Additional Safety Rules For Tool - Makita BLS820 Instruction Manual

5. Do not short the battery cartridge:
(1) Do not touch the terminals with any conduc-
tive material.
(2) Avoid storing battery cartridge in a container
with other metal objects such as nails, coins,
etc.
(3) Do not expose battery cartridge to water or
rain.
A battery short can cause a large current flow,
overheating, possible burns and even a break-
down.
6. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50°C (122°F).
7. Do not incinerate the battery cartridge even if it
is severely damaged or is completely worn out.
The battery cartridge can explode in a fire.
8. Be careful not to drop or strike battery.
SAVE THESE INSTRUCTIONS.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the bat-
tery cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room tempera-
ture at 10°C – 40°C (50°F – 104°F). Let a hot bat-
tery cartridge cool down before charging it.
4. Charge the Nickel Metal Hydride battery car-
tridge when you do not use it for more than six
months.

ADDITIONAL SAFETY RULES FOR TOOL

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 eye protection.
3. Keep hands out of path of saw blade. Avoid con-
tact with any coasting blade. It can still cause
severe injury.
4. Do not operate saw without guards in place.
Check blade guard for proper closing before
each use. Do not operate saw if blade guard
does not move freely and close instantly. Never
clamp or tie the blade guard into the open posi-
tion.
5. Do not perform any operation freehand. The
workpiece must be secured firmly against the
turn base and guide fence with the vise during
all operations. Never use your hand to secure
the workpiece.
6. Never reach around saw blade.
7. Turn off tool and wait for saw blade to stop
before moving workpiece or changing settings.
8. Remove battery from tool before chaging blade
or servicing.
9. Don't use the tool in the presence of flammable
liquids or gases.
10. Check the blade carefully for cracks or damage
before operation. Replace cracked or damaged
blade immediately.
11. Use only flanges specified for this tool.
12. Be careful not to damage the arbor, flanges (espe-
cially the installing surface) or bolt. Damage to
these parts could result in blade breakage.
13. Make sure that the turn base is properly secured
so it will not move during operation.
14. For your safety, remove the chips, small pieces,
etc. from the table top before operation.
15. Avoid cutting nails. Inspect for and remove all
nails from the workpiece before operation.
16. Make sure the shaft lock is released before the
switch is turned on.
17. Be sure that the blade does not contact the turn
base in the lowest position.
18. Hold the handle firmly. Be aware that the saw
moves up or down slightly during start-up and
stopping.
19. Make sure the blade is not contacting the work-
piece before the switch is turned on.
20. Before using the tool on an actual workpiece, let
it run for a while. Watch for vibration or wobbling
that could indicate poor installation or a poorly
balanced blade.
21. Wait until the blade attains full speed before cut-
ting.
22. Stop operation immediately if you notice any-
thing abnormal.
23. Do not attempt to lock the trigger in the on posi-
tion.
24. Be alert at all times, especially during repetitive,
monotonous operations. Don't be lulled into a
false sense of security. Blades are extremely
unforgiving.
25. Always use accessories recommended in this
manual. Use of improper accessories such as
abrasive wheels may cause an injury.
26. Do not use the saw to cut other than wood or
similar materials.
ENB041-3
27. Connect miter saws to a dust collecting device
when sawing.
28. Select saw blades in relation to the material to be
cut.
29. Take care when slotting.
30. Replace the kerf board when worn.
Do not use saw blades manufactured from high speed
steel.
Some dust created from operation contains chemicals
known to cause cancer, birth defects or other reproduc-
tive harm. Some examples of these chemicals are:
• lead from lead-based-painted material and,
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how
often you do this type of work.
To reduce your exposure to these chemicals: work in a
well ventilated area and work with approved safety equip-
ment, such as those dust masks that are specially
designed to filter out microscopic particles.
To reduce the emitted noise, always be sure that the
blade is sharp and clean.
The operator is adequately trained in the use, adjustment
and operation of the machine.
Use correctly sharpened saw blades. Observe the maxi-
mum speed marked on the saw blade.
Refrain from removing any cut-offs or other parts of the
workpiece from the cutting area whilst the machine is
running and the saw head is not in the rest position.
