GENERAL POWER TOOL SAFETY WARNINGS
WARNING
Read all safety warnings, instructions, illustrations and specifications provided with this power tool.
Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated
(cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust.
Power tools create sparks which may ignite the
dust or fumes.
c) Keep children and bystanders away while
operating a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with earthed
(grounded) power tools.
Unmodified plugs and matching outlets will
reduce risk of electric shock.
b) Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges
and refrigerators.
There is an increased risk of electric shock if your
body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions.
Water entering a power tool will increase the risk
of electric shock.
d) Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the power
tool.
Keep cord away from heat, oil, sharp edges
or moving parts.
Damaged or entangled cords increase the risk of
electric shock.
e) When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the

charger after use, and then keep it.
Regarding electric discharge in case of new
batteries, etc.
As the internal chemical substance of new batteries
and batteries that have not been used for an extended
period is not activated, the electric discharge might
be low when using them the first and second time.
This is a temporary phenomenon, and normal time
required for recharging will be restored by recharging
the batteries 2–3 times.
How to make the batteries perform longer
(1) Recharge the batteries before they become
completely exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the
battery and recharge it after it has cooled for a while.

● When the battery charger has been continuously
used, the battery charger will be heated, thus
constituting the cause of the failures. Once the
charging has been completed, give 15 minutes
rest until the next charging.
● If the battery is charged while it is heated
because it has been left for a long time in a
location subject to direct sunlight or because
the battery has just been used, the pilot lamp of
the charger lights for 1 second, does not light for
0.5 seconds (offfor 0.5 seconds).
The battery will not be recharged. In such a
case, let the battery cool before charging.
● When the pilot lamp flickers (at 0.2-second
intervals), check for and take out any foreign
objects in the charger’s battery connector. If
there are no foreign objects, it is probable that
the battery or charger is malfunctioning. Take it
to your authorized Service Center.

Fig. 17
2. Stroke Mode
This power tool features a straight mode in which the
blade moves back and forth, and an orbital mode in
which the blade moves back and forth while moving
up and down.
For soft materials such as wood, orbital mode
ensures smooth cutting operation while improving the
discharge of sawdust and the interlock with materials.
Use the change lever to select the ideal mode for the
task at hand. (Fig. 18)
The ideal mode depends on factors such as the
hardness of the material to be cut and the level of
finish required. Use Table 5 as a guideline when
making your choice.
