BACKLAPPING AND GRINDING ______________________________________________
Check for damage to the bedknife and reel blades. Refer
to (Section 3.2).
1.
Determine if backlapping or grinding will restore the
proper cutting edge.
2.
For optimum performance use a bedknife grinder to
touch-up the blade then reassemble and adjust the
bedknife to the reel as described in (Section 3.2).
3.
Remove shaft cover from right side of reel and
assemble a 3/8-24 bolt and locknut to the end of the
shaft.
a.
Apply lapping compound with a long handle
brush along the entire length of the reel, (180 grit
is recommended, Section 2.6).
b.
Continue lapping and at the same time make a
fine adjustment on the reel and bedknife until
there is a uniform clearance along the full length
of the cutting edges.
4.
Carefully and thoroughly remove all lapping
compound from reel and bedknife
before running
the reel in forward direction
.

STORAGE ________________________________________________________________
General
1.
Wash the mower thoroughly and lubricate. Repair
and paint damaged or exposed metal.
2.
Inspect the mower, tighten all hardware, replace
worn or damaged components.
3.
Clean the tires thoroughly and store the tractor on
the kickstand so the load is off the tires. The front
roller or Turf Groomer should be resting on a wood
board.
4.
Keep the machine and all its accessories clean, dry
and protected from the elements during storage.
Never store equipment near an open flame or spark
which could ignite fuel or fuel vapors.
Engine
1.
While the engine is warm, remove drain plug and
drain the oil from the crankcase. Install drain plug
and refill with fresh oil. Torque drain plug to 22 ft. lb.
(30 Nm).
2.
Clean exterior of engine. Paint exposed metal or
apply a light coat of rust preventative oil.
To prevent the build-up of gum residues and vanish
films, fill the tank with stabilized fuel. Use an anti-
oxidant fuel conditioner, such STA-BIL®. Read and
follow the instructions on the container.
Operate the engine for about 5 minutes to distribute
the treated fuel. Stop the engine, close the fuel shut-
off valve and let the engine cool. Drain fuel.
3.
Remove the spark plug and pour about one ounce
of SAE 30 oil into the cylinder. Crank engine slowly
by hand to distribute oil over the cylinder wall.
Replace the spark plug.
4.
Pull the starter rope slowly until resistance is felt.
Continue pulling until the notch on the starter pulley
aligns with the hole on the recoil starter. At this
point, the intake and exhaust valves are closed.
Reel and Bedknife
1.
Wash the reel and bedknife thoroughly, then repair
and paint any damaged or exposed metal.
2.
Lubricate all fittings and friction points.
3.
Backlap the reels then back the reel away from the
bedknife. Apply a light coat of rust preventative oil to
the sharpened edges of the reel and bedknife.
After Storage
4.
Check or service air cleaner.
5.
Check oil level in the engine crankcase.
6.
Fill the fuel tank with fresh fuel. Open fuel shut-off
valve.
7.
Make certain that the tires are properly inflated.
8.
Remove all oil from the reels and bedknife. Adjust
bedknife and cutting height.
9.
Start and operate the engine at 1/2 throttle. Allow
enough time for the engine to become properly
warmed and lubricated.
CAUTION:
To prevent personal injury and damage
to the cutting edges, handle the reel with extreme
care.
WARNING
Never operate the engine without proper ventilation;
exhaust fumes can be fatal when inhaled.
