tightening fasteners

1. Lock the trigger switch by placing the direction-of-rotation selector in the OFF (centre) position. Select a 

hex socket (available separately) that matches the bolt or nut.

2. Mount the socket on the anvil, and grip the bolt or nut to be tightened with the hex socket.

3. holding the cordless impact wrench in line with the bolt or nut, press the trigger to impact the nut for 

several seconds.

4. If the nut is only loosely fitted to the bolt, the bolt may turn with the nut. In this case, stop impact on the 

nut and hold the bolt head with a hand wrench before restarting impact, or manually tighten the bolt and 
nut to prevent them from slipping.

tightening torque

The tightening torque depends on the duration of the impacting/tightening action.

The greatest tightening torque is achieved after approximately 3–5 seconds of impacting/tightening action. 
The torque build-up depends on the following factors:

1. hardness of the bolts/nuts.

2. Type of washer (disc washer, spring washer, seal).

3. hardness of the materials to be joined.

4. Lubricating effect at the surface of the junction.

For example:

• 

A relatively short interval of impacting/tightening action is required when joining metal to metal with a 
disc washer.

• 

A moderate interval of impacting/tightening action is required when joining metal to metal where a 
spring-ring washer, disc-spring washer, stud bolt, or bolt/nut with conical seats are used.

• 

A longer interval of impacting/tightening action is necessary to arrive at the maximum tightening torque 
when joining metal to wood or insulation material.

Loosening fasteners

1. With the proper impact socket securely mounted to the cordless impact wrench, slide the impact socket 

onto the bolt head.

2. Verify that the rotational direction is “reverse.”

3. hold the tool securely with both hands and squeeze the trigger switch. The tool will start to impact 

immediately.

4. Once the fastener has “broken loose” it will start to unthread. Be careful that you do not allow a fastener 

to spin freely once it is no longer engaged with the other threaded part, as it may be thrown out of the 
socket.

installing or removing bits 

(fig 7)

1. Lock the trigger switch by placing the direction-

of-rotation selector in the OFF (centre) position.

2. To install or remove a 1/2" hex adaptor (available 

separately), pull the back sleeve of the 1/2" 
hex adaptor forward and press the hex adaptor 
onto the square drive. Make sure that the steel 
retention ball engages into the hole on the square 
drive. To remove the hex adaptor, simply grip the 
back sleeve and pull it off.

3. To install the bit, pull the front sleeve forward, hold 

it in place, insert a 1/2" bit into the hexagonal chuck, and then release the sleeve. Check that the sleeve 
returns to its original position and the bit is securely held in place. To remove the bit, pull the front sleeve 
forward and pull the bit off.
