NOTE:
• If the tool is operated continuously at low speeds for a
long period of time, the operation life of the motor will
be reduced.
• 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.
The tools equipped with electronic function are easy to
operate because of the following features.
Constant speed control
Electronic speed control for obtaining constant speed.
Possible to get fine finish, because the rotating speed is
kept constant even under load condition.
Soft start feature
Safety and soft start because of suppressed starting
shock.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing the saw blade
CAUTION:
• Always clean out all chips or foreign matter adhering to
the blade, blade clamp and/or slider. Failure to do so
may cause insufficient tightening of the blade, resulting
in a serious injury.
To install the saw blade, always make sure that the blade
clamp lever is in released position
cover before inserting the saw blade. If the blade clamp
lever is in fixed position, rotate the blade clamp lever in
the direction of the arrow so that it can be locked at the
released position . (Fig. 6)
Insert the saw blade into the blade clamp as far as it will
go. The blade clamp lever rotates and the saw blade is
fixed. Make sure that the saw blade cannot be extracted
even though you try to pull it out. (Fig. 7)
NOTE:
• If you do not insert the saw blade deep enough, the
saw blade may be ejected unexpectedly during
operation. This can be extremely dangerous.
If the lever is positioned inside the tool, switch on the tool
just a second to let the blade out as shown in the figure.
Switch off and unplug the tool from the mains.
To remove the saw blade, rotate the blade clamp lever in
the direction of the arrow fully. The saw blade is removed
and the blade clamp lever is fixed at the released position
. (Fig. 8)

NOTE:
• Keep hands and fingers away from the lever during the
switching operation. Failure to do so may cause
personal injuries.
• If you remove the saw blade without rotating the blade
clamp lever fully, the lever may not be locked in the
released position
clamp lever fully again, then make sure that the blade
clamp lever locked at the released position
OPERATION (Fig. 9)
CAUTION:
• Always press the shoe firmly against the workpiece
during operation. If the shoe is removed or held away
from the workpiece during operation, strong vibration
and/or twisting will be produced, causing the blade to
snap dangerously.
• Always wear gloves to protect your hands from hot
flying chips when cutting metal.
• Be sure to always wear suitable eye protection which
conforms with current national standards.
• Always use a suitable coolant (cutting oil) when cutting
metal. Failure to do so will cause premature blade
wear.
Press the shoe firmly against the workpiece. Do not allow
the tool to bounce. Bring the blade into light contact with
the workpiece. First, make a pilot groove using a slower
speed. Then use a faster speed to continue cutting.
MAITENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or

maintenance.

• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Replacing carbon brushes (Fig. 10)
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
secure the brush holder caps. (Fig. 11)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
