Maintenance Instructions CLEANING

NOTE: While some degree of material buildup in the mower deck housing can be tolerated, a point is finally reached where cutting quality deteriorates and clogging begins to occur because of too much buildup on the baffling and housing.

4.Lower the deck to the normal operating position and re-engage the deck lock levers.

CAUTION

Do not operate machine with deck tilt-up pivot joint unlocked.

GHS Blower

Normally, the GHS blower operates with no mainte- nance or cleaning. However, when mowing grass that is dirty and damp (especially springtime mow- ing), a deposit of dirt may accumulate inside the blower housing, causing wear and binding of the blower wheel. When operating in these conditions,

inspect the blower frequently for dirt buildup.

NOTE: A visual clue of binding of the blower wheel is the blower blade tips are polished from rubbing on dirt.

When a dirt deposit is found, use a high pressure washer or water spray to clean the inside of the housing as follows:

DANGER

Before attempting to wash the blower, stop the engine, remove the ignition key, and disconnect the spark plug wires.

1.Remove the GHS blower drive belt by unhook- ing the belt tension spring from the hook on the chassis frame (located above the blower pul- ley). Lift the belt tightener idler pulley up and roll the belt off of the blower pulley. The belt should be clear of the blower pulley, allowing free movement of the blower wheel.

IMPORTANT: With the belt removed, the blow- er wheel must spin freely. Any binding or drag- ging of the wheel is an indication of dirt buildup. This buildup must be cleaned to avoid abrasive wear of the blower blades, ex- cessive power loss and eventual loss of blower performance (clogging).

2.Use a pressure washer or water spray, and di- rect the spray inside the blower housing against the blower blades. Water pressure will cause the blower wheel to begin to spin and the com- bination of spinning action and water will effec- tively wash the inside of the housing. Spray may be directed against the blower blades vertically and horizontally to cause rotation in both direc- tions for thorough washing action. Wash blow- er until the blower wheel spins freely in both directions.

3.Reinstall the GHS blower drive belt by reversing the removal procedure.
