- Do not point gun at anyone or at any part of the body.
- Never spray without tip guard.
- Do pressure relief if you stop spraying or being servicing sprayer and before any maintenance operations.
- Do not use components rated less than sprayer Maximum Working Pressure.
- Never allow children to use this unit
- Brace yourself; gun may recoil when triggered.
If high pressure fluid pierces your skin, the injury might look like “just a cut”, but it is a serious wound! Get
immediate medical attention.
It is obligatory to wear suitable clothing as gloves, goggles and face shield.
Wear clothing that complies with the safety standards in force in the country in which the equipment is used.
Do not wear bracelets, earrings, rings, chains, or anything else that may hinder the operator’s work.

INSTRUCTIONS OF USE
C
Before connecting the spray gun to the pump,
select the nozzle type, which fits to the kind of
work you’re beginning (see table).
SAFETY LOCK
Be sure that the trigger is locked, by rotating the
safety lock (all spray guns get out from Larius
safety locked).
Make sure that the spray fan of the nozzle is in
the correct position (horizontal or vertical), apt for
the kind of work you’re beginning.
Connect the high pressure hose to the spray gun.
The correct installation should be done by using
a hose hawing a grounding connection, otherwise
it is possible to connect a grounding wire to the
screw 31 and fix it all along the hose itself, by
means of a tape or clamps.
Control that all the threaded fittings both of spray
gun and of pump are perfecity tightened.
Keeping the safety lock inserted, set the spray gun
under pressure and, keeping the nozzle far away
from you or any other person, unlock the safety
lock, press on the trigger and begin lo spray.
In order to avoid accidents, whenever you must le-
ave the spray gun unattended, lock the safety lock.
At the end of the work clean spray gun and pump
with the solvent apt for the product, which is being
used.
SERVICING
D
Before proceeding with any servicing, be sure that
the spray gun has no pressure inside and that the
product is finished.
PUNCH SETTING
For getting a correct working the punch (D2) mo-
ved by the trigger (D7) should open of roughly 3
mm. This setting must be done by acting on the
nut (D3) screwing or unscrewing the punch (D2)
in the sleeve (D4) and locking then the nuts (D3).
After having reassambied the pipe (D1) on the
spray gun, control that the distance between the
nut (D6) and the screw (D5) is about one millimeter.
This guarantees that the setting has been correcty
done. During the setting, release the safety lock,
in order to allow the movement of the rod.
LEAKS
It any leak of product should occur, it is sufficient to lock
the screw (D5) which has the function of a stuffing box.
REPLACEMENT OF THE PUNCH
Unscrew the pipe (D1) of the spray gun. Take out
the rod from the pipe anda control the punch (D2).
In order to replace it, you need to unscrew it, after
having loosened the nut (D3). Proceed then to the
setting, as described before. During the operations
of disassembly and reassembly of the rod in the
pipe, keep the trigger open (safety locked), in order
to avoid damages to the rod, in the case that this
latter forces on the ball seat in the sleeve.

REPLACEMENT OF THE SEALS OF THE SPRAY GUN BODY
E
A) Take out the pipe (E1)
B) Remove the rod with the punch.
C) Remove all the control part of the rod (trigger,
guard, safety, etc.)
D) A light pressure on the rod will allow the ex-
traction of the seals (E2)
E) During the disassembly of the safety lock (E5)
it is necessary to unlock it completely (clockwise)
and unscrew the complete part from the gun body.
Pay attention to the light residual pressure on the
main spring (E4), it is therefore advisable not to
expose any part of your body near to it.
During the reassembly, make sure that the safety
nut (E5) is locked, in order to make the insertion
and the assembly in the gun body easier.
A light pressure will be necessary to make this
possible.
