Operation; Installing Or Removing The Blade - Makita DPB180 Instruction Manual

In this situation, release the switch trigger on the tool
and stop the application that caused the tool to
become overloaded. Then pull the switch trigger
again to restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before pulling the
switch trigger again.
• Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. In this situation, remove and
recharge the battery.
Switch action (Fig. 3)
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the "OFF" position when
released.
To prevent the switch trigger from accidentally pulled, the
lock-off button is provided.
To start the tool, depress the lock-off button from B side
and pull the switch trigger.
Release the switch trigger to stop. After use, always press
in the lock-off button from A side.
Speed adjusting dial (Fig. 4)
The tool speed can be infinitely adjusted between 1.4 m/s
and 2.7 m/s by turning the adjusting dial. Higher speed is
obtained when the dial is turned in the direction of number
6; lower speed is obtained when it is turned in the
direction of number 1.
Select the proper speed for the workpiece to be cut.
CAUTION:
• The speed adjusting dial can be turned only as far as 6
and back to 1. Do not force it past 6 or 1, or the speed
adjusting function may no longer work.
Lighting up the lamp (Fig. 5)
CAUTION:
• Do not apply impact to the lamp, which may cause
damage or shorted service time to it.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The lamp goes out 10 - 15 seconds after releasing the
trigger.
NOTE:
• Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower
the illumination.
• Do not use thinner or gasoline to clean the lamp. Such
solvents may damage it.
• When the tool is overloaded during operation, the lamp
flickers.
• When the remaining battery capacity becomes small,
the lamp flickers.

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out any
work on the tool.

Installing or removing the blade

CAUTION:
• Oil on the blade can cause the blade to slip or come off
unexpectedly. Wipe off all excess oil with a cloth before
installing the blade.
• Use caution when handling the blade so that you are
not cut by the sharp edge of the blade teeth.
Turn the blade tightening lever clockwise until it hits
against the protrusion on the frame. (Fig. 6)
Match the direction of the arrow on the blade to that of the
arrow on the wheels. (Fig. 7)
Insert the blade between the bearings of the upper holder
first and then into the lower holder. The blade back should
contact the bearings in the lower portion of the upper
holder and lower holder.
Position the blade around the wheels and insert the other
side of the blade within the upper holder and lower holder
until the blade back contacts the bottom of the upper
holder and lower holder. (Fig. 8 & 9)
Put the blade into the groove in the blade guide.
Hold the blade in place and turn the blade-tightening lever
counterclockwise until it hits against the protrusion on the
frame. This places proper tension on the blade. Make
sure that the blade is correctly positioned within the blade
guard and around the wheels.
Start and stop the tool two or three times to make sure
that the blade runs properly on the wheels.
CAUTION:
• While making sure that the blade runs on the wheels
properly, keep your body away from the blade area.
To remove the blade, follow the installation procedure in
reverse.
CAUTION:
• When turning the blade tightening lever clockwise to
release the tension on the blade, point the tool
downward because the blade may come off
unexpectedly.
Adjusting the protrusion of stopper plate
(Fig. 10)
In the ordinary operation, protrude the stopper plate to the
A side fully. When the stopper plate strikes against the
obstacles like a wall or the like at the finishing of a cut,
loosen two screws and slide it to the B side in the figure.
After sliding the stopper plate, secure it by tightening two
screws firmly.

OPERATION

It is important to keep at least two teeth in the cut.
(Fig. 11)
Select the proper cutting position for your workpiece by
referring to the figure. (Fig. 12)
