SPECIFIC SAFETY RULES 
DO NOT let comfort or familiarity with product 
(gained from repeated use) replace strict adherence 
to impact driver safety rules. If you use this tool 
unsafely or incorrectly, you can suffer serious 
personal injury. 
1. 
Hold power tool by insulated gripping 
surfaces, when performing an operation 
where the fastener may contact hidden wiring 
or its own cord.
 Fasteners contacting a "live" 
wire may make exposed metal parts of the power 
tool "live" and could give the operator an electric 
shock.

Be sure no one is below when using the tool in 
high locations. 
3. Hold the tool firmly.

instructions and cautionary markings on (1) 
battery charger, (2) battery, and (3) product 
using battery. 
2. Do not disassemble battery cartridge. 
3. If operating time has become excessively 
shorter, stop operating immediately. It may 
result in a risk of overheating, possible burns 
and even an explosion. 
4. If electrolyte gets into your eyes, rinse them 
out with clear water and seek medical 
attention right away. It may result in loss of 
your eyesight. 
5. Do not short the battery cartridge: 
(1) Do not touch the terminals with any 
conductive 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 breakdown. 
6. Do not store the tool and battery cartridge in 
locations where the temperature may reach or 
exceed 50 ゚C (122 ゚F). 
7. 
Do not incinerate the battery cartridge even if

Tips for maintaining maximum battery life 
1. Charge the battery cartridge before completely 
discharged. 
Always stop tool operation and charge the 
battery 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 
temperature at 10 ゚C - 40 ゚C (50 ゚F - 104 ゚F). 
Let a hot battery cartridge cool down before 
charging it.
