Tonka DUMP TRUCK, Owner'S Manual

25

Problem

Short run time  

(Less than 15 minutes  

per charge)

Possible Cause

Tripped thermal fuse 

Undercharged battery

Overcharged battery

Battery is old and will not 

accept full charge

Tripped thermal fuse

Solution

The built-in thermal fuse may “trip” and shut 

down operation of the vehicle if the vehicle 

is overloaded or the driving conditions 

too severe. Once a fuse has “tripped”, set 

the power switch to the “OFF” position, 

release the foot pedal, and wait 2 minutes 

before operating the vehicle again. To avoid 

repeated automatic shutdowns, do not 

overload the vehicle by exceeding the 130

Ibs maximum weight capacity or by towing 

anything behind the vehicle. Do not drive 

up hills or run into fixed objects, which can 

cause the wheels to stop spinning while 

power is still being supplied to the motors.

Charge the battery. A new battery should 

have been charged for at least 18 hours 

before using the vehicle for the first time. 

After first-time use, recharge the battery 

for at least 12 hours after each use. Never 

charge the battery longer than 30 hours.

Check all wires and connectors. Make sure 

the battery connector is tightly plugged into 

the control module connector, and that the 

charger is plugged into the wall.

Make sure that there is power flow to the 

wall outlet.

Do not charge the battery longer than 30 

hours. If you suspect that your battery 

is damaged as a result of overcharging, 

change with one new original 12 Volt (10 

Amp/Hr.) battery with built-in thermal fuse. 

Do not use non-original substitute parts.

Even with proper care, a rechargeable 

battery does not last forever. Average battery 

life is 1 to 3 years depending on vehicle use 

and use conditions. Replace only with an

original 12 Volt (10 Amp/Hr.) battery with 

built-in thermal fuse. Do not use non-original 

substitute parts.
