T ECHNICAL INFORMATION
Models No. 9045N
New Tool
Description MAKITA Finishing sander
CONCEPT AND MAIN APPLICATIONS
The model 9045N has been developed as the new
model of the current type of 9045. Unlike the
conventional type, the dust collecting unit is
installed and the machine vibration has been
minimized to extremely improve the working efficiency.

Features and benefits
(1) High working efficiency and beautiful finishing
The RPM is not changed from conventional type of #9045, but the decentering amount has been increased from
0.75 to 1.2 mm to improve the grinding efficiency.(See the 5. Capacity for comparison of efficiency.)
(2) By the belt driving the torque of output shaft has been increased
Since the pad rotation is directly connected with the motor in the conventional type, the motor rotation is
suppressed at low and the torque is decreased, and if the machine body is pressed, the rotation is extremely
lowered and it may make users to think that the power is low. On the other hand, the speed reducing function by
the belt driving in the new type has enabled the torque increasing for the output shaft.
(3) Less vibration caused against the body
Compared with he conventional type, the vibration has been extremely minimized.
(4) Dust absorbing unit mounted
The dust absorbing unit built in this machine provides the clean and healthy working.
(5) Dust and water proof structure
Except for the motor, the dust and water proof structures are built in.
Accordingly the service life of the bearing inside the base(problem occurred in the conventional type before) and
the endurance has been extremely improved.
Through the use of water proof paper in addition to this water proof mechanism, the water grinding also becomes
possible.
(6) Corner grinding possible
If the frame cover on the duct absorbing unit is removed, it enables grinding using the full corner.
(7) Double insulation structure
Repair
(1) Disassembling
(a) Remove the steel band(for holding the rubber sleeve)mounted on the base from between the base and the frame.
(b) Remove the push buttons(2 pieces at back/forth) protruded above the top of frame.
(c) Remove the bearing retainer at center on the base. To disconnect it, place the minus screw driver on the cracked
point on the bearing retainer and turn the bearing retainer in left.
(d) Remove the pan head screw M5x12 holding the balance weight on the bearing #6003ZZ. At this time insert the
minus screw driver into the rubber sleeve to protect the balance weight from turning for easy disconnection.
(e) Next disconnect the base. If hard to disconnect it due to the base tightly connected, insert the screw driver
between the frame and the base and disconnect while slightly twisting the driver.
(2) Cautions in assembling
(a) Slightly grease the Grease(Albania No.2)on the needle bearing housed in the frame.
(b) When assembling the base, assemble it so that the face at base side can be parallel to the face at the frame side.
