Makita BSR730 Manual De Instrucciones página 9

NOTE:
• The battery charger is for charging Makita-battery cartridge. Never use it for other purposes or for other manufac-
turer's batteries.
• When you charge a new battery cartridge or a battery cartridge which has not been used for a long period of time, it
may not accept a full charge. This is a normal condition and does not indicate a problem. You can recharge the bat-
tery cartridge fully after discharging it completely and recharging a couple of times.
• If you charge a battery cartridge from a just-operated tool or battery cartridge which has been left in a location
exposed to direct sunlight for a long time, the charging light may flash in red color. If this occurs, wait for a while.
When the temperature on battery is more than approx. 70°C, two charging lights may flash in red color, and when
approx. 50°C – 70°C, one charging light in red color. Charging will begin after the battery cartridge is cooled by the
cooling fan installed in the charger (DC24SA only).
• If the charging light flashes alternately in green and red color, charging is not possible. The terminals on the charger
or battery cartridge are clogged with dust or the battery cartridge is worn out or damaged.
• Any of the following conditions indicates damage to the charger and/or battery cartridge. Ask your Makita Authorized
or Factory Service Center to check them.
1) The charging light does not flash (green) when the battery charger is plugged into a power source.
2) The charging light does not light up or flash (red) when the battery is inserted in the charger port.
3) Charging is not completed at even more than two hours after red light comes ON at start of charging.
Removing or installing saw blade
Important:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before removing or installing
the blade.
The following blade can be used with this tool.
Max. dia. Min. dia.
190 mm 170 mm
The thickness of the riving knife is 1.8 mm.
CAUTION:
• Do not use saw blades which do not comply with the
characteristics specified in these instructions.
• Do not use saw blades the disc of which is thicker or
the set of which is smaller than the thickness of the riv-
ing knife.
To remove the blade, press the shaft lock so that the
blade cannot revolve and use the hex wrench to loosen
the bolt counterclockwise. Then remove the bolt, outer
flange and blade. (Fig. 10)
To install the blade, follow the removal procedure in
reverse. BE SURE TO TIGHTEN THE BOLT SECURELY.
(Fig. 11)
CAUTION:
• Be sure the blade is installed with teeth pointing up at
the front of the tool.
• Use only the Makita hex wrench to remove or install the
blade.
Riving knife adjustment (Fig. 12)
Use the hex wrench to loosen the hex socket head bolt
for the riving knife adjustment, then raise the safety cover
(safety guard). Move the riving knife up or down over the
protuberance for settings indicated in Fig. 12, so as to
obtain the proper clearance between the riving knife and
saw blade.
CAUTION:
Ensure that the riving knife is adjusted such that:
The distance between the riving knife and the toothed rim
of the saw blade is not more than 5 mm. The toothed rim
does not extend more than 5 mm beyond the lower edge
of the riving knife.
Blade
Kerf
thickness
1.6 mm 1.9 mm
or less or more
Hex wrench storage (Fig. 13)
When not in use, the hex wrench can be conveniently
stored.
CAUTION:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before any adjustment is
attempted.
Adjusting depth of cut (Fig. 14)
Loosen the lever on the depth guide and move the base
up or down. At the desired depth of cut, secure the base
by tightening the lever.
CAUTION:
• Use a shallow depth of cut when cutting thin work-
pieces for cleaner, safer cuts.
• After adjusting the depth of cut, always tighten the lever
securely.
Bevel cutting (Fig. 15 & 16)
Loosen the clamp screws in front and back. Set for the
desired angle (0° – 50°) by tilting accordingly, then tighten
the clamp screws securely.
Use the 45° stopper when you do precise 45° angle cut-
ting. Turn the lever clockwise fully for bevel cuts (0° – 45°)
and turn it counterclockwise for 0° – 50° bevel cuts.
Adjusting for accuracy of 90° and 45° cut
(vertical and 45° cut) (Fig. 17 & 18)
This adjustment has been made at the factory. But if it is
off, adjust the adjusting screws with a screwdriver while
inspecting 90° or 45° the blade with the base using a tri-
angular rule or square rule etc.
CAUTION:
After adjusting the depth of cut and bevel cutting angle,
be sure to tighten the lever on the depth guide and the
clamp screws in front and back.
Sighting (Fig. 19)
For straight cuts, align the right notch in the front of the
base with your cutting line on the workpiece. For 45°
bevel cuts, align the left notch with it.
