Blade guard cleaning
When changing blade, make sure to also clean the
upper and lower blade guards of accumulated metal
chips as discussed in the Maintenance section. Such
efforts do not replace the need to check lower guard
operation before each use.
Rip fence (guide rule) (Accessory)
► Fig.9: 1. Rip fence (Guide rule) 2. Screw
The handy rip fence (guide rule) allows you to do
extra-accurate straight cuts. Simply slide the rip fence
up snugly against the side of the workpiece and secure
it in position with the clamp screw on the front of the
base. It also makes repeated cuts of uniform width
possible.
OPERATION
CAUTION:
•
► Fig.10: 1. Carbide-tipped saw blade 2. Workpiece
Hold the tool firmly with both hand. Set the base plate on the
workpiece to be cut without the blade making any contact. Then
turn the tool on and wait until the blade attains full speed. Move
the tool forward over the workpiece surface, keeping it flat and
advancing smoothly until the cutting is completed. Keep your
cutting line straight and your speed of advance uniform.
The sight window in the base makes it easy to check the dis-
tance between the front edge of the saw blade and the work-
piece whenever the blade is set to the maximum depth of cut.

7 ENGLISH
Never twist or force the tool in the cut. This may
cause motor overload and/or a dangerous kick-
back, resulting in serious injury to the operator.
When making a miter cuts etc., sometimes the lower guard
does not move easily. At that time, use the retracting lever
to raise the lower guard for starting cut and as soon as
blade enters the material, release the retracting lever.
Do not use a deformed or cracked blade.
Replace it with a new one.
Do not stack materials when cutting them.
Do not cut hardened steel, stainless steel, aluminum,
wood, plastics, concrete, tile, etc. Cut only mild steel.
Do not touch the saw blade, workpiece or cutting
chips with your bare hand immediately after cutting,
they may be extremely hot and could burn your skin.
Always use the carbide-tipped saw blades
appropriate for your job. The use of inappropri-
ate saw blades may cause a poor cutting perfor-
mance and/or present a risk of personal injury.
Always be sure that the tool is switched off and
unplugged before removing or installing the dust cover.
The dust cover may become hot due to hot chips. Do not
touch the cutting chips or dust cover with your bare hand.
Do not turn the tool upside down. The cutting
chips accumulated inside the dust cover may fall
out of the dust cover.
Handle the dust cover carefully so that it will not
be deformed or damaged.
