation of the appropriate number of lower pressure plates (to ensure that the upper pressure plate can be pressed tight saw blade), install the upper pressure plate (positive screw in ), and use a special handle with self-locking to tighten the saw blade. The upper pressure plate can be directly under the saw blade, and there is no need to have a flat pressure plate. 5, the replacement of the saw blade also adopts the handle and self-locking only the handle rotation direction is opposite (reverse rotation out) When the dust guide plate machine leaves the factory, 150 dust guide plate is installed, it is matched with 150 saw blade; if you want to install 125 saw blade, need to replace the matching 125 dust guide plate, so that the dust removal effect is more effective, if you feel troublesome to replace the dust guide plate, you can also not change, replace the dust guide plate method As follows: 1. Remove the three M5 screws 2. Use the hexagon handle to stick them in from the screw hole, remove the screws that have been installed with the dust guide plate, and then the dust guide plate and screw can be taken out of the saw blade cavity. 3. Select the required dust guide plate, and insert two hexagon screws, and insert the dust guide plate from the saw blade cavity hole. 4. Install the three external screws and tighten them. Adjust the cutting depth to loosen the front and rear two plastic nuts, and open the front and rear two cards, so that the bottom plate can be pulled out, so that after selecting the slotting depth, re-snap the card into the front and rear positioning slots, and tighten the plastic nuts.
