GENERAL PRECAUTIONS

________________________________________________________

A qualified technician must always make the adjustments and do the maintenance. If the correct adjustments can not 
be made, contact your Jacobsen Dealer.

Inspect the equipment according to the maintenance schedule and keep complete records.

 a

Keep the equipment clean.

 b

Keep all moving parts correctly adjusted and lubricated.

 c

Replace worn or damaged parts before you operate the mower.

 d

Keep all fluids at the correct level.

 e

Keep the shields in position and all hardware tight.

 f

Keep the tires correctly inflated.

 g

When you make the adjustments or repairs, do not wear jewelry or loose fitting clothing.

Refer to the illustrations in the Parts Manual for the removal and assembly of parts.

When you discard hazardous materials (batteries, lubricants, fuel, anti-freeze), follow your local, state or federal-
recommended procedures.

7.2

ALTERNATOR BELT _______________________________________________________

Check And Adjust The Alternator Belt:

The alternator belt tension is adjusted to prevent the stress on the alternator 
bearings and to prevent movement on the alternator pulley. Check the belt 
tension at the center of the belt between crank shaft and alternator pulleys. A

 

deflection of 9/32 to 11/32 in. (7 to 9 mm) is needed at the center (B) with a

 

load of 22 lbs (10kgf/98N) for a new belt.

To adjust belt tension:

1.

Loosen the alternator bolt (A) and the pivot bolt below the alternator.

2.

Move the alternator to tighten or loosen the belt tension. 

3.

Tighten the bolts.

 

WARNING

Before you clean, adjust or repair this equipment, move the mow switch to the OFF position, lower front and rear 
cutting units to the ground, turn on the parking brake switch, stop the engine and remove the key.

Make sure the mower is parked on a solid and level surface. Never work on a mower that is lifted only by the jack. 
Always use the jack stands.
