Service Manuals provide general guidelines for maintenance and service and are intended for use by trained and experienced technicians. Failure to properly maintain equipment or to follow instructions contained in the Service Manual could result in damage to the products, personal injury, property damage or death. When lifting parts or assemblies, make sure all slings, chains, or cables are correctly fastened, and that the load being lifted is balanced. Make sure the crane, cables, and chains have the capacity to support the weight of the load. Do not lift heavy parts by hand, use a lifting mechanism. Wear safety glasses. DISCONNECT THE BATTERY CONNECTOR before doing any maintenance or repair on electric lift trucks. Disconnect the battery ground cable on internal combustion lift trucks. Always use correct blocks to prevent the unit from rolling or falling. See HOW TO PUT THE LIFT TRUCK ON BLOCKS in the Operating Manual or the Periodic Maintenance section. Keep the unit clean and the working area clean and orderly. Use the correct tools for the job. Keep the tools clean and in good condition. Always use YALE APPROVED parts when making repairs. Replacement parts must meet or exceed the specifications of the original equipment manufacturer. Make sure all nuts, bolts, snap rings, and other fastening devices are removed before using force to remove parts. Always fasten a DO NOT OPERATE tag to the controls of the unit when making repairs, or if the unit needs repairs. Be sure to follow the WARNING and CAUTION notes in the instructions. Gasoline, Liquid Petroleum Gas (LPG), Compressed Natural Gas (CNG), and Diesel fuel are flammable. Be sure to follow the necessary safety precautions when handling these fuels and when working on these fuel systems. Batteries generate flammable gas when they are being charged. Keep fire and sparks away from the area. Make sure the area is well ventilated. NOTE: The following symbols and words indicate safety information in this manual:

WARNING Indicates a hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury and property damage. On the lift truck, the WARNING symbol and word are on orange background. The CAUTION symbol and word are on yellow background.

Description of Operation

Description of Operation CAB STRUCTURE The cab frame is a welded structure. The overhead guard is an integral part of the cab frame. See Figure 1. In order to maintain maximum overhead protection, changes to the cab frame and integrated overhead guard are not allowed. There are two cab options: an open cab and a closed cab. The closed cab features windows and wipers, doors, a heater, and optional air conditioning. Both cab types feature interior components.

CAB TILT SYSTEM On lift trucks with a cab tilt system, the cab can tilt to the right-hand side, providing service access to the engine compartment and components under the cab. The cab tilt system consists of a cab support frame, cab tilt cylinder, cab tilt hand pump assembly, cab latches, and an optional electrical cab tilt pump. See Figure 2. The cab is attached to the lift truck in the lowered position by the cab support pivots on the right-hand frame channel, the two cab latches on the left-hand frame channel, and the cab tilt cylinder.

A. PULL DIRECTION OF THE TILT LATCH RELEASE 1. 2. 3. 4.

CAB SUPPORT FRAME CAB TILT HAND PUMP CAB LATCH CAB TILT CYLINDER Figure 2. Cab Tilt System

Hydraulic pressure is required to unlock the cab latches and extend the cab tilt cylinder. The cab can be raised by rotating the cab tilt hand pump directional valve clockwise and operating the cab tilt hand pump. See Figure 3. To lower the cab from the raised position, rotate the cab tilt hand pump directional valve counterclockwise and operating the cab tilt hand pump. The cab tilt cylinder retracts to lower the cab. The optional electrical cab tilt pump is push-button operated. See Raising and Lowering Cab, Raise Cab, Figure 8. NOTE: If the optional electrical cab tilt pump is inoperable, the cab can be raised or lowered by using the manually operated cab tilt hand pump. A. LOWER B. RAISE 1. PUMP LEVER CONNECTION 2. PUMP DIRECTIONAL VALVE Figure 3. Cab Tilt Hand Pump

Description of Operation When the cab has been raised to the partially open position, the safety latch will engage with a retainer plate that is welded to the frame. To raise or lower the cab after the safety latch has engaged, pull and hold the tilt latch release and raise or lower the cab until the safety latch has passed the retainer plate. Just before the fully open position is reached, movement becomes gravity-controlled by the weight of the cab. The cab is in the fully open position when the cab tilt cylinder is fully extended.

Cab Tilt System, Raise When the directional valve is in the raise position, the pump push port and pump pull port are connected to each other. See Figure 4. Hydraulic pressure is transferred to the cab latches and both the piston and rod side of the cab tilt cylinder. Hydraulic oil extruded at the rod side enters the piston side of the cylinder through the directional valve in the hand pump. The end of stroke is determined by a retaining ring in the cab tilt cylinder.

0100 YRM 1390

Cab Tilt System, Lower When the directional valve is in the lower position, the pump push port is connected to the pump reservoir through a reservoir check valve. The reservoir check valve retains enough pressure to keep the cab locks open. The pump pull port is connected to the hand pump. While the hand pump provides sufficient pressure, the cylinder check valve will raise to allow the oil at the piston side of the cylinder to return to the reservoir. The cylinder cannot lower when there is insufficient pressure at the pull connection. When the piston has reached the free fall area, the oil at the piston side will escape to the rod side and the cab will drop under the influence of its own weight. When the cab drops, the oil in the cab lock cylinders is pushed out through the reservoir check valve. After the cab has dropped, the cab is locked into position by the cab latches.

Oil Filling for Cab Tilt System

0100 YRM 1390

Oil Filling for Cab Tilt System CAUTION When oil is added to the cab tilt system, place an oil absorbing material around the fill cap before lowering the cab. Excess oil may bleed out of the relief valve, which is located in the fill cap. NOTE: If the oil level is low, the cab will not tilt/raise completely.

4. Remove the fill cap. See Figure 5. 5. Add hydraulic oil through the filler opening until the level is within 30 to 35 mm (1.18 to 1.38 in.) of the top of the reservoir. See Figure 6. For your lift truck, refer to the appropriate Periodic Maintenance YRMfor the correct hydraulic oil specification.

NOTE: If the cab is lowered, perform Step 1. If the cab is raised, go to Step 2. 1. Tilt/Raise raise the cab until it locks in the partially open position. Refer to the section Raising and Lowering Cab. 2. Lower the cab until it locks in the partially open position. Refer to the section Raising and Lowering Cab. 3. Place the pump lever connection in the fully down position to create easy access to the fill cap. See Figure 5.

Figure 6. Cab Tilt Label 6. Install the fill cap. See Figure 5. 7. Tilt/raise the cab and make sure the maximum tilted/raised (fully opened) position can be reached. Refer to the section Raising and Lowering Cab. 8. If necessary, repeat Step 1 through Step 7. 9. Lower the cab until it is in the fully lowered position and completely latched. Refer to the section Raising and Lowering Cab.
