SECTION 1 - GENERAL SAFETY PRACTICES
1.1 HAZARD CLASSIFICATION SYSTEM
Safety Alert System and Safety Signal Words
DANGER indicates an imminently hazardous situation which, if not avoided, will
result in death or serious injury.
WARNING indicates a potentially hazardous situation which, if not avoided, could
result in death or serious injury.
CAUTION indicates a potentiality hazardous 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.
DANGER OW0010
WARNING OW0021

Section 1 - General Safety Practices
1-2 31200150
1.3 OPERATION SAFETY
Electrical Hazards
• This machine is not insulated and does not provide protection from contact or
being near electrical current.
•NEVER operate the telehandler in an area where overhead power lines,
overhead or underground cables, or other power sources may exist without
ensuring the appropriate power or utility company de-energizes the lines.
• Always check for power lines before raising the boom.
• Follow employer, local and governmental regulations for clearance from
powerlines.

Tip Over Hazard
General
• For additional load requirements, refer to the appropriate capacity chart.
• Never use an attachment without the appropriate JLG 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.
•DO NOT raise boom unless frame is level (0 degrees), unless otherwise noted on
capacity chart.
•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.)

(1,2 M)

Section 1 - General Safety Practices
1-4 31200150
•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 the seat belt.
• Keep head, arms, hands, legs and all other body parts inside operator’s cab at all
times.
If the telehandler starts to tip over:
•DO NOT JUMP
• BRACE YOURSELF and STAY WITH THE MACHINE
• KEEP YOUR SEAT BELT FASTENED
•HOLDONFIRMLY
• LEAN AWAY FROM THE POINT OF IMPACT
OH2291
OH20911
OH2221

Section 1 - General Safety Practices
1-531200150
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.
• Beware of wind. Wind can cause a suspended load to swing and cause
dangerous side loads - even with tag lines.
•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 11.8 in (300 mm) above ground surface or
the boom more than 45°.
•DO NOT exceed walking speed.
OW0060
OW0150

Section 1 - General Safety Practices
1-6 31200150
Travel Hazard
• 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).

Load Falling Hazard
• Never suspend load from forks or other parts of carriage.
•DO NOT burn or drill holes in fork(s).
• Forks must be centered under load and spaced apart as far as possible.
OW0130

Section 1 - General Safety Practices
1-8 31200150
Lifting Personnel
• When lifting personnel, USE ONLY a JLG approved personnel work platform,
with proper capacity chart displayed in the cab.
•DO NOT drive machine from cab when personnel are in platform.
OW0170
OW0190

Section 1 - General Safety Practices
1-931200150
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.
• 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 shift 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.
OW0200

Section 1 - General Safety Practices
1-10 31200150
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.
