Why OREC GRH537Pro Lawn Mower won't start?
- J
  Jennifer WilliamsAug 15, 2025
  If your OREC Lawn Mower isn't starting, several factors could be the cause. First, ensure the safety switch is in the start-up position. Next, if the engine is cold, make sure the choke lever is pulled out. Also, inspect the fuel tank for any impure deposits or water, and clean the fuel valve strainer. Check for air or water in the fuel delivery system, and replace any damaged parts. In cold weather, use the correct oil for the temperature. Finally, inspect or replace a defective spark plug or ignition coil.

What to do if OREC Lawn Mower has low power output?
- C
  Colleen MurrayAug 18, 2025
  If your OREC Lawn Mower's power output is low, there are several possible reasons. Check if the fuel level is low and refuel if necessary. A clogged air filter can also reduce power, so clean the air filter element. Using poor quality fuel can cause issues; replace it with good quality fuel. Ensure the choke is fully open by returning the choke bar completely. Lastly, check if the cooling system is clogged and clean around the recoil starter.
