SERVICE

CLEANING

After each day's aerating, remove and thoroughly clean the tines.  Apply a light coating of oil to the tines to 
prevent rust.  Replace bent, broken or worn tines and reinstall the tines on the unit.  After the engine has 
cooled, clean the unit with water.  Keep the belts free of oil and dirt.

LUBRICATION

Lubrication Fittings - A:

  The Lawnaire 28 has 

eight  grease fittings.  (1) Front wheel pivot, (5) Pivot 
axle, (2) Differential.  Use a standard lithium based 
grease to lubricate all eight fittings after every eight 
hours of operation.  Wipe each fitting before and after 
lubricating.

Reversing Gear Boxes - B:

  Lubrication filled gear 

boxes should require no additional lubrication, add 
lithium based gun lubricant if required.

Transmission - C:

  Remove plug, fill to bottom of 

plug opening with 80-90W gear lube.

TRANSPORTING

Close the fuel shut-off valve before transporting.

Loading;

  When using ramps to load the unit for transporting, be sure all three wheels are supported by    

ramps.

Unloading;

  When using ramps to unload the unit, engage the dog clutch (lever down) to keep the unit    

from rolling down the ramp too quickly.

TIRE PRESSURE

NOTE

:  Improper inflation will shorten tire life  

considerably.

Check tire pressure before each days    

operation. Keep all three tires inflated to 14-16 PSI 
(97-110 kPa).

Use caution when inflating a tire, or bringing a low 
tire up to recommended pressure.  Use a pressure 
gauge to check the pressure in a partially inflated tire 
before connecting an air hose.  Due to the low air 
volume requirements of small tires, over-inflation may 
reached in a matter of two or three seconds, which 
may cause the tire to explode.
