  If your Mertz Construction Equipment engine loses power, consider these potential causes: * The engine load may be excessive. Try reducing the ground speed or the speed of any attachments. * A dirty air cleaner can also cause power loss. Clean the air filter housing and replace the filter elements. * Check the engine oil level in the crankcase and add the appropriate engine oil if it's low. Refer to the engine manual for oil specifications. * Ensure that cooling fins and air passages under the engine blower housing are free from obstructions. * The fuel injectors may be plugged or dirty. In this case, have the diesel fuel injectors serviced by your Authorized Service Dealer.

  If the starter on your Mertz Construction Equipment isn't turning the engine over, here's what you can check: * Ensure the auxiliary hydraulics lever is in the neutral position, especially if no hydraulically powered attachment is installed. Move the lever to neutral if necessary. * Check the battery. If it's dead, charge it. If it doesn't hold a charge, replace it. * Inspect the electrical connections for corrosion or looseness. Clean the battery terminals and cable clamps. If the cable clamps can't be properly cleaned, replace the connectors. * If the engine is in hydraulic lock due to a cylinder filled with fuel, allow the engine to cool before attempting this procedure. Remove the fuel injectors and turn the engine over to pump excess fuel from the engine cylinder.

  Sarah CameronNov 12, 2025
  If your Mertz Construction Equipment's engine won't start, starts hard, or fails to keep running, here are a few things to check: * Ensure the auxiliary hydraulics lever is in the neutral position, especially if a hydraulically powered attachment is installed. Move the lever to neutral if it isn't. * Make sure the fuel tanks are filled with diesel fuel. * Try cycling the glow plugs for about 10 seconds to see if that helps the engine start. * Check and replace the fuel filter if it is dirty or contaminated. * Also, inspect the air cleaner and replace the filter elements if it's dirty. If there is dirt, water, or stale fuel in the fuel system, drain the fuel tanks into an appropriate storage container, dispose of the bad fuel properly, and refill with fresh, clean fuel.
