MAINTENANCE AND INSPECTION

1. Inspecting the depressed center wheel

Ensure that the depressed center wheel is free of

cracks and surface defects.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure

that they are properly tightened. Should any of the

screws be loose, retighten them immediately. Failure

to do so could result in serious hazard.

3. Inspecting the carbon brushes (Fig. 5)

The motor employs carbon brushes which are

consumable parts. Since an excessively worn carbon

brush can result in motor trouble, replace the carbon

brushes with new ones having the same carbon

brush No. shown in the figure when it becomes

worn to or near the “wear limit”. In addition, always

keep carbon brushes clean and ensue that they

slide freely within the brush holders.

4. Replacing carbon brushes (Fig. 6)
