Main Lift Cylinder Shimming Check
Section 7. Component Procedures Main Lift Cylinder Shimming 8. Lower the carriage at full lowering speed and make sure that the carriage does not sway when it bottoms. If the carriage sways unacceptably, check the adjustment of the main lift chains to make sure they are adjusted evenly.
Main lift cylinders may require shimming after installation. Perform the following steps to determine if shimming is necessary. 1. Position the forks in the straight ahead position. 2. Position the load handler in the center of the carriage. 3. Raise the carriage to the full elevated height. If carriage sways left or right, note the direction it sways. 4. Shim the side that the carriage sways toward using the following procedure.
Shim Installation Procedure Install up to two thin shims [0.059 in. thick (P/N 1093258/001)] or one thick shim [0.119 in. thick (P/N 1093258/002)] maximum at the top of the piston using the following procedure. 1. Elevate the telescopic slightly and block the telescopic. 2. Turn the key switch OFF and disconnect the battery connector. 3. Open the emergency lowering valve and let the pistons settle. Install the shim(s) between the shoulder of the piston ram(s) and the retaining block(s) at the top of the mast. 4. Secure shim(s) with a M6 x 12 hex head cap screw (P/N 5-001-001) to the mast retaining block. 5. Reconnect the battery connector and turn the key switch ON. 6. Close the emergency lowering valve. Raise the carriage until the piston engages the retaining blocks at the top of the mast. Make sure the cylinder stops hit evenly. 7. Readjust the lift chains. Refer to “Main Lift Chains (9600)” on page 7-92 or “Main Lift Chains (9700)” on page 7-94.
