Scag Power Equipment STT-31BSG Manuel D’Utilisation

Section 7

WARNING:

BATTERIES PRODUCE EXPLOSIVE
GASES. Charge the battery in a well
ventilated space so gases produced while
charging can dissipate.

Charging rates between 3 and 50 amperes are

satisfactory if excessive gassing or spewing of

electrolyte does not occur or the battery does not feel

excessively hot (over 125°F). If spewing or gassing

occurs or the temperature exceeds 125°F, the charging

rate must be reduced or temporarily stopped to permit

cooling.

C. Jump Starting

1. The booster battery must be a 12 volt type. If a

vehicle is used for jump starting, it must have a

negative ground system.

2. When connecting the jumper cables, connect the

positive cable to the positive battery post, then

connect the negative cable to the negative battery

post.

WARNING:

Always wear proper hand and eye protection
when working with cutter blades.

7.8 DRIVE BELTS

All drive belts are spring loaded and self-tensioning,

however after the first 2, 4, 8 and 10 hours of operation,

the belts should be checked for proper alignment and

wear. Thereafter, check the belts after every 40 hours

of operation or weekly, whichever occurs first.

-NOTE-

If you experience frequent belt wear or breakage,

see your authorized Scag service center for belt

adjustment.

7.9 CUTTER BLADES

A. Blade Inspection

1. Remove the ignition key before servicing the blades.

2. Raise the mower deck to the highest position. Place

the lanyard pin in the highest cutting height positon to

prevent the cutter deck from falling.

WARNING:

4. If a blade cutting edge is dull or nicked, it should be

sharpened. Remove the blades for sharpening. See

"Blade Replacement."

-NOTE-

Keep the blades sharp. Cutting with dull

blades not only yields a poor mowing job, but

slows the cutting speed of the mower and

causes extra wear on the engine and the

blade drive by pulling hard.

Do not attempt to straighten a bent blade, and
never weld a broken or cracked blade. Always
replace it with a new blade to assure safety.

B. Blade Sharpening

-NOTE-

If possible, use a file to sharpen the blade.

Using a wheel grinder may burn the blade.

-NOTE-

DO NOT sharpen the blades beyond 1/3 of the

width of the blade. See Figure 7-9, Page 33.

1. Sharpen the cutting edge at the same bevel as the

original. See Figure 7-9, Page 33. Sharpen only the

top of the cutting edge to maintain sharpness.

3. Check the cutter blades for straightness. If the

cutter blades appear bent, they will need to be

replaced.
