9.Chip cover

Chip cover prevents chips from flying off and improves the efficiency of dust collector.

Insert the chip cover between the base and lever, and push with a slight pressure until it catches in place. (Fig. 7)

When removing chip cover, hold both sides of knob and slightly open until it can be removed from the Jig Saw. (Fig. 8)

NOTE:

There is a possibility that chip cover is frosted when cutting the metal.

10.Sub base

Using the sub base (made from steel) will reduce abrasion of aluminium base especially in cutting metals.

Using the sub base (made from resin) will reduce scratching of cut surface. Attach the sub base to the bottom surface of base by attached 4 screws.

CUTTING

CAUTION:

In order to prevent blade dislodging, damage or excessive wear on the Plunger, please make sure to have surface of the base plate attached to the work piece while sawing.

1.Rectilinear cutting

When cutting on a straight line, first draw a marking gauge line and advance the saw along that line. Using the guide (sold separately) will make it

possible to cut accurately on a straight line.

(1)Loosen the base bolt hexagonal bar wrench attached on base. (Fig. 9)

(2)Move the base fully forward (Fig. 10), and tighten the base bolt again.

(3)Attach the guide by passing it through the attachment hole on the base and tighten the M5 bolt. (Fig. 11)

(4)set the orbital position to “0”.

NOTE:

To ensure accurate cutting when using the Guide (Fig. 11) always set the orbital position to “0”

2.Sawing curved lines

When sawing a small circular arc, reduce the feeding speed of the machine. If the machine is fed too fast, it could cause the blade to break.

3.Cutting a circle or a circular arc

The guide also will be helpful for circular cutting. After attaching the guide by same way noted as above, drive the nail or screw into the material through the hole on the guide, then use it for a

axis when cutting. (Fig. 12)

NOTE:

Circular cutting must be done with the blade approximately vertical to the bottom surface of the base.

4. Cutting metallic materials

(1)Adjust the speed Dial between scales “3” and “4”.

(2)Set the orbital position to “0” or “1”.

(3)Always use an appropriate cutting fluid (spindle oil. soapy water, etc.). When a liquid cutting fluid is not avaiable, apply grease to the back surface of the material to be cut.

5.Pocket cutting

(1) In lumber

Aligning the blade direction with the grain of the wood, cut step by step until a window hole is cut in the center of the lumber. (Fig. 13)

(2) In other materials

When cutting a window hole in materials other than lumber, initially bore a hole with a drill or similar tool from which to start cutting.

6.Angular cutting

base can be swiveled to both sides by up to 45° for angular cutting. (Fig. 14)

(1)the base bolt by hexagonal bar wrench attached on base and move the base fully forward. (Fig. 9, 10)

(2)Align the scale (from 0 degrees to 45 degrees by 15-degree increments) of the semi-circular part of

the base with the [] mark on the gear cover. (Fig. 15)

(3)Tighten the M5 bolt again. (Fig. 9)

(4)Set the orbital position to “0”.

NOTE:

Angular cutting can not be done when adopting chip cover or dust collector.

CONCERNING CUTTING OF STAINLESS STEEL PLATES

CAUTION:

In order to prevent blade dislodging, damage or excessive wear on the Plunger, please make sure to have surface of the base plate attached to the work piece while sawing.

When cutting stainless steel plates, adjust the unit as described below:

1. Adjust the speed

Blade

Thickness of material

Dial Scale

No. 97

1.5 ~ 2.5 mm

Middle groove position

between scales “2”

 

 

and “3”

 

 

 

NOTE:

Dial scale reading is for reference only. The higher the speed is, the quicker the material is cut. But the service life of the blade will be reduced in this case. When the speed is too low, cutting will take longer, although the service life will be prolonged. Make adjustments as desired.

2.Set the orbital position to “0” NOTE:

When cutting use cutting fluid (oil base cutting fluid) to prolong the blade’s service life.

SELECTION OF BLADES

Accessory blades

To ensure maximum operating efficiency and results, it is very important to select the appropriate blade best suited to the type and thickness of the material to be cut. Three types of blades are provided as standard accessories. The blade number is engraved in the vicinity of the mounting portion of each blade. Select appropriate blades by referring to Table 1.
