INSTRUCTIONS
DISASSEMBLING THE TURBINE
● Position the power tool in a vice fitted with
soft jaws.
● Unscrew the adapter (1).
● Extract the cylindrical spring (4), the disc
spring (7), the conical spring (8) and the ball
(9).
● Remove the lever complete (12, 18, 19).
● Unscrew the bushing complete (13).
● Remove the valve (5) and the inlet (6).
● Extract the turbine from the housing (32).
● Unscrew the speed governor (20)
Left thread (see figure 2).
● Remove the turbine (see figure 3).
● Slightly clamp the rotor in a vice fitted with
soft jaws in order to unscrew the pinion.
DISASSEMBLING THE ANGLE HEAD
● Unscrew the plug (50).
● Remove the washer (49).
● Extract the shaft sub-set (41, 42, 43, 44), the

and the nut (46).
● Unscrew the nut (46) in order to detach the
pinion from the shaft (41, 42, 43, 44).
REASSEMBLING THE ANGLE HEAD
● Lubricate the shaft pinion with grease and
proceed with reassembling.
● Tighten the plug (50) to a 60Nm torque.
REASSEMBLING THE TURBINE
● Proceed in reverse order with respect to
disassembly.
Be careful with the direction for
assembling the blades (24)
(see figure 4).
● Apply a small quantity of "Loctite 641" on the
thread of the governor (20) before tightening

REAR CAP
● The lever complete has two 180° adjustable
positions (see figure 5).
● When reassembling, centre the disc springs
(7) on the conical spring (8).
● Tighten the adapter (1) to a 30Nm torque.
LUBRICATING THE BEVEL GEAR
● Amount of grease:
- 3.5g : 12000 / 13500 rpm
- 5g : 6000 / 7500 rpm
● Recommended grease: 6159901490 (24 g)
or 6159901480 (1 kg).
● The use of any other lubricant, in higher or
lower amount, will shorten the life and impair
the operation of angle pinions.
Be careful when clamping the tool in the
vice (see drawing below).
