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.

using two screws. See Figure 5. Tighten securely.  
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

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.  
NOTE: DECK BRACKET HAS

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  
Figure 8.
