MAINTENANCE AND INSPECTION
WARNING:
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 screws
Regularly inspect all screws and ensure that they are properly tightened. Should any of
the screws be loosened, retighten them immediately.
WARNING:
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 not become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes (Fig. 33)
The motor employs carbon brushes which are
consumable parts. Since and excessively worn
carbon brush can result in motor trouble, replace
the carbon brush with new ones when it becomes
worn to or near the "wear limit". In addition, always
keep carbon brushes clean and ensure that they slide
freely within the brush holders.
NOTE:
When replacing the carbon brush with a new one,
be sure to use the Hitachi Carbon Brush Code No.
999058.
5. Replacing carbon brushes
Take out the carbon brush by first removing the
brush cap and then hooking the protrusion of the
carbon brush with a slotted-head screw driver, etc.,
as shown in Fig. 34, Fig. 35.
When installing the carbon brush, choose the
direction so that the nail of the carbon brush (Fig.
34) agrees with the contact portion outside the brush
tube (Fig. 36). Then push it in with a finger.
Lastly, install the brush cap.
Be sure to turned off the switch and remove the battery before
maintenance and inspection.
Using this Cordless Reciprocating Saw with loosened screws is
extremely dangerous.
