 Remove the wires from defective inverter
switch.
 Connect the wires to the new switch following
the proper electric diagram.
 Mount the switch on the electric box.
 Mount the speed label with its plastic
protection.
 Mount the white spacer.
 Mount the handle.
 Turn the machine on and check the chuck
rotation way in both speed.
 If the chuck rotation way is not the same in
both speeds verify which is the speed at which
the chuck motor is turning wrongly.
 Dismount again the inverter pole switch.
 Take the electric diagram and reverse two
wires of the wrong speed cable.
 Mount the switch again and check the rotation
way again.
 Mount the chuck motor terminals cover.
 IMPORTANT: WHEN REMOUNTING THE
MOTOR TERMINALS COVER BE CAREFUL
NOT TO CRUSH WIRES.
5.8 CHUCK MOTOR CABLES: CHECK
AND REPLACEMENT
 : 1h
 : Big and medium cross screwdrivers, 7mm
tube type wrench, pliers, multimeter
L : Defective chuck motor cable may cause the
following malfunction:
1. Low chuck power.
2. Noisy motor.
3. Fuses F1,F2,F3 blow up.
4. Motor damaging (burning).
5. Chuck motor does turn in one or both speeds.
TO CHECK THE CABLES:
 Disconnect power supply.
 Open the electric box (5.0).
 Remove the motor terminals cover and all
wires from terminals.
 Remove the inverter pole switch from the
electric box (5.7).
 Select the multimeter in Ohm and check if
there is continuity between the ends of each
wire of the same cable.
TO REPLACE THE CABLE:
 Release cable strain relief on the electric box
and on the motor.
 Take the wrong cable away.
 Insert the new cable through the strain relief.
IMPORTANT!
USE ONLY APPROVED CABLE AND GROUND
WIRE MUST BE LITTLE LONGER THAN THE
OTHER ONES.
NOTE: Before connecting the wires ends, tighten
all terminals nuts on the motor.
 Fit new fastons on wires ends and connect
them to the motor and to the inverter pole
switch Q3 terminals.
 Check if the chuck motor rotation way is
correct and if it is the same in both speeds: if
the motor change direction changing the
speed, take the electric diagram and reverse
two wires of the wrong speed cable on the
motor only. If the chuck motor turns in wrong
direction in both speed, reverse the wires 8
and 9 of the remote control cable on the wire
terminal into the electric box (5.0).
 Mount the motor terminals cover.
 IMPORTANT: WHEN REMOUNTING THE
MOTOR TERMINALS COVER BE CAREFUL
NOT TO CRUSH WIRES.
