Hand Control Levers from DisabilityWorkTools.com require two steps for installation. The levers are delivered un-bent (straight) with a bolt-on socket. There is seldom need for permanent modification to the foot pedal. The levers often need shaped for convenience of use by specific equipment operators.
First, the socket clamps onto the shank or face of the foot pedals with four bolts. You will need a 7/16″ wrench to do this. The lever then slides into the socket and is secured with a set screw if desired. The lever can be easily removed from the socket for operators using the foot pedals. Removing the lever also opens more space for accessing the seat.
Second, the straight lever needs to be shaped specifically for the operator and machine it will be used on. Hand Control Levers must be easily pushed or pulled by the operator without bumping the steering wheel or other objects. To shape the lever, have the operator sit in the seat and grasp the Lever. Mark where bends are needed, and shape the lever with a tubing bender or heat and bend with a torch. After the lever is cooled, slide it back into the socket and make sure the operator can comfortably reach the lever and move it without interference.
The hand levers should be installed so that pulling the clutch lever disengages the clutch. The levers should be heated and shaped to maximize the ease with which the worker can reach and operate the levers. Disability Work Tools will custom shape the lever for a specific equipment pedal for $125.
