TMS800E OPERATOR’S MANUALOPERATING CONTROLS AND PROCEDURES

3. To engage deep low reverse, put the range control switch in the down (low) position. Move the deep reduction switch to the forward (IN) position.

4. Carefully release the clutch, making sure deep reverse is fully engaged.

Driving Tips

• For a smooth start, always select an initial starting gear that will provide sufficient reduction fo r the load and terrain.

• On later model cranes, progressively shift the road control ratios.

• Always use normal double clutching procedures when making lever shifts.

• Never slam or jerk the shift lever to complete gear engagement.

• Never coast with the gear shift lever in the neutral position.

• Never move the deep reduction switch or the range control switch with the gear shift lever in the neutral position while the vehicle is moving.

• Never make a range shift while operating in reverse.

• Never downshift at too high of a road speed.

• When slowing down, the proficient operator can downshift through all the individual gear speeds to prolong the life of the brakes.

• In most cases, depending on the engine and axle ratios, fuel can be saved by operating the crane at less than governed rpm while in 8th gear.

Rear Tandem Inter-Axle/Cross-Axle Locks

Caution

Do not operate differential locks on dry roads.

To engage the inter-axle or cross axle differential locks for maximum pulling power when approaching slippery or poor road conditions, do the following:

Caution

Do not engage or disengage differential locks while wheels are spinning or at speeds over approximately 16 km/h (10 mph).

1. Stop the crane and position the switch to the lock position.

2. Proceed over the poor road conditions cautiously.

When adverse conditions have passed, do the following:

1. Stop the crane and position the switch to the unlock position.

2. Resume driving at a safe speed.

Service/Parking Brakes

For the most effective braking and maximum life from the brake system components, the following suggestions are made.

• Air brakes have light pedal operation and the driver is cautioned to use extreme care in application until a good feel is achieved.

• Use the engine as a brake when approaching a stop or going down a long grade. On a downgrade, use the same transmission gear as would be needed to go up the same grade.

• When necessary to use brakes to reduce crane speed on downgrades, use an on-and-off application to minimize heat and wear. Do not hold a continuous brake application or slide the wheels.

• When driving on slippery pavement or under icy conditions, alternately and smoothly apply and release the brakes to prevent skidding.

• Keep the tires properly inflated. Improperly inflated tires can reduce the efficiency of the brakes.

• After driving through water, dry the brakes by applying them lightly while maintaining a slow forward speed with an assured clear distance ahead until brake performance returns to normal.

Danger

Stop immediately if low air pressure warning sounds and determine cause of air loss, Stop by downshifting and use engine as a brake. Make final stop using a single brake pedal movement to avoid excessive loss of air and sudden engagement of parking brakes.

NOTE: If the pressure drops below 14 kPa (2psi) per minute with the engine stopped, have the air system checked for leaks.

• Regularly check the air pressure gauge. System air pressure should never drop below 310 kPa (45 psi). If both systems drop below 310 kPa (45 psi), the automatic spring brakes will actuate. Normal operating pressure is 725 to 825 kPa (105 to 120 psi).

Danger

Do not use parking brake for stopping crane except in case of an emergency, as a severe sudden stop will occur.

Caution

Release brakes before moving crane, or drive train damage will result.

NOTE: Park brake must be set before outrigger controls can be operated.

• The parking brakes are controlled by a push-pull knob on the front console. Pull the knob out to apply and push the knob in to release the parking brake.

Engine Braking

By energizing the engine brake, the power producing diesel engine, in effect, becomes a power absorbing air compressor. To retard a crane on a downgrade using the engine brake, the operator selects a gear which will provide a balance between engine speed and road speed, then engages the engine brake. If the engine speed exceeds maximum rated rpm for a desired speed, a lower gear can be selected or intermittent use of the service brakes can be made. This selection of a lower gear will generally allow complete control of the crane by the engine brake leaving the service brakes in reserve to be used for emergency stops. With the engine brake turned on, the engine brake will not be energized until the momentum is driving the engine.

1. Position the engine brake On/Off switch to on (push top of switch).

2. Position the engine brake switch to either high (press top of switch) or low (press bottom of switch) position, depending on the amount of braking desired.

3. Let off the throttle to activate the engine braking system and slow the crane.

NOTE: The engine braking system will automatically deactivate when the throttle is depressed.

Caution

Before engaging engine brake on slippery roads, be sure crane is maintaining traction.

Stowing and Parking

Danger

Never park crane near holes, on rocky surfaces, or on soft spots. This may cause crane to overturn, resulting in injury or death to personnel.

When parking the crane, do the following.

1. Remove the load from the hook.

2. Remove or stow boom extensions if so equipped.

3. Fully retract all boom sections.

4. Lower the boom to normal travel position.

5. Engage the swing brake, swing lock pin, and 360 degree swing lock.

6. Retract all stabilizer cylinders and outrigger beams.

7. Turn the crane function power switch to the off position (press bottom of switch).

8. Park the crane on a stable surface.

9. Apply the parking brakes and if necessary, chock wheels.

10. Ensure all operating controls are in neutral position.

11. Shut down engine following proper procedures specified in this handbook and the applicable engine manual.

12. Remove the keys.

13. Close and lock, if applicable, all windows, covers, and doors.

Unattended Crane

Warning

Tipping Hazard!

Changing weather conditions including but not limited to: wind, ice accumulation, precipitation, flooding, lightning, etc. should be considered when determining the location and configuration of a crane when it is to be left unattended.

Failure to comply with these instructions may cause death or serious injury.

The configuration in which the crane should be left while unattended shall be determined by a qualified, designated individual familiar with the job site, configuration, conditions, and limitations.
