NEVER fill fuel tank when engine is running 
or hot from operation.

NEVER fill or drain fuel tank indoors.

Replace fuel cap securely and clean up 
spilled fuel.
Never fill containers inside a vehicle or on a 
truck or trailer bed with a plastic liner. Always 
place containers on the ground away from 
your vehicle before filling.

When practical, remove gas-powered 
equipment from the truck or trailer and refuel 
it on the ground. If this is not possible, then 
refuel such equipment on a trailer with a 
portable container, rather than from a 
gasoline dispenser nozzle.

Keep the nozzle in contact with the rim of the 
fuel tank or container opening at all times until 
fueling is complete. Do not use a nozzle lock-
open device.
If fuel is spilled on clothing, change clothing 
immediately.

NEVER store fuel inside where there is an 
open flame, such as a water heater.

Avoid Electric Shock. Objects contacting both 
battery terminals at the same time may result 
in injury and unit damage. DO NOT reverse 
battery connections.
Reverse connections may result in sparks 
which can cause serious injury. Always 
connect positive (+) lead of charger to 
positive (+) terminal, and negative (-) lead to 
negative (-) terminal.

ALWAYS disconnect negative (-) cable FIRST 
and positive (+) cable SECOND. ALWAYS 
connect positive (+) cable FIRST, and 
negative (-) cable SECOND.

Explosive gases from battery can cause 
death or serious injury. Poisonous battery 
fluid contains sulfuric acid and its contact with 
skin, eyes or clothing can cause severe 
chemical burns.
No flames, No sparks, No smoking near 
battery.

ALWAYS wear safety glasses and protective 
gear near battery. Use insulated tools.

DO NOT TIP battery beyond a 45° angle in 
any direction.
Battery posts, terminals and related 
accessories contain lead and lead 
compounds, chemicals known to the State of 
California to cause cancer and reproductive 
harm. Wash hands after handling.

Reverse connections may cause sparks 
which may result in injury. ALWAYS 
connect/disconnect cables in proper order.

Poisonous battery fluid contains sulfuric acid 
and its contact with skin, eyes, or clothing can 
cause severe burns.

Explosive Gases! No flames, No sparks, No 
smoking near battery.

ALWAYS wear safety glasses and protective 
gear near battery.
ALWAYS keep batteries out of reach of 
children.

Before making any inspections, repairs, etc.: 
disengage PTO, stop unit and engine, set 
parking brake, remove key and allow moving 
parts to stop.

ALWAYS keep body and hands away from 
pin holes or nozzles which eject hydraulic 
fluid under pressure.
Allow hot parts to cool.

ALWAYS block wheels, engage parking brake 
and know all jack stands are strong, secure 
and will hold weight of unit during 
maintenance.

An extension spring, when extended, stores 
energy and can be dangerous. Always use 
tools specifically designed for installing or 
removing an extension spring. Always 
compress or extend springs slowly.
ALWAYS maintain unit in safe operating 
condition. Damaged or worn out muffler can 
cause fire or explosion.

Keep hardware, especially blade attachment 
bolts, tight.

Maintain or replace safety and instruction 
labels, as necessary.
For unit storage or extended storage:

NEVER store with fuel in fuel tank, 
inside a building where any ignition 
sources are present.

Allow engine to cool completely.

Use only attachments or accessories 
designed for your unit and that can be used 
safely on your terrain.

Check attachment components frequently for 
wear, damage or deterioration. Replace with 
manufacturer’s recommended parts for 
safety.
To reduce fire hazard and overheating, keep 
equipment free of grass, leaves, debris or 
excessive lubricants.

Use extra care with grass catchers and other 
attachments. These can change the stability 
of the unit. Use only approved hitch points.

ALWAYS be aware of attachments when 
turning. ALWAYS allow adequate clearance 
between attachments, personnel, and other 
objects.
