Operation Guide for the Scag Giant-Vac YV14-EA190

Ready to put Scag’s YV14-EA190 Yard Vac to work? These tips will help you keep yourself safe, keep your vacuum running and keep your yard clean and tidy.


These vacuums should be handled the same way you would any other power equipment. Always remember to keep body parts away from moving or hot parts, shut off the engine in confined spaces, and only operate it if you fully understand the controls. There are also a few unique safety precautions you should take into consideration:

  • Always wear hearing, vision and breathing protection.
  • Never vacuum burning material.
  • Always make sure the debris bag and adapter are properly installed. Shut off the engine and let it come to a complete stop before removing the bag.
  • Never attempt to repair the blower fan. If it’s damaged, it must be replaced.

Before Starting

Always check the engine oil level before using this vacuum. To find out how to check the oil and which oil your vacuum’s motor uses, consult the included engine manual.

Starting the Engine

  1. More the vacuum to a flat, open area.
  2. Move the fuel control lever, located on the left side of the motor, to “open.”
  3. Make sure the debris bag and bag adapter are installed. If they aren’t, the interlock switch won’t allow the engine to run.
  4. Set the engine throttle control, located on the left side of the handle, all the way forward to “choke” if the engine is cold. If you’re restarting the engine, move it to the center for half engine speed.
  5. Give the recoil starter a quick pull.
  6. Let the engine warm up, then set the throttle speed before vacuuming.


This vacuum can handle a small amount of sand, glass and bottles, but these materials will accelerate wear, especially on the impeller and bag.

To get maximum debris pickup, set the throttle to “full” and adjust the height of the inlet so that it’s as close as possible to the debris while still allowing some airflow. The height control lever is located on the left side of the handle. When operating in dusty areas, set the throttle to “slow.” If the pores in the bag are plugged with fine dust, shut off the engine and open the zipper on the side of the bag to expose more venting surface. Start the engine and resume vacuuming.

The vacuum depends on maintaining steady airflow from the nozzle through the impeller and bag. The debris bag needs to be clean and the top zipper fully closed, and the accessory plug should be covering the front hole of the vacuum nozzle. After washing, always let the bag dry completely before using. If the bag is nearly full, airflow can be restricted, hindering performance.

If the intake or discharge become plugged, shut off the engine and disconnect the spark plug wire to prevent accidental starts. Let the engine come to a complete stop before removing the debris bag or cleaning out the inlet or discharge area. Use a stick to dislodge the material. Once the vacuum has been cleared and the debris bag refitted, reattach the spark plug wire and resume vacuuming.

Slow down when vacuuming heavy or large amounts of material, or when moving across a slope. Keep movements gradual when working on slopes and be aware of your footing, especially on wet grass. Don’t turn on a slope unless necessary. If possible, start at the top and work downward.

When parking the vacuum, leave it on a flat, level surface. Always stop the engine when leaving the vacuum.

After Operation

After the engine has cooled down completely, wash the entire machine to remove dust: too much dirt buildup can cause the engine to overheat. Never use a high-pressure sprayer, and never aim water at electrical components.

If the vacuum must be cleaned while hot, used compressed air. The engine could be damaged if it comes in contact with cold water while it’s still hot.
