We do not recommend 

the use of pressure 

washers or garden 

hose to clean your 

unit. These may cause 

damage to electric 

components, spindles, 

pulleys, bearings, or 

the engine. The use 

of water will result in 

shortened life and 

reduce serviceability.

1.  Always observe safety rules when performing  

any maintenance.

2.  The warranty on this lawn mower does not cover 

items that have been subjected to operator abuse 
or negligence. To receive full value from warranty, 
operator must maintain the lawn mower as  
instructed here.

3.  Changing of engine-governed speed will void  

engine warranty. 

4.  All adjustments should be checked at least once 

each season.

5.  Periodically check all fasteners and make sure these 

are tight.

1.  Lubricate pivot points on the blade control at least 

once a season with light oil. The blade control must 
operate freely in both directions. See Figure 5-1.

2.  Lubricate the wheels at least once a season with 

light oil (or motor oil). If  wheels are removed for any 
reason, lubricate surface of the pivot arm and inner 
surface of the wheel with light oil. See Figure 5-1.

3.  Lubricate the torsion spring and pivot point on the rear 

discharge door periodically with light oil to prevent 
rust. See Figure 5-1.

factory and does not require lubrication.

tion schedule and instruction for engine lubrication.
