INSTALLING/REPLACING THE SAW BLADE (FIGS. 1 & 2)
Use saw blades with 4-1/2 inch (115 mm) diameter and 3/8 inch (10 mm) arbor. Do not use a blade that does 
not match the diameter or arbor size. The pre-installed blade has a body that is 1.2 mm thick and theeth that 
are 1.8 mm thick . Do not use a blade that is thicker than the included blades, as this will prevent the arbor 
screw from properly securing the blade. Replacement saw blades (Model BL11510W) can be purchased 
from wenproducts.com.
1. Unplug your mini circular saw from the power source.
2. Press down the spindle lock (Fig. 1) to prevent the blade from 
spinning. With the spindle lock pressed down, use the includ-
ed M5 hex wrench to loosen the arbor screw by turning it 
clockwise (Fig. 2).
3. Remove the arbor screw, washer and outer flange.
4. Push the blade release button (Fig. 3) and swing the base plate 
upwards. Carefully remove the existing blade.
5. With the base plate swung upwards as in Step 4, slide the new 
saw blade onto the spindle. Make sure the blade teeth beneath 
the base plate are pointing forward and the arrows printed on 
the blade point in the clockwise direction.
6. Replace the outer flange. Press the spindle lock (Fig. 1 - 1) 
and replace the arbor screw and washer. Fully tighten the ar-
bor screw by turning it counterclockwise with the hex wrench.

WARNING: Wear gloves when handling saw blades to 
prevent injuries in case the blade teeth are accidentally 
contacted.
NOTE: The quality of the cut depends on the condition 
of the saw blade. Never use a dull, rusty, or damaged 
blade. Before operation, check the condition of the 
blade and replace if the blade is worn-out or damaged.
