Riving knife adjustment (Fig. 12)
Use the hex wrench to loosen the hex socket head
bolt for the riving knife adjustment, then raise the
safety cover (safety guard). Move the riving knife up
or down over the protuberance for settings indicated
in Fig. 12, so as to obtain the proper clearance
between the riving knife and saw blade.
CAUTION:
Ensure that the riving knife is adjusted such that:
The distance between the riving knife and the toothed
rim of the saw blade is not more than 5 mm. The
toothed rim does not extend more than 5 mm beyond
the lower edge of the riving knife.
Hex wrench storage (Fig. 13)
When not in use, the hex wrench can be conveniently
stored.
CAUTION:
Always be sure that the tool is switched off and the
battery cartridge is removed before any adjustment is
attempted.
Adjusting depth of cut (Fig. 14)
Loosen the lever on the depth guide and move the
base up or down. At the desired depth of cut, secure
the base by tightening the lever.
CAUTION:
• Use a shallow depth of cut when cutting thin work-
pieces for cleaner, safer cuts.
• After adjusting the depth of cut, always tighten the
lever securely.
Bevel cutting (Fig. 15 & 16)
Loosen the clamp screws in front and back. Set for
the desired angle (0° – 50°) by tilting accordingly, then
tighten the clamp screws securely.
Use the 45° stopper when you do precise 45° angle
cutting. Turn the lever clockwise fully for bevel cuts
(0° – 45°) and turn it counterclockwise for 0° – 50°
bevel cuts.
Adjusting for accuracy of 90° and 45° cut
(vertical and 45° cut) (Fig. 17 & 18)
This adjustment has been made at the factory. But if
it is off, adjust the adjusting screws with a screwdriver
while inspecting 90° or 45° the blade with the base
using a triangular rule or square rule etc.
CAUTION:
After adjusting the depth of cut and bevel cutting
angle, be sure to tighten the lever on the depth guide
and the clamp screws in front and back.
Sighting (Fig. 19)
For straight cuts, align the right notch in the front of
the base with your cutting line on the workpiece. For
45° bevel cuts, align the left notch with it.

Switch action (Fig. 20)
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, depress the lock-off button and pull
the switch trigger. Release the switch trigger to stop.
Operation (Fig. 21)
Hold the tool firmly. Set the base plate on the work-
piece to be cut without the blade making any contact.
Then turn the tool on and wait until the blade attains
full speed. Now simply move the tool forward over the
workpiece surface, keeping it flat and advancing
smoothly until the sawing is completed. To get clean
cuts, keep your sawing line straight and your speed of
advance uniform.
CAUTION:
• Always insert the battery cartridge all the way until it
locks in place. 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.
• When operating overhead, always make sure the
battery cartridge is locked securely so that it will not
be fallen out of the tool. If not, it may accidentally fall
out of the tool, causing injury to you or someone
around you.
• The riving knife should always be used except when
plunging in the middle of the workpiece.
• Do not stop the saw blade by lateral pressure on the
disc.
• Always gently keep the tool moving straight ahead
when cutting. Forcing or twisting the tool will result
in overheating of the motor and dangerous kick-
back, possibly causing severe injury.
• If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for
15 minutes before proceeding with a fresh battery.
Rip fence (guide rule) (Fig. 22)
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.
Dust nozzle (Fig. 23 & 24)
When you wish to perform clean cutting operation,
connect a vacuum cleaner to your tool. Install the joint
on the tool using the screws. Then connect a hose of
vacuum cleaner to the joint.
