MOUNTING AND DISMOUNTING THE NOZZLE
AND DUST BAG
1. Mounting the NozzIe
Insert the pin located outside the nozzle into the notch
provided on the blast port, and fully turn the nozzle in
the direction indicated by the arrow in Fig. 1.
To dismount the nozzle.,folIow the above procedures in
reverse.
2. When using the Blower for dust collection
(1) Mounting the Dust Bag
Mount the dust bag on the blast port, following the
same procedure described above for mounting of
the nozzle (Fig. 2).
(2) Mounting the nozzle
Insert the pin located on the outside of the nozzle
into the notch provided on the suction port, and
fully turn the nozzle in the direction indicated by the
arrow in Fig. 3.
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.
