3.1) Control grip
Thecontrol griphas been designed to provide easy and comfortable access to theoperating
buttons both in vertical and horizontal positions (Ref. to g. 8, 9).
Refer to Fig. 2 and operate as follows:
Horizontal use - Hold the control grip so as to use SAFETY INTERLOCK (15H) and AC-
CELERATOR BUTTON (02H).
Vertical use - Hold the control grip so as to use SAFETY INTERLOCK (15V) and AC-
CELERATOR BUTTON (02V).
To facilitate starting the wrench, the accelerator must be locked in the semi-acceleration
position.
To do this follow the operations below in the order given:
1. Move the selector (13) to po-
sition 5.
2. Hold the control grip (01) so
the safety interlock (15) is
pressed.
3. Press fully and hold the acce-
lerator button (02).
4. Press the accelerator lock but
ton (11) and release the ac-
celerator, which will remain
lockedinthesemi-acceleration
position.
After starting engine (see § 5),
operate the accelerator (02)
which, on release, will bring the
the engine to the minimum revs.
To avoid accidental acceleration, the safety interlock must always be pressed
before the accelerator button is operated.
3.2) Assembly / disassembly of sockets (available separately)
The wrench is preset to receive sockets available on the market having the following
features:
– Specied for impact tooling.
– Assemble on to 25.4 mm (1”) square shaft with through bore.
Before use, always check to make sure the socket shows no signs of breakage or
particular wear. If the socket does not t tightly on the square shaft this could result
in a loss of power and excessive wear of components.

To assemble the socket (Ref. to Fig. 7 page 67):
1Slide the socket onto the square shaft (08) lining up the bores of the socket and the
shaft (Ref. to Fig. 7a).
2Fully insert the central split pin of “CLIP-NR” into the through bore, ensuring the sprung
arms are correctly located in the slot around the socket (Ref. to Fig. 7b).
To disassemble the socket, extract “CLIP-NR” by simultaneous lateral pushing on both
ends of the sprung arms (Ref. to Fig. 7c).
Keep the “CLIP-NR” in a safe place to avoid loss or damage.
Any accessory (extension, adapter, joint, socket) must be specied for use
with impact tools.
The use of unsuitable accessories could lead to breakage.
3.3) Torque adjustment (Ref. to Fig. 3)
Thewrenchisequippedwithasystemwhichallowstorque
limitation on tightening and loosening.
Forparticular requirementsit ispossible tovary thetorque
by means of a 5 position selector (13).
To select torque values, simply turn the selector in one
direction or the other.
Usually selector (13) is set:
–in the tightening phase on low torque settings,
pos. 1 - 2 - 3.
–in the loosening phase on high torque settings,
pos. 3 - 4 - 5.
3.4) Setting the rotation direction (Ref. to Fig. 4)
The rotation direction of the shaft is set using the 3 position
selector (12):
: right sense of rotation, to tighten.
: idle position (main shaft gears disengaged).
: left sense of rotation, to loosen.
WARNING: adjustment of selector (12) must always be carried out with the engine
switched off or idling to ensure correct engagement of gears.
Once a rotation direction has been set, the rotation of the square shaft will be achieved
only by increasing the revs of the engine consequent to automatic intervention of the
centrifugal clutch.
3.5) Operation
With the impact wrench placed on the ground on a at surface, carry out the following in
the order shown:
– Add fuel mixture to the tank (see § 4).
– Choose the socket appropriate to the work to be carried out and assemble it on the
square shaft (see § 3.2).

– Make sure the rotation direction selector (12) is in position “N” (idle position).
– Start the engine by following the procedure in § 5.
– Make sure the torque selector (13) is adjusted to the torque setting required (see § 3.3).
– Lift the wrench and move it to the work location.
– Position the socket over the head of the screw, bolt or nut, so it is completely inserted
into the socket (Ref. to Figs. 8 and 9).
– With the engine at minimum revs, set the rotation direction of the wrench (see § 3.4).
– Keeping a tight grip the wrench increase the speed of the motor to the number of revs
required by using the accelerator (02): in this way the impact striker will come into action
with consequent tightening/loosening of the fastening device.
– On nishing the operation, release the accelerator.
The impact wrench can be used independently or in conjuntion with the
Cembre sup-
port trolley (Ref. to Figs. 10, 11) and appropriate interface device (see § 8) .
– The impact wrench can be used in vertical position with support trolley by tting inter-
face device type KCS-NR .
– The impact wrench can be used in horizontal position with support trolley by tting inter-
face device type KHOR-NR.
4. FUEL MIXTURE PREPARATION
The impact wrench motor is two stroke and functions on an oil-petrol mixture.
To ensure the correct amount of oil is used in the mixture, use the calibrated measure
provided (see gure).
To get the best performance from the motor we suggest using synthetic oil for 2
stroke motors in the ratio of 1:50 (2 %).
As an alternative use mineral oil for 2 stroke motors in the ratio of 1:25 (4 %).
Always use good quality oil.
We recommend a minimum 90 octane
petrol.
Mix petrol and oil together well and prepare only enough
for immediate use as the mixture will age and if several
weeks old may cause engine damage.
Always use the correct fuel mixture to avoid:
1 - Motor smoking and dirtying of the spark plug should
the mixture be too rich with oil.
2 - Excessive overheating with consequent seizing of
the motor should the mixture be lacking in oil.

– Move rotation selector (12) to position “N” (see § 3.4).
PRELIMINARY PHASE:
– Press the easy start button (D) (Fig. a).
– Draw mixture into the carburettor by pressing primer (P) 5- 6
times (Fig. b).
With motor cold:
– Move switch (14) to position “ - START “ (Fig. c)
With engine hot or in hot environment:
– Move switch (14) to position “ “ .
– Lock accelerator (02) in the start position (see § 3.1).
– Give one or two rapid and energetic tugs on the starter cord
(Fig. d).
– Move switch (14) to position “ “ .
STARTING:
– Pull the starter cord until the engine starts.
Note: in order to make it easier to pull the starter cord, always press
easy start button before each pull.
To avoid damage, always follow through with the cord as it rewinds and
do not pull it beyond its stroke.
– Allow the wrench to “warm up” for 2 minutes prior to com-
mencement of work.
NOTE: the effective power of the engine will be reached
after settling in over the use of 2 tanks of fuel during which
time the wrench must not be used at top speed and/or for
intense or prolonged periods.
– To switch off the motor, release the accelerator (02), then
move the switch (14) to the “O - STOP” position (Fig. e-f).

5.1) Carburettor
The carburettor is factory set for optimum performance and adjustment should be
avoided.
5.2) Adjust idling
In case of unstable running at idle speed, allow a short warm-up period then (Ref. to Fig. 6):
Remove the lter cover and adjust the screw (M) so the engine runs in a stable condition
at minimum revs. (2600 - 2800 rpm).
In idling position the transmission shaft must not turn.

OPERATING IN WINTER (Ref. to Fig. 5)
To optimise carburettor function when operating in temperatures below 10°C we advise
mixing cold air with the hot air coming from the cylinder area so as to pre-heat the intake
air. To do this all that is required is to:
– Remove the cover and air lter (see § 6.1.1) placing the cover (C) in view.
– Loosen screw (X) and turn the position the inlet cap (C), tighten screw (X).
– On completion, replace the air lter and cover.
