STRUCTURE (ROPS) & FALLING OBJECT PROTECTIVE STRUCTURE (FOPS)
This machine is equipped with a Roll-Over Protective Structure (ROPS) to guard the operator if the machine tips over. The Falling Object Protective Structure (FOPS) is built into the ROPS. The FOPS protects the operator from falling objects.
Despite the protection of the ROPS/FOPS, it cannot protect the operator f rom every possible hazard. Do not consider the ROPS/FOPS a substitute for safe practices and good common sense.
Any modification to a ROPS/FOPS, such as welding or drilling holes in the structural members for mount ing brackets, will affect the ROPS/FOPS capability to provide the required protection.
Any modification or repair without the specific written approval of LULL INTERNATIONAL, INC. will void the ROPS/FOPS certif ic at io n. Contact your authorized LULL INTERNATIONAL, INC. dealer before making any modifications or repairs. Failure to do so may v oid the ROPS/FOPS certification.

BEFORE OPERATING THE MACHINE
PLAN YOUR WORK
Before you operate, know how and where you will travel, turn and pickup, lift and place loads.
Choose a smooth level route to prevent possible tipover or loss of load.
If possible, avoid cro ssi n g…
Ruts.
Ditches.
Curbs.
Exposed railroad tracks.
Note: When these conditions cannot be avoided, keep
the load as low as possible and travel very slowly and with extreme caution.
Know where there are any blind corner conditions on the worksite. Before t urning a blind corner, stop, sound your horn, and proceed slowly.
Always maintain safe dist ances between your forklift and other equipment that may be on the worksit e.
Know the weights of all loads you may be expected to transport before attempting to lift them. Avoid loads of loose material if possible. Check that loads ar e properly banded or strapped together.
If you will be placing l oads at high elevations, remember your depth perception is decreased because of distance. Use a signal person near the point where the load is to be landed.
Insure that adequate clearance is provided between both rear tail swing and front fork swing of the forklift to avoid injury to personnel or damage to nearby equipment.
An operator must not use drugs or alcohol which can affect his alertness and coordination. An operator on prescription or over-the-counter drugs needs medical approval to safely operate these machines.
KNOW THE RULES
Most employers have rul es governing proper operation and maintenance of equipment. Before you start work at a new location, check with your supervisor or the safety coordinator. Ask about rules you may be expected to obey.
Make sure you understand the rules covering traf fic at your jobsite. Make sure you recognize and understand the meaning of all signs, flags, and markings. Make sure you understand all hand, flag, whistl e, siren, or bell signals. Make sure you know when to use lights, turn signals, flashers and horn.
PROTECT YOURSELF
Wear all the protective clothing and personal saf ety devices issued to you or called for by job conditions.
You may need:
A hard hat.
Safety shoes.
Safety glasses, goggles, or face shield.
Heavy gloves.
Hearing protection.
Reflective clothing.
Know where you will be expect ed to park your forklift at the end of the work day, preferably in a level area out of traffic. If the area i s on a slope or incline, posi tion the forklift at right angles to the slope, set the parking brake, lower the boom to the ground, and block the wheels.
Remember…
Be alert - know that conditions can change.
Use common sense - show that you are a responsible operator.
Be a defensive operat or - prevent accidents before they happen.
SAFE MACHINE OPERATION
For safe operation of this rough terrain forklift you must be a qualified and authorized operator. To be qualified, you must understand the written instructions supplied by the manufacturer, have training (including actual operation of this m achine) and know the safety rules and regulations for the jobsite.
20
Wet weather gear.
Respirator or filter mask.

FUEL REQUIREMENTS
General
Diesel fuels are blended to meet the local temperature requirements. The standard grades are:
1. 1D for temperatures -22 to +86 °F (-30 to +30 °C).
2. 2D for temperatures +14 to +122 °F (-10 to +50 °C)
There are two main classifications of diesel fuel in general use:
1. Low-sulphur, “on-highway” diesel fuel.
2. Medium-sulfur, “off -highway” diesel fuel. This fuel contains blue dye.
The engine manufacturer specifies the diesel fuel requirements. Additional information can be found below and in the engine manufacturer’s Operator’s Manual.
Consult your local fuel distributor for the properties of the diesel fuels available in your area.
John Deere Engines
Use of regular-sulfur “off-highway” diesel fuel is recommended.
If low-sulfur “on-highway” diesel fuel is used, John Deere Diesel Fuel Conditioner (TY22030) must be added.
Use of low-sulfur fuel without the specified conditioner may cause premature fai lure of the engine’s f uel system components and void the warranty.
Automatic Trans mission Fluid (A TF) may on ly be used at ambient temperatures below +14 °F (-10 °C)

GENERAL OPERATING PROCEDURES - SUPPLEMENT

DRIVE LOCKOUT OVERRIDE
Important: Read and understand the following
instructions BEFORE using the optional Drive Lockout Override System!
Theory of Normal Operation
This machine is equipped with a stabilization system that does several things to increase lateral (side-to­side) stability.
When the boom is raised above 20° elevation:
The transmission is limited to first and second
gears.
The rear oscillation lock cylinder is limited to slow
(orificed) movement.
The speed of the frame tilt function is limited.
When the boom is raised above 40° elevation:
The rear axle stabilization cylinder is locked,
preventing the frame from rotating on the rear axle.
The transmission is disengaged, stopping drive
capabilities.
These functions help prevent tipover accidents which can cause serious injuries and death. The owner/operator manual describes the normal use and operation of a telescopic handler and tells the operator to carry the load and forks as low as possible, but not above eye level.
The Rear Oscillation Lock System stops the machine from driving when the boom angle is above 40°. Driving with the boom elevated (loaded or empty) can be very dangerous, especially on uneven terrain. The machine’s center of gravity is highest when the boom is elevated, which makes it less stable laterally as the boom is raised higher. Improperly driving the machine introduces dynamics that can add to instability and lead to a tipover.
Diagram 2: Stability Rectangle (Front and rear
axles locked, preventing frame from rotating)
When the boom angle is below 20° the machine operates with a freely oscillating rear axle to negotiate rough terrain. (See Diagram 1)
When the boom angle is above 20°, the rear axle cylinder is orificed, slowing movement of the frame on the rear axle. This increases the lateral (side-to-side) stability.
When the boom angle is above 40°, the rear axle cylinder locks, preventing the frame rotating on the rear axle. This changes the stability diagram from a triangle to a rectangle (when viewed from above) and substantially increases the machine’s lateral stability. (See Diagram 2)
General Description, Drive Lockout Override System
In some special applications, it is not possible to carry or place the required load unless the machine is driven with an elevated boom. The Drive Lockout Override System is designed to allow this and MUST BE USED
WITH EXTREME CARE!
The Drive Lockout Override System does two things when engaged with the boom angle above 40°:
Allows the transmission to be engaged in first gear
only.

frame free to rotate on rear axle)
Supplement P09836 Origin 1/98 1
Unlocks the rear oscillation lock cylinder and
allows very slow (orificed) movement. This increases dynamic lateral stability while the machine is being driven.

GENERAL OPERATING PROCEDURES - SUPPLEMENT
Operation of the Drive Lockout Override System
To operate the Drive Lockout Override System:
WARNING
WARNING
Failure to follow the instructions in this supplement and the owner/operator manual may result in serious personal injury or death!
Note: These procedures only apply to situations where
the boom is above 40° elevation.
1. Plan your route of travel. The surface must be firm and as level as possible. Always avoid rough or steep areas.
2. Level the frame before picking up the load. If load is suspended (slung load), make sure tag lines are secure and manned. Never let a slung load sway, as this may lead to machine tipover or injury to personnel.
3. With the brakes on, move the shift selector to the Forward or Reverse position.
4. Using your left foot, press and hold down the Drive Lockout Override Switch. The drive will engage in first gear only and the machine may be moved.
5. Drive the machine very slowly, while carefully watching the terrain. Make turns smoothly and slowly.
6. Use the service brakes to stop the machine slowly and smoothly. Releasing the Drive Lockout Override Foot Switch will disengage the drive, but this will not activate the brakes.
ALWAYS LEVEL MACHINE BEFORE RAISING BOOM. WHEN DRIVE LOCKOUT OVERRIDE IS USED TO MOVE MACHINE WITH BOOM ELEVATED, FRAME LEVEL CAN CHANGE WITH CHANGING TERRAIN. ADJUST FRAME TILT TO KEEP FRAME AND BOOM AS LEVEL AS POSSIBLE WHILE DRIVING. NEVER EXCEED ± 5° FROM LEVEL. LEVEL FRAME SLOWLY AND CAREFULLY. FAILURE TO FOLLOW THE INSTRUCTIONS IN THIS SUPPLEMENT AND THE OWNER/OPERATOR MANUAL MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH!
