Electric hammer operation and maintenance regulations
1. Before homework.
1.1 Confirm whether the power supply used matches the specifications indicated on the tool nameplate.
1.2 Confirm whether the power switch is turned off. If the power switch is turned on, the power tool will unexpectedly turn immediately when the plug is inserted into the power outlet, thereby causing a serious accident. 1.3 If the work place is moved to a place away from the power source, use sufficient capacity, install suitable extension cables, and keep it as short as possible
2. Pay attention when using.
2.1. Safety glasses should be worn to protect the eyes.
2.2. Wear a protective mask when working with the face up.
2.3. Keep earplugs in place to reduce the effect of mocking.
2.4. The bit holder should be properly installed.
2.5. During the operation, the bit should be in a hot state, and care should be taken.
2.6. The side handle should be used during operation.
2.7. Only with good posture can safe operations be implemented.
2.8. When starting the operation, first confirm whether the grease is normally supplied and whether the screws are properly tightened.
2.9. Pay attention to the contents and the safety of pedestrians when working above height.
2.10 When drilling ceilings and floors, you should first confirm whether there are buried cable workers. .
3. Operation
3.1. Drilling method
A. Put the drill bit in the drilling position, and then pull the switch trigger.
B. The hammer drill only needs to be slightly pressed to allow the chips to be freely discharged, and it does not need to be pushed hard.
3.2 Chiseling and crushing Put the drill bit in the location of chiseling and crushing, and use the weight of the drill to perform the operation. When working, there is no need to push hard. Drilling and driving with self-drilling anchors When using self-drilling anchors, the anchors can be driven in.
Electric hammer operation and maintenance regulations
At this time, you must use various optional attachments for self-drilling anchors such as anchor attachments.
3.2.1 Using impact anchor attachment
a. Put the rotating wooden handle on the anchor bolt attachment, and then make a base hole in the drilled part after the impact. At the same time, use the operation to rotate the handle at the stage, the plug is not yet loaded on the anchor bolt.
b. After reaching the predetermined depth, temporarily pull out the anchor.
c. Use an ejector to blow off the chips.
d. Install the plug on the anchor bolt and continue driving into the anchor bolt with a hammer drill.
e. After driving the anchor bolt, use the DRIFTKEY to separate the anchor bolt
f. Use a hammer or pliers to release the taper of the anchor bolt.
3.2.3 Using rotary drill and impact anchor attachment
a. Assemble the self-drilling anchor to the anchor attachment.
b. Turn on the switch and drill the base hole with self-drilling anchor. When starting drilling, the drill should be tilted slightly to determine the hole position.
c. After removing the chips with the ejector, fit the plug to the tip of the anchor, and then hit the plug with a hammer.
d. And the operation of cutting items. At this time, the anchor bolt attachment must be used.
3.2.4 Using the taper shank attachment
a. Install the bit together with the taper shank on the taper shank attachment.
b. Connect the shape and drill until it reaches the depth of the marked groove.
c. After removing the tip of the chip with an ejector, install the plug on the tip of the anchor bolt and drive the anchor bolt with a hammer or pliers.
4. Maintenance
4.1. Check the drill bit: Using a dull drill bit will make the motor work abnormally and reduce the operation efficiency. Therefore, if the drill bit is found to be significantly worn, it should be replaced with a new one immediately, or be sharpened quickly.
4.2. Check the installation screws: Always check whether the installation screws are tight. If it is found that the screw is loose, it should be retightened immediately, otherwise it will cause a serious accident.
4.3. Maintenance of the motor: The winding of the motor is the heart of the power tool. Care should be taken to check for damage and whether it is wetted by oil or water.
4.4. Check the carbon brush: The carbon brush on the motor is a consumable. Once the wear level exceeds the "wear limit", the motor will malfunction. Therefore, worn carbon brushes should be replaced with new ones immediately. In addition, the carbon brush must always be kept clean so that it can slide freely in the brush holder.
Replacement steps: Remove the tail cover and brush cover, the carbon brush can be removed separately. 4.5. Check the dust cover: The dust cover is designed to prevent dust from entering the internal mechanism. If the inside of the dust cover is worn out, it should be replaced immediately. The dust cover can be removed as soon as it is pulled.
1.1 Confirm whether the power supply used matches the specifications indicated on the tool nameplate.
1.2 Confirm whether the power switch is turned off.
