• Prevent fires by keeping engine clean of accumulation, grease, trash and debris.

IMPORTANT: Do not permit dirt or other foreign matter to enter the fuel system. This will cause hard starting, poor performance and engine damage. Always use clean fuel storage containers and funnels.
Use clean, fresh, lead-free gasoline. Do not use stale gasoline or gasoline that has 1tlf j; 1) ‘Ii been stored for a long time. Stale gasoline does not vaporise properly, causing hard starts. Use of fuel set gasoline stabilizer is highly recommended . Use of leaded gasoline or gasohol is NOT recommended.

Connect Hose & Waler Supply To Pump

IMPORTANT: To avoid pump damage, you must assemble the nozzle extension to the spray gun and attach all hoses before you start the engine.

1. Uncoil high pressure hose and attach the end of the hose to base of spray gun (Fig. 3 ). Thread hose fitting on in clockwise direction and tighten moderately.

2. Similarly, attach other end of high pressure hose to high pressure outlet on pump.

3. Before connecting garden hose to water inlet, inspect inlet screen (Fig.4 ). Clean screen if it contains debris, replace if damaged. DO NOT RUN PRESSURE WASHER IF SCREEN IS DAMAGED.

4. Run water through garden hose for 30 seconds to clean out any debris. Turn off water. IMPORTANT: DO NOT siphon standing water for the water supply. Use ONLY cold water (less than 40°C).

5. Connect garden hose (not to exceed 15.24m in length) to water inlet..
   CAUTION! There MUST be at least 3 metres of unrestricted garden hose between the pressure washer inlet and any flow shut off device, such as a ‘Y’ shut-off connector or other con­venience-type water shut-off valve. Damage to equipment resulting from failure to follow this instruction will void warranty.

6. Turn ON water and squeeze trigger on spray gun to purge pump system of air and impurities.

WARNING! High pressure spray can cause paint chips or other particles to become airborne.

Inlet Water Supply Requirements

1. Inlet water supply must be a minimum of 20 PSI (1.4 bar). Attempting to operate the washer with less than adequate water supply will cause rapid wear of packings, valves and bearings that will dramatically shorten pump life. Symptoms of inadequate water supply are pump shuddering and flattening of the supply hose.

2. Inlet water flow must be at least 125% of pump rated flow (see the following table). Check volume by timing how long it takes to fill a 20 litre container For example, a flow rate of 10 L /min would fill a 20 litre container in 2 minutes.

3. Water supply hose should be a good grade of garden hose with a minimum inner diameter of 12mm, and no longer than 15m. If a longer supply hose must be used, check to be certain flow is at least equal to the ‘Umin Supply Required value for your washer (See the following table).

4. If a non-pressurised (static draw) water supply is used, check to be certain flow is at least 125% of pump rated flow (see the following table).
   In static draw situations, water flow rate (L/min) can be increased by elevating the water supply tank or changing to a larger inside diameter water supply hose.

5. Adding on extension to the supply hose will reduce water flow rates. Check for adequate water flow rate each time an extension is added. Water flow rates can be increased by using the largest possible internal diameter supply hose.

IMPORTANT: Inlet water temperature must not be more than 40°C or damage to the pump may result.

Cleaning & Applying Chemicals

CAUTION: You must attach all hoses before you start the engine. Starting the engine without all the hoses connected and without the water turned ON will damage the pump. Damage to equipment resulting from failure to follow this instruction will void warranty.

IMPORTANT: Use soaps designed specifically for pressure washers. Household detergents could damage the pump.

To apply detergent follow these steps:

1. Review spray tip use.

2. Prepare detergent solution as required by manufacturer.

3. Place chemical injection siphon/filter into detergent container.

4. Make sure black spray tip is installed.
   NOTE: Detergent cannot be applied with the high pressure spray tips (White, Green, Yellow, or Red).

5. Make sure garden hose is connected to water inlet.
   Check that high pressure hose is connected to spraygun and pump; start engine.

6. Apply detergent to a dry surface, starting at lower portion of area to be washed and work upward, using long, even, overlapping strokes. DO NOT allow detergent to dry on (prevents streaking).

7. Allow detergent to soak in between 3-5 minutes  before washing and rinsing. Reapply as needed to prevent surface from drying.

CAUTION: Keep the chemical injection tube from coming in contact with the hot muffler. When inserting the filter into a detergent solution bottle, route the tube so as to keep it from inadvertently contacting the hot muffler.

Pressure Washer Rinsing

After you have applied detergent, scour the surface and rinse it clean as follows:

1. Apply safety latch to spray gun.
2. Remove black chemical spray tip from nozzle extension.
3. Select and install desired high pressure spray tip following instructions in ‘How to Use Spray Tips’
4. Apply high pressure spray to small area and check surface for damage. If no damage is found, you can assume it is okay to continue cleaning.
5. Start at top of area to be rinsed, working down with same overlapping strokes as you used for cleaning.

Thermal Relief
A NEVER allow the pump to run for more than a 2 minute period without opening the gun. This will cause the pump damage due to excessive water temperature and void the warranty. A thermal relief valve has been added to the pump to reduce the possibility of overheating, however, malfunction of this device does not constitute pump warranty for damage caused by overheating.

Cleaning Horizontal Surfaces

1. Move nozzle wand from side to side. Direct spray at an angle to force debris ahead and away from the cleared area (Fig. 7 ).
2. Depending on the material to be removed and nozzle pressure, hold nozzle end 20 to 25cm from the surface and use slow, overlapping strokes.
3. If debris is easy to remove, move nozzle back to cover more area for faster cleaning.

Cleaning Vertical Surfaces

IMPORTANT: Remember that the washer can deliver a high pressure spray that can break glass and gouge soft wood and other materials.
When cleaning building interiors or exteriors without detergents, work from top to bottom. This will help eliminate streaks. In interiors, start with the ceiling first, then the walls and the floor last.

CAUTION! Clean around windows carefully. If glass panes are not well- caulked and puttied, the high pressure spray could break the glass.

• Never spray directly overhead. Always spray ahead to avoid dripping or falling debris.

Removing Paint

IMPORTANT: Remember that high pressure spray can gouge soft woods and other materials, as well as loosen grout.

1. Direct spray at a 45° angle about 10 to 30cm from surface.
2. Spray in a back and forth motion, try to get beneath the loose and bubbled paint.
3. Do not be concerned with the paint that remains. It should be sufficiently bonded so as not to cause repainting problems.
4. Some remaining paint may curl up at the edges. These edges should be scraped with a steel brush or scraper just before painting.

Cleaning Radialor Fins

IMPORTANT: Some engine and radiator manufacturers may not permit cleaning radiators with a high pressure washer – refer to the equipments Operating Manual.

1. Use clean water without detergent.
   IMPORTANT: Spray straight into the radiator to prevent bending fins.

2. If possible, direct spray in the direction opposite to normal air flow through the radiator.

General Maintenance

The pressure washer warranty does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain the pressure washer as instructed in this manual.

• Some adjustments will need to be made periodically to properly maintain your pressure washer.
• All maintenance in this manual should be made at least once each season.
• If equipped with inflatable tires, keep the air pressure at the value marked on the tyre or within 15 and 40 psi.

Before Each Use:

1. Check engine oil level.
2. Check water inlet screen for damage.
3. Check high pressure hose for leaks.
4. Check detergent siphoning tube and filter for damage.
5. Check spray gun, nozzle extension, and spray tips for leaks.
6. Rinse out garden hose to flush out debris.

Check and Clean Inlet Screen
Examine the screen on the water inlet. Clean it if the screen is clogged or replace it if screen is damaged.

Check High Pressure Hose
The high pressure hose can develop leaks from wear, kinking, or abuse. Inspect the hose each time before using it. Check for cuts, leaks, abrasions or bulging of cover, damage or movement of couplings. If any of these conditions exist, replace the hose immediately.

WARNING! The high pressure stream of water that this equipment produces can pierce skin and its underlying tissues, leading to serious injury and possible amputation. NEVER repair high pressure hose. Replace it. Replacement hose rating MUST exceed maximum pressure rating of unit.

Check Detergent Siphoning Tube
Examine the filter on the detergent tube and clean if clogged. The tube should fit tightly on the barbed fitting. Examine the tube for leaks or tears. Replace the filter or tube if either is damaged.

IMPORTANT: Simply shutting OFF engine will not release pressure in the system. When the engine has shut down, squeeze the trigger on the spray gun to relieve the pressure in the hose.

Cleaning Detergent Siphoning Tube
If you used the detergent siphoning tube, you must flush it with clean water before stopping the engine.

1. Place chemical injection siphon/filter in a bucket full of clean water.
2. Attach black low pressure spray tip.
3. Flush for 1-2 minutes.
4. Shut off engine.

Check Gun and Nozzle Extension
Examine the hose connection to the spray gun and make sure it is secure. Test the trigger by pressing it and making sure it springs back into place when you release it. Put the safety latch in the on position and test the trigger. You should not be able to press the trigger.

3. Remove nozzle extension from spray gun.
4. Squeeze trigger on spray gun and hold.
5. When water supply is steady and constant, engage safety latch and reattach nozzle extension.

Nozzle Maintenance

A pulsing sensation felt while squeezing the spray gun trigger may be caused by excessive pump pressure. The principal cause of excessive pump pressure is a spray tip clogged or restricted with foreign materials, such as dirt, etc.

To correct the problem, immediately clean the spray tips using the tools included with your pressure washer and follow these instructions:

1. Shut off engine and turn off water supply.
2. Remove spray tip from end of nozzle extension.
3. Remove in-line filter from other end of nozzle extension.
4. Use wire included in kit (or a small paper clip) to free any foreign material clogging or restricting spray tip (Fig.10).
5. Using a garden hose, remove additional debris by back flushing water through nozzle extension (Fig.11 ). Back flush between 30 to 60 seconds.
6. Reinstall spray tip into nozzle extension.
7. Reconnect nozzle extension to spray gun.
8. Reconnect water supply, turn on water and start engine.
9. Test pressure washer by operating with each Quick Connect spray tip.

O-Ring Maintenance
Through the normal operation of your pressure washer, a-rings, which keep the connections of the hoses and spraygun tight and leak-free, may become worn or damaged. To remove a worn or damaged a-ring; use a small flathead screwdriver to get underneath the a-ring and pry it off.

Engine Maintenance
See the engine owner’s manual for instructions on how to properly maintain the engine.
KEEP OUT OF REACH OF CHILDREN. DON’T POLLUTE. CONSERVE RESOURCES. RETURN USED OIL TO COLLECTION CENTRES.
CAUTION! Avoid prolonged or repeated skin contact with used motor oil. Used motor oil has been shown to cause skin cancer in certain laboratory animals.

• The maximum engine RPM has been set at the factory. TAMPERING WITH ENGINE GOVERNOR WILL VOID WARRANTY.

Pump Maintenance
Check Oil Level

1. Holding pressure washer by it’s handle, drop the handle towards you and lower to the ground so that the pump head (D) is facing vertically towards the ground.
2. Undo the filler bung (A) anti-clockwise with a 14mm ring spanner. The oil level of the pump should be at the bottom thread of the bung hole (B).
3. If the oil is not at this level, tip the pump forward to the horizontal position and add SAE30 oil. Then tip back to vertical position to check level is at the bottom thread of the bung hole (B).
4. Re-thread in filler bung and tighten moderately with a spanner.

Oil Change Periods
The oil in the pump should be changed after the first two hours of use and then every 50 hours of use thereafter.

Changing the Oil
To change the oil, ensure machine is in it’s normal position.

1. Loosen the four bolts that fasten the pump to the engine (C).
2. Rotate the pump 180° on the shaft until the filler hole (A) is facing towards the ground.
3. Catch the oil in a plastic container.
4. Rotate pump back into position.
5. Replace the four pump bolts and tighten firmly.
6. Refill pump oil (SAE30) with funnel and replace the filler bung. Pump oil capacity= 140mls.

CAUTION! Do not exceed the manufacturer’s maximum pressure by increasing the unloader adjustment. (This will void pump warranty.)

Service Chart

1. Perform engine oil change after first 5 hours of use and then at recommended intervals. Change engine oil every 25 hours when used under heavy load or in high ambient temperatures.
2. Service more frequently when used in dusty areas.
3. Air filter element may require replacement earlier in dusty areas. A dirty air filter reduces engine performance.
4. Unit should be serviced by authorised dealer unless owner has proper tools and is mechanically proficient and experienced in the repair of pressure washers.

Storage
Water shouldn’t remain in unit for long periods of time. Sediments or minerals can deposit on pump parts and ‘freeze’ pump action. If you do not plan to use the pressure washer for more than 30 days, follow this procedure:

1. Flush detergent siphoning tube by placing filter into a pail of clean water while running pressure washer in low pressure mode. Flush for one to two minutes.
2. Shut off engine and let it cool, then remove high pressure and garden hoses. Disconnect spark plug wire from spark plug.
3. Empty pump of liquids by pulling engine recoil handle about 6 times. This should remove most liquid in pump.
4. Use pump saver to prevent corrosion build up and freezing of pump.

Protecting the Pump
To protect the pump from damage caused by mineral deposits or freezing, use PumpSaver to treat pump. This prevents freeze damage and lubricates pistons and seals.

NOTE: PumpSaver is available as an optional accessory. It is not included with the pressure washer. Contact the nearest authorized service center to purchase PumpSaver.
CAUTION! You must protect your unit from freezing temperatures. Failure to do so will permanently damage your pump and render your unit inoperable. Freeze damage is not covered under warranty.
To use PumpSaver, make sure the pressure washer is turned off and disconnected from supply water. Read and follow all instructions and warnings given on the PumpSaver container.
NOTE: PumpSaver will drip from pump after treatment and will stain wood and concrete.
CAUTION! Read and follow all cautions and ? warnings on the PumpSaver can label. Always wear eye protection when using PumpSaver.
NOTE: If PumpSaver is not available, draw RV anti­freeze (non-alcohol) into the pump by pouring the solution into a 1 metre section of garden hose connect­ed to inlet adapter and pulling recoil handle twice.

Troubleshooting

NOTE: Most problems with pressure washers are not a malfunction of the pump or motor!! ALWAYS trouble shoot from water source and/or nozzle towards the pump and motor. Example: Check water supply and nozzle if pressure fluctuates, unit is noisy or does not reach full pressure.
Follow these trouble shooting rules closely With proper care and use of the pressure washer, the unit should remain free of problems. Most problems are caused by careless or improper use of equipment. Operation of the unit without an inlet water supply will result in damage to seals and other components. Another common cause of damage is running unit for long periods with spray gun trigger in its “Closed” position. The latter can result in high water temperatures, resulting in damage to seals and other components.

Cavitation
If the water pressure falls below a certain point ( called vapor pressure) the water will begin to boil even though the temperatures are below normal boiling point. Tiny bubbles of vapor will then form in the boiling water. If the vapor bubbles are carried away to a higher pressure area in the system the vapor will condense again and leave a cavity in the midst of the flow. The surrounding water will then rush in to fill these cavities. Extremely high local pressures are then created (up to 100,000 PSI). Such high pressures may result in erosion, turbulence, noise, vibration, and excess wear and tear on the pump. The pump inlet, where the pistons pull the water in, is very susceptible to cavitation problems.

Anything that obstructs the flow of water into the pump can result in cavitation such as:

• A clogged water inlet filter
• Inlet piping or hoses that are too small
• Excessive numbers of restrictions in the water inlet (such as too many valves, or too many bends).
• Excessive turbulence or heat

Some Pressure Washer Problems

Some of the problems that might occur in a pressure washer system are as follows:

• Failure of the unit to produce pressure
• Erratic pressure
• Chattering
• Reduction in pressure
• Low water volume

When a problem arises don’t remove the pump immediately and start replacing parts.

First check the following possible causes of the problem:

• Make sure the water supply is turned on and the water supply is adequate.
• Make sure the water inlet hose is not kinked or damaged.
• Check the inlet water filter. Clean or replace if necessary.
• Make sure the water supply is not too hot. Inlet water temperature should not exceed 40° C.
• If a detergent is being used, make sure the detergent hose is submerged and not drawing air into the system. If detergent is not being used, the chemical injector valve should be turned off.
• Make sure the unloader/regulator valve is properly adjusted.
• Make sure the pump outlet hose is not leaking and is not blocked.
• Check the wand and high pressure hose quick couplers for missing 0-rings.
• Check that the nozzle is clear and unobstructed.

Problems with Detergent
Problems with use of detergent are often caused by incorrect procedures of operator. Problems encount­ered that involve the use of cleaning agents can often be attributed to one or more of the following:

1. Hose is not fully submerged in solution: If the tube isn’t fully immersed, the unit will be picking up air.
2. Injection valve is closed: The detergent valve must be open in order to pick up detergent.
3. Wrong type of detergent: Only soaps designed specifically for pressure washers should be used. Household detergents could damage the pressure washer.

Troubleshooting Tips

1. If the pump is running but produces no flow, try priming the pump.
   • To prime the pump, keep suction at a minimum and keep the discharge line open.
   • Open and close the spray gun trigger repeatedly to aid the priming process.
2. A chattering noise usually indicates a restricted water supply or air leaks.
   • Check for kinks or leaks in the hoses
   • Look for a plugged or damaged inlet water filter
   • If the filter has been damaged, sediment may have entered the pump. The sediment will be lodged in the inlet valve(s) and must be removed.
3. Damage to the pump can result from
   • Inadequate water supply,
   • Vacuum lift too high, or
   • Excessive water temperature.
4. Check the pump crankcase for correct oil level and for oil contamination. If oil appears milky, water has entered the oil and the piston seals should be replaced.
