operation
Cautions for installing reducer:
1.Please check if the rotated direction of output shaft is correct before assemble the reducer with mechanical equipment.
2.Before the reducer is assembled with the original motor and equipment, size deviation of each shaft diameter, bore diameter, key and key slot should be inspected to avoid affecting performance of reducer due to tight or loose assembly.
3.The reducer must be tightly mounted on the mechanical equipment to prevent from looseness and vibration.
4.Please avoid making the reducer exposed under burning sun and bad condition.
5.If the reducer have been stored for 4-6 months, please check if the oil seal is soaked by lubrication oil. Maybe the oil seal lip stick to the shaft even it lose elasticity. Since the proper elasticity is a essential working condition of oil seal, so change the oil seal.
6.All the rubber parts and air vent must not be stained with paint.
7.The mating part of shaft should be coated with lubrication oil to avoid struck or oxidation when matching with the reducer hollow shaft.
8.Please inspect the oil level when use the reducer.
9.Do not start the reducer with full load when use a new reducer, please increase the load gradually.
10.When use reducer which motor can direct connect with, if the motor weight is higher, a supporting unit should be set up.
11.Please make sure the motor fan is under a good ventilated condition in case the radiation efficiency is influenced.
12.The standard working temperature of reducer is range from -5℃ to 40℃, please get contact with our technical staff if your working temperature is beyond the range.
