Assembling the saw (Fig. 1-5)

To adjust the turntable (17), loosen the locking screw (14) by approx. 2 turns, which frees the turntable (17).
Turn the turntable (17) and scale pointer (15) to the desired angular setting on the dial (16) and lock into place with the locking screw
(14). The saw has locking positions at angles of – 45°, -31.6°, -22.5°, -15°, 0°, 15°, 22.5°, 31.6° and 45°, at which the turntable (17) au-dibly clicks into position.
To release the saw from its position at the bottom, pull the fastening bolt (25) out of the motor mounting while pressing down lightly on the machine head (4). Turn the fastening bolt (25) through 90° before releasing it, so that the saw remains unlocked.
Swing the machine head (4) up until the re-lease lever (3) latches into place.
The clamping device (8) can be fitted on the left or right of the fixed saw table (18).
Undo the locking screws for the workpiece support (26).
Mount the workpiece support (10) on the fixed saw table (18) and tighten the appropri-ate locking screw (26) (Figure 4).
Mount the second workpiece support (10) on the opposite side of the saw and secure with the appropriate locking screw (26).
When the locking screw (21) is loosened, you can tilt the machine head (4) to the left by up to 45°.
To ensure that the saw is standing securely, adjust the adjustable foot (13) by turning it so that the saw stands in a horizontal and firm position.
Screw the additional feet (9) to the feet of the fixed saw table (18).
Then swing out the stability bar (36) to the rear until it engages.

Precision adjustment of the stop for crosscut 90° (Fig. 7-8)

Fasten the turntable (17) in 0° position.
Undo the locking screw (21) and move the machine head (4) all the way to the right using the handle (1).
Place the 90° angular stop (a) between the blade (7) and the turntable (17).
Adjust the adjustment screw (29) until the angle between the blade (7) and the turntable (17) equals 90°.
Finally check the position of the pointer (20) on the scale (19). If necessary, undo the poin-ter (20) with a Philips screwdriver, set it to the 0° position on the scale (19) and retighten the retainer screw.
No stop angle included.

recision adjustment of the stop for miter cut 45° (Fig. 1, 6, 7, 9)

Fasten the turntable (17) in 0° position.
Undo the locking screw (21) and move the machine head (4) all the way to the left using the handle (1), until it coincides at 45°.
Place the 45° stop angle (b) between the bla-de (7) and the turntable (17).

Adjusting the movable stop rails

Important. This saw is equipped with movable stop rails (34) that are screwed to the fixed stop rail (11).
For carrying out angle and miter cuts the mo-vable stop rails must be adjusted to prevent a collision with the saw blade.
For miter and angle cuts to the left, the left stop rail must be moved outwards. For angle cuts to the right, the right stop rail must be moved outwards. Undo the locking screws on the movable stop rails and pull the rails back so far that a collision with the saw blade can be ruled out. Prior to every cut retighten the locking screws of the stop rails.
For miter cuts and double miter cuts with the saw head tilted to the right, the right stop rail must be removed completely. Important! In this case the maximum permissible workpie-ce height is reduced (see 4. Technical data).
Always fasten the movable stop rails back to the equipment again after you have comple-ted your work.
The stop rails must always remain together with the equipment. A removed stop rail will impair the operational safety of the equip-ment.
