Safety Hints

For your own safety, please refer to the enclosed safety instructions.

IMPORTANT SAFETY INSTRUCTIONS FOR CHARGER & BATTERY CARTRIDGE

ENC004-1

1.Before using battery cartridge, read all 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.Always cover the battery terminals with the battery cover when the battery cartridge is not used.

6.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.

7.Do not store the tool and battery cartridge in locations where the temperature may reach or exceed 50°C (122°F).

8.Do not incinerate the battery cartridge even if it is severely damaged or is completely worn out. The battery cartridge can explode in a fire.

9.Be careful not to drop or strike battery.

SAVE THESE INSTRUCTIONS.

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°C – 40°C (50°F – 104°F). Let a hot battery cartridge cool down before charging it.

4.Charge the Nickel Metal Hydride battery cartridge when you do not use it for more than six months.

ADDITIONAL SAFETY RULES FOR TOOL

ENB025-1

1.Be aware that this tool is always in an operating condition, because it does not have to be plugged into an electrical outlet.

2.Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring. Contact with a “live” wire will also make exposed metal parts of the tool “live” and shock the operator.

3.Wear ear protectors.

4.Check the socket carefully for wear, cracks or damage before installation.

5.Hold the tool firmly.

6.Always be sure you have a firm footing.

7.Be sure no one is below when using the tool in high locations.

8.The proper fastening torque may differ depending upon the kind or size of the bolt. Check the torque with a torque wrench.

SAVE THESE INSTRUCTIONS.

OPERATING INSTRUCTIONS

Installing or removing battery cartridge (Fig. 1)

•Always switch off the tool before insertion or removal of the battery cartridge.

•To remove the battery cartridge, withdraw it from the tool while pressing the push buttons on both sides of the cartridge.

•To insert the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Always insert it all the way until it locks in place with a little click. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.

•Do not use force when inserting the battery cartridge. If the cartridge does not slide in easily, it is not being inserted correctly.

Selecting correct socket

Always use the correct size socket for bolts and nuts. An incorrect size socket will result in inaccurate and inconsistent fastening torque and/or damage to the bolt or nut.

Installing or removing socket (Fig. 2)

Important:

Always be sure that the tool is switched off and the battery cartridge is removed before installing or removing the socket.

Move the O-ring out of the groove in the socket and remove the pin from the socket. Fit the socket onto the anvil of the tool so that the hole in the socket is aligned with the hole in the anvil. Insert the pin through the hole in the socket and anvil. Then return the O-ring to the original position in the socket groove to retain the pin. To remove the socket, follow the installation procedures in reverse.

Switch action (Fig. 3)

CAUTION:

Before inserting the battery cartridge into the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.

To start the tool, simply pull the trigger. Tool speed is increased by increasing pressure on the trigger. Release the trigger to stop.

Reversing switch action (Fig. 4)

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.

This tool has a reversing switch to change the direction of rotation. Slide the reversing switch to the left for clockwise rotation or to the right for counterclockwise rotation.

Operation (Fig. 5 & 6)

The proper fastening torque may differ depending upon the kind or size of the bolt. The relation between fastening torque and fastening time is shown in the figures.

Hold the tool firmly and place the socket over the bolt or nut. Turn the tool on and fasten for the proper fastening time.

NOTE:

•Hold the tool pointed straight at the bolt or nut without applying excessive pressure on the tool.

•Excessive fastening torque may damage the bolt or nut. Before starting your job, always perform a test operation to verify the adequate fastening speed and time for your bolt or nut.

The fastening torque is affected by a wide variety of factors including the following. After fastening, always check the torque with a torque wrench.

1.When the battery cartridge is discharged almost completely, voltage will drop and the fastening torque will be reduced.

2.Socket

•Failure to use the correct size socket will cause a reduction in the fastening torque.

•A worn socket (wear on the hex end or square end) will cause a reduction in the fastening torque.

3.Bolt

•Even though the torque coefficient and the class of bolt are the same, the proper fastening torque will differ according to the diameter of the bolt.

•Even though the diameters of bolts are the same, the proper fastening torque will differ according to the torque coefficient, the class of bolt and the bolt length.

4.The use of the universal joint or the extension bar somewhat reduces the fastening force of the impact wrench. Compensate by fastening for a longer period of time.

5.Type of materials to be fastened, the manner of holding the tool and the tool speed will affect the torque.

CAUTION:

If the tool is operated continuously until the battery cartridge has discharged, allow the tool to rest for 15 minutes before proceeding with a fresh battery.

MAINTENANCE

CAUTION:

Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool.

To maintain product safety and reliability, repairs, maintenance or adjustment should be carried out by a Makita Authorized Service Center.
