schedule and instructions for maximum safety
and best results.
– Park machine on level ground.
– Never allow untrained personnel to service ma-
chine.
– Adjust or repair only after the engine has been
stopped and the tines have stopped rotating.
– Guards should only be removed by a qualied
technician for maintenance or service. Replace
when work is complete.
– Replace parts if worn, damaged or faulty.
For best results, always replace with parts
recommended by the manufacturer.
– Disconnect battery or remove spark plug wire(s)
before making any repairs. Disconnect the nega-
tive terminal rst and the positive last. Reconnect
positive rst and negative last.
– Do not dismantle the machine without releasing
or restraining forces which may cause parts to
move suddenly.
– Provide adequate support for lifted machine or
parts if working beneath.
– Do not put hands or feet near or under rotating
parts.
– Clean up oil or fuel spillage thoroughly.
– Replace faulty mufers.
– To reduce re hazards, keep the engine, mufer,
battery compartment and fuel storage area free
of grass, leaves, debris buildup or grease.
Tines
– Tines are sharp and can
cut. Use extra caution when
handling. Wear appropriate
personal protective equip-
ment.
WARNING
FUEL
– Gasoline and diesel fuels are
ammable; gasoline vapors
are explosive. Use extra
care when handling.
– Store only in containers spe-
cically designed for fuel.
– When refueling or checking fuel level:
- Stop the engine and allow to cool;
- Do not smoke;
- Refuel outdoors only;

TRANSAXLE & HYDRAULIC OIL
Do not perform engine maintenance without the en-
gine off and spark plug wires disconnected.
- Check cold.
- Add 20w50 oil if necessary to the indicated level.
- Do not overll. When the oil warms up it ex-
pands. If overlled cold, the oil may overow at
operating temperature.
Change the transaxle oil after the rst 75-100
hours, then every 500 hours or yearly.
It is essential that the exterior of the transaxle be free
of debris, prior to uid maintenance.
1. Raise the machine on the built in jack stands.
See jackstands section pg. 19. Put an oil drain
pan under the hydraulic oil lter located under the
center of the machine. Remove the lter A. This
will drain the oil from the reservoir. Remove the
hose from the lter to each transaxle. Remove
the lter adaptor Cfrom each transaxle to drain
the transaxles. With another drain pan, drain the
remaining oil from the reservoir through the drain
Don the lower left side of the reservoir. Dispose
of the used oil and lter properly.
2. Apply pipe compound to the reservoir drain plug
and reinstall in the reservoir. Check the O-ring
seal on the lter adaptor. Replace the O-ring if
there are any nicks or cuts. Wipe the mounting
surface on each transaxle. Reinstall the lter
adaptors to the transaxles. Tighten until the
adaptor body contacts the transaxle mounting
surface. Wipe the lter head mounting surface.
Oil the gasket of a new hydraulic oil lter and
install on the lter head. Tighten 3-4 to 1 turn
past the point where the gasket contacts the lter
head.
3. Fill the reservoir with 20w50 (15w50 is accept-
able) motor oil to the top. (Approximately 4 qts.).
4. Have more oil ready. Start the machine and
watch the oil level in the sight tube on the
reservoir. Add oil as the level drops below the
"FULL COLD" mark. Run the machine until the
oil level stabilizes.
5. Purge the transaxles, following the purging pro-
cedures. See Purging Transaxles Page 24.

specications. Do not overll.
3. Replace dipstick before starting engine.
PERIODIC OIL CHANGES
1. See engine manual for oil and lter change inter-
vals after the break-in period.
2. Follow instructions for rst oil change, above.
SPARK PLUGS
Remove each plug and check condition.
– Good operating conditions are indicated if the plug has a light coating of grey or tan deposit.
– A white blistered coating indicates overheating. A black coating indicates an “over rich” fuel mixture. Both
may be caused by a clogged air cleaner or improper carburetor adjustment.
– Do not sandblast, wire brush or otherwise attempt to repair a plug in poor condition. Best results are
obtained with a new plug.
– Set plug gap as specied in engine manual.
FUEL FILTER
An in line fuel lter is located in the fuel supply line. Inspect at every oil change to make sure it is clean and
unobstructed. Replace if dirty.

SA-30 MAINTENANCE
PURGING TRANSAXLES
Due to the effects air has on efciency in hydrostatic
drive applications, it is critical that it be purged from
the system.
These purge procedures should be implemented any
time a hydrostatic system has been opened to fa-
cilitate maintenance or any additional uid has been
added to the system.
Purging may be required if the unit shows any of the
following symptoms:
- Noisy operation.
- Lack of power or drive after short term use.
- High operation temperature, excessive oil
expansion.
1. Check the transaxle uid, ll to proper level, if
required.
2. Raise the drive wheels off the ground. Support
unit with jack stands or other suitable means.
3. With the bypass valve open, and the engine
running, slowly move the control levers in both
forward and reverse directions 5 to 6 times. As
air is purged from the unit, the oil level will drop.
4. With the bypass valve closed, and the engine
running, slowly move the control levers in both
forward and reverse directions 5 to 6 times.
5. Stop engine. Check the transaxle uid level, add
uid as required.
6. It may be necessary to repeat steps 3-5 until all
the air is completely purged from the system.
When the transaxle moves forward and reverse
at normal speed, purging is complete.
7 .Lower the machine from the jack stands, Stop
the engine and pin the jackstands in the operat-
ing position.
ENGINE COOLING
Continued operation with a clogged cooling system
will cause severe overheating and can result in en-
gine damage.
- Daily: Clean air intake screen Son air cooled
engines.
- Every 100 hours: Clean cooling ns beneath
blower housing Hwith reference to information in
the engine manufacturer's manual.
TINES
Tines can be sharp. Wear gloves when working
around tines to help prevent inadvertent injuries.
Tines:
– Replace damaged or broken tines.
– Do not weld or straighten tines.
– Clean tines after use, inside and out.
– Apply a light coat of oil to tines to prevent rusting.

MAINTENANCE
CLEANING MACHINE
Clean the machine after use. Compressed air is
recommended. Do not use a pressure washer. The
machine will run cooler and last longer if kept free of
clippings and other debris. A clean machine also re-
duces the risk of re due to accumulation of combus-
tible debris and chaff.
Brush or blow clippings and debris off the machine.
DO NOT use a pressure washer.
WASHING MACHINE
CAUTION: Improperly washing a machine can cause
water to enter bearings and other components. This
can greatly reduce component life.
– DO NOT use a pressure washer. Do not direct
water at bearings or seals. High pressure water
can blow past seals and enter sealed bearings.
– Allow the machine to cool down before washing.
Water on a warm machine can be sucked into
sealed bearings as they cool.
– Avoid getting electrical connections wet. Water
can cause electrical faults and corrosion of elec-
trical components.

ADJUSTMENTS
TRACTION CONTROL LINKAGE
The transaxles on this machine are spring loaded to
the neutral position. The traction control levers need
to be adjusted so the LH lever is in the neutral slot
when the tractions are released. The right hand lever
is adjusted to line up with the left hand lever.
To Adjust:
1. Loosen the jam nuts on either end of the con-
trol rod. Note: the end nearest the ats on the
rod has left hand threads. Adjust the left rod by
turning it to locate the left hand traction lever as
desired.
2. Tighten the jam nuts against the rod ends to lock
the adjustment.
3. Complete the adjustment by turning the right rod
to line up the right traction lever with the left one.
Moving the location of the traction lever in the slot by
way of adjustment can be used to affect top forward
speed and reverse speed of the unit within the limits
of the transaxles control stroke. Adjusting the LH
control to the rear of the neutral slot will increase
forward speed by reducing the available stroke for
reverse and lowering maximum reverse speed. Do
not adjust beyond the point where the end of the hy-
drostat stroke is reached before the control lever hits
the front reference bar with the reference bar moved
all the way forward.
TIRE SCRAPERS
Rear tire scrapers P are provided to prevent mud
build up on the drive tires during operation in muddy
conditions. The tire scrapers should be positioned
so there is about 1/8" (3mm) clearance between the
wheel and the scraper.
To Adjust:
1. Loosen the bolts securing the tire scrapers.
2. Position the tire scraper 1/8" (3mm) from the
nearest tire surface.
3. Tighten bolts.

SA-30 ADJUSTMENTS
MAIN DRIVE CHAIN ADJUSTMENT
The main drive chain has an automatic tensioning
system that normally does not require adjustment.
As the chain wears, the tensioner advances and
locks the idler in the new position. If the automatic
tension has advanced all the way, it may be reset.
1. Raise the machine and support it on the built in
jack stands. Turn off the engine.
2. Remove the front and side chain covers. Push
down on the spring end of the tensioner to
disengage the locking teeth. Pull the tensioner
forward and lock it in place by setting the bolt in
the locking notch.
3. Rotate the tire to get all the slack out of the top
span of the chain.
4. Loosen the idler bolts and move the idler in the
adjusting slot to remove the slack in the chain.
Tighten the idler bolts.
5. Move the tensioner off the locking notch to
engage the locking teeth.
6. Reinstall the chain covers. Start the engine and
lower the machine. Stop the engine and pin the
jack stands in the operating position.
CHAINS
Tines may drop suddenly. Support the tines when
working underneath them. NOTE: It is normal for
there to be some play in the chain.
WHEEL AND TINE DRIVE CHAIN ADJUSTMENTS
1. Raise the machine and support it on the built in
jack stands. See jack stands section page 19.
Turn off the engine. This will allow one of the
sprockets to turn freely so the idler can take up
the slack.
2. Remove the side chain covers.
3. Tension by loosening the idler bolts and sliding
the idler in the adjusting slot to remove slack
from the drive. Tighten the idler bolts. Replace
chain covers.
NOTE: If there is no more adjustment, the chain
needs to be replaced. See Belt / Chain Replace-
ment Section
4. Start the engine and lower the machine. Stop
the engine and pin the jack stands in the operat-
ing position.

BELT REPLACEMENT
NOTE: Use replacement belts from Schiller Grounds
care, Inc. not general purpose belts. Schiller
Grounds Care, Inc. belts are specically designed
for the loads of this machine and will normally pro-
vide longer service life.
ENGINE-TRANSAXLE BELT
1. Remove the front cover. (The two knobs which
secure it are located on the underside of the
machine.)
2. Rotate the engine-transaxle idler arm in a coun-
ter-clockwise direction with a 3/8" ratchet handle
to allow removal of the belt. Remove the belt
from the idler pulley and then from the remaining
pulleys.
3. Loop a new belt around the transaxle and engine
pulleys. Rotate the idler arm in a counter-
clockwise direction to enable the new belt to be
installed in the idler pulley.
4. Reinstall the engine-transaxle belt.
5. Reinstall the front cover.
ENGINE-HYDRAULIC PUMP BELT
1. Remove the front cover. (The two knobs which
secure it are located on the underside of the
machine.)
2. Remove the engine-transaxle belt.
3. Rotate the engine -hydraulic pump idler in a
clockwise direction to allow removal of the belt.
4. Loop a new belt around the pump and engine
pulleys. Rotate the engine-hydraulic pump idler
in a clockwise direction to enable the new belt to
be installed in the idler pulley.
5. Reinstall the engine-transaxle belt.
6. Reinstall the front cover.

SA-30 CHAIN REPLACEMENT
NOTE: It is recommended replacement chains
from Schiller Grounds care, Inc. be used. Schiller
Grounds Care, Inc. supplies a premium quality chain
cut to the correct length. Replace all chains together
for best results under normal circumstances.
Tension on new chains will need to be adjusted after
the rst several hours of operation after the chains
run in. See Chain Adjustment Section.
MAIN DRIVE CHAIN
1. Start the engine and raise the machine on the
jack stands. See jack stands section page 19.
Stop the engine. Open the transaxle by pass
valves so you can rotate the tines and axles
manually.
2. Remove the front, side and tine chain covers.
3. Push down on the spring end of the tensioner to
disengage the locking teeth. Pull the tensioner
forward and lock it in place by setting the bolt in
the locking notch.
NOTE: If replacing all chains, leave main chain
broken and lying in place while the wheel and tine
chains are replaced. It is easier to replace those
chains with the main chain broken because the
wheel and tine sprockets turn freely with the main
chain disconnected.
4. Break the chain by removing the connector link.
Inspect the sprockets. If any sprockets are worn,
remove the chain and replace sprockets before
installing the new chain. If the sprockets are still
in good condition, connect the new chain to the
old chain and use the old chain to pull the new
chain around the sprockets. Remove the old
chain and connect the ends of the new chain
with a new connector link. NOTE: Install all con-
nector links so the closed end is in the direction
of forward travel.
5. Push the idler up to take all the slack out of the
new chain and tighten the idler bolt. Make sure
the slack is out of the top span of the chain.
Move the tensioner off the locking notch to en-
gage the locking teeth.
6. Reinstall the chain covers. Start the engine and
lower the machine. Stop the engine and pin the
jack stands in the operating position.
TINE CHAIN
Tines may drop suddenly. Support tines when work-
ing underneath them.
1. Start the engine and raise the machine on
the jack stands. Stop the engine. Open the
transaxle by pass valves so you can rotate the
tines and axles manually.
2. Remove the front, side and tine chain covers.
3. Break the main chain and leave it lying on the
machine. Figure 1
4. Loosen the idler mounting bolt and back off the
idler.
5. Break the chain by removing the connector link.
Inspect the sprockets. If any sprockets are worn,
remove the chain and replace sprockets. If the
sprockets are still in good condition, connect
the new chain to the old chain and use the old
chain to pull the new chain around the sprockets.
Remove the old chain and connect the ends of
the new chain with a new connector link. NOTE:
Install all connector links so the closed end is in
the direction of forward travel.
6. Take the slack out of the chain by moving the
idler in the adjusting slots. Tighten the idler
mounting bolt. Reinstall main chain.
7. Reinstall the chain covers. Start the engine and
lower the machine. Stop the engine and pin the
jack stands in the operating position.
