ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
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 blade clamp sleeve in the direction of the arrow
so that it can be locked at 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 opera-
tion. 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 locked at the
released position. In this case, rotate the blade clamp
sleeve fully again, then make sure that the blade clamp
sleeve locked at the released position.
OPERATION
CAUTION:
• 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.
• Always wear gloves to protect your hands from hot fly-
ing 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.

MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
Replacing carbon brushes (Fig. 8 & 9)
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.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
