D WALT repair agent. Whilst charging, the charger
E
and the battery pack may become warm to touch.
This is a normal condition and does not indicate a
problem.
Do not charge the battery pack at
ambient temperatures < 4 °C or > 40 °C.
Recommended charging temperature:
approx. 24 °C.
• To charge the battery pack (14), insert it into the
charger (16) as shown and plug in the charger.
Be sure that the battery pack is fully seated in the
charger. The red charging indicator (17) will blink.
After approx. 1 hour, it will stop blinking and
remain on. The battery pack is now fully charged.
The battery pack can be removed at any time or
left in the connected charger for a longer period
of time (with a maximum of 14 days).
Inserting and removing the battery pack

buttons (15) simultaneously and pull the pack out
of the grip.
Battery cap (fig. B)
A protective cap is supplied to cover the contacts of
a detached battery pack. Without the protective cap
in place, loose metal objects could short circuit the
contacts, causing a fire hazard and damaging the
battery pack.
• Take off the protective cap (18) before placing
the battery pack (14) in the charger or tool.
• Place the protective cap over the contacts
immediately after removing the battery pack from
the charger or tool.

Automatic refresh
The automatic refresh mode will
equalize or balance the individual
cells in the battery pack at its peak
capacity. Battery packs should be
refreshed overnight after every 10th
charge/discharge cycle or whenever
the pack no longer delivers the same
amount of work.
• To refresh your battery pack, place the battery in
the charger as usual. The red light will blink
continuously indicating that the charge cycle has
started.
• When the 1-hour charge cycle has completed,
the light will stay on continuously and will no
longer blink. The pack is fully charged and can
be used at this time.
• If the pack is left in the charger after the initial
1-hour charge, the charger will automatically
initiate the refresh mode. This mode will continue
up to 8 hours, but the battery pack can be
removed at any time during the refresh mode.
Hot/Cold Pack Delay
When the charger detects a battery that is too hot or
too cold, it automatically starts a Hot/Cold Pack
Delay, suspending charging until the battery has
reached an appropriate temperature. The charger
then automatically switches to the pack charging
mode. This feature ensures maximum battery life.
The red indicator blinks long, then short while in the
Hot/Cold Pack Delay mode.

• Loosen the depth adjustment knob (13).
• Move the shoe (6) to obtain the correct depth of

The bevel angle can be adjusted between 0° and 50°.
• Loosen the bevel adjustment knob (11).
