***The difference between this unit and the is the unloader block mounted ZK7.3 unloader connected by high pressure hoses on this unit***** It is the Cadillac of set-ups and worth not fighting your hose.

Super skid hot skid power washer 8 GPM 3500 psi plumbed on an unloader block with the zk7.3 flow sensitive unloader.

To order this unit, please add to cart and choose local pick up. We use Estes express to ship to your door. We ship this unit FREE to the lower 48 States in the USA. We stock this unit normally.

Must tighten belts after 30 days. No warranty on belts. Unloader settings, clogged nozzles and loose belts are some causes of belt failure.

This powerful, time saving hot skid unit will arrive with a 1" hose barb on the inlet of the pump. We strongly recommend that you purchase our pl-8-to or pl-8-ta kit which has everything you need to correctly plumb this unit. We recommend switching out the 1" barb to 1.5", upsizing the non-collapsible suction hose to 1.5" id, upsizing the filter to 80 mesh 1.5", installing a 1.5" bulkhead, brass hose barb and 1/2" bulkhead. Increase the jump hose to the reel to a 1/2" high pressure hose and use a 50' hose as the first length of hose on the reel. (Always strip all hose from the reel when in use.) Upsizing the hose ID's will allow you to shoot farther, increase the cleaning units and efficiency on your pressure washer as well as move much faster when using your surface cleaner. The pl-8-ta or pl-8-to kit has everything you need to plumb the pressure washer as well as connect to a reel including the 50' high-pressure hose.

Upsizing your hoses will prevent back-pressure to your pump, help your valves and high-pressure seals last longer, prevent your safety relief valve from spraying, supply enough water to your pump using the 'double your supply hose id in relation to your inlet port' rule and keep your pump cooler leading to less down time. Double check your surface cleaner hose to ensure that it is 3/8" id instead of 1/4". Always use medium threadlock on your high pressure fittings instead of Teflon tape. Teflon tape will end up in the pump valves or clog nozzles.

Are you tired of releasing the gun trigger to watch pressure build up in the high pressure hose, gun, wand, quick connects and O-rings?

Tired of your pump going into bypass because another O-ring failed and you need to replace the plug and/or coupler?

Do you want a smooth action when you pull your gun trigger?

Are you struggling with moving your stiff pressure washer hose?

Do you need to place a death grip on your ladder when you pull the trigger on your gun to prevent falling?

This super skid is plumbed with the 'Cadillac of unloaders', the k7.3 flow sensitive unloader. Everything under pressure lasts longer. It is plumbed remotely on an unloader block using 1/2" id high pressure hoses. This is the ultimate skid.

If using a chemical injector, install the injector only when in use and install it several feet downstream of the unloader to prevent back-siphoning into the unloader/pump manifold.

Regarding k7 or flow actuated unloaders: the normal operating rpm on most Honda engines is between 2000-3900. If you run them lower than 2000 for extended periods of time, the combustion chamber will carbon up with unburned fuel and foul the spark plugs (per Honda). The k7 needs full throttle.

Note: all units are completely factory assembled, tested in the USA, and delivered ready to operate

Wonder what the difference is between a hot box and a super skid? We asked Bill Matthews from pressure pro. His response is copied below:

As for the burner efficiency, they would be within only a few percent of each other typically in the upper 70-80 percent range (roughly 76-82%).

The best comparison you made would be that the fuel capacity is diminished for the hot box by 31% and for the gas engine by 50%.

One advantage would be that the HBS12V80 has a slightly larger coil and would allow for a slightly larger heat rise roughly 10° but would consume roughly .7 gph more fuel.

8012PRO-35HG 2.8 gph diesel (approx 170°) (12-gallon tank approx 4.28 hrs)

Honda GX690 1.8 gph gas (12-gallon tank approx 6.66 hrs)


HBS12V80 3.5 gph diesel (approx 180°) (8.5-gallon tank approx 3.03 hrs)

Honda GX690 1.8 gph gas (6-gallon tank approx 3.33 hrs)

Both motor pump configurations are virtually identical.

We recommend the Whisper Wash 19" classic (4345), 24" ground force (6715), 24" Lil' Big Guy or maybe the 28" Big Guy for use with this 8 GPM hot skid. Using a larger diameter surface cleaner will cause the user to move more slowly than if using the 19"-24" unit.

We strongly recommend that you add a 6540-8 Jrod kit & the Kyle Davis long range shooter nozzle (SN8I).

To order this unit, please add the the cart. We ship this unit free to the lower 48 States in the USA.
