8. Matters to be paid attention to when using motor

8-1 Please lay the motors carefully in transportation to avoid any serious damage to the motor body or its electric function because of collision.

8-2 Please use and storage motors according to N0.2 item (Operating Conditions) in specification, or else motor characteristics would be affected.

8-3 Make arrangement to limit the storage period to 6 months or less. Condensation of atmosphere must be avoided in motor usage or opening the packaging of the motor.

8-4 For proper operation. storage and operating environment must not contain corrosive gases. For example H2S. SO2. NO2. CL2. etc. In addition storage environment must not have materials that emit corrosive gases especially from silicon. cyanic. formalin and phenol group. In the mechanism or the set. existence of corrosive gases may cause no rotation in motor.

8-5 Please don't stall the shaft for a long time after powering, and not to touch the weight when motor is rotating.

8-6 There should be no sundries (such as grain, fiber, hair, small tape, glue etc.) in the shaft end play.
