10. Watch out for cut-off portions of the workpiece
being cut. They may fall and injure you or some-
one near you.
11. When cutting metals, be cautious of hot flying
chips.
12. Do not touch the blade or the workpiece immedi-
ately after operation; they may be extremely hot
and could burn your skin.
13. If you withdraw the blade from the workpiece
during operation, strong reaction will be pro-
duced, causing the blade to snap or causing you
to lose your grip and control of the tool. Always
switch off the tool and wait until the blade has
come to a complete stop before withdrawing the
blade from the workpiece.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Installing or removing battery cartridge (Fig. 3)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while pressing the push buttons on both sides of
the cartridge.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If not, it may accidentally fall out
of the tool, causing injury to you or someone around
you.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being inserted correctly.
Installing or removing 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 sleeve is in released position before inserting the
saw blade. If the blade clamp sleeve is in fixed position,
rotate the sleeve to the released position. (Fig. 4)
Insert the saw blade into the blade clamp as far as it will
go. The blade clamp sleeve 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. 5)
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.
To remove the saw blade, rotate the blade clamp sleeve
in the direction of the arrow fully. The saw blade is
removed and the blade clamp sleeve is fixed at the
released position. (Fig. 6)
NOTE:
If you remove the saw blade without rotating the blade
clamp sleeve fully, the sleeve may not be fixed. In this
case, rotate the blade clamp sleeve fully to make the
sleeve fixed at the released position.
Adjusting the shoe (Fig. 7)
When the blade loses its cutting efficiency in one place
along its cutting edge, reposition the shoe to utilize a
sharp, unused portion of its cutting edge. This will help to
lengthen the life of the blade. To reposition the shoe,
loosen the lever and slide the shoe forward or back to the
desired position. Then tighten the lever to firmly secure
the shoe.
Switch action (Fig. 8)
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 trigger from being accidentally pulled, a
lock-off button is provided. To start the tool, press in the
lock-off button and pull the trigger. The lock-off button
can be pressed in from either left or right side of the tool.
Tool speed is increased by increasing pressure on the
trigger. Release the trigger to stop.
Operation (Fig. 9)
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.
CAUTION:
• Always use a suitable coolant (cutting oil) when cutting
metal. Failure to do so will cause premature blade
wear.
• Always wear gloves to protect your hands from hot fly-
ing chips when cutting metal.
• Always press the shoe firmly against the workpiece
during operation. If the shoe is held away from the
workpiece during operation, strong vibration and/or
twisting will be produced, causing the blade to snap
dangerously.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before carrying out any work on
the tool.
Replacement of carbon brushes (Fig. 10 & 11)
Replace carbon brushes when they are worn down to the
limit mark. Both identical carbon brushes should be
replaced at the same time.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
