Safety Practices
1.6 SAFETY INSTRUCTIONS
Following are general safety statements to consider before
performing maintenance procedures on the telehandler.
Additional statements related to specific tasks and
procedures are located throughout this manual and are
listed prior to any work instructi ons to prov ide safety
information before the potential of a hazard occurs.
For all safety messages, carefully read, understand and
follow the instructions before
1.6.1 Personal Hazards
PERSONAL SAFETY GEAR: Wear all the protective
clothing and personal safety gear necessary to perform
the job safely. This might include heavy gloves, safety
glasses or goggles, filter mask or respirator, safety shoes
or a hard hat.
LIFTING: NEVER lift a heavy object without the help of at
least one assistant or a suitable sling and hoist.
1.6.2 Equipment Hazards
LIFTING OF EQUIPMENT: Before using any lifting
equipment (chains, slings, brackets, hooks, etc.), verify
that it is of the proper capacity, in good working order, and
is properly attached.
NEVER stand or otherwise become positioned under a
suspended load or under raised equipment. The load or
equipment could fall or tip.
DO NOT use a hoist, jack or jack stands only to support
equipment. Always support equipment with the proper
capacity blocks or stands properly rated for the load.
HAND TOOLS: Always use the proper tool for the job;
keep tools clean and in good working order, and use
special service tool s onl y as re co mme nde d.
proceeding.
1.6.3 General Hazards
SOLVENTS: Only use approved solvents that are known
to be safe for use.
HOUSEKEEPING: Keep the work area and operator’s
cab clean, and remove all hazards (debris, oil, tools, etc.).
FIRST AID: Im mediately clean, dress and report a ll injuries
(cuts, abrasions, burns, etc.), no matter how minor the
injury may seem. Know the location of a First Aid Kit, and
know how to use it.
CLEANLINESS: Wear eye protection, and clean all
components with a high-pressure or steam cleaner
before attempting service.
When removing hydraulic components, plug hose ends
and connections to prevent excess leakage and
contamination. Place a suitable catch basin beneath the
machine to capture fluid run-off.
It is good practice to avoid pressure-washing electrical/
electronic components. In the event pressure-washing
the machine is needed, ensure the machine is shut down
before pressure-washing. Should pressure-washing be
utilized to wash areas containing electrical/electronic
components, it is recommended a maximum pressure of
52 bar (750 psi) at a minimum distance of 30,5 cm (12 in)
away from these components. If electrical/electronic
components are sprayed, spraying must not be direct and
for brief time periods to avoid heavy saturation.
Check and obey all Federal, State and/or Local
regulations regarding waste storage, disposal and
recycling.

Safety Practices
1.6.4 Operational Hazards
ENGINE: Stop the engine before performing any service
unless specificall y instr uc ted othe rw is e.
VENTILATION: Avoid prolonged engine operation in
enclosed areas without adequate ventilation.
SOFT SURFACES AND SLOPES: NEVER work on a
machine that is parked on a soft surface or slope. The
machine must b e on a hard leve l surfa ce, wit h th e wh eel s
blocked before performing any service.
FLUID TEMPERATURE: NEVER work on a machine
when the engine, cooling or hydraulic systems are hot.
Hot components and fluids can cause severe burns.
Allow systems to cool before proceeding.
FLUID PRESSURE: Before loosenin g any hydr aul ic or
diesel fuel component, hose or tube, turn the engine
OFF. Wear heavy, protective gloves and eye protection.
NEVER check for leaks using any part of your body; use
a piece of cardboard or wood instead. If injured, seek
medical attention immediately. Diesel fluid leaking under
pressure can explode. Hydraulic oil and diesel fuel
leaking under pressure can penetrate the skin, cause
infection, gangrene and other serious personal injury.
Relieve all pressure before disconnecting any
component, part, line or hose. Slowly loosen parts and
allow release of residual pressure before removing any
part or component. Before starting the engine or applying
pressure, use components, parts, hoses and pipes that
are in good condition, connected properly and are
tightened to the proper torque. Capture fluid in an
appropriate container and dispose of in accordance with
prevailing environmental regulations.
RADIATOR CAP: The cooling system is under pressure,
and escaping coolant can cause severe burns and eye
injury. To prevent personal injury, NEVER remove the
radiator cap while the cooling system is hot. Wear safety
glasses. Turn the radiator cap to the first stop and allow
pressure to escape before removing the cap completely.
Failure to follow the safety practices could result in death
or serious injury.
FLUID FLAMABILTITY: DO NOT service the fuel or
hydraulic systems near an open flame, sparks or smoking
materials.
NEVER drain or store fluids in an open container. Engine
fuel and hydraulic oil are flammable and can cause a fire
and/or explosion.
DO NOT mix gasoline or alcohol with diesel fuel. The
mixture can cause an explosion.
PRESSURE TESTING: When conducting any test, only
use test equipment that is correctly calibrated and in good
condition. Use the correct equipment in the pr ope r
manner, and make changes or repairs as indicated by the
test procedure to achieve the desired result.
LEAVING MACHINE: Lower the forks or attachment to
the ground before leaving the machine.
TIRES: Always keep tires inflated to the proper pressure
to help prevent tipover. DO NOT over-inflate tires.
NEVER use mismatched tire types, sizes or ply ratings.
Always use matched sets according to machine
specifications.
MAJOR COMPONENTS: Never alter, remove, or
substitute any items such as counterweights, tires,
batteries or other items that may reduce or affect the
overall weight or stability of the machine.
BATTERY: DO NOT charge a frozen battery. Charging a
frozen battery may cause it to explode. Allow the battery
to thaw before jump-starting or connecting a battery
charger.
1.7 S AFETY DECALS
Check that all safety decals are present and readable on
the machine. Refer to the Operation & Safety Manual
supplied with machine for information.

Flats Method:
1. If equipped, lubricate o-ring with hydraulic oil. Hand
tighten the swivel nut until no lateral movement of
the swivel nut can be detected. Average hand torque
is 4 Nm (3 lb-ft).
2. Mark a dot on one of the swivel nut flats and another
dot in line on the hex of the adapter it’s connecting
to.
3. Use the double wrench method while tightening to
avoid hose twist.
4. After the connection has been properly tightened,
mark a straight line across the connecting parts, not
covering the dots indicating that the con necti on has
been properly tightened.

Note: By definition the “Flats Method“ will contain some
variance. Use the “Flats Method” only when accessibility
with a torque wrench is not possible.
Torque Wrench:
1. Identify the appropriate application and refer to the
above chart for the correct torque value.
2. If equipped, lubricate o-ring with hydraulic oil. Hand
tighten the swivel nut until no lateral movement of
the swivel nut can be detected. Average hand torque
is 4 Nm (3 lb-ft).
3. Use the double wrench method while tightening to
avoid hose twist.
4. Torque wrench must be held at the center of the grip.
Apply constant force until it clicks.
5. After the connection has been properly tightened,
mark a straight line across the connecting parts
indicating that the connection has been properly
tightened.
