450W 85mm hand-held mini electric circular saw

Assembly and operation

This mini circular saw is a versatile tool that is designed for use in confined work spaces. By selecting the appropriate cutting blades, it will cut copper and aluminum tubing, ceramic and marble tile, and assorted wood products. The following assembly and operating instructions will explain the tool and its operation in detail.

Install vacuum adaptor

The vacuum adaptor can be used to attach a workshop vacuum hose to the tool. This will prevent most cutting dust from escaping into the work area.

1.Line up the tabs on the small end of the vacuum adaptor (1) with the matching slots (2) in the vacuum port (3) in the rear of the mini circular saw (see Fig. 1).
2.Push the vacuum adaptor into the vacuum port as far as it will go.
3.Twist the vacuum adaptor clockwise to lock it into position.

Secure cord to vacuum hose

Slide the hook and loop strap (1) down the power cord (2) and wrap it around the vacuum hose (3) (see Fig. 2).

Remove blade guard

1.Insert 5 mm hex key (1) into the blade guard fulcrum nut (2) (see Fig. 3).
2.Turn hex key counter clockwise to remove the blade guard fulcrum nut.
3.Slide blade guard fulcrum bolt (3) out of the blade guard (4).
4.Carefully slide the blade guard off the tool.

Remove blade

1.Insert the 5 mm hex key (1) into the arbor screw (2) on the LEFT side of the tool (see Fig. 4).
2.Press inward on the spindle lock button (3) which is located on the RIGHT side of the mini circular saw.
3.Rotate the hex key CLOCKWISE while pressing on the spindle lock button until the spindle lock button engages the spindle.
4.Continue to rotate the arbor screw in a CLOCKWISE direction until the arbor screw is removed and the thick arbor washer (4) can be pulled off the arbor.
5.Remove the blade (5).

Select the correct blade

Before installing a blade into the mini circular saw, it is important to select the correct blade for the type of material being cut.

Install blade

1.Remove existing blade (if one is installed), arbor screw and thick arbor washer as noted above.
2.Slide blade (5) into the tool so the hole in the blade (6) slides over the arbor (see Fig. 5).
3.Re-install thick arbor washer and arbor screw in the reverse order in which they were removed.

4.Lock spindle using the spindle lock button and tighten the arbor screw by turning it COUNTER CLOCKWISE.
5.Re-install blade guard in the reverse order in which it were removed.

Adjust cutting depth

1.The cutting depth is controlled by limiting the amount of blade exposed below the blade guard.

2.Loosen the depth control knob (1) by turning it counter clockwise (see Fig 6).
3.Slide it upward toward the handle (2) and tighten the knob to hold the depth stop mechanism in place.
4.Press the blade guard lock button (3) and carefully pivot the blade guard (4) upward to expose the amount of blade (5) to achieve the desired depth of cut.

Install edge guide mount

1.Insert the edge guide dovetail (1) into the matching slot (2) in the front of the blade guard (see Fig 7a).
2.Slide the edge guide mount toward the right hand side of the blade guard until the mounting screw (3) lines up with the matching threaded hole (4) in the blade guard.
3.Carefully turn the mounting screw clockwise into the threaded hole until it holds the edge guide firmly in place.

4.Tighten the mounting screw using a 5 mm hex key.

Install edge guide

The mini circular saw can be used with an edge guide for ripping materials up to 6” wide.
1.Turn two edge guide locking screws (1) counter clockwise a few turns until the screws rise about 1/8” (see Fig. 7b).
2.Insert edge guard rod (2) into the edge guide mounting block slot (3).
3.Slide edge guard toward the mini circular saw until the desired width of cut is indicated on the scale (4) where it meets the edge of the edge guide mounting block.

4.Tighten both edge guide locking screws.

On/Off switch

This tool has dual purpose ON/OFF switch that is designed to prevent accidental starting of the tool. It also automatically turns the tool OFF then the switch is not held in the ON position.

1.Press the center of the switch (1) inward (see Fig. 8).
2.While holding the center of the switch inward, slide the switch button (2) forward until the tool starts.
3.To stop the mini circular saw, release the switch button. It will automatically turn the tool OFF.

Cutting (without edge guide)

1.Install appropriate cutting blade in the tool.
2.Adjust cutting depth as outlined.

3.Plug the tool cord into the power source.

4.Place leading edge of the blade guard (2) on the workpiece to be cut (see Fig. 10).

5.Grasp the tool with two hands. Place your right hand on the body of the tool (3) being careful not to cover the motor vents (4). Place your left hand on the forward part of the tool (5) so your thumb can operate the blade guard release button (6).

6.Line up front cut line indicator (7) with the cutting line marked on the workpiece (8).

7.Turn switch ON as outlined on Page 15.
8.Using the thumb on your left hand, press the blade guard release button (6).

9..Gently press downward on the front of the tool to raise the blade guard until it touches the depth control stop (9).
10.Re-check the alignment of the front cut line indicator (7) and the cutting line marked on the workpiece (8).
11.Slowly move the tool forward until the blade touches the workpiece and begins to cut at the cutting line.

Cutting(with edge guide)

To cut using the edge guide, follow the same basic principles as noted in Paragraphs 1 through 11 above. Instead of following a cutting line, you will simply set the edge guide at the appropriate width and hold the guide shoe (1) against the edge of the workpiece (2) to guide the blade in a straight line (see Fig. 11).
