1.Product Check
(1) Check that the model number, output, speed, etc. you specified are written on the nameplate.
(2) Check that the product is not damaged during transportation.
(3) Check the screws and bolts for looseness.
2.Operation Conditions and Ambient Conditions
(1) Do not place any object inflammable near the geared motor. Failure to observe this warning may case fire or explode.
(2) Do not use the geared motor as elevator for human transport. Use of a geared motor for such a purpose is prohibited by the Building Standard
Law.
(3) If the equipment is to be used with an elevator, be sure to burnish with a safety device to prevent the elevator from accidental falling. Failure
to observe this warning may cause physical injury and damage to the equipment.
(4) Do not rotate the geared motor at a high speed from the load side. The motor may be exploded.
(5) Be careful when a small power low gear ratio model raises operation frequency to 60Hz or more, rotation speed may not rise because of the
influence of a machine loss.( Example: When 120Hz operation is performed by 0.1kW gear ratio 1/5,1/7.5 etc.)
(6) Don't use an inside-of-a-house type on a moist place and the outdoors. Generating of rust and the fall of insulation resistance may be caused by
dew condensation or permeation of water. Use an outdoor type, when you use under such environment.
(7) Keep in mind that it may result in allophone generating or bearing breakage by electric corrosion if career frequency is highly set up by inverter
operation.
3.Installation and Adjustment
(1) If the geared motor is equipped with a hoisting accessory, be sure to use the hoisting accessory to lift and transfer a load.
(2) If the geared motor malfunctions, the grease may leak from the motor. To protect the environment from the grease, place an oil pan at the
leak point.
(3) Be sure to attach safety covers to the belts, chains, gears, etc.
(4) The grease lubrication method is adopted for all the motor models. The grease lubrication type geared motors can be installed in any direction.
(The grease is full at the time of factory shipment.)
(5) Install the motor at an appropriate place that ensures low humidity and little dust. Check that the ambient temperature is between –15
and +40 , and the relative humidity is 90% or less. Check that the motor cannot be frozen at the installation place. In addition, check the
motor cooling condition of the installation place. The motor should not be extremely heated.
(6) Install the motor on a rigid and thermal conductive base using bolts having strength of 8.8 or above. Adjust the flatness of the installation
surface to 0.2mm or less. Moreover, put in an attachment pitch into the tolerance shown in Table 2 in the GM-SSY type.
(7) To mount a flange mounting (face mounting) type or foot mounting type geared motor, be sure to use the bolts of the corresponding size as
shown in Table 1.
(8) The installation of GM-SSY type must use the size shown in Table 2 respectively bolt. Please use a special washer of the attachment at the
flange installation.
