1. APPLICATIONS
Kolver electric screwdrivers are designed to tighten to preset torque values any fasteners up to M5.
Tabel 1 will help you to identify the capacity and the torque range of each model. Precision assembly
industries in the field of electronics, electric appliances, toys, glasses frame and so on, are the natural
users of electric screwdrivers .

USE
The screwing system is composed by a screwdriver and a cable with schuko plug.
To install it please follow the instructions.
a.
Pull the collect ring of the quick change chuck, insert the desired bit into the
¼
” seat and release the
ring. The bit is automatically locked into position .
b.
Connect the screwdriver plug to a mains supply socket 230v- 50Hz .
c.
Put the bit head firmly into the fastener head, position the forward / reverse selector upside .
PUSH AND LEVER COMBINATION FUNCTION
(switch on the PL position).
Apply axial pressure through the tool onto the fastener. Then, press the trigger to start tightening the
fastener. When the preset torque is reached , the tool stops automatically.
PUSH START FUNCTION
(switch on the P position) .
Make sure to keep the tool bit straight onto the fastener. Then, push to start tightening (same as PL
function but no need to press the trigger).
IMPORTANT:
For each second of operation the motor needs 3 seconds of rest, as indicated on
the tool label (1s/3s). Failure to do so may result in motor overheating and eventually damage and
will be considered as a misuse. Our warranty will not apply.

ACCESSORIES
Use only
¼
” ISO 1173 bits and power bits.
4.
ADJUSTING THE CLUTCH
The torque values is adjusted by changing the tension of the clutch spring. The torque can be increased
by turning nut #811 clockwise and decreased by turning it anticlockwise.
To check the torque value we suggest the use of KOLVER K1 or K5 torque tester.
4. MAINTENANCE
The D.C. motor is equipped with two carbon brushes 8mm long. When their lenght is about 5mm it is
time to replace them with new ones as per the following instructions.
a.
Unscrew cover # M-308 and let the carbon brush come out of its seat.
b.
Insert a new carbon brush and screw back cover # M – 308.
The average life of carbon brushes is approx 1 milion cycles.
Note
The sound level generated by Kolver electric screwdrivers is always lower than 70dB(A).
The vibrations transmitted to operator’s hand are lower than 2,5m/s
²
. In particular the exposition to
vibrations is lower than 1m/s
²
for operators who make up to 4200 screwing cycles per day.
