4.0 About this manual This manual is provided by Walter Meier (Manufacturing) Inc. covering the safe operation and maintenance procedures for a JET Series S90 Manual Chain Hoist. This manual contains instructions on installation, safety precautions, general operating procedures, maintenance instructions and parts breakdown. Your machine has been designed and constructed to provide years of trouble-free operation if used in accordance with the instructions as set forth in this document.
1 Chain is available in various lengths. Specify required length when ordering. Table 1 2 Gross weight includes shipping/packaging materials. 5.
6.0 Using the Chain Hoist 6.1 Prior to Operation 1. Support for the hoist may be hook, clevis pin, trolley, or beam clamp. Whatever method of suspension is chosen, the support components must be rated equal to, or greater than the capacity of the chain hoist. 2. If the chain hoist has not been used for an extended period of time, check for proper operation before putting into service. 3. The brake mechanism must be kept clean and free from dirt, water, and oil.
5. Check that the chain is not twisted at the bottom hook. All welds should face the same direction (Figure 4). Figure 6 Figure 4 6. 2. Using a hack saw, cut through upper part of link at the weld. 3. Loosen the link, reposition link vertically at edge of vise with the level of the cut above the vise jaw (Figure 7). For hoists with two or more falls of chain, make sure the bottom hook is not capsized (turned over). This may cause the chain to twist. 6.
Do not push the link inward from the curved ends. This will distort the link. Check that the link is closed and free of twist. 8.2 Load chain removal (all models) 8. If installing entire new chain, insert end of hand chain into groove at top of hand chain wheel (see Figure 11). Rotate handwheel and pull chain through. 1. Remove split pin (A) and pin stopper (B) on the chain anchor C), allowing the end of the load chain to fall free. 9. Re-weld the link at the cut. 2.
Referring back to Figure 10: 8.6 Chain installation: 3T and 5T 4. Insert one end of chain link (D) into chain anchor (C). Referring to Figure 13: 5. Insert pin stopper (B) through chain anchor (C) and chain link (D) and secure with split pin (A). 1. After installing the load chain into load chain sprocket (B), run the remaining chain through your hand to remove any twist. The last link of the chain must be in the same direction as the first. If not, cut off the last link. 2.
8.7 Chain installation: 10T Referring to Figure 14: 1. After installing load chain into load chain sprocket (B), run the remaining chain through your hand to remove any twist. The last link of the chain must be in the same direction as the first. If not, cut off the last link. 2. Insert the last link into the left pulley of the lower hook (C). 3. Pull the load chain through and up from underside of the pulley (C, D). 4.
9.0 Inspection and maintenance 4. Chain oiling is not mandatory but will increase the life of the chain. Read and follow ANSI Inspection and Maintenance Instructions. Know the meaning of Frequent Inspection, Periodic Inspection, Normal Service, Heavy Service, and Severe Service. It is the customer’s responsibility to understand and follow all ANSI and JET inspection and maintenance instructions. 5. Leave all repairs and adjustments of internal parts to qualified repair personnel. 6.
10.0 Load and wear limits 10.1 Alloy steel chain 10.2 Hooks (top and bottom) Carefully inspect entire load chain. As illustrated in Figure 15, measure five consecutive links with calipers to measure the length. Check every three feet and especially where excessive wear is indicated. Any load chain that shows noticeable deformation or heat influence must be replaced with a new one. Never extend load chain by welding a second piece to the original. See Figure 16.
