Maintenance Instructions<br />
CLEANING<br />
NOTE: While some degree of material buildup<br />
in the mower deck housing can be tolerated, a<br />
point is finally reached where cutting quality<br />
deteriorates and clogging begins to occur<br />
because of too much buildup on the baffling and<br />
housing.<br />
4. Lower the deck to the normal operating position<br />
and re-engage the deck lock levers.<br />
GHS Blower<br />
CAUTION<br />
Do not operate machine with deck tilt-up<br />
pivot joint unlocked.<br />
Normally, the GHS blower operates with no maintenance<br />
or cleaning. However, when mowing grass<br />
that is dirty and damp (especially springtime mowing),<br />
a deposit of dirt may accumulate inside the<br />
blower housing, causing wear and binding of the<br />
blower wheel. When operating in these conditions,<br />
inspect the blower frequently for dirt buildup.<br />
NOTE: A visual clue of binding of the blower wheel<br />
is the blower blade tips are polished from rubbing<br />
on dirt.<br />
When a dirt deposit is found, use a high pressure<br />
washer or water spray to clean the inside of the<br />
housing as follows:<br />
DANGER<br />
Before attempting to wash the blower,<br />
stop the engine, remove the ignition key,<br />
and disconnect the spark plug wires.<br />
1. Remove the GHS blower drive belt by unhooking<br />
the belt tension spring from the hook on the<br />
chassis frame (located above the blower pulley).<br />
Lift the belt tightener idler pulley up and roll<br />
the belt off of the blower pulley. The belt should<br />
be clear of the blower pulley, allowing free<br />
movement of the blower wheel.<br />
IMPORTANT: With the belt removed, the blower<br />
wheel must spin freely. Any binding or dragging<br />
of the wheel is an indication of dirt<br />
buildup. This buildup must be cleaned to<br />
avoid abrasive wear of the blower blades, excessive<br />
power loss and eventual loss of blower<br />
performance (clogging).<br />
2. Use a pressure washer or water spray, and direct<br />
the spray inside the blower housing against<br />
the blower blades. Water pressure will cause<br />
the blower wheel to begin to spin and the combination<br />
of spinning action and water will effectively<br />
wash the inside of the housing. Spray may<br />
be directed against the blower blades vertically<br />
and horizontally to cause rotation in both directions<br />
for thorough washing action. Wash blower<br />
until the blower wheel spins freely in both<br />
directions.<br />
3. Reinstall the GHS blower drive belt by reversing<br />
the removal procedure.<br />
