Maintenance And Inspection - Hitachi rb 40sa Handling Instructions Manual

English
HOW TO USE THE BLOWER
1. By pulling the trigger and pushing the stopper, the
switch will remain in the ON position even when the
trigger is released, promoting effi cient, continuous
operation. By pulling the trigger again, the stopper
is disengaged and the switch is turned OFF when the
trigger is released.
2. On the RB40VA, the pulling force on the switch
changes the amount of blow force. The maximum
amount of blow force can be adjusted with the speed
control dial (Fig. 4).
3. An excessively large volume of dust in the dust
bag will reduce the dust collecting effi ciency of the
blower. Frequently empty the dust bag to ensure
maximum dust collecting effi ciency.

MAINTENANCE AND INSPECTION

1. 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.
2. 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
brush with a new one having the same carbon brush
No. shown in the fi gure 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.
3. Replacing carbon brushes
Disassemble the brush cap with a screwdriver. The
carbon brush can then be easily removed.
4. 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.
