OPERATION To release the parking brake, grasp the brake handle firmly, pull the han- dle up slightly and squeeze the lock lever below the handle. Lower the handle down completely until it is fully released. The brake set indicator will go off indicating the brakes are released. Remark The rear wheel must be firmly on the ground in order for the parking brake to work. Always set the parking brake when exiting the cab. ACCELERATOR PEDAL The accelerator pedal (3) is used mainly for road travel or when using the front end loader. When using the front end loader with the accelera- tor pedal, be careful not to strain the machine. Always accelerate smoothly when loading the front end loader.
HAND THROTTLE The hand throttle is used when operating the backhoe or front end loader. It can also be used during engine warm up or during mainte- nance. The positions for the hand throttle are: Idling Position: Throttle handle pulled forward. Maximum RPM Position : Throttle handled pulled back. Throttle Operating Tips Avoid using the machine with the throttle lever completely in the maxi- mum RPM position. Fuel consumption and engine ware will be increased at high engine speeds. For proper throttle use, refer to the indi- cations listed on the decal near the throttle handle. Green area “A” :
This area indicates the engine speed is approxi- mately 1700 RPM which is the value recommended for normal operation. Red area “B” : This area indicates the engine speed is in the range of 1900 RPM which is the maximum speed allowed for the use of the backhoe. Remark Throttle speed can be monitored using the tachometer on the side instrument bezel. 2-20 WB140-2N, WB150-2N
