Before taking into use

Read and understand the contents of this manual before installing, operating, repairing, maintaining, changing accessories of this tool.

Only qualified and trained operators should install, adjust or use the tool.

Charging the battery

​Slide the battery in the charger, this should go smoothly otherwise the alignment isn't correct or the battery / charger grooves are damaged. In that case check the battery and charger and replace
the damaged item, do not repair.

​Cool down the charger when charging more than two battery packs consecutively.

Do not insert your fingers/ nails into contact hole, when holding charger or any other occasions.

​Place charger in a relatively cool and well-ventilated area.

​Plug charger into the AC outlet.  CAUTION: Ensure that the power source to be utilized conforms to the power requirement specified on the product nameplate.

​If the power lamp (red) does not light immediately or goes out soon after the charger is plugged in, consult an authorized dealer.

​During charging, the charging lamp (green) will start flashing. When charging is completed, an internal electronic switch will automatically be triggered to prevent overcharging.

​Charging will not start if the battery pack is warm. For example, immediately after heavy-duty operation. The yellow standby lamp will be flashing until the battery cools down.

​Once the battery is fully charged, the green lamp will be lit to indicate the gone into a trickle charge mode.

​When the battery is correctly installed, the red LED lights and charging starts.  The cooling fan in the charger switches on or off depending on the battery temperature. 

​LED blinking green, battery is 80 % charged  When the charging is complete, the LED lights green and you can remove the battery from the charger. 

Battery charger LED indications:  ​

​Number of cycles per battery charge, based on maximum torque on hard application ( 0.5 seconds impulsing)

YZ-T600: 1300 cylces

YZ-T800: 800 cycles

YZ-T900: 700 cycles

YZ-T950: 950 cycles
