Maintenance Schedule

A. Daily Checks

1.Before starting engine:

a.Check the fuel level.**

b.Check the fuel strainer water trap and drain off contaminants if present.

c.Check the engine oil level.**

d.Check the hydraulic oil level.

e.Check the hydraulic hoses for leaks, abra- sion, kinks, twists, or a flattened condition.

f.Check coolant level in overflow bottle and replenish as necessary.

g.Check the tires and tire pressure. Drive Tires: 10-12 psi.

Front Caster Wheels: 20-25 psi.

h.Check the spindle belt, the mower drive belt and the hydro drive belt.

i.Check the blades. Make sure they are sharp and that the blade securing cap screws are tight.

j.Check the cutting height.

2.When ready to start the engine:

a.Check the five safety switches for proper operation.

3.After mowing:

a.Clean the mower.

b.Clean the engine air screen.

c.Oil the wear points. Follow the Oiling Chart.

d.After the first five hours, Change the engine oil and engine oil filter.

B.Every 25 Hour Checks

1.Service the engine foam element air pre- cleaner.*

2.Grease the three spindle bearings.

3.Check the radiator screen and clean as nec- essary.

C.Weekly or Every 50 Hour Checks

1.Change the engine oil. Use Shell Rimula 15W-40. (Every 25 hours under heavy duty operation.)

2.Clean or replace the engine’s paper air cleaner element.*

3.Check the battery’s electrolyte level.

4.Clean the engine cooling fins and external surfaces.*

5.After the first 50 hours, change the hydraulic oil and the hydraulic oil filter. Change them every 500 hours thereafter. Use Shell Rimula 15W40 or equivalent.

6.Oil wear points. Follow the Oiling Chart.

7.Lubricate all grease fittings. Follow the

Lubrication Chart.

D.Every 100 Hour Checks

1.Change the engine oil filter. (Every 50 hours under heavy duty operation.)

2.Check the engine spark plugs.

E.Every 500 Hour Checks

1.Change the hydraulic oil and the hydraulic oil filter.

2.Change the fuel filter.

F.Yearly Checks

1.Check the oil in the hydraulic reservoir.

2.Check the air gap on the blade brake clutch (PTO Clutch) and if it exceeds 0.025” adjust to 0.015” - 0.022”.

Engine coolant: Use only Shell Dex-cool, extended life anti-freeze diluted with water to create a 50:50 mixture.

Hydraulic fluid: Use Shell Rimula 15W40 oil.

Engine Oil: Use Shell Rimula 15W40 oil.

Spindle Lubricant: Use only Shell Alvania RL 2 grease. This grease is an amber-colored grease designed for high speed bearing applications. It has a base oil viscosity that reduces running losses, has been formulated for low noise, has excellent corro- sion protection, and has excellent bearing lubrication.

General Purpose Lubrication: Use any NLGI grade 2 multi-purpose grease. Shell Albida EP2 is recom- mended. Shell Albida EP 2 is a red-colored multi- purpose grease designed for heavy-duty bearing applications. It has high base oil viscosity for mechanical stability, has been formulated for high load, low-speed applications, and has excellent lubri- cation and corrosion protection.

*Perform maintenance more frequently under dusty conditions.
