tighten both screws to lock into position. (See G)

8. ROLLER GUIDE

Ensure the blade 

is located and 

runs smoothly in 

the groove. (See 

F) Otherwise the 

pendulum function 

will not work 

correctly and the 

blade will not be supported during cutting.

9. PENDULUM 

ACTION 

CONTROL

The pendulum 

action varies the 

forward cutting 

angle of the blade 

for increased 

cutting efficiency. This can also be adjusted 

during no load running. Refer to the chart 2 for 

more details. Do not use excessive blade force 

when cutting with the pendulum action. The 

blade cuts on the upward stroke only (See H).

Chart 2

0

Thin materials. Fine cuts. Tight curves.

1

Hard materials, (e.g. steel & chipboard)

2

Thick materials (e.g. wood) & plastic

3

Fast cuts (e.g. softwood). Cutting in the 

direction of the wood grain.

10. ANGLE PLATE

Adjusting the angle of the base plate enables 

bevel cutting. The base plate must always be held 

firmly against the materials being cut to reduce 

saw vibration, blade jumping or blade breakage.

11. PLASTIC 

FOOT PLATE 

PROTECTION 

(See I)

Your tool is 

equipped with 

base plate 

protection that protects finer surface.

To attached, hook the protection over front of 

base plate and snap into base plate.

12. BASE PLATE ANGLE ADJUSTMENT (See 

J, K)

Use a hex key (3). First loosen the bolts securing 

the base plate 

and pull the base 

plate out of the 

slots (See J). For 

preset angles 

rotate so the lines 

of the angle on 

the base plate 

and angle plate 

(9) superposition 

at the desired 

angle (0, 15, 30, 

45) (See K). For 

other bevel angles, 

rotate to your 

desired angle (use 

a protractor scale). Following one of the above 

procedures, hold the base plate in position and 

firmly tighten the bolts to clamp the base plate at 

that angle. Finally, check the angle and ensure 

the base plate is firmly clamped. The angle 

markings on the base plate are accurate for 

most general purposes but it is recommended for 

accurate work to 

set the angle with 

a protractor and 

make a test cut on 

other material.

13. VACUUM 

ADAPTER 

The adapter (22) rotates anti-clockwise inside the 

housing and locks in position by a groove inside 

the housing (See L). The adapter must then be 

connected to a suitable external dust extraction 

machine. 

14. PROTECTION FINGER

The finger is located in front of the blade holder. 

Whilst working, it will help prevent accidental 

contact with moving blade.

15. DUST BLOWER SWITCH (See M)

The sawdust blower device leads an air jet to the 

saw blade. The air 

jet avoids sawdust 

from covering the 

cutting line during 

operation. 

The sawdust 

vacuum device can
