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 efficient, 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 efficiency of the blower.

Frequently empty the dust bag to ensure maximum

dust collecting efficiency.

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

brushes with new ones having the same carbon brush

No. shown in the figure when it becomes worn to or

near the “wear limit”. In addition, always keep carbon

brushes clean and ensue that they slide freely within

the brush holders.

3. Replacing carbon brushes

Disassemble the brush caps with a slotted-head

screwdriver. The carbon brushes 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.
