12. Remove any adjusting key or wrench before  
turning the power tool on. A wrench or a key left  
attached to a rotating part of the power tool may  
result in personal injury.  
13. Do not overreach. Keep proper footing and bal-  
ance at all times. This enables better control of the  
power tool in unexpected situations.  
14. Dress properly. Do not wear loose clothing or  
jewellery. Keep your hair, clothing, and gloves  
away from moving parts. Loose clothes, jewellery  
or long hair can be caught in moving parts.  
15. 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.  
GENERAL SAFETY RULES  
WARNING! Read all instructions. Failure to follow all  
instructions listed below may result in electric shock, fire  
and/or serious injury. The term "power tool" in all of the  
warnings listed below refers to your mains-operated  
(corded) power tool or battery-operated (cordless) power  
tool.  
SAVE THESE INSTRUCTIONS.  
Work area safety  
1. Keep work area clean and well lit. Cluttered and  
dark areas invite accidents.  
2. Do not operate power tools in explosive atmo-  
spheres, such as in the presence of flammable  
liquids, gases or dust. Power tools create sparks  
which may ignite the dust or fumes.  
3. Keep children and bystanders away while oper-  
ating a power tool. Distractions can cause you to  
lose control.  
Power tool use and care  
16. Do not force the power tool. Use the correct  
power tool for your application. The correct power  
tool will do the job better and safer at the rate for  
which it was designed.  
17. Do not use the power tool if the switch does not  
turn it on and off. Any power tool that cannot be  
controlled with the switch is dangerous and must be  
repaired.  
18. Disconnect the plug from the power source and/  
or the battery pack from the power tool before  
making any adjustments, changing accessories,  
or storing power tools. Such preventive safety  
measures reduce the risk of starting the power tool  
accidentally.  
19. Store idle power tools out of the reach of chil-  
dren and do not allow persons unfamiliar with  
the power tool or these instructions to operate  
the power tool. Power tools are dangerous in the  
hands of untrained users.  
20. Maintain power tools. Check for misalignment or  
binding of moving parts, breakage of parts and  
any other condition that may affect the power  
tools operation. If damaged, have the power tool  
repaired before use. Many accidents are caused by  
poorly maintained power tools.  
21. Keep cutting tools sharp and clean. Properly  
maintained cutting tools with sharp cutting edges  
are less likely to bind and are easier to control.  
22. Use the power tool, accessories and tool bits  
etc. in accordance with these instructions and in  
the manner intended for the particular type of  
power tool, taking into account the working con-  
ditions and the work to be performed. Use of the  
power tool for operations different from those  
intended could result in a hazardous situation.  
Electrical safety  
4. 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.  
5. 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.  
6. Do not expose power tools to rain or wet condi-  
tions. Water entering a power tool will increase the  
risk of electric shock.  
7. 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.  
8. 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  
9. 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.  
10. Use safety equipment. Always wear eye protec-  
tion. Safety equipment such as dust mask, non-skid  
safety shoes, hard hat, or hearing protection used  
for appropriate conditions will reduce personal inju-  
ries.  
11. Avoid accidental starting. Ensure the switch is in  
the off-position before plugging in. Carrying  
power tools with your finger on the switch or plug-  
ging in power tools that have the switch on invites  
accidents.  
Service  
23. Have your power tool serviced by a qualified  
repair person using only identical replacement  
parts. This will ensure that the safety of the power  
tool is maintained.  
24. Follow instruction for lubricating and changing  
accessories.

25. Keep handles dry, clean and free from oil and  
grease.  
Switch action (Fig. 5)  
CAUTION:  
Before plugging in the tool, always check to see that the  
switch trigger actuates properly and returns to the “OFF”  
position when released.  
SPECIFIC SAFETY RULES  
GEB017-1  
DO NOT let comfort or familiarity with product  
(gained from repeated use) replace strict  
adherence to screwdriver safety rules. If you use  
this tool unsafely or incorrectly, you can suffer  
serious personal injury.  
1. Hold power tools 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. Always be sure you have a firm footing. Be sure  
no one is below when using the tool in high loca-  
tions.  
To start the tool, simply pull the trigger.tool speed is  
increased by increasing pressure on the trigger. Release  
the trigger to stop. For continuous operation, pull the trig-  
ger and then push in the lock button. To stop the tool from  
the locked position, pull the trigger fully, then release it. A  
speed control screw is provided so that maximum tool  
speed can be limited (variable). Turn the speed control  
screw clockwise for higher speed, and counterclockwise  
for lower speed.  
NOTE:  
Even with the switch on and motor running, the bit will not  
rotate until you fit the point of the bit in the screw head  
and apply forward pressure to engage the clutch.  
3. Hold the tool firmly.  
Reversing switch action (Fig. 6)  
4. Keep hands away from rotating parts.  
5. Do not touch the bit or the workpiece immedi-  
ately after operation; they may be extremely hot  
and could burn your skin.  
CAUTION:  
• Always check the direction of rotation before operation.  
• Use the reversing switch only after the tool comes to a  
complete stop. Changing the direction of rotation  
before the tool stops may damage the tool.  
SAVE THESE INSTRUCTIONS.  
This tool has a reversing switch to change the direction of  
rotation. Move the reversing switch lever to the “FWD”  
position for clockwise rotation or the “REV” position for  
counterclockwise rotation.  
WARNING:  
MISUSE or failure to follow the safety rules stated  
in this instruction manual may cause serious per-  
sonal injury.  
Operation (Fig. 7)  
OPERATING INSTRUCTIONS  
Fit the screw on the point of the bit and place the point of  
the screw on the surface of the workpiece to be fastened.  
Apply pressure to the tool and start it. Withdraw the tool  
as soon as the screw bottoms out.  
Removing or installing the bit (Fig. 1)  
Important:  
Always be sure that the tool is switched off and  
unplugged before removing or installing the bit.  
CAUTION:  
• Use the proper bit for the head of the screw that you  
wish to use.  
• When fitting the screw onto the point of the bit, be care-  
ful not to push in on the screw. If the screw is pushed  
in, the clutch will engage and the screw will rotate sud-  
denly. This could damage a workpiece or cause an  
injury.  
To remove the bit, first pull the stopper out of the locator.  
Then grasp the bit with a pair of pliers and pull the bit out  
of the magnetic bit holder. Sometimes, it helps to wiggle  
the bit with the pliers as you pull. To install the bit, push  
the bit firmly into the magnetic bit holder. Then install the  
stopper by pushing it firmly into the locator.  
NOTE:  
Depth adjustment (Fig. 2, 3 & 4)  
Push the locking sleeve in toward the motor and turn  
slightly clockwise to lock it.  
Make sure that the bit is inserted straight in the screw  
head, or the screw and/or bit may be damaged.  
Turn the locator to adjust the depth. Initially, adjust the  
locator so that the tip of the locator is flush with the base  
of the screw head. One full turn of the locator equals 1.5  
mm change in depth. After adjusting the locator, unlock  
the locking sleeve. Turn the locking sleeve slightly so that  
the protrusions on the locking sleeve engage in the  
notches in the locator. Drive a trial screw into your mate-  
rial or a piece of duplicate material. If the depth is not  
suitable for the screw, continue adjusting until the proper  
depth setting is obtained.  
MAINTENANCE  
CAUTION:  
Always be sure that the tool is switched off and  
unplugged before carrying out any work on the tool.  
To maintain product safety and reliability, repairs, mainte-  
nance or adjustment should be carried out by a Makita  
Authorized Service Center.  
NOTE:  
Before starting your job, always test-drive a sample  
screw into a piece of the installation workpiece so that  
you are sure to have the right depth and desired adjust-  
ment.
