Groove cutting

CAUTION:
Be sure to move the tool forward
in a straight line gently. Forcing or twisting the tool
may result in overheating the motor and dangerous
kickback, possibly causing severe injury.
CAUTION:
Never approach any part of your
body under the tool base when section cutting,
especially at starting. Doing so may cause serious per-
sonal injuries. The blade is exposed under the tool base.
CAUTION:
Use eye protection to avoid injury.
CAUTION:
For groove cutting operation,
always connect the tool to a vacuum cleaner.
CAUTION:
Hold the tool firmly. The tool is
provided with both a front grip and rear handle.
Use both to best grasp the tool. If both hands are
holding saw, they cannot be cut by the blade.

Adjust the depth of cut.
2. Set the tool on the guide rail.
3. Align the guide rail along the cutting line with using
the guide plate. Make sure that the blade does not
make any contact with workpiece.
4. Push in the lock-off button and turn the tool on,
and wait until the blade attains full speed.
5. Press down the tool slowly to the preset depth of cut, and
simply move the tool forward over the workpiece surface, keep-
ing it flat and advancing smoothly until the cutting is completed.
6. When cutting is complete, release switch, wait for
blade to stop and then withdraw tool.
To get clean cuts, keep your cutting line straight and your
speed of advance uniform. If the cut fails to properly follow
your intended cut line, do not attempt to turn or force the
tool back to the cut line. Doing so may bind the blade and
lead to dangerous kickback and possible serious injury.
Plunge cutting (Cutting-out)
WARNING:
observe the following instructions.
1. Place the tool on the guide rail with the rear edge
of tool base against a fixed stop or equivalent which is
clamped on the guide rail.
► Fig.24: 1. Fixed stop
2. Hold the tool firmly with one hand on the front grip
and the other on the tool handle. Push in the lock-off
button, and turn the tool on, then wait until the blade
attains full speed.
3. Press down the saw head slowly to the preset
depth of cut, and move the tool forward to the desired
plunge position.
NOTE: The triangular mark on the blade case shows
the approximate center of the blade.

MAINTENANCE

CAUTION:
Always be sure that the tool is
switched off and unplugged before attempting to
perform inspection or maintenance.
CAUTION:
Clean out the guard to ensure
there is no accumulated sawdust and chips
which may impede the operation of the guarding
system. A dirty guarding system may limit the proper
operation which could result in serious personal
injury. The most effective way to accomplish this
cleaning is with compressed air. If the dust is being
blown out of the guard, be sure the proper eye
and breathing protection is used.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
Replacing carbon brushes
► Fig.26: 1. Limit mark
Check the carbon brushes regularly.
Replace them 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.
1. Use a screwdriver to remove the brush holder
caps.
2. 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
