6. Whenever installing a Brushless Motor to a fixed metal base, ensure that the fixed metal base is grounded in order to avoid risk of an electric shock.

CAUTION

1. Do not drop or hit this Brushless Motor, as shock can damage to the internal components.
2. When cleaning a Brushless Motor, stop the Brushless Motor and remove debris with a soft brush or a cloth. Do not blow air into the Brushless Motor with compressed air as foreign particles or cutting debris may get into the ball bearing.
3. Select suitable products or tools for all applications. Do not exceed the capabilities of the Brushless Motor or tools.
4. Do not stop the supplied cooling air to the Brushless Motor during operation of the machine. Removing the air pressure from the Brushless Motor causes a loss of purging, allowing the Brushless Motor to ingest coolant and debris. This will cause damage to the Brushless Motor.
5. Stop working immediately when abnormal rotation or unusual vibration are observed. Immediately, please check the content of section ” 9. TROUBLESHOOTING “.
6. Always check if the connection hose and supply air hose for damaged before and after operating.
7. After installation, repair, initial operation, or long periods of non operation, please carry out break in as follow. Start rotating slowly and over a short period of 15 – 20 minutes, increase speed gradually until Maximum Allowable Motor Rotation Speed.

CONNECTION OF THE MOTOR TO THE SPINDLE

CAUTION

• Make sure your hands and all interlocking parts of the spindle and the Brushless Motor are clean before connecting the Brushless Motor to the spindle. This is critical in preventing contaminants from entering the Brushless Motor or the spindle.
• The new drive clutch is (+) configuration. The (+) drive spindles were designed to be used with (+) drive Brushless Motors and speed reducers (Fig. 8).

Align the thread on the front end of the Brushless Motor and the rear of the spindle, and turn the spindle clockwise. If the drive shaft of the Brushless Motor does not engage properly to the drive dog on the spindle, it may only turn approximately two threads before stopping. DO NOT FORCE THEM TOGETHER. Loosen the spindle from the Brushless Motor, rotate the spindle shaft by hand then re-try. The drive shaft and the drive dog must be fully engaged. When fully engaged, secure the spindle and Brushless Motor using the provided 22mm wrench (Fig. 9).
