CLEANING - Continued
Cleaning with compressed air can cause flying particles. When using compressed air, wear
protective glasses and use clean, low pressure air, less than 30 psi (208 kPa). Failure to comply
can cause eye injury to personnel.
2. Compressed air may be used to clean dirt from areas where a cloth will not reach. Use low pressure
compressed air, 30 psi maximum.
3. Dry dust and dirt may be removed by vacuum cleaning.
4. When completely disassembled, most generator components (except electronic parts) may be steam cleaned.
5. Make sure all components are completely dry before assembly.

Wear heat resistant gloves and avoid contacting hot metal surfaces with your hands after
generator drive hub has been heated. Wear additional protective clothing as required. Failure to
comply can cause injury to personnel.
6. Heat new drive hub (Figure 1, Item 23) in oven to 500-600 degrees F (260-316 degrees C). Using suitable heat
resistant gloves, slide drive hub (Figure 1, Item 23) on shaft until it seats against shaft shoulder. Allow drive
