Maintenance and Inspection

Hitachi CR 13VA instruction manual Maintenance and Inspection

English

WARNING: Be sure to switch power OFF and disconnect the plug from the receptacle during maintenance and inspection.

1.Inspecting the blade

Continued use of a dull or damaged blade will result in reduced cutting efficiency and may cause overloading of the motor. Replace the blade with a new one as soon as excessive abrasion is noted.

2.Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loosened, retighten them immediately.

WARNING: Using this reciprocating saw with loosen screws is extremely dangerous.

3.Maintenance of the motor

The motor unit winding is the very “heart“ of the power tool. Exercise due care to ensure the winding does noto become damaged and/or wet with oil or water.

4.Inspecting the carbon brushes (Fig. 28)

The Motor employs carbon brushes which are consumable parts. When they become worn to or near the “wear limit”, it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones which have the same carbon brush Numbers shown in the figure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.
