SECTION 1
General Sa ety Practices
1.1 HAZARD CLASSIFICATION SYSTEM
1.1.1 Sa ety Alert System and Sa ety Signal Words
DANGER
DANGER indicates an imminently ha ardous situation which, if not avoided, will
result in death or serious injury.
WARNING
WARNING indicates a potentially ha ardous situation which, if not avoided, could
result in death or serious injury.
CAUTION
CAUTION indicates a potentiality ha ardous situation which, if not avoided, may
result in minor or moderate injury.
1.2 GENERAL PRECAUTIONS
WARNING
Before operation, read and understand this manual. Failure to comply with the
safety precautions listed in this manual could result in machine damage, property
damage, personal injury or death.
• Hydraulic cylinders are subject to thermal expansion and contraction. This may result
in changes to the boom and/or attachment position while the machine is stationary.
Factors affecting thermal movement can include the length of time machine is
stationary, hydraulic oil temperature, ambient air temperature and boom and/or
attachment position.
• Precautions to avoid all ha ards in the work area must be taken by the user before
and during operation of the machine.

1.3 OPERATION SAFETY
Note: The manufacturer has no direct control over machine application and operation.
Therefore, safety issues listed in this manual are non-exhaustive. The user and
operator are responsible for conforming with good safety practices.
1.3.1 Electrical Hazards
• This machine is not insulated and does not provide protection from contact or being
near electrical current.
• Always check for power lines before raising the boom.
• Maintain distance from electrical lines, apparatus, or any energi ed (exposed or
insulated) parts according to the Minimum Approach Distance (MAD).
Voltage Range (Phase to Phase) Minimum Approach Distance (MAD)
0 to 50 KV 10 ft (3 m)
Over 50KV to 200 KV 15 ft (5 m)
Over 200 KV to 350 KV 20 ft (6 m)
Over 350 KV to 500 KV 25 ft (8 m)
Over 500 KV to 750 KV 35 ft (11 m)
Over 750 KV to 1000 KV 45 ft (14 m)
Note: This requirement shall apply except where employer, local or governmental reg-
ulations are more stringent.
• Allow for machine movement and electrical line swaying.
• Maintain a clearance of at least 10 ft (3m) between any part of the machine and its
occupants, their tools and their equipment from any electrical line or apparatus
carrying up to 50,000 volts. One foot additional clearance is required for every
additional 30,000 volts or less.
General Sa ety Practices
14 31211849 6036, 6042, 8042, 10042, 10054, 12054

• The minimum approach distance may be reduced if insulating barriers are installed
to prevent contact, and the barriers are rated for the voltage of the line being
guarded. These barriers shall not be part of (or attached to) the machine. The
minimum approach distance shall be reduced to a distance within the designed
working dimensions of the insulating barrier. This determination shall be made by a
qualified person in accordance with the employer, local, or governmental
requirements for work practices near energi ed equipment.
DANGER
Do not maneuver machine or personnel inside prohibited one (MAD). Assume all
electrical parts and wiring are energi ed unless known otherwise.
1.3.2 Tip Over Hazard
General
• For additional load requirements, refer to the appropriate capacity chart.
• Never use an attachment without the appropriate original equipment manufacturer
(OEM) approved capacity chart installed on the telehandler.
• Understand how to properly use the capacity charts located in cab.
•DO NOT exceed rated lift capacity.
• Be sure that the ground conditions are able to support the machine.
• Be aware of wind conditions. Wind may cause load swing and dangerous side loads.
• Keep the machine a minimum of 2 ft (0,6 m) from holes, drop-offs, obstructions,
debris, concealed holes and other potential ha ards at ground level.
•DO NOT raise boom unless frame is level (0 degrees), unless otherwise noted on
capacity chart.
General Sa ety Practices
6036, 6042, 8042, 10042, 10054, 12054 31211849 15

•DO NOT level machine with boom/attachment above 4 ft (1,2 m). (AUS - DO NOT
level machine with load more than 11.8 in (300 mm) above ground surface.)
•MAINTAIN proper tire pressure at all times. If proper tire pressures are not
maintained, this machine could tip over.
• Refer to manufacturer’s specifications for proper fill ratio and pressure requirements
for tires equipped with ballast.
• Always wear seat belt.
• Keep head, arms, hands, legs and all other body parts inside operator’s cab at all
times.
If telehandler starts to tip over:
•DO NOT JUMP
• BRACE YOURSELF and STAY WITH THE MACHINE
• KEEP YOUR SEAT BELT FASTENED
• HOLD ON FIRMLY
• LEAN AWAY FROM THE POINT OF IMPACT
General Sa ety Practices
16 31211849 6036, 6042, 8042, 10042, 10054, 12054

Non-Suspended Load
•DO NOT drive with boom raised.
Suspended Load
• Tether suspended loads to restrict movement.
• Weight of all rigging (slings, etc.) must be included as part of load.
•DO NOT attempt to use telehandler frame-leveling to compensate for load swing.
• Keep heavy part of load closest to attachment.
• Never drag the load; lift vertically.
When driving with a suspended load:
• Start, travel, turn and stop slowly to prevent load from swinging.
•DO NOT extend boom.
•DO NOT raise the load more than 300 mm (11.8 in) above ground surface or the
boom more than 45°.
•DO NOT exceed walking speed.
General Sa ety Practices
6036, 6042, 8042, 10042, 10054, 12054 31211849 17

1.3.3 Travel Hazard
2-Wheel Front Steer 4-Wheel Circle Steer 4-Wheel Crab Steer
• Steering characteristics differ between steer modes. Identify the steer mode settings
of the telehandler being operated.
•DO NOT change steer modes while traveling. Steer modes must be changed while
telehandler is stationary.
• Visually verify proper wheel alignment after each steer mode change.
• Ensure that adequate clearance is provided for both rear tail swing and front fork
swing.
• Look out for and avoid other personnel, machinery and vehicles in the area. Use a
spotter if you DO NOT have a clear view.
• Before moving be sure of a clear path and sound horn.
• When driving, retract boom and keep boom/attachment as low as possible while
maintaining visibility of mirrors and maximum visibility of path of travel.
• Always look in the direction of travel.
• Always check boom clearances carefully before driving underneath overhead
obstructions. Position attachment/load to clear obstacles.
• When driving in high speed, use only front wheel steer (if steering modes are
selectable).
• Telehandlers equipped with solid or foam filled tires should not be used in
applications requiring excessive roading or driving extended distances. In the event
an application requires excessive roading or driving expanded distances, it is
recommended to use telehandlers not equipped with solid or foam filled tires.
General Sa ety Practices
18 31211849 6036, 6042, 8042, 10042, 10054, 12054

1.3.4 Load Falling Hazard
• Never suspend load from forks or other parts of carriage weldment. Use only
approved lift points.
•DO NOT burn or drill holes in fork(s).
• Forks must be centered under load and spaced apart as far as possible.
1.3.5 Li ting Personnel
• When lifting personnel, USE ONLY an approved personnel work platform, with
proper capacity chart displayed in the cab.
•DO NOT drive machine from cab when personnel are in platform.
1.3.6 Driving Hazards on Slopes
To maintain sufficient traction and braking capabilities, travel on slopes as follows:
• When unloaded, drive with forks pointed downhill.
• When loaded, drive with the forks pointed uphill.
• For additional travel requirements, refer to the appropriate capacity chart.
General Sa ety Practices
6036, 6042, 8042, 10042, 10054, 12054 31211849 19

• To avoid overspeeding the engine and drivetrain when driving down slopes,
downshift to a lower gear and use the service brake as necessary to maintain a slow
speed. DO NOT shi t into neutral and coast downhill.
• Avoid excessively steep slopes or unstable surfaces. To avoid tip over DO NOT drive
across excessively steep slopes under any circumstances.
• Avoid turning on a slope. Never engage “inching” or shift to “Neutral” when going
downhill.
•DO NOT park on a slope.
1.3.7 Pinch Points and Crush Hazards
Stay clear of pinch points and rotating parts on the telehandler.
• Stay clear of moving parts while engine is running.
• Keep clear of steering tires and frame or other objects.
• Keep clear from under boom.
• Keep clear of boom holes.
