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

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)
Hold the tool by both hands as shown in the figure with
the stopper plate contacting the workpiece and the blade
clear of the workpiece. (Fig. 13)
Turn the tool on and wait until the blade attains full speed.
Gently lower the blade into the cut. The weight of the tool
or slightly pressing the tool will supply adequate pressure
for the cutting. Do not force the tool.
As you reach the end of a cut, release pressure and,
without actually raising the tool, lift it slightly so that it will
not fall against the workpiece.
CAUTION:
• Applying excessive pressure to the tool or twisting of
the blade may cause bevel cutting or damage to the
blade.
• When not using the tool for a long period of time,
remove the blade from the tool.
• If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
Cutting lubricant
When cutting metals, use Makita cutting wax as a cutting
lubricant. To apply the cutting wax to the blade teeth, start
the tool and cut in to the cutting wax as shown in the
figure after removing a cap of the cutting wax. (Fig. 14)
CAUTION:
• Never use cutting oil or apply excessive amount of wax
to the blade. It may cause the blade to slip or come off
unexpectedly.
• When cutting cast iron, do not use any cutting wax.
