The battery is equipped with LED indicators that
indicate the remaining battery life at any time by
pressing the adjacent button (C):
4 LEDs illuminated: fully charged
2 LEDs illuminated: 50 % capacity
1 LED flashing: minimum charge, the battery is
almost depleted and needs to be charged.
The electronics protect the battery from any damage
caused by complete depletion.
Continuous overload causes deactivation due to overheating. In such a case, allow the battery to cool down;
if the battery feels hot to the touch, it can be cooled down more quickly by inserting it into the relevant“AIR
COOLED”battery charger.
The battery charge status can also be seen on the display (11).
5.2) Using the battery charger
Only use the battery charger supplied following the instructions provided.
6.1) Assembly/disassembly of sockets (Ref. to Fig. 5)
Always remove the battery when fitting or removing any accessories.
Any accessory (extension, adapter, joint, socket) must be specified for use with impact
tools.The use of unsuitable accessories could lead to breakage.
Before use, always check to make sure the socket shows no signs of breakage or particular
wear. If the socket does not fit tightly on the square shaft this could result in a loss of
power and excessive wear of components.
Sockets are optional accessories that can be supplied separately.
Choose the appropriate socket for the fixing element you intend to work on:
- square, hexagonal, double square etc.
- suitable socket and length.
- Specified for impact tooling.
- Assemble on to 25.4 mm (1”) square shaft with through bore.
Slide the socket onto the square shaft (8) lining up the bores of the socket and the shaft (Ref. to Fig. 5a).
Fully insert the supplied CLIP-NR circlip into the through bore, ensuring the spring arms are correctly
located in the slot around the socket.
To disassemble the socket, extract CLIP-NR by simultaneous lateral pushing on both ends of the circlip
arms (Ref. to Fig. 5b) then recover the ejected CLIP-NR.
If necessary, it is possible to insert an extension between the socket and the wrench to adapt to various
usage needs.

6.2) Inserting/removing the batteries
The impact wrench is designed to work ONLY with both batteries inserted.The diagnostic system constantly
checks both batteries and halts the operation of the machine when the voltage of one of the batteries falls
below a predetermined threshold.
To insert the batteries (Ref. to Fig. 6):
Lift the rainproof cover (3) to access the battery compartment.
Insert the batteries into the guides and press them all the way down until they latch (G) into place.
Close the cover (3) tightly.
To remove the batteries:
Press the button (P) and slide them out from the top.
After removing or inserting batteries, be sure to replace the rainproof cover. Make sure the
cover fits sideways and covers the battery compartment properly. Improper placement of the
rainproof cover can cause water ingress, resulting in damage to electrical components, motor
and batteries.
6.3) Torque adjustment
The wrench is equipped with a system which allows torque limitation on tightening
and loosening according to the different needs of use.
Press the ON/OFF button (12) to power up the wrench.
Push and turn the selector (10) in one direction or the other to obtain the desired
value on the display. It is advisable to set:
- the tightening phase on low torque settings: 1 - 2 - 3.
- the loosening phase on high torque settings: 3 - 4 - 5.
Press the selector (10) to confirm the choice.
6.4) Setting the rotation direction
Press the button (13) to select the direction of rotation of the shaft.
The selected direction of rotation is visible on the display.
Standard setting:
- right sense of rotation, to tighten .
- left sense of rotation, to loosen .

9.1.1) Checking screws (every 5 hours of operation)
Check and re-tighten all screws where necessary.
9.1.2) General verification (every 60 hours of operation)
Check all functions of the machine
9.2) EXTRAORDINARY MAINTENANCE
9.2.1) Checking the impact unit
The impact striker and anvil are subject to wear. Should a noticable loss of torque be detected over intense
and/or prolonged operation, check these components for wear.
9.2.2) Changing grease in the impact unit (at least once a year)
Under normal operating conditions, replace the grease in the unit at least once a year, to maintain effi-
ciency and performance.
Maintenance operations described in § 9.2.1 and 9.2.2 require qualified personnel, please contact
CEMBRE.

11. OPTIONAL ACCESSORIES AVAILABLE ON REQUEST
When work has been completed, store the impact wrench by proceeding as follows:
Remove batteries from the impact wrench, thoroughly clean them with a dry cloth.
Carefully clean the impact wrench.
Place the impact wrench, batteries, battery charger in a sealed place free from dust, moisture and the
risk of accidental impact.
The optimum storage temperature of the batteries is between 10 °C and 30 °C (50 and 86 °F).
For better protection CEMBRE recommends the use of the VAL-NR-25B steel case to store the impact
wrench, batteries and battery charger.
