Unpacking
Due to modern mass production techniques, it is unlikely that your GMC Power Tool is faulty or that a part is missing. If you find anything wrong, do not operate the tool until the parts have been replaced or the fault has been rectified. Failure to do so could result in serious personal injury.
Important information – Product care
This drill driver uses Lithium Iron Battery Cells. Care MUST be taken to ensure both the safety and life of the pack is maintained. Ensure you have read all of the safety notes in the previous pages before using the drill/driver.
Safety devices and circuitry for this tool are located in the battery pack of this tool. The battery pack is a vital component, not just for the power source, but also for the full safety control for both the charging and also the tool operation. Treat the battery pack with care and within the guidelines of this manual. If the pack does become immersed in water or any fluids, or is subject to a sever drop etc, or it does not operate within the guidelines of this manual, immediately STOP using the battery pack and have it checked.
During operation avoid overloading the drill driver. If the drill driver is overloaded it will automatically STOP. Overloading may occur for a number of reasons including when the drill driver is pushed too hard or when using a drill bit or attachment greater than what is specified. If you do overload the drill driver during operation refer to the “Overload” section in this manual.
Note: When the battery of the drill is at the lower end of the charge, the drill is more susceptible to the overload condition.
As mentioned above the battery pack is an integral component of this tool and it is fitted with thermal safety devices. Running the drill at close to maximum load, or continual resetting of the overload will cause the battery pack to over heat. When a preset cell temperature is detected, the battery pack will automatically STOP operating and will not restart until the battery pack has cooled to a safe level.
In this condition, DO NOT force cool the pack by placing in a freezer or similar device. Refer to the “Overload” section in this manual.
Another feature of the drill/battery pack is the low voltage cut out feature. This feature operates when the voltage drops below a pre set value. When this occurs the tool will automatically stop operating. To correct the situation you need to either insert another charged battery into the drill or recharge the existing battery, and then proceed with the drilling/driving application.
Note: Attempting to restart the tool in this condition without either recharging the battery or installing a battery with charge will lead to drill restarting and then stopping again after only a few seconds of operation.
These safety devices have been fitted for the safety, reliability and life of the tool.
Fitting and removing the battery pack
To remove the battery pack from the drill firmly press the battery release button (7) at the front of the battery pack, and pull the battery backward out of the tool.
To install the battery pack into the base of the drill, you need to align the location rib on the battery pack with the engagement groove located on the base of the drill. Ensure the battery pack locks into position, you will hear a “click”.
