TMS800E OPERATOR’S MANUAL
OPERATING CONTROLS AND PROCEDURES
deposits on the valves, pistons and rings; and rapid accumulation of sludge in the engine. NOTE: NOTE:
When prolonged engine idling is necessary, maintain at least 800 rpm. After prolonged idle, you may notice momentary white vapor and an odor. This is normal.
Pump Drive The main No. 1 hydraulic pump is driven by an engine PTO. The two-section No. 2 hydraulic pump is direct engine driven.
Control Lever Operation
Racing The Engine DO NOT race the engine during the warm-up period or operate the engine beyond governed speed (as might occur in downhill operation or downshifting). Engine bearings, pistons, and valves may be damaged if these precautions are not taken.
The control lever operation for crane functions is proportional, i.e., the closer the lever is to neutral (center), the slower the system responds. Return the control lever to neutral to hold the load. Do not feather the hoist control to hold the load. NOTE:
Shutdown Procedure 1.
General Crane Operation
Allow the engine to run at fast idle speed for about five minutes to avoid high internal heat rise and allow for heat dissipation.
2.
Position the ignition switch to off (vertical position).
3.
Drain the fuel filter-water separator.
Exhaust Regeneration The engine utilizes a particulate filter in the exhaust system for the reduction of emissions. Under normal operation, the engine runs hot enough to turn soot into carbon dioxide and the particulates do not clog the filter. If the exhaust is not hot enough, the filter begins to clog and the exhaust filter light illuminates. If possible, the crane can be run on a road duty at normal highway speeds to increase engine temperature and engage the automatic regeneration process. If regeneration does not occur, the exhaust regeneration light will begin to flash. Eventually, if regeneration does not occur, the Engine Warning light will also illuminate and regeneration will have to take place.
Preload Check After the crane has been readied for service, an operational check of all crane functions (with no load applied) should be performed. Preload check is as follows: •
Extend and set the outriggers and level the crane.
•
Raise, lower, and swing the boom right and left at least 45 degrees.
•
Telescope the boom out and back in, ensuring all sections extend and retract properly.
•
Raise and lower the cable a few times at various boom lengths. Make sure there are no kinks and that the cable is spooling on the hoist properly.
CAUTION Run the engine at or near the governed RPM during operation of all crane functions. NOTE:
WARNING During regeneration, exhaust temperatures may reach 800° C (1500° F) which is hot enough to ignite or melt common materials. Do not park the vehicle over combustible materials and keep all materials at least 0.6m (2 ft.) away from the exhaust outlet. Exhaust regeneration is automatic and can occur while parked or driving. Engine speed will increase and possibly reach between 1000 and 1500 rpm. Also, a reduction in power might be noticed.
Always operate the control levers with slow, even pressure.
Carefully read and become familiar with all crane operating instructions before and operating the crane.
Using Your Load Chart NOTE:
One of the most important tools of every Grove Manitowoc crane is the load chart found in the crane operator's cab.
NOTE:
Refer to (Figure 3-4) for terms to know in determining lifting capacities.
The load chart contains the lifting capacities of the crane in all allowable lifting configurations, and must be thoroughly understood by the operator. The load chart is divided into capabilities limited by crane structural strength and stability which is shown by a bold line across the chart. Structural strength limits are above the line and stability limits are below the line.
