WXSEMT SAFE BLASTING

MODELS:
Products in accordance with the Chinese Machinery Industry Standard Production JB/T 6909-2014 below applies to the following WXSEMT high presure water blaster models: JB/T 6909-2014 SMP500-15G

DESCRIPTION:
Engine drive hydro-blasters designed for professional cleaning applications.

MATERIAL CONSTRUCTION:
wxsemt pressure washers are mounted on heavy duty trolley mounted frames. They consist of a quality internal combustion petrol engine driving a triplex style three piston high pressure pump. The machines are supplied with wheels for ease of portability and manoeuvrability.

RISK RANKING METHOD:
Risk is the combination of the likelihood of a specific unwanted event and the potential consequences if it should occur.

RISK RANKING TABLE:

The consequences (loss outcomes) are combined with the likelihood (of those outcomes) in the risk ranking table to identify the risk rank of each loss event (e.g. a consequence of “Moderate7 with a likelihood of ‘Likely’ yields a risk rank of 17).

The table yields a risk rank from 1 to 25 for each set of probabilities and consequences. A rank of 25 is the highest magnitude of risk that is a highly likely, very serious event.
A rank of 1 represents the lowest magnitude of risk, an almost impossible very low consequence event.
Controls must be taken to either eliminate or minimise the risk.

ASSEMBLY AND PREPARATION FOR USE

Before proceeding with assembly of your new wxsemt high pressure blaster, check that all parts listed below are included.

• 1 x 700bar gun lance assembly
• 1 x 800 bar high pressure hose
• 1 x Inlet filter
• 1 x Inlet pipe
• 1 x Return pipe
• 4 x nozzle

Connect the high-pressure hose

Connect the gun. The gun has been equipped with a lance. Mount the trigger gun with the lance to the
high-pressure hose. Use wrenches to tighten their connection

A, Machine Preparation (initial start・up)
Check the oil in the pump and gearbox. Note separate reservoirs. With the machine on a level surface the oil level should cover the red spot in the oil level sight glass on the side of the machine. If necessary, top up pump with SAE 75W-90. Do not mix different grades of oil as this may affect the machines performance. If alternative oil is used, first empty out oil by unscrewing drain plug in bottom of machine.

Ensure breather plug is fitted to pump. WARNING: Before operation ensure top mounted travel plug is replaced by breather plug. Failure to fit breather and keep clean can result in over pressuring of oil chamber (crank case) and can blow oil seals.

This will void warranty.

1. Note that the gearbox has a separate oil reservoir. Gearbox oil is SAE 90 gear oil.
2. Connect battery lead switch
3. Check oil level in engine, check engine manual for details of oil to use.
4. Check fuel level and fill if necessary.

UNLOADER SETTING
The high pressure unloader on the machine is factory set to operate the pump at it’s rated pressure.
DO NOT ADJUST. Tampering with the unloader will void warranty and can be dangerous.

B, Hose Connections

1. Connect high pressure hose to machine outlet.

2. Connect gun/lance assembly to high pressure hose.
   Use hose shroud to cover the coupling.

3. Check inlet water filter is clean then connect water supply hose to machine. Use a 25mm (minimum) hose . Flush out hose before connecting to remove any obstructions.

Incoming water supply must deliver double the flow of the machine. If questionable, check supply at machine. If supply is insufficient, do not operate from this outlet. For residential use, the outlet closest to the meter will usually deliver the highest flow rate. Connect only to clean town water supply.

Warning : Do not operate from tank or pond. Doing so will cavitate the pump causing damage danage. Cavitation or pump starvation is not covered by warranty. Cavitation is a phenomenon causing vacuum pockets to form within the pump that eventually implode under pressure pitting the internal pump surfaces.

Before starting the machine
OPERATE IN WELL VENTILATED AREAS ONLY.

1. Ensure machine is level
2. Turn on water supply.

Starting the engine

1. Connect the water inlet hose to the inlet connection of the filter, connect the hose to the water inlet pagoda joint, and tighten the hose clamp with a screwdriver
2. Connect battery at battery isolator.
3. The throttle of this machine has been set, no need to adjust
4. After opening the damper switch, start the engine, with the engine warmed up for 10 seconds, close the damper and use it normally
   The machine pulls the trigger, automatically refuels, releases the trigger, and automatically idles.

KEEP THE MACHINE OUT OF MOISTURE LADEN ATMOSPHERES
NOTE: Check the system for water leaks, fuel leaks, oil leaks, hose kinks, etc. Correct any problems before proceeding.

HIGH PRESSURE SPRAY CAN PENETRATE THE SKIN & CAUSE SERIOUS INJURY!
Never point the spray gun at yourself, other people or animals.
Should the spray penetrate the skin SEEK MEDICAL ATTENTION IMMEDIATELY!

Stopping the machine

1. Allow machine to run for 1 minute without load to cool before stopping.
2. Turn the Black Knob to start the engine
3. Turn the engine key to OFF
4. Battery isolator can be locked off to prevent blaster from operating.
5. Turn off water supply.
6. Pull gun trigger to release all pressure in the system, then LOCK THE TRIGGER.
7. Hoses may now be disconnected from the machine.

Failure to release pressure before /disconnecting the hose quick coupler will result in the quick coupler o-ring seal blowing out. This o-ring must be replaced before operating machine.

CARE AND MAINTENANCE:

AFTER EACH USE
If cleaning agents have been mixed with the incoming water, it is essential to flush the machine with clean water after use.
If there is a danger of freezing anti-freeze should be mixed with the flush water or the machine must be completely drained.
After the final flush stop the machine. DO NOT allow the machine to idle for more than 15 seconds. This is particularly important when there is a danger of freezing. Do not run for longer without water supply.

STORAGE
Store the washer in an upright position, preferably drained of water if there is a danger of freezing (or fill with antifreeze).

PUMP CRANKCASE LUBRICATION
Proper pressure washer pump crankcase lubrication will help extend the working life of the machine. Follow these important guidelines. We recommend keeping a simple service log book.

• Change pump oil every 40 hours of use high quality oil.(SAE 75W-90)
• Pump oil level can be checked with the dip stick under the breather cap or by viewing the oil sight gauge where fitted. The oil level is correct if level is in the centre of the gauge. If oil level is low, fill to correct level with recommended oil (SAE 75W-90). DO NOT OVERFILL CRANKCASE!
• Replace oil in gearbox (separate chamber) with SAE 90 gear oil every three months.

PREVENTATIVE MAINTENANCE

• Rinse filter in supply hose connection regularly.
• Use correct size nozzles for machine and replace when worn, check serial tag for correct size.
• Drain water from pressure hoses, gun/lance assembly and accessories after use.
• Protect pump from freezing. Failure to remove water from the pump in freezing temperatures will result in damaged pump manifold.
• Use ONLY injector of the size and type designed for this model.
• DO NOT tamper with unloader valve adjustment or alter engine speed.
• DO NOT siphon chemicals through the pump, it is designed for water only.
• Incoming water supply must not exceed 60°C, otherwise pumps seal damage could result
• Follow engine manufactures guidelines for engine maintenance, (see engine manual)

WARNING: CHECK NOZZLES AND REPLACE IF WORN
If pressure drops off, check nozzle for wear.
Nozzles should be replaced every 40 hours. Using the machine with the incorrect nozzle size or worn nozzle will void warranty and can be dangerous to the operator.

WXSEMT GRIT BLAST INSTRUCTIONS (optional accessory)

WARNING: To reduce the risk of injury, always protect eyes and face with safety glasses and mask, and hands and arms with heavy work gloves when spraying abrasive materials.

1. Fit grit blast gun/lance kit at end of high pressure hose, in place of normal gun/lance assembly.
2. Lodge sand probe into sand bag. Note the sand must be dry.
3. Connect and open the water supply line to the blaster before starting the pressure washer.
4. Squeeze the gun trigger to bleed air as normal keeping the tip of the gun pointing down.
5. Turn on the pressure washer and squeeze the gun trigger to activate the spray. CAUTION: Always test spray on a scrap of similar material first! The high pressure spray could damage the surface if the grit blaster is held too close.
6. To determine best distance for grit blasting, start with the spray nozzle a metre away from the surface and gradually move closer, frequently checking the surface for damage.
7. Always point the nozzle downward when not spraying. This prevents water from entering the sand supply. If water does get into the sand supply hose, remove the probe from the sand, hold the gun trigger open, and let the hose air dry. Always be sure the sand hose is dry before using.
8. Keep the sand covered to prevent the overspray from wetting the sand. Do not allow small pieces of the sand bag to fall into the sand supply as they could prevent the flow of sand.

GRIT BLAST HEAD SET UP INSTRUCTIONS

1. Unwind the tail coupling and remove top of the blast head. Screw in the nozzle to the tail.

2. Replace the tail and ensure that the tip of the nozzle is a minimum of 28mm from leading edge of body and a maximum of 36mm.
   The fan spray from the nozzle should be perpendicular to the sand intake tail. Mark the top side of the hexagonal coupling for reference.

3. Line up the dimple in the ceramic nozzle perfectly with the sand intake tail and hold in place with the holder. Screw down the head locking nut.

4. The fan produced by the two nozzles must be aligned.

5. Connect grit blast head to hp gun/lance and activate the gun with the high pressure blaster running. Check the fan jet leaving the nozzle is the full width of the slot. Adjust by rotating hexagonal tail coupling, ensuring that the marked side of the tail always finishes on top.

6. With the high pressure washer turned off, connect the sand hose to the sand intake tail and secure with hose clips.

ACCIDENT REPORTING

Reporting.
All accidents or injuries, whether resulting in “lost time” or “no lost time” injuries, should be recorded in accordance with the recommendations of Incidents that result in “near misses” should also be recorded as a means of providing a record of significant incidents that have the potential to result in serious injury at the workplace, so appropriate measures can be implemented to minimise or eliminate these potential hazards.

Personal Injuries.
In the event that a person is injured by the impact of a water jet, the injury caused may appear insignificant and give little indication of the extent of the injury beneath the skin and the damage to deeper tissues. Although only a small hole may be present, quantities of water may have penetrated the skin and entered the flesh and organs causing serious injury.

Medical Recommendation.
If an accident occurs where pressurised water penetrates or appears to have penetrated the skin, medical assistance should be sought immediately.

Immediate First Aid.
Where medical examination is not immediately possible (e.g. in remote situations), appropriate basic first aid measures should be applied and the patient observed closely until medical treatment is available.

Medical Alert Card.
All operators engaged in commercial and industrial water blasting operations should carry out an immediately accessible, waterproof medical alert card. This card should:

• outline the possible nature of injuries and postaccident infections that can be caused by high pressure water blasting;

• provide details of immediate first-aid treatment until medical treatment can be arranged; and

• provide the name or names of medicos (and contact phone numbers) who should be contacted for expert medical advice for the treatment of high pressure water blasting injuries.
  In addition, the card may also:

• identify the worker; and

• outline medical information about the worker; e.g. blood type, allergies and conditions, such as asthma.

EMERGENCY MEDICAL INFORMATION

Immediate hospital attention should be given to personnel who sustain equipment related injuries while operating the system. In such cases, it is vital that medical personnel be apprised of all facts relevant to such injuries.
Therefore, all operating personnel should be provided with waterproof emergency medical tags or cards describing the nature of their work and the possibility of injury inherent in the use of a water blasting device. The tag or card should also bear the following standard notice:

Resetting the Safety Valve …ONLY TO BE CARRIED OUT BY QUALIFIED SERVICE TECHNICIAN

The safety valve prevents damage to the pump seals and valves caused by a pressure spike.
The safety valve should only be reset after checks to ensure the unloader valve is working correctly. If in doubt contact, your nearest wxsemt-jet service centre.
The following steps should be taken to reset the safety valve, with the unit running.

1. Unscrew the lock nut (C) on the safety valve and the adjusting the hex knob (D), it should be screwed in all the way.
2. Loosen the lock nut (B) on the unloader and wind the unloader knob (A) in gradually until the required pressure is obtained whilst the trigger is pulled and water is running through the pump. Do not exceed the maximum rated pressure of the pump.
3. The lock nut (B) should then be wound up to meet the adjusting nut. The small grub screw in the locking ring should be screwed in to secure.
4. Paint mark across the nut and knob to identify any tampering with the setting.
5. With the pump running at the required pressure, the adjusting screw (D) on the safety valve should be wound out until there is a slight drip. Screw it in one quarter of a turn, or until the drip stops, this will set the safety valve 10% over the required pressure. The lock nut (C) should then be locked off. Paint mark to identify any tampering.
6. Repeat running with the trigger open and then closed two or three times to ensure safety valve doesn’t blow off pressure.
7. If safety valve continues to trip contact your nearest wx-jet service centre.
