WorkPro RP17407 Instructions D'origine page 8

Insert 3-5 drops of special compressed air oil into

the compressed air connection (see figure 2)
Let the equipment run briefly so that any surplus oil

is blown out.
NOTE : This tool also features a grease cap (C) on the
protector cover. Use a grease gun (not provided) and
insert the gun nozzle into the grease cap (C). Several
drops of grease are recommended for lubricating the
internal hammer assembly. This will help the hammer
assembly to work in good condition and extend tool
life. Lubricate the hammer assembly once every
working day. (See Figure 3)
5.3 Inserting/removing a tool (Fig. 4)
Fit the required drive socket insert by pushing onto the
anvil (B).
Remove the drive socket by pulling it off the anvil (B).
6. Operation
6.1 Connecting to a compressed air supply
Remove the air inlet protective cap from the air inlet
(E). Mount a air connection by hand into the air inlet (E).
(See Figure 4) , Connect air supply hose (not supplied)
to the air connection. Set the working pressure at 90
PSI for best tool performance.
6.2 Rotational direction / torque switch
You can select counter-clockwise or clockwise rotation
and the torque using the reverse or forward exchange
knob(F). (See Fig.5)
Torque selector
Important!
To avoid gear damage, make sure that the tool has come
to a complete stop before you change the direction of
rotation (See Fig. 6).
6.3 Choose the correct impact socket (not provid-
ed) as needed and mount it onto the anvil (B). (See
Fig. 7)
Warning!
Only use impact sockets that have an RPM rating
equal to or greater than the tool itself.

6.4 If longer reach is necessary, use an extension
bar (not provided) and then mount impact socket
(not provided) onto the bar. (See Fig. 8)
Loosening:
Set the direction of forward and reverse exchange

knob (F) to counter-clockwise, press the trigger (D),
the tool anvil (B) runs counter-clockwise to remove/-
loosen threaded fasteners.
Mount a drive socket insert on the impact driver (see

point 6.2).
Place the impact driver on the screw/nut and press

the trigger (D).
Tightening:
Warning! Use the impact driver only for loosening

screws/nuts. If you want to use the impact driver to
tighten screws and nuts, you must also use a torque
limiter (not included) which is designed for this
purpose. If not, the screw connection may be
damaged.
Prior to tightening, carefully insert the screw/ nut

into the threads.
Set the direction of forward and reverse exchange knob

(F) to clockwise, press the trigger (D),The tool anvil (B)
runs clockwise to install/tighten threaded fasteners.
It is important that screws/nuts with special torque

specifications (for example provided by the vehicle
manufacturer in the automotive sector) are tightened
only with a suitable torque limiter.
Danger!
Screws/nuts must be finish-tightened with a torque
wrench which is set to the torque specified by the
manufacturer and then they must be checked!
7. Cleaning and maintenance
Disconnect the compressed air supply from the
equipment before performing any cleaning work.
7.1 Cleaning
Keep all safety devices, air vents and the motor

housing free of dirt and dust as far as possible. Wipe
the equipment with a clean cloth or blow it with
compressed air at low pressure.
We recommend that you clean the device immedi-

ately each time you have finished using it.
Clean the equipment regularly with a moist cloth

and some soft soap. Do not use cleaning agents or
solvents; these could attack the plastic parts of the
equipment. Ensure that no water can seep into the
device.
