Fig.6
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.7
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.8
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.9
Select the proper cutting position for your workpiece by
referring to the figure.
Fig.10
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.11
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.12
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.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may
result.
Cleaning
After use, remove wax, chips and dust from the tool,
wheel tires and blade.
CAUTION:
• Never use solvents such as turpentine, gasoline,
lacquer, etc. to clean plastic parts.
• Wax and chips on the tires may cause the blade to
slip and come off unexpectedly. Use a dry cloth to
remove wax and chips from the tires.
Replacing tires on wheels
Fig.13
When the blade slips or does not track properly because
of badly worn tires, or the lip of the tire on motor side gets
damaged, the tires should be replaced.
Replacing carbon brushes
Fig.14
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.
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
