DRIVE MOTOR MAINTENANCE

1.Visually inspect the motor daily before use for defective or missing parts, and have repairs made before use.

2.Inspect brushes frequently and replace when they become worn to a length of 3/8". See Length A in Figure 8.

Figure 8. Brush Length

3.Keep air inlet and air exit louvers clean and free of concrete and debris. Failure to do so will result in rapid motor overheating and parts failure.

4.Clean air filter as needed. If unit is used in high dust areas, filter will have to be cleaned more often.

5.Use a screw driver to tighten brush caps. DO NOT OVERTIGHTEN. The brush cap must be tight enough that the brush holder does not move.'

1.If installed, remove head assembly and shaft coupling.

2.Remove slotted spring using hammer and punch of appropriate size.

3.Once the pin is removed, the quick-disconnect knob, compression spring, and lock pin can easily be removed.

4.Using a bench vice and wrench, remove coupler from flexshaft as shown in Figure 10. Please note threads are right-handedon this side of the flexshaft (drive motor end).

5.Heat should be applied to the threads to break down the anaerobic sealant. Applying heat will help prevent possible damage to threads.

6.Next, using a wrench and bench vise if necessary, remove flexible shaft from vibrator head as shown in Figure 10. Please note threads are left-handedon this side of the flexshaft (vibrator end).

7.Pull the wire core out from casing. Using a clean soft cloth, wipe the grease off as the wire core is pulled

from the casing. Wipe clean.
