It does not include a battery or charger. The controller has a perfect battery discharge control and management mechanism. Please choose the battery and charger that meets the performance specifications of the original or secondary manufacturer. The bigger capacity the battery, the better. Please remove the battery when not in use.

Basic operation notes：
1. No automatic pressure control, same performance as plug-in Metabo drill high pressure grouting machine, maximum pressure exceeds 10,000psi, operated by a manual switch, no automatic stop.
2. In general, please turn the speed control knob to the maximum value before the operation to avoid insufficient pressure output. However,the knob can be adjusted to low-speed mode, which is suitable for speed regulation when the fine needle is used for repairing the fallen tiles.
3. When the battery is dead, the LED will flash every 1 second regardless of whether the switch is activated or not. The controller will automatically enter the pressure-limited mode and the motor will speed up slowly, but the motor can still accelerate to a high operating speed, allowing you to clean the machine. If there is no spare battery, please stop the operation, clean the machine with cleaning agents as soon as possible, or bring a standby plug-in electric drill to avoid being unable to clean the machine after a power failure.
