SELECTION OF BLADES
Accessory blades
To ensure maximum operating efficiency and results, it is very important to select the
appropriate blade best suited to the type and thickness of the material to be cut. Three
types of blades are provided as standard accessories. The blade number is engraved in
the vicinity of the mounting portion of each blade. Select appropriate blades by referring
to Table 1 (page 18).
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 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:
3. Inspecting the carbon brushes (Fig. 15)
The motor employs carbon brushes which are consumable parts. Replace the carbon
brushes with new ones when it becomes worn to its wear limit. When an auto-stop carbon
brush is equipped, the motor will stop automatically. At that time, replace both carbon
brushes with new ones. Always keep carabon brushes clean and ensure that they slide
freely within the brush holders.
CAUTION
Using this jig saw with a carbon brush
which is worn in excess of the wear limit
will damage the motor
NOTE: Use HITACHI carbon brush No. 46
indicated in Fig. 15.

Be sure to switch power OFF and disconnect the plug from the receptacle
