IMPORTANT SAFETY INSTRUCTIONS
PREPARATION
(Continued From Previous Page)
OPERATION
(Continued From Previous Column)
4. Handle fuel with extra care. Fuels are flammable
and vapors are explosive. Use only an approved
fuel container. DO NOT remove fuel cap or add
fuel with engine running. Add or drain fuel
outdoors only with engine stopped and cool.
Clean spilled fuel from machine. DO NOT
smoke.
5. Practice operation of machine with BLADES
OFF to learn controls and develop skills.
6. Check the area to be mowed and remove all
objects such as toys, wire, rocks, limbs and
other objects that could cause injury if thrown
by blades or interfere with mowing.
6. STOP MACHINE on level ground, lower deck,
engage parking brake and make sure engine
and blades have stopped before removing
grass catcher or unclogging mower to prevent
injury to hands or feet.
7. Blades must be OFF except when cutting grass.
Set blades in highest position when mowing
over rough ground.
8. Keep hands and feet away from rotating blades
underneath deck. DO NOT place foot on ground
while BLADES are ON or machine is in motion.
9. DO NOT operate machine without entire grass
catcher or guards in place. DO NOT point
discharge at people, passing cars, windows or
doors.
7. Evaluate the terrain to determine what
accessories and attachments are needed to
properly and safely perform the job. Only use
accessories and attachments approved by
SNAPPER.
10. Slow down before turning.
11. Watch out for traffic when near or crossing
roadways.
8. Keep people and pets out of mowing area.
Immediately, STOP blades, STOP engine, and
STOP machine if anyone enters the area.
9. DO NOT operate machine unless all shields,
deflectors, switches, blade controls and other
safety devices are in place and functioning
properly.
12. STOP engine immediately after striking an
object or if an abnormal vibration occurs.
Remove key. Remove and disconnect the
sparkplug wire. Make necessary repairs before
resuming operation.
13. Mow only in daylight or with good artificial light.
14. Move motion control levers SLOWLY to
maintain control during speed and directional
changes.
10. Make sure all safety decals are clearly legible.
Replace if damaged.
11. Protect yourself when mowing and wear
appropriate clothing including safety glasses,
long pants, ear protection, hardhat and
substantial footwear with good traction. Long
hair, loose clothing or jewelry may get tangled
in moving parts.
15. Exercise CAUTION when pulling loads. DO NOT
pull loads greater than 300 pounds. Avoid jack
knifing. DO NOT turn sharply.
16. DO NOT operate engine in enclosed areas.
Engine
exhaust
gases
contain
carbon
monoxide, an odorless and deadly poison.
12. Know how to STOP blades and engine quickly
in preparation for emergencies.
13. Use extra care when loading or unloading the
machine into a trailer or truck.
14. Check grass catcher components frequently for
signs of wear or deterioration and replace as
needed to prevent injury from thrown objects
going through weak or worn spots.
MAINTENANCE
1. DO NOT store machine or fuel container inside
where fumes may reach an open flame, spark or
pilot light such as in a water heater, furnace,
clothes dryer or other gas appliance. Allow engine
to cool before storing machine in an enclosure.
Store fuel container out of the reach of children in
a well ventilated, unoccupied building. Shut off
fuel (when equipped with valve) while storing or
transporting machine.
OPERATION
1. Mount and dismount machine from left side.
2. Start engine from operator's seat. Make sure
blades are OFF and parking brake is set. Use
seat belts if provided.
2. Clean grass and debris from engine, mufflers,
drives and cutting units to help prevent
overheating and fires. Clean up fuel, oil and
excess grease.
3. When draining fuel tank, drain fuel into an
approved container outdoors and away from open
flame.
4. Check brakes frequently; adjust, repair or replace
as needed.
5. Keep all bolts, nuts and screws properly tight.

STEP 8: Place a 2x4 under each rear caster. Block the
front caster wheels so that they will not roll.
1) REMOVE HARDWARE.
2) EXTEND CASTER OUT TO LAST SET OF
HOLES.
3) REINSTALL HARDWARE.
STEP 9: Locate jam nuts on the right timing rod and
the right rear deck hanger rod. See Figures 6 and 12.

STEP 10: Run each (2) jam nut up against the swivels
on the timing rod and the hanger rod. The deck linkage
will not float when the nuts are in this position. This will
allow the use of the electric actuator on the deck to lift
and attach the deck frame to the power unit.
STEP 11: Located on the hitch plates at the front of the
Power Unit, rotate the Spring-Loaded Hitch Latch Pins to
the unlatched position. See Figure 7.

STEP 13: Disengage Parking Brake. Carefully move
Power Unit close to Mower Deck to connect Power Unit
and Deck Wiring Harness. Turn engine “OFF”. Plug in
Deck Lift Wiring Harness from Power Unit into Deck Lift
Wiring Harness. Turn Switch key to “ON” position (Do
Not start engine!). Hold Deck Lift Switch in the “DOWN”
position until the lift arm pins are in line with the hitch
plates. See Figures 7 & 8.
STEP 14: Engage Parking Brake. Start engine and
drive Power Unit forward until Lift Arm Pins are
completely inserted into Hitch Plates. Once Lift Arm is in
position with Hitch Plates, move Deck Lift Switch to the
“UP” position and Lift Arm Pins will move lower into Hitch
Plates. Stop engine. Rotate both Hitch Latch Pins
around until they lock Lift Arm into Hitch Plates. See
