Troubleshooting and Maintenance Guide for the JCB-WP80T Petrol Trash / Dirty Water Pump

Maintenance & Care

Maintenance – Sediment Filter:

Move the fuel valve to the OFF position, then remove the fuel sediment cup by twisting it off. Also remove the O-ring.

Wash the sediment cup and O-ring in a 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.

Maintenance - Spark Plug:

Recommended Spark Plugs – F7TC/F7TRC This variation of spark plug is recommended for normal engine running conditions and temperatures. Incorrect specifications of sparkplug can cause damage to your machine. Ensure any spark plug is correctly gapped and free of any deposits.

Firstly remove the Spark plug cap. This is a push/pull fit.

Using a suitable spark plug wrench, loosen the spark plug and remove it.

Inspect the sparkplug. Replace if your inspection finds: 1. Visible Damage 2. Badly fouled with Oil/Carbon 3. Washer health is compromised

Using a feeler gauge, check the gap of the spark electrode. The gap should be with these tolerances 0.7-0.8 mm (0.026-0.031 inch).

Reinstall the sparkplug, firstly winding it by hand, this is to avoid cross threading.

After properly seated, fully tighten using spark plug wrench.

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 - 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 suitable container below the engine to catch the used oil.

Remove the oil filler cap/dipstick, oil drain plug and washer.

Allow the used oil to drain completely.

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. We suggest you take used oil in a sealed container to your local recycling centre or service station for reclamation. Do not throw it in the General Waste, pour it on the ground, or down a drain.

With the engine in a level position, fill to the upper limit mark (bottom edge of the oil fill hole) on the dipstick with the recommended oil.
