4. Make the initial reel to bedknife adjustments
appropriate for backlapping on all cutting units. Start
the engine and set the engine to low idle speed.
5. Engage the reels by pulling out the knob on the
instrument panel.
6. Apply lapping compound with the long handled
brush supplied with the machine.
Contact with the reels or other moving parts
can result in personal injury.
• Keep fingers, hands, and clothing away from
the reels or other moving parts.
• Never attempt to turn the reels by hand or
foot while the engine is running.
7. To make an adjustment to the cutting units while
backlapping, turn the reels off by pushing in on the
knob on the instrument panel and turning the engine
off. After adjustments have been completed, repeat
steps 4 through 6.
8. When the backlap operation is completed, stop the
engine, rotate the backlap knob to the Forward (F)
position, set the reel speed controls to the desired
mowing setting and wash all lapping compound off
of the cutting units.
Note: Additional instructions and procedures on
backlapping are available in the Toro Sharpening Reel &
Rotary Mowers Manual, Form No. 80-300SL.
Note: For a better cutting edge, run a file across the
front face of the bedknife when the lapping operation is
completed. This will remove any burrs or rough edges
that may have built up on the cutting edge.
Storage
Preparing the Traction Unit
1. Thoroughly clean the traction unit, cutting units,
and engine.
2. Check the tire pressure. Inflate all traction unit tires
to 16 to 20 psi (110 to 138 kPa).
3. Check all fasteners for looseness and tighten them
as necessary.
4. Grease all grease fittings and pivot points. Wipe up
any excess lubricant.
5. Lightly sand and use touch-up paint on painted areas
that are scratched, chipped, or rusted. Repair any
dents in the metal body.
Storing the Battery
Charging the battery produces gasses that can
explode.
Never smoke near the battery and keep sparks
and flames away from it.
If the machine will be stored more than 30 days, prepare
the battery as follows:
1. Remove the battery terminals from the battery posts
and remove the battery from the machine.
2. Clean the battery, terminals, and posts with a wire
brush and baking soda solution.
3. Coat the cable terminals and battery posts with
Grafo 112X skin-over grease (Toro Part No. 505-47)
or petroleum jelly to prevent corrosion.
4. Slowly recharge the battery every 60 days for 24
hours to prevent lead sulfation of the battery. To
prevent the battery from freezing, make sure it is
fully charged. The specific gravity of a fully charged
battery is 1.265 to 1.299.
5. Either store the battery on the shelf or on the
machine. Leave the cables disconnected if it is stored
on the machine. Store it in a cool atmosphere to
avoid quick deterioration of the charge in the battery.
Preparing the Engine
1. Drain the engine oil from the oil pan and replace
the drain plug.
2. Remove and discard the oil filter. Install a new oil
filter.
