BATTERY CHARGING
IMPORTANT
Connect the power core to the DC terminal at bottom of 
the battery first, and then plug the compact transformer 
into the A.C. power outlet.
It takes approximately 1~1.5 hours to get fully charged 
battery.

RECHANGABLE BATTERY POWER 
TOOL USE AND CARE
• Ensure the lock switch is in « off « position 
before inserting battery pack.
• Use only original manufacturer supplied 
charger to charge original manufactured 
battery.
• Use of any other battery packs may cause 
damage or fire.
• When battery pack is not in use, keep it 
away from other metal objects like paper clips, 
coins, keys, nails, screws or other small metal 
objects that can make a connection from 
one terminal to another. Shorting the battery 
terminals may cause burns or a fire.
• Under abusive conditions, liquid may be 
ejected from the battery, please avoid contact. 
If contact accidentally occurs, flush and clean 
with water. If liquid contacts eyes, look for 
medical help immediately. Liquid ejected from 
the battery may cause irritation or burns.
• If the performance of the battery diminishes 
substantially even it has been fully charged, 
the life of battery is terminated, please replace 
a new one.
• Do not keep the battery in recharge for more 
than 2 hours. This could reduce battery life.
• Wet or overheat condition will reduce 
battery life.
• When discarding batteries, environmental 
issues must be considered. The local rules or 
laws governing the disposal of battery must 
be followed strictly.
Maintaining battery pack
The battery packs will operate for years and/or 
hundreds of cycles when they are maintained 
and used according to these instructions.
• A battery pack that is stored for six months 
without using will discharge itself. Batteries 
discharge at a rate of about 1% per day. 
Charge the battery every six months even it is 
unused to maximize battery life. Replace this 
battery pack until it no longer performs the 
power needed for your application.
• Store your battery pack in a cool, dry place. 
Do not store at place where the temperature 
may exceed 50°C such as in a vehicle or metal 
storage during the summer. High temperature 
will overheat the battery pack, and reduce 
battery life. If it is stored for several months, 
the battery pack will gradually lose its power. 
During the life of the battery pack, the 
operating time between charges becomes 
shorter. If the operating time becomes 
extremely short after a proper charge, the life 
of the battery pack has been terminated and it 
should be replaced.
GENERAL SAFETY RULES
Work area safety
Keep work area clean and well lit. Cluttered or 
dark areas cause accidents easily.
• Do not operate power tool 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.
• Keep children and bystanders away while 
operating a power tool. Distractions can cause 
you to lose control.
Electrical safety
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. Correct plugs and matching outlets will 
reduce risk of electric shock.
• Avoid body contact with grounded 
surfaces such as pipes, radiators, ranges 
and refrigerators. There is an increased risk of 
electric shock if your body is grounded.
• Do not expose power tools to rain or wet 
conditions. Water entering a power tool will 
increase the risk of electric shock.
• 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.
• When operating a power tool outdoors, use 
an extension cord suitable for outdoor use. 
Use of a cord suitable for outdoor use reduces 
the risk of electric shock.
Personal safety
• Stay alert, watch what you are doing and 
use common sense when operating a power 
tool. Do not use a power tool while you are 
tired or under the influence of drugs, alcohol 
or medication. A moment of inattention while 
operating power tools may result in serious 
personal injury.
• Use safety equipment. Always wear eye 
protection. Safety equipment such as dust 
mask, non-skid safety shoes, hard hat or 
hearing protection used for appropriate 
conditions will reduce personal injuries.
• Avoid accidental starting. Ensure the switch 
is in the off-position before plugging in. 
Carrying tools with your finger on the switch 
or plugging in power tool that have the switch 
on invites accidents.
• Do not overreach. Keep proper footing and 
balance at all times. This enables better control 
of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing 
or jewelry. Keep your hair, clothing and gloves 
away from moving parts. Loose clothes, 
jewelry or long hair can be caught in moving 
parts.
• If devices are provided for the connection of 
dust extraction and collection facilities, ensure 
these are connected and properly used. Use 
of these devices can reduce dust-related 
hazards. 
• Working at high place with this caulking gun, 
please notice working environment safety.
WARNING
Never remove the plunger rod off the tool in 
any case, otherwise it will cause failure of 
spheres locating which makes the gun fail to 
work. Keep the plunger rod clear and neat at 
all times. A plunger rod covered with adhesive 
may damage the whole mechanism. The 
warranty expires when adhesive goes into the 
mechanism; in addition, any maintenance fee 
occurred will be charged by the repair service 
facility. 
In case of that residual material left on the 
plunger rod, please clean it up thoroughly 
before pulling the rod to the backward 
position. The purpose is to prevent the 
material from entering the inner mechanism 
and keeping the tool in good condition.
