RIP SCALE POINTER

NOTE: The rip scale pointer will need to be readjusted whenever a thicker or thinner blade is installed.

On-Off Switch

Lift the switch paddle up to turn your saw ON and push it down to turn your saw OFF.

A hole is provided in the switch for insertion of a padlock to lock the saw off (Fig. 17).

WARNING: Be sure switch is in the OFF position before plugging machine in.

Adjustments

NOTE: All settings on your saw have been accurately adjusted at the factory.

RAIL LOCK ADJUSTMENT

1.Lock the rail lock lever (Fig. 9) by pushing down.

2.On the underside of your saw, tighten the nut shown in Figure 18. Adjust this nut until the gap between the belville washers closes.

3.Once the springs are almost touching, loosen the nut 1/2 turn.

RIP SCALE ADJUSTMENT

See “ADJUSTING THE RIP SCALE” on page 5.

BEVEL STOP AND POINTER ADJUSTMENT

1.Raise the blade fully by rotating the blade height adjustment wheel clockwise until it stops.

2.Unlock the bevel lock lever (Fig. 3) by pushing it up and to the right. Loosen the bevel stop screw (Fig. 19).

3.Place a square flat against the table top and against the blade between teeth, as shown in Fig. 20. Ensure the bevel lock lever is in its unlocked, or up, position.

4.using the bevel lock lever, adjust the bevel angle until it is flat against the square.

5.Tighten the bevel lock lever by pushing it down.

6.Turn the bevel stop cam until it firmly contacts the bearing block. Tighten the bevel stop screw.

7.Check the bevel angle scale. If the pointer does not read 0°, loosen pointer screw (see Fig. 19) and move the pointer so it reads correctly. Retighten the pointer screw.

8.Repeat at 45°, but do not adjust pointer.

MITRE GAUGE ADJUSTMENT

Your mitre gauge features adjustable stops at 90° and 45° left and right. To adjust these stops, loosen the lock nuts and tighten or loosen the three adjusting screws against the stop plate (see Fig. 21).

FENCE PARALLEL ADJUSTMENT

1.Unlock rail lock lever.

2.Locate rear pinion bearing and loosen the two hex bolts just enough to allow side-to-side movement.

3.Adjust fence parallel to blade.

4.Lock rail lock lever and check parallel alignment of the blade.

5.Tighten the 2 hex bolts that secure the rear pinion bearing assembly to the table. NOTE: If there is not enough travel in the pinion bearing assembly to allow the fence to be parallel to the blade, take the unit to an authorised service centre.

RACK AND PINION MESH ADJUSTMENT

Proper adjustment of the rack and pinion mesh is done at the factory. If it should become necessary to adjust the rack and pinion mesh, use the following procedure.

1.Turn the saw upside down and locate the front pinion bearing.

2.Using a narrow blade screw driver or #20 torx driver, access the screw through the slot. Loosen the screw (counterclockwise) until the head touches the inside of the bearing box.

3.Tighten the screw (clockwise) 3/4 of a turn.

4.Repeat procedure for rear pinion bearing

Saw Blades

THIS SAW IS INTENDED FOR THE USE OF BLADES 10” IN DIAMETER OR SMALLER

1.The saw blade furnished with your new saw is a 10” (254mm) combination blade, used for cross cutting (across the grain) and ripping (with the grain) through the material. This blade will produce a good quality cut for most applications.

2.There are many types of blades available to do specific and special jobs such as cross cut only, rip only, hollow ground, thin plywood, paneling, etc.

3.Use only saw blades designed for maximum safe operating speeds of 5,000 RPM or greater.

4.Saw blades should always be kept sharp. It is recommended that you locate a reputable sharpening service to sharpen your blades when needed.

5.Never stack blades on top of one another to store. Place material such as cardboard between them to keep the blades from coming in contact with one another.

CAUTION: Abrasive wheels should not be used on this saw.

Kickback

Kickback is a dangerous condition! It is caused by the workpiece binding against the blade. The result is that the workpiece can move rapidly in a direction opposite to the
