RT800E OPERATOR MANUAL
OPERATING CONTROLS AND PROCEDURES
Backup Alarm (Not Shown)
Hydraulic Reservoir and Filter
The Backup Alarm is an audio system used to warn personnel outside the crane when the crane is backing up. The alarm system is electrical and consists of the backup alarm and its associated wiring. The alarm is connected to the electrical wiring for the transmission reverse solenoids. It is activated when the transmission shifter is in the reverse position. The backup alarm is installed in the rear outrigger box behind the grill plate.
Check hydraulic fluid quantity level and filter condition indicator. Check breather for cleanliness and ensure it is secure.
Emergency Exit The windshield is considered the Emergency Exit. In an emergency, push out on the windshield and escape through the opening.
Tires Check for severe cuts, foreign objects embedded in treads, and for correct inflation pressures. A tire inflation chart, providing the correct air pressures, is located in the Load Chart Book in the crane cab.
Wire Rope Inspect wire rope in accordance with applicable Federal Regulations. Inspect sheaves, guards, guides, drums, flanges, and any other surfaces that may come in contact with the rope for any condition that could cause possible damage to the rope.
OPERATING PROCEDURES Pre-Starting Checks A complete walk-around visual inspection of the crane should always be made with special attention to structural damage, loose equipment, leaks, or other conditions that would require immediate correction for safety of operation. The following checklist items are suggested specifically for the operator’s benefit to make certain his crane is prepared for starting the day’s work.
Fuel Supply
Hook Block Visually inspect for nicks, gouges, cracks, and evidence of any other damage. Replace any hook that contains cracks or shows evidence of excessive deformation of the hook opening, including twist. Be sure the safety latch is free and aligned.
Air Cleaner
Check the fuel level and make sure the cap is on tight.
Check the filter restriction indicator. Check filter and tubing for security.
Engine Oil
Cold Weather Operation
Check the oil level in the crankcase and fill to the FULL mark on the dipstick. Do not overfill.
The following recommendations are for operating Grove cranes in regions with ambient temperatures below -9°C (15°F) which are considered arctic.
Engine Coolant Check the coolant level in the radiator sight gauge and fill to the proper level. Do not overfill and check to make sure the radiator and reservoir caps are secure.
Batteries Check that the battery cables and clamps are tight and not corroded.
Signal and Running Lights Check all signal and running lights for proper operation. Replace burned out lamps with those of the same number or equivalent.
Foot and Parking Brakes Check the foot and parking brakes for proper operation.
Daily Lubrication Make certain that all components requiring daily lubrication have been serviced. (Refer to Section 5, Lubrication.)

NOTE:
Additional information regarding cold weather operation is available through your Cummins dealer/service center under Service Bulletin 3379009.
Use particular care to ensure that cranes being operated in very cold temperatures are operated and maintained in accordance with the procedures as provided by Manitowoc. Therefore, always ensure adequate lubrication during system warm-up and proper operation of all crane functions when operating in cold weather and regardless of the oil viscosity of the crane’s lubricants, always follow the cold weather start-up and operating procedures described in the Operator Manual. To ensure adequate lubrication during system warm-up and proper operation of all crane functions, (Refer to Lubricants and Lubrication Intervals, page 5-1.) If in doubt of the suitability of a specific fluid or lubricant, check with an authorized Manitowoc distributor or Manitowoc Crane Care. Cranes should have appropriate hydraulic oil, lubricants, and other auxiliary items required for operation in sub-zero temperatures.
