Makita SC130DRA Manuel D'instructions page 10

Replace the cutters in accordance with the following procedure. Use only Makita genuine cutters for the tool.
1. There are two cutters. Cutter A is to be installed on the cutter head, and cutter B on the cutter rod. Be sure to
install them in the correct respective position. Refer to the table below for the cutter sizes.
For Model
SC130DRA
SC161DW
SC190DW
2. To install the cutters, first remove the two hex socket head bolts holding the cutters on the cutter head and cutter
rod, respectively.
3. Wipe off any dirt or foreign matter from the cutter-mounting position on the cutter head and cutter rod.
4. Secure firmly cutter A on the cutter head and cutter B on the cutter rod, using their respective flat washers and
hex socket head bolts. Failure to tighten securely is extremely dangerous.
Installing balance stand (Fig. 8)
When using the balance stand on the tool, be sure not to
block the air vents.
Switch action (Fig. 9)
CAUTION:
Before inserting the battery cartridge into the tool, always
check to see that the switch trigger actuates properly and
returns to the "OFF" position when released.
To start the tool, simply pull the trigger. Tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop.
Cutting operation (Fig. 10, 11, 12, 13 and 14)
1. Place the steel rod (material to be cut) in the open-
ing so as to be at right angles to the cutters. Adjust
the stopper (adjusting hex bolt for SC190DW) in
terms of the steel rod size (diameter). When cutting
large size steel rods, position the stopper (adjusting
hex bolt) as shown in Fig. 11-1, 12-1. When cutting
small size steel rods, position the stopper (adjusting
hex bolt) as shown in Fig. 11-2, 12-2. The stopper
(adjusting hex bolt) keeps the steel rod at right
angles to the cutters during the cutting.
2. Keep the steel rod at the deepest position in
between the cutters as shown in Fig. 13-1. Never
keep it as shown in Fig. 13-2. If the steel rod is not
placed at the deepest position between the cutters, it
may ride up and cause a fragment or piece to fly up.
Besides this dangerous situation, the cutters may be
damaged. Always position the steel rod properly.
3. Pull the trigger. The cutter rod advances to cut off
the steel rod. Keep the trigger pulled until the steel
rod is completely cut off.

(four cutting edges)
4. Release the trigger, and the cutter rod will automati-
cally return to its initial position.
NOTE:
The cutter rod will not return to its initial position
even if you release the trigger until the cutter rod
advances all the way and stops. And until the cutter
rod completely return to its initial position, it will not
move forward again even if you pull the trigger. Pull
the trigger to begin the next cut-off only after the cut-
ter rod has completely returned to its initial position.
Return valve (Fig. 15)
For SC161DW and SC190DW
It may happen that the cutters will engage the steel rod
and come to a stop before the cut-off is completed. In
that case, use the hex wrench M4 to release the hydrau-
lic pressure in the return valve. Insert the hex wrench M4
into the return valve hole and make a half turn in the
counterclockwise direction. This releases the hydraulic
pressure inside the tool, allowing the cutter rod to return
to its initial position. Always retighten the valve before
doing the next cut-off job.
Angling into tight places
For SC161DW and SC190DW
One useful feature is that you can, even after beginning a
cut-off (load condition), rotate the tool by the handle 360°
left or right. This makes work in tight places easier, espe-
cially trigger access and activation. You can even swing
the tool while pulling the trigger.
