Troubleshooting - Worx WX178 Safety And Operating Manual

Drive Mode with Safe drive
•When driving a screw, the tool
will automatically stop as the
screw head becomes flush with
surface of workpiece. If a deeper
screw is desired, continue to
fully depress the Variable Speed
Switch (10). The tool will make
slow rotations to drive the screw
deeper.
• Once the desired depth is
reached, please release the
Variable Speed Switch (10).
NOTE:
1. If the tool stops sooner than
desired, release the Variable Speed
Switch (10) and press it again.
2. Safe drive function cannot
TM
be activated unless the variable
speed switch (10) has achieved the
maximum speed.
Drill Mode
Pulse Assist
WARNING: Do not work for
long periods with the Pulse
Assist activated as the motor can
be overheated.
NOTE: Pulse Assist is very
effective to prevent stripping
12
screws, removing stubborn screws
and to prevent the bit tip from
walking when drilling on smooth
surfaces. When the Pulse Assist is
activated, it can be switched with
the drill/drive mode.
• Make sure the Forward/Reverse
Rotation Switch (4) is pushed
to the left or right and the Pulse
Assist is selected.
• Press the Variable Speed Switch
(10), the tool will begin to rotate at
a controllable pace.
Variable Speed Switch
WARNING: Do not operate
for long periods at low
speed because excess heat will be
produced internally.

Using the LED light
To turn on the light, press the
Variable Speed Switch (10) and
make sure the Forward/Reverse
Rotation Switch (4) is on right or
left position. When you release the
Variable Speed Switch (10), the
light will go off after a moment.
The LED Light is also a battery
capacity indicator. It will flash
when power gets low.
The tool and battery pack are
equipped with a protection
system. When the LED Light is
quickly flashing, the system will
automatically cut power to the
tool to extend battery life. The tool
will automatically stop during
operation if the tool and/or battery
pack are placed under one of the
following conditions:
• Overloaded: The tool is
operated in a manner that causes
it to draw an abnormally high
current. In this situation, release
the Variable Speed Switch on
the tool and stop the application
that caused the tool to become
overloaded. Then pull the Variable
Speed Switch again to restart.
• Overheated: Under the
condition above, if the tool does
not start, the tool and Battery Pack
are overheated. Let the tool and
Battery Pack cool before pulling
the Variable Speed Switch again.
• Low battery voltage: The
remaining Battery capacity is too low
and the tool will not operate. Remove
and recharge the Battery Pack.

TROUBLESHOOTING

1. WHY DOES THE DRILL NOT TURN ON WHEN
YOU PRESS THE SWITCH?
The Forward/Reverse Rotation Switch, which is on
top of the trigger, is positioned in the lock function.
Unlock the Forward/Reverse Rotation Switch by
putting it into the required rotation position. Push the
trigger and the drill will start to rotate.
2. REASONS FOR DIFFERENT BATTERY PACK
WORKING TIMES
Charging time problems, and having not used a
Battery Pack for a prolonged time will reduce the
Battery Pack working time. This can be corrected after
several charge and discharge operations by charging
& working with your drill. Heavy working conditions
such as large screws into hard wood will use up
the Battery Pack energy faster than lighter working
conditions. Do not re-charge your Battery Pack below
