Yard-Man 500 Manuel D’Utilisation

1.  Lubricate the pivot points on the blade control handle 

at least once a season with light oil. The blade 

control must operate freely in both directions. See 

Figure 5-1.

2.  If your mower is equipped with ball bearing wheels, 

lubricate at least once a season with a light oil, all 

other types require no lubrication. However, if the 

wheels are removed for any reason, lubricate the 

surface of the axle bolt and the inner surface of the 

wheel with light automotive oil.

3.  Lubricate the torsion spring and pivot point periodi-

cally with light oil to prevent rust. See Figure 5-1. 

4.  The transmission is pre-lubricated and sealed at the 

factory and does not require lubrication.

1.  Refer to the separate engine manual for engine 

maintenance instructions. 

2.  Maintain engine oil as instructed in the separate 

engine manual packed with your unit. Read and 
follow instructions carefully. 

3.  Service air cleaner every 25 hours under normal 

conditions. Clean every few hours under extremely 

dusty conditions.

4.  Clean the engine regularly with a cloth or brush. 

Keep the cooling system (blower housing area) 

clean to permit proper air circulation which is es-

sential to engine performance and life. Be certain to 

remove all grass, dirt and combustible debris from 

muffler area. 

The underside of the mower deck should be cleaned 
after each use to prevent a buildup of grass clippings, 
leaves, dirt or other matter. If this debris is allowed to 
accumulate, it will invite rust and corrosion, and may 
prevent proper mulching. 

The deck may be cleaned by tilting the mower and scrap-
ing clean with a suitable tool (make certain the spark plug 
wire is disconnected).

The rear flap is attached to the back of the mower deck. If 
the rear flap becomes damaged, replace it by cutting off 
the flat end of the wire rod which secures it to the deck 
using a pair of side-cutters. Attach the new rear flap using 
the new rod provided with the rear flap, bending the ends 
of the rod over to secure.

Periodically inspect the blade adapter for cracks, 

especially if you strike a foreign object. Replace when 

necessary. Follow the steps below for blade service:

1.  Remove the bolt and the blade bell support which 

hold the blade and the blade adapter to the engine 

crankshaft. See Figure 5-2.
