How to fix Yard-Man YM1500 Trimmer if engine will not start?

  Daniel PrattAug 4, 2025
  If your Yard-Man Trimmer engine won't start, first, ensure the On/Off control is in the ON position. Then, check the fuel tank and fill it with properly-mixed fuel if it's empty. If the tank isn't empty, try pressing the primer bulb fully and slowly 10 times. If it still doesn't start, the engine may be flooded; use the starting procedure with the choke lever in the RUN position. Also, old or improperly mixed fuel can be a culprit, so drain the gas tank and add a fresh fuel mixture. Finally, check the spark plug and replace or clean it if it's fouled. If none of these steps work, the spark arrestor might be plugged, so clean or replace it.

  Alyssa ColeAug 9, 2025
  If your Yard-Man Trimmer engine lacks power or stalls when cutting, the issue could be due to several factors. Start by draining the gas tank and adding a fresh fuel mixture, as old or improperly mixed fuel is a common cause. If the problem persists, the carburetor might need adjustment, which should be done by an authorized service dealer. Additionally, inspect the spark plug and clean or replace it if it's fouled. Lastly, check the spark arrestor; if it's plugged, clean or replace it.

  Jessica MurphyAug 13, 2025
  If your Yard-Man Trimmer engine will not accelerate, start by draining the gas tank and adding a fresh fuel mixture, as old or improperly mixed fuel can cause this issue. If that doesn't solve the problem, the carburetor may need adjustment, which should be done by a qualified service dealer. Also, check the cutting attachment; if it's bound with grass, stop the engine and clean it. A dirty air filter can also cause acceleration problems, so clean or replace it. Lastly, a plugged spark arrestor could be the culprit, so clean or replace it.

  If your Yard-Man Trimmer engine won't idle, the air filter may be plugged; try replacing or cleaning it. Also, old or improperly mixed fuel can cause idling issues, so drain the gas tank and add a fresh fuel mixture. If these steps don't resolve the problem, the carburetor may need adjustment; refer to the Carburetor Adjustment section for instructions.

What to do if cutting attachment will not advance line on Yard-Man YM1500 Trimmer?

  Michael EspinozaOct 29, 2025
  If the cutting attachment on your Yard-Man Trimmer will not advance the line, there are several potential causes. First, stop the engine and check if the cutting attachment is bound with grass, and clean it if necessary. If that's not the issue, the cutting attachment might be out of line, so refill it with a new line. The inner reel could also be bound up, in which case you should replace it. Additionally, a dirty cutting head can prevent line advancement, so clean the inner reel and outer spool. Other possible issues include a line that is welded (disassemble, remove the welded section, and rewind) or twisted when refilled (disassemble and rewind the line). Finally, ensure that enough line is exposed by pushing the bump knob and pulling out the line until 4 inches (102 mm) of line extend...
