Electrical Safety; Assembly And Adjustment - DeWalt DCH363 Original Instructions Manual

E N G L I S H
ACTIVE VIBRATION CONTROL
The active vibration control neutralises rebound
vibration from the hammer mechanism. Lowering
hand and arm vibration, it allows more comfortable
use for longer periods of time and extends the life of
the unit. In operation, a spring loaded mechanism
counterbalances the vibration forces. This can be
sensed by the cushioning effect when pressure is
applied to the tool. Make sure the spring is engaged
but not too firmly. The mechanism should be allowed
to "float."

Electrical Safety

The electric motor has been designed for one voltage
only. Always check that the battery pack voltage
corresponds to the voltage on the rating plate.
Also make sure that the voltage of your charger
corresponds to that of your mains.
Your D WALT charger is double insulated
E
in accordance with EN 60335; therefore no
earth wire is required.
If the supply cord is damaged, it must be replaced
by a specially prepared cord available through the
D WALT service organization.

Mains Plug Replacement
(U.K. & Ireland Only)
If a new mains plug needs to be fitted:
• Safely dispose of the old plug.
• Connect the brown lead to the live terminal in the
plug.
• Connect the blue lead to the neutral terminal.
WARNING: No connection is to be made
to the earth terminal.
Follow the fitting instructions supplied with good
quality plugs. Recommended fuse: 3 A.
Using an Extension Cable
An extension cord should not be used unless
absolutely necessary. Use an approved extension
cable suitable for the power input of your charger
(see technical data). The minimum conductor size is
1 mm 2 ; the maximum length is 30 m.
When using a cable reel, always unwind the cable
completely.

ASSEMBLY AND ADJUSTMENT

WARNING: Prior to assembly and
adjustment, always remove the
battery pack. Always switch off the
12
tool before inserting or removing the
battery pack.
WARNING: Use only D
packs and chargers.
Fitting and Removing the Battery
Pack (fi g. A)
• To fit the battery pack (11), line it up with the
receptacle on the tool. Slide the battery pack into
the receptacle and push until the battery snaps
into place.
• To remove the battery pack, push the release
button (12) while at the same time pulling the
battery pack out of the receptacle.
FUEL GAUGE BATTERY PACKS (FIG. A)
Some D WALT battery packs include a fuel gauge
E
which consists of three green LED lights that indicate
the level of charge remaining in the battery pack.
To actuate the fuel gauge, press and hold the fuel
gauge button (21). A combination of the three green
LED lights will illuminate designating the level of
charge left. When the level of charge in the battery
is below the usable limit, the fuel gauge will not
illuminate and the battery will need to be recharged.
NOTE: The fuel gauge is only an indication of the
charge left on the battery pack. It does not indicate
tool functionality and is subject to variation based
on product components, temperature and end-user
application.
Selecting the Operating Mode (fi g. C)
The tool can be used in the following operating
modes:
Rotary drilling: for screwdriving and for
drilling into steel, wood and plastics
Hammer drilling: for concrete and
masonry drilling
Hammering only: for light chipping
• To select the operating mode, press the safety
lock (4) and rotate the mode selector switch (3)
until it points to the symbol of the required mode.
• Release the safety lock and check that the mode
selector switch is locked in place.
WARNING: Do not select the operating
mode when the tool is running.
