CAUTION
• Check the rotation direction before connecting the product to
the driven machine. Connecting the product to an incorrect rota-
tion direction may result in personal injury or equipment dam-
age.
• When the product is to run on its own without being connected
to other devices, remove the key from the output shaft in ad-
vance. Otherwise, the key may fly off the shaft and cause per-
sonal injury.
• Install a cover or other appropriate protection over the rotating
parts to prevent human contact. otherwise, injury may result.
• When connecting the product to a load device, check alignment,
belt tension and pulley parallelism for correct connection. In the
case of direct coupling, carefully verify coupling accuracy. In the
case of belt connection, correctly adjust belt tension. Before run-
ning the product, check that all the pulley/coupling tightening
bolts are tight. Running the product with loose coupling may
result in equipment damage due to fragments ying o the unit.

[8] Daily Inspection and Maintenance
8-2 Maintenance of Main Unit
• Oil seals have a life, and after long-term use there may be a de-
crease in the seal effect due to natural deterioration and wear.
Although the seal life greatly diers depending on the operating
conditions and surrounding environment of the reducer, it is rec-
ommended that the seal be replaced every 1 to 3 years.
If the sliding surface of the oil seal becomes worn or rusted, replace
the seal with a new one.
The unit’s sliding surfaces are carbon steel. Any exposed part of the
oil seal sliding surface must periodically receive rust prevention
treatment such as rustproong oil application so that rusting will
not progress on the sliding surface.
8-3 Backlash
The product has been assembled with a preconditioned backlash
A complete backlash reconditioning would be necessary if the
product is disassembled. Do not disassemble the product.
