IMPORTANT SAFETY INSTRUCTIONS 

 

PREPARATION 

(Continued From Previous Page) 
7.  Keep people and pets out of mowing area. 

Immediately STOP blades, STOP engine, and 
STOP machine if anyone enters the area. 

8. Check shields, deflectors, switches, blade 

controls and other safety devices frequently for 
proper operation and location.  

9.  Make sure all safety decals are clearly legible. 

Replace if damaged.  

10. Protect yourself when mowing and wear safety 

glasses, long pants and substantial footwear. 

11. Know how to STOP blades and engine quickly 

in preparation for emergencies.  

12. Use extra care when loading or unloading the 

machine into a trailer or truck.  

13. 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.  

 

OPERATION  

1.  Mount and dismount machine from left side.  
2.  Start engine from operator's seat, if possible. 

Make sure blades are OFF and parking brake is 
set.  

3.  DO NOT leave machine with engine running. 

STOP engine, STOP blades, SET brake, and 
Remove key before leaving operators position 
of any reason. 

4. DO NOT operate machine unless properly 

seated with feet on feet rests or pedal(s). 

5.  STOP BLADES and ENGINE and make sure 

blades have stopped before removing grass 
catcher or unclogging mower to prevent loss of 
fingers or hand.  

6.  Blades must be OFF except when cutting grass. 

Set blades in highest position when mowing 
over rough ground.  

7.  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.  

8.  DO NOT operate machine without entire grass 

catcher or guards in place. DO NOT point 
discharge at people, passing cars, windows or 
doors.  

9.  Slow down before turning.  
10. Watch out for traffic when near or crossing 

roadways. 

11. STOP engine immediately after striking an 

obstruction. Inspect machine and repair 
damage before resuming operation.  

12. Operate machine only in daylight or with good 

artificial light.  

13. 

Move joystick (if equipped) SLOWLY to 
maintain control during speed and directional 
changes.  

 

OPERATION  

(Continued From Previous Column) 
14. Exercise CAUTION when pulling loads. Limit 

loads to those you can safely control and attach 
loads to hitch plate as specified with SNAPPER 
attachment instructions. 

15. DO NOT operate engine in enclosed areas. 

Engine exhaust gases contain carbon 
monoxide, a deadly poison.  

 

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.  

2.  Keep engine free of grass, leaves or excess 

grease to reduce fire hazard and engine 
overheating.  

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. 

Check that all cotter pins are in proper position.  

6. Always provide adequate ventilation when 

running engine. Exhaust gases contain carbon 
monoxide, an odorless and deadly poison.  

7.  Disconnect negative (black) cable from battery 

before performing maintenance or service. 
Cranking engine could cause injury.  

8.  DO NOT work under machine without safety 

blocks.  

9.  Service engine and make adjustments only 

when engine is stopped. Remove spark plug 
wire(s) from spark plug(s) and secure wire(s) 
away from spark plug(s).  

10. 

DO NOT change engine governor speed 
settings or overspeed engine.  

11. Lubricate machine at intervals specified in 

manual to prevent controls from binding.  

12. Mower blades are sharp and can cut. Wrap the 

blades or wear heavy leather gloves and use 
CAUTION when handling them.  

13. DO NOT test for spark by grounding spark plug 

next to spark plug hole; spark plug could ignite 
gas exiting engine. 

14. 

Have machine serviced by an authorized 
SNAPPER dealer at least once a year and have 
the dealer install any new safety devices.  

15. Use only genuine SNAPPER replacement parts 

to assure that original standards are 
maintained.
