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
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.
