SAFETY PRECAUTIONS:
When the safety precautions are followed,
the DXR8-E will provide years of enjoyment.
Use care and good sense at all times when
operating this radio controlled vehicle.
Failure to use this vehicle in a safe, sensible
manner can result in injury or damage to
property. You and you alone must insure
that the instructions are carefully followed
and all safety precautions are obeyed.
➤
Do not operate the DXR8-E near people.
Spectators should be behind the driver or
at a safe distance away from the vehicle.
➤
Make sure to read the instructions with the
battery and charger before charging.
➤
Do not leave any charger unattended
during charging. If the battery or charger
become hot at any time, disconnect the
battery from the charger immediately!
Failure to do so may cause permanent
damage to the charger and battery and
may cause bodily harm.
➤
When charging LiPo battery packs, always
use a charge bag such as GPMP0751.
➤
Always turn on the transmitter before
turning on the electronic speed control.
HELPFUL HINTS:
➤
Avoid working over a deep pile carpet. If
you drop a small part or screw, it may be
difficult to find.
➤
Place a mat or towel over your work area.
This will prevent parts from rolling off and
will protect the work surface.
➤
Avoid running the vehicle in cold weather.
The plastic and metal parts can become
brittle at low temperatures. In addition,
grease and oil become thick, causing
premature wear and poor performance.
