r Do not use this equipment for uses that the mower was not made for.

en-11
SAFETY 3
3.1.4 ROPS
a The ROPS is a safety device. Keep the ROPS in the vertical and locked position. Always use the seat belt
when you operate the mower. Make sure the seat belt can be released quickly in an emergency.
b The ROPS should only be folded if absolutely necessary for storage or when working on flat ground under
low obstructions. Do not operate the mower with the ROPS in the folded position on slopes, near sharp
edges or near water. There is no roll over protections with the ROPS in the folded position
c Do not operate the mower with the ROPS in the folded position on slopes, near sharp edges or near water.
There is no roll over protections with the ROPS in the folded position.
d Check for clearance before you drive below objects. Do not contact tree branches, electrical wires or other
objects with the ROPS.
e Do not use the seat belt with the ROPS in the folded position.
f Inspect the ROPS for damage. Keep the ROPS hardware fastened.
g Do not weld, drill, change or bend the ROPS. Replace a damaged ROPS. Do not try to correct a damaged
ROPS.
h
i
Do not remove the ROPS from the mower. Jacobsen must
approve any changes to the ROPS.
3.1.5 Safe handling of fuels
a The fuel and the fuel vapors are flammable. Use caution when you add the fuel to the mower. The fuel
vapors can cause an explosion.
b Never use the containers that are not approved to keep or transfer fuel.
c Never keep the mower or fuel containers near an open flame or any device that can cause the ignition of
fuel or fuel vapors.
d Never fill the fuel containers inside a vehicle or on a truck or trailer with a plastic liner. Always put the fuel
container on the ground away from your vehicle before you fill the container.
e Refuel the mower before you start the engine. When the engine is in operation or while the engine is hot,
never remove the fuel cap or add fuel to the mower.
f Refuel outdoors only and do not smoke when you add fuel. Extinguish all types of ignition.
g The fuel nozzle must touch the rim of the fuel tank when you add fuel to the mower. Do not use a device to
lock the fuel nozzle in the open position.
h Do not over fill the fuel tank. Leave at least 1 inch (25 mm) below the filler neck.
i Always tighten the fuel tank cap and container cap after you add fuel.
j If the fuel spills on your clothing, change your clothing immediately.
3.1.6 Maintenance and storage
a Before you clean, adjust or repair this equipment, push PTO switch to the OFF position, lower the cutting
unit to the ground, engage the parking brake, stop the engine and remove the key.
b Make sure the mower is parked on a solid and level surface.
c Never work on a mower that is lifted only by the jack. Always use the jack stands.
d Never allow persons to service the mower or its attachments without correct instructions.
e When the mower is parked, put into storage or left without an operator, lower the cutting device unless a
positive lock is used.
f Disconnect the battery before you service the mower. Always disconnect the negative battery cable before

en-12
3 SAFETY
g Charge the battery in an area with good airflow. The battery can release hydrogen gas that is explosive. To
prevent an explosion, keep any device that can cause sparks or flames away from the battery.
h Disconnect the battery charger from the power supply before you connect or disconnect the battery charger
to the battery. Wear protective clothing and use insulated tools when you service the battery.
i Be careful and wear gloves when you check or service the cutting unit blades. Replace any damaged
blades, do not try to correct a damaged blade.
j Keep your hands and feet away from parts that move. Do not adjust the mower with the engine in
operation, unless the adjustment needs the engine in operation.
k Carefully release the pressure from components with stored energy.
l To prevent injury from the hot, high pressure oil, never use your hands to check for oil leaks. Use the paper
or cardboard to find leaks.
m The hydraulic fluid pressure can have enough force to enter your skin. If hydraulic fluid has entered your
skin, a doctor must remove the hydraulic fluid surgically within a few hours or gangrene can occur.
n When you service the hydraulic system, make sure the hydraulic fittings, tubes and hoses are tightened to
the correct torque. Make sure the hydraulic system is in good condition before you start the engine.
o Keep the mower and the engine clean.
p Allow the engine to become cool before storage and always remove the ignition key.
q Keep all nuts, bolts and screws tight to make sure the equipment is in safe condition.
r
s
t
Replace worn or damaged parts for safety. Replace damaged or worn decals. Only use parts, accessories
and attachments approved by Jacobsen.
To decrease the fire hazard, remove materials that burn from the engine, muffler, battery tray and fuel tank
area.
Disconnect the battery and controller connectors before you weld on this mower.
3.1.7 When you put the mower on a trailer

WARNING
California Proposition 65
Engine exhaust, some of Its constituents, and some vehicle components contain or release chemicals
known to the state of California to cause cancer and birth defects or other reproductive harm.
WARNING
To prevent injury from the hot oil at high pressure, do not use your hands to check for oil leaks.
Make sure that you use paper or cardboard.
Release of hydraulic fluid at high pressure has enough force to enter through the skin.
If the fluid enters through the skin, the fluid MUST be surgically removed within hours by a specialist
doctor or gangrene may result.
WARNING
When the machine is driven off-road, a seat belt MUST be worn only when a ROPS Frame is in position.
This warning is because a seat belt must be worn with a ROPS to follow the machinery directive,
2006/42/EC sections 3.2.2, seating & 3.4.3, rollover. (ANSI B71.4-2012 section 20.7)
Jacobsen Limited recommends that the owner/user of the machine completes a local risk assessment
of the machine to find any conditions that do not follow this rule, e.g. when you drive the machine next
to water or on the highway.
WARNING
Explosive gases are released by batteries. The battery contains corrosive acid and supply an electrical
current that is high enough to cause burn injuries to the body.
WARNING
You must not use this machine to tow other vehicles.
WARNING
Ear Protection Must Be Worn When You Operate Machines With
An Operator Ear Noise Level Of More Than 85 db(A) Leq.
WARNING
The reversing fan can start unexpectedly whilst the engine is running, always make sure that the
correct PPE is worn whilst cleaning or during routine maintenance of this vehicle.
Keep hands and loose-fitting garments away from the reversing fan at all times.

SAFETY 3
WARNING
Vibration Exposure Limits
Exposure limits are calculated as a combination of the vibration level (magnitude) of the tool and the
Daily Exposure Time (Trigger Time), e.g. A product with 5m/s² vibration can be used up to 2 hours/day to
reach the EAV and up to 8 hours/day to reach the ELV.
Exposure Action Value (EAV) - Daily vibration exposure A(8) = 2.5m/s²
Where daily vibration exposure A(8) is below 2.5m/s² the risk is relatively low and no action need be
taken
Exposure Limit Value (ELV) - Daily Vibration Exposure A(8) = 5.0m/s²
If several tools are use the exposure values must be combined:
Total exposure is then the combined value of the activities
WARNING
Never mow if there is a risk of lightning or you hear thunder. If you are in the middle of mowing,
stop In a safe place, turn off the engine and go inside a building.
CAUTION
When you do any welding on the machine, the battery, controller and display MUST be disconnected
before you start.
You must not open the controller. If the controller is opened, this can cancel all of the warranties and
can cause the failure of the machine.
CAUTION
Personal protective equipment (PPE), for example safety glasses, leather work shoes or boots, a hard
hat, leather work gloves and ear protection MUST be used after the owner/user completes a local risk
assessment of the mower, to prevent injury.
Training in all manual operations must be given by an approved person before the machine is used the
first time.
