Break
Do not block the air vents.
5.3 Cooling Ventilator
In case of the motor temperature is below 40°C, the cooling ventilator
operates only when the trigger is pulled. When the motor temperature
exceeds 40°C, the ventilator continues to operate until the motor temperature
drops below 40°C. After the ventilator stops its operation,
pull the trigger again so that the ventilator operates
with the above logic.
Do not block the air vents when the tool is in use.
Insufficient ventilation may result in heat or smoke.
5.4 Overheating Protection
Overheating protection functions to disable the tool
when the motor heats up due to exceeding duty cycle.
OK/NOK Judgement LED tube turns red and disables the tool
until the red LED turns off.
Once the red LED blinks, do not use the tool for 30 minutes at least until the motor temperature has
cooled down. Do not detach and re-attach the battery or replace the battery with another one while
the red LED blinks.
This resets the heating protection even with the overheating motor.
Guidance of Suitable Applications for UBX-AF series
Example : UBX-AF700Z
Working condition : (the same as the durability test condition, See P9. Operating Cycle per Full-Charge)
Bolt Size --- M12
Fastening Time per Fastener --- approx. 0.5 sec.
UBX-AF700Z will be able to fasten 9 fasteners per minute under the above working condition.
Mathematical Expression ------ 0.5 sec./fastener
×
9 fasteners/min. = 4.5 sec./min.
With UBX-AF700Z, overheating protection will not function as long as the tool tightens M12 fasteners for
total 4.5 sec. per minute, see below.
Softer joints (i.e. longer fastening time per fastener) will require less aggressive fastening cycles.
5.5 After Daily Use
When the working day is over, detach the battery from the tool to avoid unexpected
operation nor electric shock.
Cover the battery pack for dust / rubbish adhesion prevention.
