6. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50°C (122°F).

ADDITIONAL SAFETY RULES FOR TOOL
ENB037-2
1. Be aware that this tool is always in an operating
condition, because it does not have to be
plugged into an electrical outlet.
2. Wear hearing protection.
3. Keep Guards In Place and In Working Order.
Never wedge or tie lower guard open. Check
operation of lower guard before each use. Don’t
use if lower guard does not close briskly over
saw blade.
CAUTION: If saw is dropped, lower guard may be
bent, restricting full return.
4. Do not use blades which are deformed or
cracked.
5. Do not use blades of high speed steel.
6. Do not stop the blades by lateral pressure on the
saw blade.
7. Keep Blades Clean and Sharp.
Sharp blades minimize stalling and kickback.
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 pressing the push buttons on both sides 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 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.
