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.

PUMP CRANKCASE LUBRICATION
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.
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.
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.
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.
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.
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.
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
Incoming water supply must not exceed 60°C, otherwise pumps seal damage could result
Follow engine manufactures guidelines for engine maintenance, (see engine manual)
DO NOT RUN EXCESSIVE BY-PASS SWITCH MACHINE OFF WITHIN TWO MINUTES OF CEASING OPERATION AS EXCESSIVE BY-PASS CAN CAUSE HEAT BUILD UP IN PUMP AND SUBSEQUENT DAMAGE.
EXCESSIVE BY PASS RUNNING VOIDS WARRANTY!!

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.
GRIT BLAST HEAD SET UP INSTRUCTIONS
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.
1.
4. Squeeze the gun trigger to bleed air as normal keeping the tip
of the gun pointing down. 2.
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.
Unwind the tail coupling and remove top of the blast head. Screw in the nozzle to the tail.
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.
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. 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.

Resetting the Safety Valve …ONLY TO BE CARRIED OUT BY QUALIFIED SERVICE TECHNICIAN
The safety valve prevents damage to the pump seals and valves 5. 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 6. 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
7.
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.
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.
Repeat running with the trigger open and then closed two or three times to ensure safety valve doesn’t blow off pressure.
If safety valve continues to trip contact your nearest wx-jet service centre.
