IMPORTANT SAFETY 

INSTRUCTIONS FOR BATTERY 

CARTRIDGE

ENC004-1

1. Before using battery cartridge, read all instruc-

tions 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 explo-

sion.

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 bat-

tery cover when the battery cartridge is not used.

6. Do not short the battery cartridge:

(1)  Do not touch the terminals with any conduc-

tive 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 break-

down.

7. Do not store the tool and battery cartridge in loca-

tions 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.

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 tempera-

ture 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.

FUNCTIONAL DESCRIPTION 

CAUTION:

• Always be sure that the tool is switched off and the bat-

tery cartridge is removed before adjusting or checking 

function on the tool.

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, pull out the set plate 

on the tool and grasp both sides of the cartridge while 

withdrawing it from the tool.

• To insert the battery cartridge, align the tongue on the 

battery cartridge with the groove in the housing and slip 

it into place. Snap the set plate back into place. Be sure 

to close the set plate fully before using the tool to pre-

vent the battery cartridge from accidentally falling out of 

the tool.

• Do not use force when inserting the battery cartridge. If 

the cartridge does not slide in easily, it is not being 

inserted correctly.

Switch action (Fig. 2)

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 switch trigger. Tool speed 

is increased by increasing pressure on the switch trigger. 

Release the switch trigger to stop.

Reversing switch action (Fig. 3)

This tool has a reversing switch to change the direction of 

rotation. Slide the reversing switch to the right (appear “F” 

marking) for clockwise rotation or to the left (appear “R” 

marking) for counterclockwise rotation.

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.

Speed change (Fig. 4)

To change the speed, turn the speed change knob so that 

the arrow of the desired speed on the knob is aligned with 

the reference arrow on the tool body. If the speed change 

knob does not turn easily, switch on the tool and turn the 

knob again while the tool is running under no load. Be 

sure that the speed change knob is set to the correct posi-

tion before operation. Use the right speed for your job.

Adjusting the fastening torque (Fig. 5)

The fastening torque can be adjusted in 6 steps by turning 

the adjusting ring so that the pointer on the adjusting ring 

points to a number on the tool body. The fastening torque 

is minimum when the pointer points to the number 1 and 

maximum when it points to the   marking.

The clutch will slip at various torque levels when set at the 

number 1 to 5. The clutch is designed not to slip at the   

marking. 

Before actual operation, drive a trial screw into your mate-

rial or a piece of duplicate material to determine which 

torque level is required for a particular application.
