COMMON
8. Daily Inspection and Maintenance
•
Do not put fingers or foreign objects into the opening of the drive unit or reducer; otherwise, electric shock,
injury, fire, or damage to the equipment may occur.
•
The drive unit or reducer is very hot during operation. Touching the unit with bare hands; may cause
serious burns.
•
Do not touch the terminal when measuring insulation resistance; otherwise, electric shock may occur.
•
Do not operate the unit without a safety cover in place to shield rotating parts; otherwise, loose clothing may
become caught in the unit and cause serious injury.
•
Promptly identity and correct, according to instructions in this maintenance manual, any problems observed
during operation. Do not operate until abnormality is corrected.
•
Change lubricant according to the maintenance manual instructions. Be sure to use factory recommended lubricant.
•
Do not change lubricant during operation or immediately after stopping operation; otherwise, burns may occur.
•
Supply/discharge grease to/from the motor bearing according to the maintenance manual instructions. Avoid
contact with rotating parts; otherwise, injury may occur.
•
•
Do not operate damaged Paramax drive or reducers; otherwise, injury, fire or damage to the equipment may occur.
•
We do not assume any responsibility for damage or injury resulting from an unauthorized modification by the
customer.
•
Dispose drive unit, or reducer, and lubricant as general industrial waste.
•
When measuring the insulation resistance of an
explosion-proof type motor
, confirm that there is no gas,
steam or other explosive substance around the unit in order to prevent explosion or ignition.
•
Do not handle the unit when connected to the power source. Be sure to turn off the power; possible, electric shock
may occur.
•
Do not touch any rotating parts (output shaft, etc) during maintenance or inspection of the unit; loose clothing may
become caught in these rotating parts and cause serious injury or death.
•
•
•
Customers shall not disassemble or modify
explosion-proof type motors
; possible, explosion, ignition,
electric shock or damage to the equipment may occur.
•
The lead-in condition or an
explosion-proof type motors
shall conform to the facilities electrical codes,
extension regulations and explosion-proofing guide, as well as the maintenance manual; possible, explosion,
ignition, electric shock or damage to the equipment may occur.
DANGER
8-1) Daily Inspection
To ensure proper and continued optimum operation, use Table 16 to perform daily inspections.
Table 16 Daily Inspection
Inspection Item
Electric current
Noise
Vibration
Surface temperature
At rest
Oil or grease leakage
Foundation bolt
Chain and V-belt
When any problem is found during the daily inspection, take corrective measures listed in section 10. Troubleshooting (Page 29 and 30).
If the problem cannot be corrected, contact our nearest agent, distributor, or sales office.
When using
the trochoid
pump
Oil level
( Oil-lubricated
model )
CAUTION
Details of Inspection
Is the current below the rated current shown on the rating plate?
Is there abnormal sound ? Is there sudden change in sound?
Is there excessive vibration ? Does vibration change suddenly?
Does the surface temperature rise suddenly?
Does the oil level reach the top line of the oil gauge?
Is the function of oil signal or flow gauge normal?
When the function is abnormal, stop the unit and inspect it; otherwise, inadequate oil will
cause poor lubrication of reduction portion, broken pump and fill-up the oil pipe.
Does oil or grease leak from the gear section?
Are foundation bolts loose?
Are chain and V-belt loose?
Is the surface temperature abnormally high ( more than 90 C)?
The temperature rise during operation differs according to the models. When the
difference between the temperature of the gear surface and the ambient temperature is
approx. 80 C, there will be no problem if there is no fluctuation.
!
!
(Check it with a dipstick or oil gauge while the machine is shut down.)
Do not remove the inspection cover during operation; otherwise, hot splashing lubricant may cause burns.
When shutdown inspection is conducted on the state of the tooth surface, be sure to provide rotation stoppers for
the driving unit and driven unit; otherwise, loose clothing may become caught in the tooth engagement section
and cause serious injury.
Do not operate the unit with safety covers or other parts removed; loose clothing may become caught in these
rotating parts and cause serious injury.
