Functional Description; Maintenance - Makita 9741 Instruction Manual

FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Adjusting front roller (Fig. 1)
The front roller allows you to apply uniform pressure to the
workpiece. To adjust the front roller, set the tool on a flat
surface and loosen the wing nut. Adjust the front roller up
or down until the clearance distance (D) is about 2 mm.
Tighten the wing nut securely.
Switch action (Fig. 2)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
To start the tool, simply pull the switch trigger. Release the
switch trigger to stop.
For continuous operation, pull the switch trigger and then
push in the lock button.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing wheel
To remove the wheel, insert one hex wrench into the end
of the spindle and another hex wrench into the end of the
output shaft. Turn the hex wrench in the output shaft
clockwise while securely holding the hex wrench in the
spindle so that the wheel cannot revolve. Pull the output
shaft out from the wheel. Move the wheel slightly away
from the spindle and remove the wheel from the tool.
(Fig. 3)
NOTE:
• The output shaft has a left hand thread.
To install the wheel, follow the removal procedures in
reverse. When installing it, be sure to align the notches in
the wheel with the pins on the spindle. (Fig. 4)
Connecting to dust collector (Fig. 5)
The use of a dust collector makes sanding operations
clean and dust collection easy. To connect a dust collec-
tor, open the dust port by sliding the cover plate up and in
a clockwise direction. Attach the joint onto the dust port.
Now a dust collector can be connected to this tool.
CAUTION:
• When not using a dust collector, close the dust port
opening with the cover plate.
OPERATION (Fig. 6)
Hold the tool firmly with both hands on the handle and the
grip in front. Place the tool on the workpiece surface and
move the tool gently forward and backward while applying
slight downward pressure.
CAUTION:
• The tool should not be in contact with the workpiece
surface when you turn the tool on or off. Damage to the
tool or the workpiece surface and injury to the operator
may result.
• Apply slight downward pressure only. Excessive pres-
sure may decrease tool efficiency, shorten wheel ser-
vice life and possibly gouge the workpiece surface.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
Replacing carbon brushes
Remove and check the carbon brushes regularly. Replace
when they wear down to the limit mark. Keep the carbon
brushes clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes. (Fig. 7)
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts. (Fig. 8)
