Safety Precautions
Warning: Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire, and serious personal injury. The term "POWER TOOLS" refers to electric drive electric power tools or battery-powered cordless power tools.
a) Save these instructions
- Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
- Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.
b) Electrical Safety
- Double insulated tools are equipped with a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double insulation eliminates the need for a three-wire grounded power cord and grounded power supply system.
- Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is grounded.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep the cord away from heat, oil, sharp edges, or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
- When operating a power tool outside, use an outdoor extension cord marked "W-A" or "W". These cords are rated for outdoor use and reduce the risk of electric shock.
Possible Breakdown and Troubleshooting Methods
| Cause | Solution | |
|---|---|---|
| Motor does not run | 1. The plug is not correctly inserted into the socket. 2. Poor switch contact. 3. The motor or stator coil is burned out. 4. Out of brushes. | 1. Repair circuit. 2. Check all plugs and connectors. 3. Replace motor and stator coil. 4. Replace the brush, use a new carbon brush. |
| The electric drill makes an unusual sound after being energized and the motor speed is too low. | 1. The switch contacts are burned out. 2. The mechanical part of the main motor is stuck. 3. The drill bit touched the steel bar or got stuck. 4. Debris stuck the drill bit. 5. Power supply voltage is too low. | 1. Repair or replace the switch. 2. Check and repair the mechanical part of the motor. 3. Change the drilling position and re-select the appropriate position for drilling. 4. Clean up debris from drilling. 5. Adjust power supply voltage. |
| The motor works but the impact force of the drill bit is very weak | 1. There is dust or debris in the piston, causing the air hole to be blocked. 2. The sealing ring on the piston is worn. | 1. Replace the piston, remove dust and debris. 2. Use No. 46 hydraulic oil. |
| Gearbox overheated | 1. Lack of lubricant or lubricant has been used for too long. 2. Sundries enter the gearbox, or the gear transmission effect in the gearbox is not good. | 1. Change lubricant. 2. Check the transmission part, or remove debris. |
| Excessive heat on the surface of the case | 1. Overloaded. 2. The drill bit is worn. 3. Power supply voltage is too low. | 1. Reduce power. 2. Check mechanical parts. 3. Adjust voltage. |
| Commutator produces large sparks | 1. Bad contact between brush and switch. 2. Impurities on the commutator surface. | 1. Repair poor contact. 2. Clean the commutator surface. |
| Leaking oil | 1. The hydraulic oil penetrates into the chassis through the cotton thread. The loose cotton thread causes the penetration to be too fast and oil leakage occurs. | 1. Replace cotton thread. Adjust the cotton thread as shown in the figure. Please turn the machine upside down after use. |
How to Install and Remove the PH65 Flat/Point Chisel
- First Step: Correctly adjust the position of the rodblocking so that its position is level with the base.
- Second Step: Insert the PH65 flat/point chisel into the base, then pull and rotate the rodblocking 180 degrees, which fixes the pickaxe.
- Third step: Pull the rodblocking, then rotate 180 degrees clockwise, then you can take the PH65 flat/point chisel out of the base.

P2. If your motor carbon brush looks like this, it means you can NOT use this motor carbon brush anymore, you need to change it immediately.
What to do if you find an oil leak.
- First step: Remove the screws of the fuel tank cover plate.
- Second step: Remove the four screws at the bottom. Take out the oil bowl.
- Third step: Pull out the appropriate amount of cotton thread in the middle of the oil bowl, so that the oil can penetrate smoothly through the cotton thread to the inside of the machine.
- Forth step: When an oil leak is detected, pull the cotton thread tighter to slow down the oil entering the machine.
- Fifth Step: Put the oil bowl and other parts back together as they were and add hydraulic oil #46 (L-HM46).
- Sixth step: Put the top cover parts back on as they were and tighten the screws.
Personal Safety
- Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use the tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating a power tool may result in serious personal injury.
- Use safety equipment. Always wear eye protection. A dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions. Ordinary eye protection or sunglasses are NOT eye protection.
- Avoid accidental starting. Be sure the switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents.
- Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.
- Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enable better control of the tool in unexpected situations.
- Dress properly. Do not wear loose clothing or jewelry; contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
- If devices connected with the chip removal device or dust-casting device are provided, make sure the devices are connected well. Use these devices to reduce the risks caused by the chips.
Tool Use and Care
- Do not force the tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.
- Do not use the tool if the switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
- Disconnect the plug from the power source before taking any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
- Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
- Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool's operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.
- Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edges are less likely to bind and are easier to control.
- Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool may become hazardous when used on another tool.
Maintenance and Service
- Before any work on the machine itself, pull the power plug. For safe and efficient working, always keep the machine and the ventilation slots clean.
- Tool service must be performed only by a qualified repair person. Service or maintenance performed by unqualified personnel could result in a risk of injury.
- When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance sections of this manual. Use of unauthorized parts or failure to follow Maintenance instructions may create a risk of electric shock or injury.
- Inspect the mounting screws: Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.
- Inspect the carbon brushes. The motor employs carbon brushes which are consumable parts. Since excessively worn carbon brushes can result in motor trouble, replace the carbon brushes with new ones having the same carbon brush No. shown in the figure when they become worn to or near the "wear limit". In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.
- Maintenance of the motor. The motor unit winding is the very "heart" of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.
