Model 6036
13
Safety Practices
Operational Considerations
1. Preparation and Prevention
Know the location and function of all vehicle controls.
Make sure all persons are away from the vehicle and that the travel select lever is in the (N) NEUTRAL position and the Neutral Lock Lever is in the (N) NEUTRAL LOCK position with the parking brake switch engaged before starting the engine.
Holes, obstructions, debris and other worksite hazards can cause death or serious personal injury. Always walk around and look for these and other hazards before operating the vehicle in a new worksite.
Prevent accidents when you move the vehicle around the worksite. Know the rules for movement of people and vehicles on the worksite. Have a person act as a lookout for you. Follow the instructions of signals and signs.
DO NOT operate the vehicle unless all hazard and instructional decals are in place and readable. (Replace all missing, illegible, or damaged decals.)
2. Clearances
Look out for and avoid other personnel, machinery and vehicles in the area. Use a spotter if you do not have a clear view of conditions that affect clearances. Travel with the boom fully retracted and lowered as far as possible while still maintaining enough ground clearance for conditions.
Always check boom clearances carefully before driving underneath door openings, bridges, etc.
Always check for power lines when raising the boom. Beware of overhead wires. Contact with electrical power lines can result in electrocution. See “Electrocution Hazards” on page 15.
3. Visual Obstruction
Dust, smoke, fog, etc. can decrease vision and cause an accident. Always stop or slow the vehicle until the obstruction clears and the worksite is visible again. Have a lookout person assist you.
Where the load will obstruct the operator’s vision, it is recommended that the vehicle be operated in REVERSE, looking backwards in the direction of travel. Travel at a slower speed and get someone to direct you.
14
Model 6036
Safety Practices
4. Underground Hazards
Know the location of all underground hazards before operating this vehicle in a new area or worksite. Electrical cables, gas and water pipes, sewer, or other underground objects can cause death or serious personal injury. Contact your local underground utility service or diggers hotline to mark all underground hazards.
5. Electrocution Hazards
NEVER operate this vehicle in an area where overhead power lines,
overhead or underground cables, or other power sources may exist without first requesting that the appropriate power or utility company de­energize the lines, or take other suitable precautions.
OS0063
Model 6036

7. Tip Over Hazard
DANGER
VEHICLE TIPOVER can result in death or serious injury.
DO NOT travel with the boom raised.
DO NOT raise boom while on a slope unless load is level.
Traveling with the boom raised is dangerous and can cause tipover. Keep the boom as low as possible. Travel with extreme caution the slowest
possible speed.
Keep the vehicle under control at all times. When negotiating turns, slow down and turn the steering wheel in a smooth sweeping motion. Avoid jerky turns, starts or stops. Reduce vehicle speed on rough ground and slopes.
DO NOT exceed the rated lift capacity of the vehicle as structural damage and unstable conditions will result.
To ensure that the vehicle is positioned in the most stable condition before operating an attachment, use the frame sway control (frame tilt) to level the vehicle. The vehicle is level when the frame level indicator gauge reaches (0°) zero degrees.
MAINTAIN proper tire pressure at all times.
and at
OS0086
If the vehicle cannot be leveled using the frame sway control, reposition the vehicle.
Frame swaying left or right with the boom raised above horizontal is dangerous. Always use the frame sway control to level the vehicle before
raising the boom above horizontal, with or without a load. If the vehicle cannot be leveled using frame sway control, reposition the vehicle.
8. Emergency Exit Rear Window
The rear window (Figure 2, 1) in the enclosed cab can be used as an emergency exit by removing the latch pin (2) located on the window latch (3). The window is then free to swing open.

Safety Practices
11.Slopes
DO NOT park the vehicle on an incline and leave it unattended.
Driving across a slope is dangerous, as unexpected changes in
the slope can cause tipover. Ascend or descend slopes slowly and with caution
Ascend or descend slopes with the heavy end of the vehicle pointing up
NOTE: The rear of the vehicle is normally considered the heavy end unless the carriage is fully loaded. In this case the front of the vehicle is now the heavy end.
Unloaded vehicles should be operated on all slopes with the carriage pointing down
On all slopes, the load must be tilted back and raised only as far as necessary to clear the ground.
When operating on a downhill slope, reduce travel speed and downshift to a low gear to permit compression braking by the engine and aid the application of the service brakes.

the slope.
12.Falling Load Hazard
DO NOT exceed the total rated load capacity of the specific type fork
being used. Each fork is stamped with a maximum load capacity. If the capacity is exceeded, forks may break. See “Fork Ratings” on page 77.
DO NOT downshift at a high ground speed. Sudden slowing can cause the load to drop off the forks.
13.Ventilation
DO NOT operate this vehicle in an area with flammable dust or vapors
unless good ventilation has removed the hazard. Sparks from the electrical system and the engine exhaust can cause an explosion.
Carbon monoxide fumes from the engine exhaust can cause suffocation in an enclosed area. Good ventilation is very important when operating this vehicle.

Seat Belt
(Figure 14)
WARNING: Serious bodily injury or death may result from
failure to wear the seat belt installed on this vehicle. The seat belt is a critical component of the Operator’s Protective Structure, and is provided for the operator’s protection in case of vehicle upset. The seat belt MUST be worn whenever this vehicle is operated.
IMPORTANT! Inspect the seat belt every time it is used, looking for cut or worn webbing, or any defect in the latch assembly. If any wear or damage is noted, DO NOT operate the vehicle until the seat belt is replaced.
Before the engine is started, adjust the seat as required for position and comfort. Then adjust the seat belt as follows:
1. Grasp both free ends of the belt and make certain that the belt web­bing is not twisted or entangled in any portion of the seat assembly.
2. With your back straight in the seat, couple both ends of the belt.
3. With the belt buckle as low on your body as possible, pull the free end of the belt to shorten it until it is tight across the lap.

:
WARNING:
NEVER use starting fluid near an open flame. NEVER use starting fluid in a vehicle equipped with an electrical
preheat option or flame air heating system. DO NOT breathe starting fluid fumes. Death or serious personal injury could result from toxic fumes. DO NOT use excessive amounts of starting fluid when cold start­ing an engine. Death or serious personal injury could result from backfire of flame which could ignite the starting fluid canister and cause an explosion.
IMPORTANT! It is recommended that a second person be present when attempting to cold start the engine without metered starting fluid equipment. One person will sit in the operator’s seat and operate the ignition switch and another “helper” is needed to spray the starting fluid.
IMPORTANT! It is important to know that timing is crucial in cold starting an engine. DO NOT spray ether into the air cleaner intake before the procedure instructs you to.
CAUTION:
DO NOT use excessive amounts of starting fluid. Because it is difficult to describe how much starting fluid should be used, it is important to avoid soaking the air cleaner element. An engine backfire could destroy the internal air cleaner elements and other engine damage may occur. It is much better to spray the fluid intermittently than continual spraying.

Jump Starting
Jump starting at the battery or battery replacement is required when the battery is discharged to the point where the battery will not crank the starter.
WARNING: NEVER jump start the vehicle directly to the
starter solenoid. Death or serious personal injury could result from the vehicle lurching forward or backward and running over the per­son attempting to jump start the vehicle directly to the starter.
WARNING: To avoid death or serious personal injury when
jump starting with another vehicle, be certain that the two vehicles are not touching. Never jump start a frozen battery as it will explode. Keep sparks, flames and lighted smoking materials away from the battery. Lead acid batteries generate explosive gases when charging. Wear safety glasses when working near batteries.
The booster battery must be a 12 volt type. The vehicle used for jump starting must have a negative ground electrical system. To jump start the vehicle, proceed as follows:
1. Connect the positive (+) jumper cable to the positive (+) post of the discharged battery.
2. Connect the other end of the positive (+) jumper cable to the posi­tive (+) post of the booster battery.
3. Connect one end of the negative (-) jumper cable to the negative (-) post of the booster battery.
4. Make the final cable connection to the furthest point from the bat­tery.

Refueling
Make sure the vehicle is level to assure an accurate fuel level reading. The fuel tank is capable of holding 37 gallons (140 liters) of diesel fuel. The usable capacity of the fuel tank is 35.6 gallons (135 liters).
Fuel Types
OH0480
Use ASTM #2 diesel fuel with a minimum Cetane rating of 40. #2 diesel fuel gives the best fuel economy and performance under most operating conditions. Fuels with Cetane ratings higher than 40 may be needed in higher altitudes or extremely low ambient temperatures to prevent misfiring and excessive smoke.
When operating at temperatures above 32° F (0° C), use standard #2 diesel fuel.
When operating at temperatures below 32° F (0° C), use a blend of #1 & #2 diesel fuels, most commonly known as “winterized” #2 diesel.

Four Wheel Steer Indexing
If the vehicle does not drive “straight,” the steering could be ”out of phase.” Perform the “Four Wheel Steer Indexing Procedure” on page 162 to synchronize the front and rear steering.
1. Four Wheel Steering
(Figure 40)
WARNING: NEVER use the Four Wheel Steering Mode
when traveling at high speed. Rapid turning in this mode can cause tipover. Use only the Front Wheel Steering Mode at higher speeds and slow the vehicle when turning.
The front wheels will steer in the direction that the steering wheel is turned; the rear wheels will steer in the opposite direction. This steering mode allows an extremely short turning radius and enables the rear wheels to follow the tracking of the front wheels which can be an advantage in mud and sand conditions.

OH1960
Figure 46
Model 6036
Operation
As the boom is extended, boom extend letters will appear on the left side of the boom visible to the operator. The letters are graduated in four foot increments. These letters indicate the point of boom extension and correspond to the capacity chart. For example, when the letter “A” first appears, the boom is at the point of boom extension corresponding to the arc of line “A” throughout the entire capacity charts (Figure 47) through (Figure 50).
The boom angle indicator, located on the left side of the outer boom, indicates the angle of the boom and also corresponds with the angles indicated on the capacity chart.
To accurately use the capacity chart, the operator must first determine three important things:
1. Weight
2. Height
3. Distance tires.

of the structure where the load is to be placed.
where the load will ultimately be placed in front of the front
WARNING: DO NOT exceed rated capacities. Any attempt
to lift or carry loads in excess of those shown on the capacity chart in the operator's compartment may cause vehicle tipover, loss of load or structural damage which could result in death or serious injury.
Model 6036
71
Operation
Reading The Capacity Chart
Example:
1. The operator has placed the load onto the forks, fully retracted the boom, positioned the vehicle perpendicular to the structure and leveled the vehicle. Refer to the load placement example (Figure 47, 1).
2. The operator then determines that:
The load weight is 6,000 pounds (2.721 kg).
The height of the structure the load is to be placed upon is 28
feet (8,5 meters) from ground level.
The distance where the load will ultimately be placed in front of
the vehicle is 8 feet (2,4 meters) from the front of the front tires.
3. After applying the height of the structure and the distance of load placement away from the vehicle to the capacity chart (Figure 47), the operator knows that it will be safe to place the load if the boom extend letter “B” has appeared and the boom angle indicator reading does not go below approximately 55°. This condition is however, a maximum limit for this weight, height and distance away from the vehicle. The operator should move the vehicle closer to the structure to assure that the vehicle will not exceed the maximum limits for placing the load.

Fork Ratings
All approved forks for this vehicle are marked with a maximum load capacity rating. This rating (Figure 51, 1) is stamped on the left edge of the fork (2) just below the fork pivot shaft (3). The rating is listed in U.S. pounds and based upon a 24" (610 mm) load center. This rating specifies the maximum load capacity that the individual fork can safely carry at a maximum load center (4) of 24" (610 mm).
Since forks are always used in multiples, the total rating of any combination of forks will be the sum of their rated capacity. Other than block forks, all forks should be used in matched pairs. Block forks should be used in matched sets.

Operation
How To Pick, Carry & Place A Load
To pick a load, tilt the carriage forward so the forks hang freely on the fork shaft. Move the forks inward or outward on the fork shaft so that they are aligned with the openings in the pallet. Tilt the carriage back and extend the boom slowly so the forks slide into the openings in the pallet. Raise the boom so that the load is lifted.
To carry a load, position the boom so that the load is as low as possible and the travel area is visible to the operator.
Use the capacity chart to determine safe boom extension range for the applicable load. To place a load, align the forks at the level the load is to be placed and then extend the boom slowly until the load is just above the area where it is to be placed. Lower the boom until the pallet rests in position and the forks are free to retract. Retract the forks slowly
from under the load.
Elevating Personnel
This vehicle is designed to lift and transport materials and should not be used to elevate personnel except as explained in this section. Only equipment designed and approved for elevating personnel should be used.
If the vehicle must be used to elevate personnel, use only an approved work platform. When using a work platform, the following precautions must be taken:
WARNING: Use only an approved work platform to lift or
lower personnel. Never drive the vehicle with the work platform in a raised position or with personnel on board, even for a short dis­tance.
Preparation and Setup
1. Make sure that the work platform is securely attached to the quick attach or forks. Follow the platform manufacturer’s instructions.
2. Make sure the platform, carriage and forks are secured to prevent them from pivoting from side to side.
3. Ensure the vehicle has a firm footing and is level.
4. Place the travel select lever in (N) NEUTRAL and move neutral lock lever to NEUTRAL LOCK position.
78
Model 6036
Operation
5. Engage the parking brake switch. Blocking the wheels is also rec­ommended.
6. Level the platform in both the side-to-side and front-to-back direc­tions before use.
WARNING: Never tilt the platform forward or rearward
when elevating with personnel aboard. Death or serious personal injury could result.
DANGER: Never operate this or any equipment in an area in
which overhead or underground cables or power sources exist without first requesting that the appropriate power company or utility company de-energize the lines or take other suitable pre­cautions.
Elevating Personnel
1. Make sure there are no overhead obstructions or electrical wires above the platform before lifting.
2. A trained operator must operate the controls from the operators compartment and must remain with the vehicle at all times. Using extreme caution, lift and lower personnel smoothly and only at their request. The operator should move the platform up and down only in response to instruction from personnel on the platform.
3. Always position the platform in the travel position (approximately one foot above ground level), without personnel in the platform, before moving the vehicle.
IMPORTANT! Make sure that required restraining equipment such as railings, chains, cable, body belts with lanyards, etc. are in place and properly used. Never use railings, planks, ladders, etc. on the platform for the purpose of achieving additional reach or height.
Capacity Limitations
The combined mass (weight in pounds) of the platform, load and personnel shall not exceed one-third position indicated on the capacity chart. Refer to “Using The Capacity Chart” on page 70.

Part ll - Hydraulic Line Failure
In case of hydraulic line failure, there are step-by-step procedures available to assist you in safely retracting and then lowering the boom. Read Part II from start to finish before performing any of these procedures so you fully understand the process and the danger involved. If you are unsure about any part of these procedures contact your local JLG Authorized Service Center or the JLG Service Department.
Every attempt should be made to repair the hydraulic line failure and to retract and then lower the boom in its normal fashion. We realize this is not always possible. Step-by-step procedures are also available when the boom must be retracted and lowered immediately and replacement parts are not available. Only resort to Steps 3 & 4 when absolutely necessary.
IMPORTANT! Be aware that the boom must first be retracted and then lowered to avoid vehicle tipover.
In any case of hydraulic line failure, it is critical to correctly identify which hydraulic line (Figure 54) has failed. Identify the hydraulic line that has failed: Boom Retract line (1), Boom Extend line (2), Boom Lift line (3) and Boom Lower line (4). Use the table on page 87 to determine which Step to follow to retract and lower the boom.

WARNING: Wear protective clothing and proper eye pro-
tection when working with or around hydraulic oil. Wait for hydrau­lic oil to cool before attempting to repair the failure. Hot hydraulic oil can cause severe burns and other serious injury.
NOTE: If a replacement hose is not available, the adjacent boom lift line (Figure 57) can be used to replace the failed boom lower line.
7. Remove the individual failed boom lower line (Figure 57, 1) from the circuit.
8. Remove and temporarily reposition the adjacent boom lift line (Figure 57, 2) in place of the failed boom lower line (1).
IMPORTANT! Once either boom lift line is removed and the boom is retracted during the remaining steps, hydraulic oil will drain out of the base end of the boom cylinder. The escaping oil should be deflected by some means (the failed hose could be used) directing the oil into the drain container.
