1, regular inspection of the North Ben V3 accessories wiper blade. When the wiper blade is badly worn or soiled, it should be replaced or cleaned in time, otherwise it will reduce the work efficiency of the wiper and influence the sight of the driver. Clean the wiper blade for a while and wipe the dirt off the wiper blade with cotton detergent dipped in alcohol. Scraping pieces can not be cleaned and soaked with gasoline, or scraping will deform and affect their work.
2, check the North V3 fittings wiper work, should first use water wetting windshield, otherwise it will scratch the glass, and because of the friction resistance of wiper blade, may damage the wiper or burn the motor. Open the wiper switch, the motor should pay attention to abnormal sound, especially when the wiper motor “humming” sound without rotation, the mechanical transmission part has rust or stuck, should immediately turn off the North Pennines heavy truck accessories wiper switch, to prevent burning motor.
3. Switch off the wiper after use. The wiper blade should return to the lower side of the windshield to stop. If the stop position is wrong, it should be adjusted. When adjusting, the cover of the automatic stop can be turned, the clockwise rotation stop position is shortened, and the stop position is extended by anticlockwise rotation.
4, winter wiper blade, if the frozen or snow stuck, should close the switch immediately, remove the ice and snow before it can continue to use, otherwise they will be scraping resistance is too large to burn out the motor.
5, do not arbitrarily remove the motor. If the motor does not need to be removed due to a fault, do not let the motor fall or collide. Because the North V3 parts wiper motor mostly use permanent magnet DC motor, its magnetic poles are more ceramic materials, easily damaged by impact.
6, wiper motor mostly closed type, not optional disassembly. When you have to remove, keep the inside clean and do not let the dirt such as iron filings fall into it; when assembling, add a little lubricating oil to the felt of the oil bearing, and replace or supplement the grease in the reducer.
