Safety

Power washers should only be used by fully trained, competent persons. They should not be used by untrained or inexperienced users.
Care should be taken when handling the pressure washers as they have uneven centres of gravity and may topple over when lifted.
3.1 Suitable Persons
Operators should be physically fit and free from the influences of drugs or alcohol.
Prolonged periods of operation are strenuous and operators should be encouraged to take regular breaks. If you have any doubts about your fitness to operate this equipment, seek professional advice before proceeding.
3.2 Protective Clothing
Operators and assistants should wear the following Personal Protective
clothing and equipment: –
Waterproof boots with good non-slip soles
Waterproof overalls
Waterproof gloves
*Goggles or full-face protection to at least BS EN166
Ear Muffs or Ear Plugs to give protection to at least EN352-1. EN352-2
3.3 Use in confined spaces
Diesel and Petrol engines produce fumes and toxic gases, use only in wellventilated spaces.
To prevent the build up of flammable vapours the charging of petrol and diesel tanks should not be done in confined spaces. Any spillages should be cleaned up and any absorbent material used should be disposed of in a proper manner.
3.4 General Safety
Check all hoses and couplings for tightness and damage, loose connections should be tightened and damaged hoses replaced.
Ensure the workspace is clear and free from obstructions; consideration should be given to the erection of fences or sheeting to prevent injury to others.
High-pressure lances react ‘Kick Back’ when the operating trigger is pulled. Ensure you have a good firm footing and anticipate this reaction.
Extra care should be taken when working at heights, scaffolding should be in good condition, secure and properly fenced, working from ladders is not recommended.
The high-pressure stream can be dangerous, do not point the stream directly at others or submit them to the fine over-spray.
3.5 Control of Vibration at Work Regulations 2005
This machine in its standard form does not exceed the 2.5 m/s² vibration action value and should not require any daily limitations to it use. Periodic equipment checks and servicing will maintain the characteristics and efficiency of this machine.
Warning:**
Any modifications or accessories added or use with this machine may affect the vibration levels. Under the Control of Vibration at Work Regulations it is the employers duty to manage the exposure to vibration and implement training and health surveillance for employees.
Under the Supply of Machinery (Safety) Regulations 1992 (SMSR), you should ensure equipment is in good condition and maintained in accordance with the manufacturers instructions, any modifications or accessories added to this machine should be assessed for safe operation and vibration, then implement appropriate measures.

* Note: Goggles or Full Face Protection.
The wearing of eye and face protection in hazardous areas is a requirement under regulation 4 of the personal protective equipment at work regulations 1992.
Regulation 4 requires employers to provide suitable personal protective equipment to employees who may be exposed to risks affecting their health and safety.
Full Face Protection.
High speed flying partials or chemical splashes are rarely aimed directly at the eyes. A full face visor offers the maximum protection in extreme conditions. Full face shields offer a wide area of protection and because of the all round ventilation, remain mist free even in wide temperatures swings.
Chemical Splash.
Chemical splashes and vapours can hit you from all sides. It’s important that full eye enclosure is selected, e.g. Unvented goggles. Full face shields will also protect the whole face from liquid splashes. Those with chin guards should be selected where there is a danger of splash deflecting up from work surfaces.
Impact.
Impact hazards are caused by fast moving particles from the cleaning operation. The potential impact speed must be assessed before selecting the most appropriate protection. Safety glasses could be dislodged by high velocity impacts, in which case goggles or face shield should be selected.
** Note: Ear Muffs or Ear Plugs.
The noise at work regulations require that from February 2006 persons working in noise levels between 80dBA and 85 dBA must be provided with suitable hearing protection on request. If noise levels are above 85dBA then hearing protection must be supplied and worn.

Installation

5.1 From the pump and gearbox (if fitted) remove the ‘Red’ travel plugs, replacing them with the yellow-topped dipsticks. Check all oil levels, top up if necessary.
5.2 Fill engine with oil and fuel, see engine manufacturers handbook for details of oil and fuel types.
5.3 Connect the battery leads. (Electric start models only).
5.4 Connect the suction hose to the Power Washer (fig 3). Ensure the connection has no air leaks. Air leaks on the suction hose connection will impair the performance of the machine.
5.5 Connect the water return line to its connector and place the other end in the water supply container. (Bypass to tank models only) (Fig 2 item 16 & Fig 4).
5.6 Submerge the opposite end of the suction hose and its suction filter in a suitable container containing the water supply (fig 4). Ensure the filter is always kept below the water level.
5.7 Connect the high-pressure hose to the power washer (fig 5) and to the lance (fig 6). Tighten as appropriate, do not over tighten.
Ensure that the trigger safety catch is in the ON position whilst making these connections.

Operation

6.1 Start engine (Note: Depress the lance trigger to release water pressure before starting the engine).
Refer to accompanying booklet relating to the type of engine fitted.
6.2 Using High Pressure Lance ( Note: See Appendix 1 for lance type and operation)
Release the lance safety catch, which is located behind the trigger.
6.2.2 Point the lance downwards and towards the object being cleaned.
6.2.3 Squeeze, the trigger to start the high-pressure jet, proceed to wash the object. Adjust the working pressure by turning the pressure regulator knob + or – to suit the application (fig 2, item 13).
Never direct the high-pressure stream at the engine or pump as this could cause irreparable damage.
WARNING: – High-pressure lances react ‘Kick Back’ when the operating trigger is pulled. Ensure you have a good firm footing and anticipate this reaction.
6.2.4 Release the trigger to stop the high-pressure jet.
6.3 Washing using detergent
Attach the detergent induction pipe to the power washer, (fig 2, item 1) placing the opposite filter end into the detergent container. Select the low pressure setting on the lance, (see appendix 1 for details of your lance) and spray the water/detergent mixture onto the object being cleaned. Leave the detergent for the period recommended by the chemical manufacturer allowing it time to work, washing off with clean water. The volume of detergent used can be controlled by means of the regulator on the suction valve (see fig 2. item 3).
6.4 Switching Off
Release trigger.
Stop drive engine, (refer to additional literature/handbook supplied, relating to the type of engine fitted, remembering to switch off ignition after use to prevent draining the battery, electric start models only).
Depress the high-pressure lance’s trigger to release the pressure in the high- pressure hose.
Disconnect water supply.
WARNING: Do not let the pump idle in By-Pass for lengthy periods, if you intend to break from work for more than 5 minutes, switch the machine off. Should the machine run for longer period, the temperature of the re- circulating water will increase rapidly and could risk damaging the pump seals. (Models with internal by-pass only).
Running power washers should never be left unattended.
