13. Do not operate the tool at no-load unneces-
sarily.
14. Always use the correct dust mask/respirator
for the material and application you are work-
ing with.
15. Some material contains chemicals which may
be toxic. Take caution to prevent dust inhala-
tion and skin contact. Follow material sup-
plier safety data.
SAVE THESE INSTRUCTIONS.
WARNING:
MISUSE or failure to follow the safety rules stated
in this instruction manual may cause serious
personal injury.
OPERATING INSTRUCTIONS
Installing or removing battery cartridge (Fig. 1)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while sliding the button on the side 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 you can see the red part on
the upper side of the button, it is not locked completely.
Insert it fully until the red part cannot be seen. 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.
Adjusting shoe (Fig. 2)
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 counter-clockwise and slide the shoe for-
ward or back to the desired position. Then tighten the
lever clockwise to firmly secure the shoe.
Switch action (Fig. 3)
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 switch trigger from being accidentally
pulled, a lock-off button is provided.
To start the tool, press in the lock-off button and pull the
switch 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 switch trigger. Release the
switch trigger to stop.
Speed change (Fig. 4)
CAUTION:
• Always set the speed change lever fully to the correct
position. If you operate the tool with the speed change
lever positioned half-way, the tool may be damaged.
• Do not use the speed change lever while the tool is run-
ning. The tool may be damaged.
To change the speed, first switch off the tool and then
slide the speed change lever to the A side (2) for high
speed or B side (1) for low speed. Be sure that the speed
change lever is set to the correct position before opera-
tion. Use the right speed for your job.
ASSEMBLY
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.
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. 5)
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. 6)
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. 7)
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.
OPERATION (Fig. 8)
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.
• Always use a suitable coolant (cutting oil) when cutting
metal. Failure to do so will cause premature blade
wear.
• If the tool is operated continuously until the battery car-
tridge has discharged, allow the tool to rest for 15 min-
utes before proceeding with a fresh battery.
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.
