3. OPERATION
BLADE INSTALLING
WARNING: Always switch off and unplug the power tool prior to any adjustment,
servicing or maintenance or in case of mains drop-out.
• Remove the fence (4).
• Press the blade (7) slightly to the roller guide (10).
• Rotate the blade quick release button (15).
• Pull the blade out.
INSTALLING THE BLADE
WARNING: Always switch off and unplug the power tool prior to any adjustment,
servicing or maintenance or in case of mains drop-out.
• Insert the blade until you hear an audible click, indicating that the blade shank
has entered into the fixing apertures.
• Check to make sure the quick release button (15) is back in its initial position.
• Restore the fence (4).
WARNING: Never operate the saw without the fence (4) mounted.
GENERAL CUTTING
Rest the front of the base plate on the workpiece and align the blade cutting edge
with the line marked on the workpiece. Ensure that the supply cord is out of the way
of the saw blade and the cutting line. Switch the saw on and move it forward in the
material. Apply only pressure to keep the saw steady and the blade running.
WARNING: Do not force the saw to prevent motor overheating and blade breakage.
To achieve maximum efficiency and high quality of the cut, use blades, suitable for
the specific job and the processed material.
PENDULUM ACTION
The saw pendulum action ensures maximum efficiency, reducing the friction and
heat generation and improves chip ejection. With the pendulum action engaged the
blade cuts through the material at upstroke but does not drag in the material at
downstroke. Switching and setting the pendulum action is achieved by rotating
knob (8).
• Select higher settings (3) for the knob for fast cutting in soft material.
• Use setting (0) without pendulum action when cutting hard material.
STRAIGHT CUTTING
Straight cutting is performed by guiding the base plate slide along a lath or
straightedge clamped to the material. Cut the material in one direction only;
do not cut halfway to complete the cut from the opposite side.
CURVE CUTTING
To perform curve cutting guide the direction of the cut by applying pressure on the
handle.
WARNING: Excessive side pressure on the blade may result in blade breakage.
BEVEL CUTTING
Bevel cuts can be adjusted from 0° to 45° right or left. Bevel cutting angles in 15°
increments are marked on the scale (6) on both the right and left side of the base
plate (5).

3. OPERATION
Setting the angle at intermediate positions is possible using of a protractor. In this
case the angle is fixed by the screws only.
Adjusting the angle
• Loosen the base retaining screws with the hex wrench (14) supplied with the tool
until the base can move freely.
• Slide the base back slightly to release it from the tab on the motor housing.
• Align the mark on the base to the desired angle with the edge on the motor
housing.
• Once the desired angle is reached, slide the base forward until the tab on the
motor housing aligns with the corresponding notch on the base rear.
• Re-tighten the base retaining screws with the hex wrench to secure the base.
PLUNGE CUTTING
WARNING: To avoid loss of control, broken blade or damage to the material
being cut, always use extreme caution when performing plunge cuts.
We do not recommend plunge cutting on materials other than wood.
• Mark the cutting line clearly on the material.
• Set the cutting angle at 0°.
• Tilt the saw forward so that it rests on the front edge of the base and the blade will
not contact the material when the saw is switched on.
• Ensure that the blade is inside the area to be cut.
• Switch the saw on at high speed and slowly feed the blade toward the material
until the blade cuts through the wood.
• Continue lowering the blade into the material until the base rests on the material
surface, then move the saw forward to complete the cut.
CUTTING METAL
You can saw various metals with this saw. Be careful not to twist or bend the blade.
Do not apply too much pressure. If the blade chatters or vibrates excessively, use
a finer tooth blade, suitable for the processed material or the specific operation or
select higher speed. If the blade heats excessively, use lower speed. If the blade
teeth become filled or clogged when cutting soft metals, such as aluminium, use a
coarser-tooth blade or lower speed. We recommend applying oil along the cutting
line to keep the blade cool, increase efficiency, and prolong blade life.
Clamp the material firmly and cut close to the clamping point to eliminate any
vibration of the workpiece being cut. When cutting conduit, pipe or angle iron,
clamp work in a vice if possible and saw close to the vice. To cut thin sheet, place
the sheet between two hardboard or ply wood supports, and clamp the layers to o
eliminate vibration and material tearing thus achieving a clean and smooth cut.
Lay out your pattern or line of cut on the top layer.
IMPORTANT: When cutting metal, keep the exposed portion of saw bar clean and
free of metal chips by wiping frequently with an cloth soaked in oil. Use extreme
caution in disposing of this cloth after completion of job to prevent potential fire
hazard.
