How to make the batteries perform longer
We ought to possess the common knowledge of caring for battery pack in use. In other word, we might concern with how to extend the useful life of battery pack as below.
1. New battery packs normally should be treated no charged at all or only charged of 20% power before shipment in order to avoid battery’s crashing or chaotic vibration in
transit that might subsequently result in a short circuit of battery pack
2. Do not repeat charges for Ni-Cd and Ni-Mh battery pack as its remaining power is still available. Otherwise, battery pack will have memory effect that might result in reducing
charging capacity.
3. In order to increase charging capacity and the useful life of battery pack, please discharge the remaining power first and re-charge the battery pack for continuous 24-hour
whenever the user charges the battery pack in first time OR re-use the battery pack again after more than one-month’s idle placement.
WARNING! Place battery pack inside the house (temperature between 10°C ~40°C ) for one-hour first before charging, if the battery pack is stored under 10°C! If the yellow
light of charger will slowly flash to indicate unusual charging status, this happens if you charge the battery pack under 0°C. If battery pack is in a low temperature (under-20°C)
its chemical solutions will be in solid state and resistance in charging will become too big for battery to be charged. If battery pack is in a high temperature(above 65°C), its
chemical solution will be in a vapor state that can make battery ineffective in a short time. Please note that charging temperature for battery is 10°C ~40°C, and discharging
temperature is betwen -20°C ~65°C. Please also note that ideal storage temperature is -20°C ~65°C!
2. Slide the battery to the battery charger. Slide the battery into the battery charger as shown below. Make sure it contacts the bottom of the battery charger. WARNING!
If the batteries are inserted in the reverse direction, not only recharging will become impossible, but it may also cause problems in the charger such as a deformed recharging
terminal.
3. Charging. When the battery is connected to the battery charger, charging will commence and the pilot lamp will light in red. If the pilot lamp flickers in red, pull out the
plug from the receptacle and check if the battery is properly mounted. When the battery is fully charged, the pilot lamp will light in green WARNING! If any of the following
occurs, unplug the charger from the power supply outlet and replace the battery pack: none of the indicators lights on or only the red indicator light is on even if the battery
pack is installed.
The indicators of the charger
RED: Charging
GREEN STEADY: Battery full
GREEN FLASH: High temperature pause and battery low volt
4. Disconnect battery charger from the receptacle. WARNING! Do not pull the plug out of the receptacle by pulling on the cord. Make sure to grasp the plug when removing
from receptacle to avoid damaging cord.
5. Remove the battery from the battery charger. Supporting the battery charger with hand, pull out the battery from the battery charger. WARNING! When the battery
charger has been continuously used, the battery charger will be heated, thus constituting the cause of the failures. Once the charging has been completed, give 15 minutes
rest until the next charging. If the battery is recharged when it is warm due to battery use or exposure to sunlight, the pilot lamp may light in green. The battery will not be
recharged. In such a case, let the battery cool before charging. When the pilot lamp flickers rapidly in red (at 0.2 – second intervals), check for and take out any foreign objects
in the charger’s battery installation hole. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.

2. Installing a socket align the plunger located in the square part of the shaft/anvil with the hole in the square socket. Check
that the plunger is fully engaged in the hole. When removing the socket, reverse the sequence.
3. Removing the socket. Please do the opposite point on the method of installing socket.
4. Confirm that the battery is mounted correctly.
5. Check the rotational direction the socket or bit rotates clockwise (viewed from the rear side) by pushing the R-side of the
push button. The L-side of the push button is pushed to turn the bit counterclockwise. (The L and R marks are engraved on
the body.) WARNING! The push button can not be switched while the impact wrench is turning. To switch the push button,
stop the impact wrench, then set the push button..
button
6. Switch operation. When the trigger switch is depressed, the tool rotates. When the trigger is released, the tool stops. The rotational speed can be controlled by varying the
amount that the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the trigger switch is pulled more. WARNING! A buzzing noise
is produced when the motor is about to rotate; this is only a noise, not a machine failure.
7. Tightening and loosening screws. Install the socket or bit that matches the screw, line up the bit in the grooves of the head of the screw, then tighten it.
Push the impact wrench just enough to keep the bit fitting the head of the screw. WARNING! Applying the impact wrench for too long tightens the screw too much and can
break it. Tightening a screw with the impact wrench at an angle to that screw can damage the head of the screw and the proper force will not be transmitted to the screw.
Tighten with this impact wrench lined up straight with the screw.
8. Tightening and loosening bolts. A square socket matching the bolt or nut must first be selected. Then mount the socket on the anvil, and grip the nut to be tightened with
the hex socket. Holding the wrench in line with the bolt, press the power switch to impact the nut for several seconds. If the nut is only loosely fitted to the bolt, the bolt
may turn wit the nut, therefore mistaking proper tightening. In this case, stop impact on the nut and hold the bolt head with a wrench before restarting impact, or manually
tighten the bolt and nut to prevent them slipping.
Maintenance and inspection
1. Checking the condition of the socket or bit: The bits should be checked regularly. If worn or broken bits can slip or decrease the efficiency of the motor and burn it out.
Replace worn bits with new ones. WARNING! Pull out battery before doing any inspection or maintenance.
2. Checking the condition of the socket A worn or deformed a square-holed socket will not give an adequate tightness to the fitting between the nut or anvil, consequently
resulting in loss of tightening torque. Pay attention to wear of a socket holes periodically, and replace with a new one if needed. WARNING! If you use a driver bit of which point
is worn or broken, it will be dangerous since it slips. So replace it with a new one.
3. Check the Screws. Loose screws are dangerous. Regularly inspect them and make sure they are tight. WARNING! Using this power tool with loosened screws or nut is extre-
mely dangerous.
Use
Check the work area to make sure that it is clear of debris and clutter. Clear the area of unnecessary personnel. Ensure that
lighting and ventilation is adequate.
1. Install the socket or bit. WARNING! Make sure it is not coming off, if the socket or bit is lightly pulled. Push forward the bit
chuck on one side. If the guide sleeve does not return to its original position, then the bit is not installed properly.

4. 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.
5. Inspecting the carbon brushes. The motor employs carbon brushes which are consumable parts. Since and excessively worn carbon brush can result in motor trouble, replace
the carbon brush with new ones when it becomes worn to or near the “wear limit”. In addition, always keep carbon brushes clean and ensure that they slide freely within the
brush holders.
6. Replacing carbon brushes. Take out the carbon brush by first removing the brush cap and then hooking the protrusion of the carbon brush with a flat head screw driver.
When installing the carbon brush, choose the direction so that the carbon brush agrees with the contact portion outside the brush
tube. Then push it in with a finger as illustrated in Lastly, install the brush cap. WARNING! Be absolutely sure to insert the nail of
the carbon brush into the contact portion outside the brush tube. Caution must be exercised since any error in this operation can
result in the deformed the carbon brush and may cause motor trouble at an early stage.
7. Check for Dust. Dust may be removed with a soft cloth or a cloth dampened with soapy water. Do not use bleach, chlorine,
gasoline or thinner, for they may damage the plastics.
8. Disposal of the exhausted battery. WARNING! Do not dispose of the exhausted battery. The battery must explode if it is incinerated. The product that you have purchased
contains a rechargeable battery. The battery is recyclable. At the end of its useful life, under various state and local laws, it may be illegal to dispose of this battery into the
