Battery packs should be tuned up after every 10th charge/ discharge
cycle or whenever the pack no longer delivers the same amount of
work. To use the automatic tune-up mode, simply place the battery
pack in the charger and leave it for at least eight hours. The charger
will cycle through the following modes.
1. The red light will blink continuously indicating that the 1-hour
charge cycle has started.
2. When the 1-hour charge cycle is complete, the light will stay on
continuously and will no longer blink. This indicates that the pack
is fully charged and can be used at this time.
3. Whenever the pack is left in the charger after the initial 1-hour
charge, the charger will begin the Automatic Tune-Up™ Mode.
This mode continues up to 8 hours or until the individual cells in
the battery pack are equalized. The battery pack is ready for use
and can be removed at any time during the Tune-Up™ Mode.
4. Once the Automatic Tune-Up™ Mode is complete the charger
will transition to a maintenance charge; no indicator light shows
the completion of the Automatic Tune-Up™ Mode.
Using the Manual Tune-Up™ Mode

hours to complete. Battery packs should be tuned up weekly or after
10 to 20 charge/discharge cycles or whenever the pack no longer
delivers the same amount of work.
1. To tune up your battery pack, place the battery in the charger as
usual. The red light will blink continuously indicating that the
charge cycle has started.
2. Press the Tune-Up™ Mode button any time after the charge cycle
has started. The red light will stop blinking momentarily, blink
quickly 3 times, and then resume blinking continuously. The
charger is now tuning up the cells in your battery.
3. When the Tune-Up™ mode cycle is complete, the light will stay on
continuously. The pack is fully charged and may be used at this
time or left in the charger.
4. If you select Tune-Up™ Mode and then change your mind,
remove the battery from the charger. After 5 seconds, insert the
battery into the charger. The normal charge cycle will begin.
Side Handle (Fig. 3)
A side handle (A) is supplied with this hammer. It clamps to the front of
the gear case as shown and can be rotated 360˚ to permit right or left
hand use.
CAUTION: Always use the side handle supplied with the tool.
Keep a firm grip on the tool at all times. Do not attempt to operate this
tool without holding it with both hands. Operating this tool with one
hand will result in loss of control. Breaking through or encountering
hard materials such as re-bar may be be hazardous as well.
Variable Speed Switch (Fig. 3-B)
To turn the tool on, squeeze the trigger switch. To turn the tool off,
release the trigger switch. Your tool is equipped with a brake. The
chuck will stop as soon as the trigger switch is fully released.
The variable speed switch enables you to select the best speed for a
particular application. The farther you squeeze the trigger, the faster
the tool will operate. Use lower speeds for starting holes without a
center punch, drilling in metals or plastics, driving screws and drilling
ceramics. For maximum tool life, use variable speed only for starting
holes or fasteners.
