Review: Position of pump handle, & weight when full - Works well for spraying weeds. Found it comfortable but heavy when full. If you're used to a heavy back pack, then there shouldn't be a problem. Well padded shoulders & hips straps. Have only used it twice so far & worked perfectly. Have used something similar in the past. Pump handle sits at 90 degree angle to the pack & moves up & down from there. Review: Best Yet! - First use performed way beyond expectations. So much better than others i've used. Installation directions challenging. Watching a YouTube video instead which helped a lot more than the printed directions that came with the product. So easy to use, I prefer this over a battery powered one. ## Features - Deluxe harness with wide, padded shoulder straps that fit comfortably across the torso and curve to the contour of the user's body, an adjustable hip harness assists with weight distribution, relieving burden from the user's shoulders - Multiple nozzle tips are included for versatility in both application rates and patterns and can be stored in the waste belt - Shut-off with comfort grip handle and lock-on mechanism, can be easily operated with heavy-duty work gloves - 50 in. heavy-duty nylon-reinforced hose and strain relief system preventing the hose from kinking at the chemical exit point ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09TB7275W | | Best Sellers Rank | #158,087 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #753 in Lawn & Garden Sprayers | | Brand | DEWALT | | Brand Name | DEWALT | | Color | Yellow | | Customer Reviews | 4.4 out of 5 stars 165 Reviews | | Hose Length | 5 Inches | | Item Dimensions W x H | 9"W x 22"H | | Item Type Name | DEWALT Internal Piston Pump Backpack Sprayer, 4 Gallon | | Item Weight | 10.4 Pounds | | Manufacturer | The Fountainhead Group Inc. | | Manufacturer Part Number | 190652 | | Manufacturer Warranty Description | 3 year limited warranty | | Material | Nylon | | Material Type | Nylon | | Maximum Pressure | 150 Pound per Square Inch | | Model Name | DEWALT Internal Piston Pump Backpack Sprayer, 4 Gallon | | Model Number | DSXP190652 | | Power Source | manual | | Product Dimensions | 9"W x 22"H | | Style Name | Curve,Adjustable,Deluxe | | Tank Volume | 4 Gallons | | UPC | 841688006355 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** DEWALT - **Color:** Yellow - **Item Weight:** 10.4 Pounds - **Material:** Nylon - **Tank Volume:** 4 Gallons ## Images ![DEWALT Internal Piston Pump Backpack Sprayer, 4 Gallon - Image 1](https://m.media-amazon.com/images/I/51NmV2yGenL.jpg) ## Questions & Answers **Q: Is this sprayer powered by Dewalt 20 volt batteries?** A: It's a hand pumped device.
