PUTTING INTO OPERATION

 CAUTION:

Always turn off the engine and pull off the spark plug cap 

before doing any work on the Power Cutter! Always wear 

protective gloves!

 CAUTION:

Start the Power Cutter only after complete assembly and 

inspection.

Mounting the cutting disc

 WARNING:

When installing a diamond cutting disc, be sure to mount 

• 

it so that the arrow is in the same direction as the outer 

flange (6) rotates.

 Mounting the diamond cutting disc 

(4)

 with 

its arrow direction opposite to that on the wheel cover may 

cause chipping of the disc edge and personal injury.

When installing a cutting disc (4), always use the ring that 

• 

matches the bore of the cutting disc and the diameter of 

the spindle (5).

 Failure to use rings that mate may cause tool 

vibration resulting in serious personal injury.

Only use cutting discs with the bore that matches the 

• 

diameter of the ring(s) provided.

 Using discs that do not mate 

may cause tool vibration resulting in serious personal injury.

Inspect a cutting disc for damage. (see the section titled 

• 

“Cutoff discs” in SAFETY PRECAUTIONS.)

1.   Insert the star-shaped wrench 

(2)

 into the hole 

(8)

 to prevent 

the spindle 

(5)

 from rotating.

NOTE

:   When the holder of the pressure water system is installed 

in the hole in the tool, remove it before mounting the 

cutting disc.

2.   While holding on the wrench 

(2)

 in that position, use the 

combination wrench 

(1)

 provided and turn the bolt 

(7)

 securing 

the disc counterclockwise and remove the bolt 

(7)

 and outer 

flange 

(6)

.

3.   Mount a diamond cutting disc/cut-off abrasive disc 

(4)

 on the 

arbor 

(5)

. And then put the outer flange 

(6)

 on the spindle 

so that the two parallel flat surface on the outer flange fit the 

spindle flat surface and firmly tighten the bolt clockwise.

To install a cutting disc, mount a ring with the same matching 

diameter as the disc bore and the O ring provided to retain the 

ring on the spindle before installing a diamond cutting disc.

And then install the cutting disc.

NOTE

:   Tighten the hex bolt firmly (25 - 31 Nm), as otherwise the 

cutting wheel may slip during cutting.

For the following work, use the assembly tools included with 

delivery:

1.  13/16 AF combination wrench

2.  Star-sharped wrench

3.  Carburetor adjustment screwdriver

4.  Adapter ring

Place the Power Cutter on a stable surface and carry out the 

following assembly steps:

 No air filter is installed!

Before operation, squeeze the supplied filter several times so 

that oil is evenly immersed in the entire filter. Insert an oiled 

foam filter (pre-filter), as shown in the adjacent illustration! To 

do this, take off the filter cover (see the chapter on Cleaning/

changing the air filter).
