Drive Belts; Cutter Blades - Scag Power Equipment STTII-52V-26CH-EFI Operator's Manual

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.
B. 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.
- NOTE -
If you experience frequent belt wear or breakage,
see your authorized Scag service center for belt
adjustment.
WARNING
If the pump drive belt fails, steering control will be
lost which could result in serious injury or death.
Replace the pump drive belt as needed or every
400 hours / 2 years, whichever occurs first.

7.9 CUTTER BLADES

A. BLADE INSPECTION
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 position
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.
4. Check the cutter blades for wear. If any part of the
cutter blade is worn to 1/2 its original thickness,
replace the cutter blade.
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.
5. Check the cutter blades for gouges. If there are
gouges on the top or bottom surfaces of the cutter
blade, replace the cutter blade.
6. 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 by pulling hard.
B. BLADE SHARPENING
If possible, use a file to sharpen the blade. Using
a wheel grinder may burn the blade.
