Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.87 gallon.
Design & Handling
Thanks to its hand truck design and approximate dimensions of D23.6 x W19.7 x H40.3 in, the Powermate 7131 offers great mobility. The robust and sturdy welded steel frame offers longevity to the assembly. The foam-padded fixed handle adds to the 7131 convenience of transport, while offering a comfortable grip.
The majority of users will be able to maneuver this unit easily, it only weighs 57 lbs. Its 208 cc Generac engine and welded steel frame all add up to a substantial part of that weight. The 7131 can still be easily manipulated and maneuvered, thanks to its two 10" never-flat wheels.
The Powermate 7131 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: A safe detergent storage is facilitated by a 0.3 gal tank. However, since the Powermate 7131 does not feature a soap dilution mechanism, you'll have to make sure your detergent is correctly diluted before use. The detergent will be added automatically to the water when a soap nozzle is attached.
- Pressure hose: Using a set of convenient hooks, the included 30 ft ⌀0.3" high-pressure hose (3100 PSI rating) can be easily stored on the unit when it is not running.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
- Nozzles: The 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
