This mini plunge saw is primarily intended for the sawing, longitudinally and trans-
versely, of solid wood, chipboard, plywood, plastic, aluminum, tiles and stone held in a
fixed position. Please note that the TCT blade pre-installed in the saw is intended for
wood only. Any other usage or modification to the device shall be considered as
incorrect use and could give rise to considerable dangers. Not suitable for commercial
use.
GETTING TO KNOW YOUR INI PLUNGE SAW

Setting the cutting depth
NOTE: If possible we recommend that the cutting
depth be set approximately 1/16” deeper than the
material thickness. This should help to ensure you
achieve a clean cut.
1) Lift the lock lever (A) Fig.3 to release the cutting
depth setting clamp (B).
2) ove setting clamp indicator (C) to the desired
depth of cut.
3) Lower the lock lever to secure depth of cut.
Selecting/changing a saw blade
•Universal TCT blade- cuts wood, plastic.
•Segment diamond blade- cuts ceramic tiles,
stone.
•HSS blade- cuts aluminum and sheet metal
See “Cutting” section for more specific information.
WARNING!: Incorrect positioning of the blade
can permanently damage the tool.
1) Set the cutting depth to maximum. See section
above.
2) Press and hold the spindle lock button (A) Fig.4.
3) Use hex. key (A) Fig.5 to loosen and remove
the cap screw and plain washer (B). Remove
the blade flange (C).
4) Press the plunge lock button (B) Fig.4 to lift up
the base plate (D) Fig.5.
5) Lift blade (E) Fig.5 up off the spindle then pull
from the tool to remove blade.
6) Install the desired blade in the reverse order.
NOTE: The arrows on the blade must turn in a
clockwise direction of rotation as shown.

Switching on the tool
WARNING!: Before switching the tool on, check
that the saw blade is properly fitted and runs
smoothly, and that the blade cap screw is well
tightened.
Connect the 120V plug to the power supply. The
LED power-on light (C) Fig.6 will turn on until the
tool is disconnected from the power supply.
Push the lock-off button (A) Fig.6 forward with the
forefinger, depress the ON/OFF trigger (B) firmly
and keep it pressed.
Once you release the trigger, the main switch
returns automatically to its initial position and the
tool turns off.
WARNING!: The saw blade continues to rotate
after the tool is switched off.
Releasing the plunge stop
Press the plunge lock button (A) Fig.7 downwards
and keep it pressed.
NOTE: Pressing the plunge lock button unlocks
the plunge cut mechanism, so that the motor can
be moved downwards. The saw blade emerges
below the base of the tool.
Setting the edge guide
Unscrew the edge guide lock knob (A) Fig.8 on
the base plate (B).
Slide the edge guide (C) in the slots (D).
Set a desired width and retighten the edge guide
lock knob (A).

Laser guide
WARNING!: Do not stare directly at the laser
beam, do not deliberately aim the beam at
personnel and ensure that it is not directed
towards the eye of a person for longer than 0.25s.
When you make a cut line on your workpiece,
the laser can help you get better alignment.
Turn on: Press the laser switch (A) Fig.9 to the
“I” position. Line the laser up with the cut line on
your workpiece.
Turn off: Press the switch (A) to “O” position.
In addition, a V-shaped notch (B) Fig.9 at the
front of base and a protruding pointer (C) at the
rear allow the user to accurately align the cutting
mark on the workpiece.
Dust extraction
This mini plunge saw is a powerful tool capable
of producing a large amount of dust. As the tool
has a fully enclosed blade, forced dust extraction
is particularly efficient. Forced dust extraction
should be used for all but small trimming jobs.
Push the dust extraction hose (A) Fig.10 onto the
dust extraction nozzle (B).
The dust extraction hose can be adapted to King
Wet-Dry Vacuums or others having a 1-1/4” hose
diameter as shown in Fig.10.

cutting
waRning!: Always cut in a forward direction. Never draw the tool backwards. If
you are a novice user, practice by cutting thin wood until proficient.
1) Install the correct blade ensuring it is sharp and not damaged.
2) Set the depth of cut.
3) Place the material to be cut onto a flat surface such as a workbench, table or floor.
Use a piece of scrap material underneath if you do not wish to damage the work
surface.
4) Plug into main power supply.
5) Grasp the tool firmly and rest its metal base plate onto the surface to be cut. Ensure
that the rear half of the base plate overhangs the work surface. Do not plunge the blade
into the material.
6) Switch on the tool and wait for a moment for the blade to run up to speed. Next,
depress the plunge lock button (A) Fig.7 and plunge the blade into the material slowly
and gently, but firmly. Then push the tool forward along the line to be cut. If necessary,
switch on the laser.
NOTES:
• Never draw the tool backwards.
• Very little force should be used to feed the tool along the cut. Excess force will cause
operator fatigue and excessive wear to the blade and tool.
• Ensure that the base plate is always held flat on the material being cut. This is
particularly important at the start or finish of a cut or if thin strips are being cut where the
base plate is not fully supported.
• Once the cut has been finished, lift the tool from the work surface before switching off.
If a lot of dust has been created, keep switched on for a few extra seconds to allow the
dust to clear from within the tool.
cut-outs
Plunge cutting may not be possible in some hard materials. Choose a suitable saw blade
for hard materials and change to it.
• If the cut is to be covered, for example by a vent cover, the corners can be overlapped
to ensure that the waste material is completely detached.
• If the cut-out is to be seen, do not overlap the corners. In this circumstance, as the
cutting blade is circular, the waste material will not be fully detached. The corners will
therefore, require finishing with a knife. If the material is thin and the back surface
unimportant, the waste material can just be pushed out.
• Where there is access to the back surface of the material to be cut, the cut-out can be
marked out with an over cutting allowance. The cut is then made from the back surface
to ensure perfect corners on the front surface.
OPERATION

CUTTING ARTICULARLY TOUGH OR ABRASIVE MATERIALS
Learn to use the tool by cutting wood before attempting to cut anything tougher. When
cutting tougher material, such as metals, more force is required to hold the workpiece
and clamping may be required.
Sheet metal: Use the HSS balde. Always set the depth adjustment to at least 1 mm
deeper than the material thickness to avoid the blade riding up over the surface. Scrap
material is required underneath the work surface.
• Remove burrs and rust as these impede the feed across the material.
• Thick beeswax (furniture polish) applied to the base plate of the tool makes metal
cutting easier.
• Only suitable for cutting brass, copper, lead, aluminium or galvanised mild steel.
• Every 2 minutes of metal cutting should be followed by a rest of at least 3 minutes.
Ceramic tiles, stone: Use the segmented diamond balde.
•Always use with a suitable vacuum connected as the dust can be hazardous to the
operator and prevent the guard from operating correctly.
CLEANING AND MAINTENANCE
Regular cleaning is required for the safe operation of the tool, as an excessive build up
of dust will prevent the tool from operating correctly.
• The dust extraction hose may block and require cleaning occasionally, especially if
damp wood is being cut. Clean thoroughly with a small soft brush, like a paint brush.
• Keep the cooling vents on the motor housing clean and unobstructed at all times.
• Never use any caustic agents or solvents to clean the plastic parts.
Blades
Always use a sharp blade. If the tool does not cut as well as expected or if it overheats
the most common cause is a blunt blade. It is difficult to see or feel if the blade is blunt.
When in doubt use a new blade.
• Replacement blades are available at your nearest distributor of King Canada products.
