1. GENERAL SAFETY RULES
WARNING! Read and understand all instructions. Failure to follow all instructions listed below may
result in electric shock, fire and/or serious personal injury
SAVE THESE INSTRUCTIONS
1.1 Work Area
- Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
- 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.
- Keep bystanders, children, and visitors away while operating a power tool. Distractions can
cause you to lose control.
1.2 Electrical Safety
- Grounded tools must be plugged into an outlet properly installed and grounded in accordance
with all codes and ordinances. Never remove the grounding prong or modify the plug in any
way. Do not use any plugs. Check with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools should electrically malfunction or break down, grounding
provides a low resistance path to carry electricity away from the user.
- Avoid body contact with grounded surface ad pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is grounded.
- Don't 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 to carry the tools or pull the plug from an outlet.
Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords
immediately. Damaged cords increase the risk of electric shock.
- When operating a power tool outside, use an outdoor extension cord marked W-A or W.
These cords are rated for outdoor use and reduce the risk of electric shock.
1.3 Personal Safety
- Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of
inflation while operating power tools may result in serious personal injury.
- Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair,
clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in
moving parts.
- Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your finger
on the switch or plugging in tools may result in personal injury.
- Remove adjusting keys or switches before turning the tool on. A wrench or a key that is left
attached to a rotating part of the tool may result in personal injury.
- Do not overreach. Keep proper footing and balance at all times. Proper footing and balance
enables better control of the tool in unexpected situations.
- Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat,
or hearing protection must be used for appropriate conditions.
1.4 Tool use and Care
- Use clamps or other practical way to secure and support the workplace to a stable platform.
Holding the work by hand or against your body is unstable and may lead to loss of control.
- Do not force tool. Use the correct tool for your application. The correct tool will do the job better
and safer at the rate for which it is designed.
- Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the
switch is dangerous and must be repaired.
- Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing the tool. Such preventive safety

Instructions manual / GX-H & GXA-H 40 Volts Screwdrivers
5
- Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the
hands of untrained users.
-Maintain toolswith care. Keep cuttingtools sharp and clean. Properlymaintained tools, with sharp
cutting edges are less likely to bind and are easier to control.
- Check for misalignment or binding of moving parts, breakage of parts, and any other condition
that may affect the tools operation. If damaged, have the tool serviced before using. Many
accidents are caused by poorly maintained tools.
- Use only accessories that are recommended by the manufacturer for your model. Accessories
that may be suitable for one tool, may become hazardous when used on another tool.
1.5 SERVICE
- Tool service must be performed only by qualified personnel. Service or maintenance performed
by unqualified personnel could result in a risk of injury
- When servicing a tool, use only identical replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance
instructions may create a risk of electric shock or injury.
2. SPECIFIC SAFETY RULES
2.1 Hold tool by insulated gripping surfaces when performing an operation where the
cutting tool may contact hidden wiring or its own cord.
Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator.
2.2 Never lubricate aerosol oil on to the electrical part.

Concerns feature of out signals : run and torque up
- Complete Motor Run Signal Out During One Cycle
If the user set 1st run-stop-reverse turn as a complete cycle, motor run signal will last for a cycle.
In the same way, if just 1st run is set, motor run signal comes out just once.
- One Torque-up Count for One Complete T Cycle with SCOUTII
1st and 2nd run are either torque or angle control
Torque up signal means complete cycle Ok
