8. DANGER:
Keep Hands Away From Cutting Area.
Keep hands away from blades. Don't reach
underneath work while blade is rotating. Don't
attempt to remove cut material when blade is
moving.
CAUTION: Blades coast after turn off.
9. Support Large Panels. (Fig. 1 & 2)
Large panels must be supported as shown in
Fig. 1 to minimize the risk of blade pinching and
kickback.
When cutting operation requires the resting of
the saw on the workpiece, the saw shall be
rested on the larger portion and the smaller
piece cut off.
10. Use Rip Fence.
Always use a fence or straight edge guide when
ripping.
11. Guard Against Kickback. (Fig. 1 & 3)
Kickback occurs when the saw stalls rapidly and
is driven back towards the operator. Release
switch immediately if blade binds or saw stalls.
Keep blades sharp. Support large panels as
shown in Fig. 1.
Use fence or straight edge guide when ripping.
Don't force tool. Stay alert – exercise control.
Don't remove saw from work during a cut while
the blade is moving.
NEVER place your hand or fingers behind the
saw. If kickback occurs, the saw could easily
jump backwards over your hand, possibly caus-
ing severe injury.
12. Lower Guard.
Raise lower guard with the retracting handle.
13. Adjustments.
Before cutting be sure depth and bevel adjust-
ments are tight.
14. Use Only Correct Blades In Mounting.
Don't use blades with incorrect size holes. Never
use defective or incorrect blade washers or
bolts.
15. Avoid Cutting Nails.
Inspect for and remove all nails from lumber
before cutting.
16. Operate with proper hand support and proper
workpiece support.
WARNING:
It is important to support the workpiece properly
and to hold the saw firmly to prevent loss of con-
trol which could cause personal injury. Fig. 4
illustrates typical hand support of the saw.
17. Place the wider portion of the saw base on that
part of the workpiece which is solidly supported,
not on the section that will fall off when the cut is
made.
As example, Fig. 5 illustrates the RIGHT way to
cut off the end of a board, and Fig. 6 the WRONG
way. If the workpiece is short or small, clamp it
down. DON'T TRY TO HOLD SHORT PIECES BY
HAND! (Fig. 6)
18. Never attempt to saw with the circular saw held
upside down in a vise. This is extremely danger-
ous and can lead to serious accidents. (Fig. 7)
19. Before setting the tool down after completing a
cut, be sure that the lower (telescoping) guard
has closed and the blade has come to a com-
plete stop.
20. Using manufacturer data
• Ensure that the diameter, thickness and other
characteristics of the saw blade are suitable for
the tool.
• Ensure that the saw blade is suitable for the
spindle speed of the tool.
21. Do not use any abrasive wheel.

OPERATING INSTRUCTIONS
Installing or removing battery cartridge (Fig. 8)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while sliding the button on the side of the cartridge.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If you can see the red part on
the upper side of the button, it is not locked completely.
Insert it fully until the red part cannot be seen. If not, it
may accidentally fall out of the tool, causing injury to
you or someone around you.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Removing or installing saw blade
Important:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before removing or installing
the blade.
The following blade can be used with this tool.
Max. dia. Min. dia.
190 mm 170 mm
The thickness of the riving knife is 1.8 mm.
CAUTION:
• Do not use saw blades which do not comply with the
characteristics specified in these instructions.
• Do not use saw blades the disc of which is thicker or
the set of which is smaller than the thickness of the riv-

To remove the blade, press the shaft lock so that the
blade cannot revolve and use the hex wrench to loosen
the bolt counterclockwise. Then remove the bolt, outer
flange and blade. (Fig. 9)
To install the blade, follow the removal procedure in
