Description and function ofthe safety devices
Unloader valve with switch:
The unloader valve limits the operating presur. The desired operating pressure can be infinitely varied with this. If
the max. permissible operating pressure is exceeded or the spray gun closed the unloader valve channels the
water through its bypass line depressurized back to the high-pressure pump.
While the gun is closed the integrated micro-switch will open. About 20 sec. After the mikro-switch opened, the
motor of devices with time delay stop will be cut of.
If thepressure sinks below 10bar , the motor switches on irnmediately again.
*There will be no time delayed stop after the gun closed at devices without time delay stop. The device runs
without pressure in the bypass. /
Attention:
The unloader valve has to be adjusted that overpressure is not more than 10% over working pressure.
Use and description of the equipment
The Weidner Waschbär SE 112/118 is a fully enclosed mobile hot -water high-pressure cleaning device.
The working pressure is generated by a Triplex pump with 3 ceramic plungers. The pump is flange- mounted
directly on thequill motor. There is apressure regulator with mechanical switch, flow controller and presure relief
valve on the high-pressure side of the pump. When the gun ist closed the pressure regulator receives a switching
surge which causes the water conveyed by the high-pressure pump to be retumed to the high-pressure pump' s
suction side depressurized. The motor and pump run without a load. Heating is by means of aflow heaterwith
heating spiral. The oil feed is controlled by thecontrol chain thermostat, flow controller and microswitch in the
mechanical pressure regulator. Ap-type heating oil switch can be incorporated in this control chain as an
accessory.
If workis interruptedfor longerthan 1 minutes the device should be switched offto saveenergy .The device is
suitable to remove dirt from surfaces by means of a freely-expelled water jet. The cleaning device is particularly
suitable forcleaning machines, building facades, stables and floors as well as vehicles such as cars and trucks.
The choice of working pressure depends on the cleaning task. In the case of hard and stubborn dirt the highest
possible pressure should be used for cleaning. The operating pressure depends on the size of the spray nozzle,
whereby the max. operating pressure is limited by the pressure regulator.
Apart from the working pressure and working distance from the object to be cleaned , thejet shape is also
important for the cleaning effect. A round spray nozzle with an angle of O degrees has the highest mechanical
effect an is, e.g. appropriate for cleaning stables or heavily soiled construction machinery and equipment. Normal
work can be carried out with a 25 degree nozzle. In case oflarge-scale cleaning work, e.g. floors, a 40 degree
nozzle can be used.
Important notices
If you discover transportation damage during unpacking pleas contact your Weidner sales office.
Start-up:
Open the stainless steel cover ( 64), check the oil level in the high-pressure pump and top up as required (see
specifications). /
Electrical connections
The voltage shown on the ratings plate must correspond with the voltage from the source of electric power.
The current lead must be fused with 32A on the SE112 ans with 50A on the SE118. A higher fusing is
not allowed.An FI safety switch is to be provided by the customer. .
The electrical connections and mains fusing should ony be installed by a professional.
The device may only be connected to a socket which has been installed in accordance with local laws. Work on
electrical components in the device may only be carried out by a qualied electrican.

Additional safety measures and precautions when working with el
1. Only connect the equipment to regular sources of electric power.
2. Check the cables for darnage before use -never connect damaged cables.
3. Connections must be dry and should not lie on the tl oor .
4. Do not touch the plug with wethands.
5. If an extension cable is used this should be completelyunwound from its drum and should have an adequate
wire cross section, otherwise the cable can overheat (scorch) andcause ashort-circuit;
(Threephase current equipment up to 10 meters long wire cross section 1.5 mm, up to 30 m long 2.5 mm, single-
phase device type Waschbär SE 112/118. ..generally at least 2.5 mm wire cross section.)
Water supply
Connect water hose with Geka coupling on high-pressure cleaner at .
Connect water connection piece.
Fully open water tap.
Water feed pressure min. 2 bar,.max. 4 bar:A pressure reducing va1ve must be incorporatedin the feed
line with higher water mains pressures.
Connection ofthe high.pressure hose
Screw one end of the high-pressure hose onto the pressure output nipple on the device. The other end
ofthe high-pressure hose is screwed to the spray gun.
Cleansant feed and supply
An injector will meter out the cleansant. Connect the cleansant hose to the injektor and place the suction
filter into the cleansant. The quantity of cleansant can be adjusted by turning the hand nut at the cleansant-injektor.
If all the prenamed points are fullfilled, activate the cleansant feed while opening the pressure adjusting nozzle at
the end of the jet pipe. The more the pressure adjusting nozzle is opened the more cleansant will be feed and the
other way around.
The function of the injector takes place only in case of*low pressure*. Feeding takes place only to a max. hose
length of 15 meters. Before using for other purposes consult with the firm of weidner or one of their agencies first.
Protection against freezing
Freeze can destroy equipment which has not been completely emptied of water .The best protection against freeze
is to place the device in a room protected against frost.
Warnings
Do not point the water jet at persons or animals (risk of injuries through pressure and heat as well as irritation of
mucous membranes and acid burn through chemicals ).
Do not point the water jet at the device itself or other electrical components (risk of short-circuits and other
damage ).
The device may not be used in rooms exposed to the risk of explosions.
When using chemicals suitable safety equipment should be worn ( safety goggles, safety overall, safety gloves,
boots etc.).
PIease pay attention to Section " A " of the appendix to VBG 1 35-47, Protection against dangerous chernicals.

Operation
Cold-water operatibn
Appliance switch to "0".
Thermostat to "0" degrees C (off).
Insert appliance plug into socket.
Turn on water supply .
Pull spray gun trigger and set appliance switch to position 1 "pump on".
The device starts.
The pump at first empties the device of air. After a while water comes out of the spray gun. Hold the spray gun
open unntil a steady jet of water is ejected. Now close the spray gun and switch off device.
Screw the lance with nozzle piece (34) onto the spray gun.
The device is now ready for operation.
Attention:
The water jet emitted causes a repulsion power in he spray gun. In the case of an angular lance with a spray
nozzle size 05 the repulsion power amounts to43 N (Newton).
Keep a tight hold on the lance and spray gun.
Cleansant additive
The dilution of the cleansant and the adjustment of the concentration at the metering valve depends on the
cleansant and the field of application.
Cleansant from integrated cleansant tank -turn the switch into the direction "tank".
Cleangant from seperate drum -turn the gwitch into the direction "2" .
If the cleangant tank/ drum is empty the metering valve should be closed (pos since otherwise air will be sucked in
and the working pressure will drop completely. On completion of work with cleansant the device should be
thoroughly rinsed with clear water .
Stopping
