Items to Check

Noises

The Brushless Motor Spindle housing temperature 
during the break-in process should not exceed 
20 degrees C (36 degrees F) above ambient 
temperature. Should the Brushless Motor Spindle 
exceed this limit, rest the Brushless Motor Spindle 
for at least 20 minutes and re-start the break 
in procedure from the beginning. If the housing 
temperature rises again and exceeds 20 degrees C 
(36 degrees F) above ambient temperature, check 
the Brushless Motor Spindle for proper installation.

The Brushless Motor 
Spindle housing 
temperature during 
the break-in process 
should not exceed 
20 degrees C (36 
degrees F) above 
ambient temperature.

During transportation, storage or installation, the grease inside the bearings will settle. If the Brushless Motor 
Spindle is suddenly run at high-speed, the grease will be ejected from the bearings, causing excessive heat that 
will cause bearing damage.
After installation, repair, initial operation, or long periods of non operation, please follow the break-in procedure 
detailed in Table. 2. 

Table. 2

GREASE INJECTION

12.

Be sure to use our specied grease. The other type grease may cause damage to Brushless Motor 
Spindle.

When the thread on the side of the Brushless Motor Spindle is removed, need to stop the air supply.
Failure to stop the air ow will cause grease to spray out of the grease inlet.

 

 CAUTION

To extend the durability of the reduction gear, inject grease at every 70 - 100 hours in the manner described below. 
Grease injection prevents the friction of the parts assembled inside as well as heat generation. It also prevents the 
degradation of grease inside.
Periodic grease injection is an important part of routine maintenance.

12 - 1  Grease Injection

Mount the Grease Nipple on the top of the 
provided Grease Dispenser. And attach the 
Grease Nipple on the topped hole removed the 
thread in the step.

Turn OFF the power switch of the 
CONTROLLER and stop the air supply.  

Remove the Grease Inlet Screw on the 
Brushless Motor Spindle with a screw driver 
(Fig. 20).
