Remove Cooling Shroud and Remove Debris (Z735E and Z735M)

Avoid Injury! Compressed air can cause debris to fly a long distance.

  • Bystanders should avoid work area.
  • Wear eye protection when using compressed air for cleaning purposes.
  • Reduce compressed air pressure to 210 kPa (30 psi).

Avoid machine damage! To ensure proper cooling, keep the engine cooling fins and surrounding area clean always. Operating the engine with obstructed cooling fins could cause engine damage due to overheating.

  1. Park machine safely. (See Parking Safely in the SAFETY section.)

  2. Allow engine to cool.

  3. Clean external engine surfaces.

  4. Remove air cleaner cover and air filter. (See Checking and Replacing Air Filtration System (Briggs & Stratton Engine) in the SERVICE ENGINE section.)

    Remove the drain hose (J).


  12. Remove two shroud bracket bolts (K).

  13. Lift shroud (L) upward and remove from engine compartment.

  14. Clean debris from:

    • Fan areas
    • Cylinder head
    • Cooling fins
    • Area between engine and frame
    • Oil cooler (if equipped)

  15. Install shroud, fuel pump, and drain hose respectively.

    Engine shroud must be assembled so that the slots in the shroud align with the ridge in the air intake and mating surfaces along sides of engine. Failure to assemble correctly prevents the air filter from sealing and may cause engine damage.

  16. Install grass cutter with four bolts (C).

  17. Install rotating screen guard with four bolts (A).

  18. Install air filter and air cleaner cover. (See Checking and Replacing Air Filtration System (Briggs & Stratton Engine) in the SERVICE ENGINE section.)
