must be prepared in advance. When you install and operate, pay attention to safety. Do not place the product
near explosive, flammable, corrosive materials or under humid environments.
●Installation of Cable Hook
1. Fasten the cable hook to the main body with two screws.
2. Please ensure the screws are tightened.

●Over duty protection on M1(On/OFF)
1. The actuator and the control box need to rest properly to dissipate heat, to avoid damage caused by
continuous and excessive operation. The control box has a protection function. When continuous operation is
too long or the operation frequency is too high, it will perform protection and temporarily turn off operation.
2. Active / inactive the "Over duty Protection on M1".
Press "2+" & "2-" at the same time in SET mode. “Over duty protection on M1” is ON by default and the
indicator will be on.
1. Press "1+" & "1-" at the same time and hold for 2.5 seconds in SET mode, the system will return to all default
settings. There will be a long beep.
2. Default value settings: Key tone and soft start are off, over duty protection is active, current limit is 7A.

●Battery Charging
1. After connecting the charging cable, charging will start automatically, and the LED indicator on CM42 will flash
red. The battery indicator on the HS12L hand controller will also flash at the same time.
2. When charging is completed, it will stop automatically, and the LED indicator of CM42 is continuously lit green.
The battery indicator on HS12L handset is continuously lit green as shown below.
3. After unplugging the charging cable or the AC plug, the CM42 system will process for optimization automatically.
During this time, the CM42 is still temporarily unable to operate for about 15 seconds, and the LED indicator
and HS12L battery indicator will flash continuously until it goes out to return to the normal standby state.
2. When the buzzer of the control box sounds intermittently for 4 times and stops for 4 seconds, and the LED
on CM42 flashes red at the same time, it means that the battery power is low, so as to remind the user to
charge the control box as soon as possible. After the control box enters the sleeping state and is powered off,
the buzzer reminder will temporarily turn off.
1. When the "1+" or "1-" button on the handset is pressed to control the movement of the lift actuator,
the battery level is indicated as below:

and new batteries or different brands.
Notice
• Please note that red is positive(+) pole and black is negative(-) pole.
• The battery replacement instructions in this user guide are based on the 5Ah battery as
an example, and the 2.9Ah battery polarity is opposite to the 5Ah battery (as shown in
the figure below). Please be careful to identify the battery polarity when replacing.
