JCB-PW15040P Troubleshooting and maintenance

Pre-Operation Checks

 

• Connect Water supply to Inlet (1). Ensure there is 10ft of unrestricted hose feeding the machine, this allows for adequate flow.
• Turn on the water supply
• Connect the High pressure hose to the pump outlet (2).
• Adjust the outlet pressure using the Pump Regulating Valve (3)

Starting

Once the machine has been correctly setup with both Pre-Operation checks and water supply, the machine can be started. This will start building pressure.

• Move the fuel valve lever to the ON position
• To start a cold engine, move the choke lever to the CLOSED position. To restart a warm engine, leave the choke lever in the OPEN position.
• Move the throttle lever away from the SLOW position about 1/3 of the way toward the FAST position.

NOTE*- IF your machine doesn’t have a Throttle Lever, it will have an automatically controlled throttle

• Turn the ignition switch to the ON position
• Pull the recoil starter grip lightly until resistance is felt, then pull it briskly. Do not allow the recoil starter grip to snap back against the engine. Return it gently to prevent damage to the starter.
• If the choke lever was moved to the CLOSED position to start the engine, gradually move it to the OPEN position as the engine warms up.
• Pump output is controlled by adjusting engine speed. Moving the throttle lever in the FAST direction will increase pump output, and moving the throttle lever in the SLOW direction will decrease pump output.

Stopping Operation

To stop the engine in an emergency, simply turn the ignition switch to the OFF position. Under normal conditions,use the following procedure.

• Move the throttle lever to the SLOW position.
• Turn the ignition switch to the OFF position.
• Turn the fuel valve lever to the OFF position.

After use, turn off the water supply.

Pull the handle before any disassembly, pressure can still be present within the lance.

Unlock safety lock

The trigger has an inbuilt Safety Lock Out. When not using the machine, to avoid accidental overspray, simply extend the Safety Lock Out. There is a slot which the Lock Out will sit within

Pressure Adjustment & Soap Function

• Place the Soap inlet, and inlet hose into your container with soap. Follow mix instructions supplied by the manufacturer of the soap. If no instructions, assume it requires no mixing.
• The Soap inlet will draw the detergent through the hose into the pump, passing it through the lance. Some aftermarket brands make Soap Bottles which are compatible with the Lance. If you wish to use one of these, there isn’t any benefit to additionally drawing soap through the pump as shown.
• Adjust Pressure using Pressure Regulating Valve

Maintenance Schedule

Maintenance - Oil Servicing

When changing a machines oil, run the machine for a few minutes. Warm oil will always drain faster and more through compared to oil that’s cold.

• Place a container below the engine to catch used oil.
• Remove the oil filler cap (dipstick), oil drain plug and washer.
• Reinstall the oil drain plug and new washer, and tighten the oil drain plug securely. Please dispose of used motor oil in a manner that is compatible with the environment. 

Oil Grade 

• Use 4-stroke motor oil that meets or exceeds the requirements for API service classification SJ, SL, or equivalent.
• Always check the API service label on the oil container to be sure it includes the letters SJ, SL, or equivalent. SAE 15W-40 is recommended for general use

Other viscosities shown in the chart may be used when the average temperature in your
area is within the indicated range.

Spark Plug :

Recommended Spark Plugs – NGK:BPR7ES/Champion:RN7YC

• Ensure any sparkplug is correctly gapped and free of any deposits.
• When the washer has started to compress tighten to the following instruction:
  1. New Sparkplug – a 1/2 Turn tight
  2. Re-used Spark Plug – a 1/8 to 1/4 Turn tight

Maintenance – Sediment Filter

• Move the fuel valve to the OFF position, then remove the fuel sediment cup by twisting off. Also remove the O-ring.
• Wash the sediment cup and O-ring in non-flammable solvent, and dry them thoroughly.
• Place the O-ring in the fuel valve, and install the sediment cup. Tighten the sediment cup securely.
• Move the fuel valve to the ON position, and check for leaks. Replace the O-ring if there is any leakage.
