Drive Belts; Cutter Blades - Scag Power Equipment STT Operator's Manual

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.

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.

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:
Always wear proper hand and eye protection
when working with cutter blades.
3. Check the cutter blades for straightness. If the
cutter blades appear bent, they will need to be
replaced.
WARNING:
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.
4. If a blade cutting edge is dull or nicked, it should be
sharpened. Remove the blades for sharpening. See
"Blade Replacement."
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.
B. Blade Sharpening
If possible, use a file to sharpen the blade.
Using a wheel grinder may burn the blade.
DO NOT sharpen the blades beyond 1/3 of the
width of the blade.
1. Sharpen the cutting edge at the same bevel as the
original. See Figure 7-7. Sharpen only the top of the
cutting edge to maintain sharpness.
