Note: The hoist can be mounted a beam trolley if the capacity of the trolley system is at least twice the maximum load capacity of the hoist. 3. Position the load directly under the ratchet hoist. Always connect the ratchet hoist lifting hook to a separate lifting device attached to the load, such as straps, chains, or eye bolt. DO NOT wrap the hoist lifting chain and hook around the load in any way. If you do, the dynamic loads could exceed the capacity of the hoist, causing it to fail and drop the load. A falling load could cause death or serious crushing injuries. 4. Flip the lever on the ratchet handle to the neutral ("N") position. This allows the lifting chain to freely move through the gear block housing by either pulling on the lifting chain or rotating the handwheel. 5. Make sure the chains are not tangled, then attach the lifting hook to the load. 6. Eliminate the slack in the lifting chain between the gear block housing and the load by pulling on the chain. 7. Flip the ratchet lever to the "UP" position, then pull on the ratchet handle until there is slight tension on the lifting chain. 8. Inspect the hoist and load to make sure that the lifting chain will stay vertical and will not twist during the lifting operation, that there is not a possibility of any type of entanglement, and that there are no obstacles in the path of the lift. 9. While keeping to the side of the lifting path, continue to pull on the ratchet handle with a slow and steady pace. Note: The ratchet mechanism will suspend the load at the current position when you release the ratchet handle. 10. To lower the load, flip the ratchet lever to the "DOWN" position, then pull on the ratchet handle with a slow and steady pace. 11. When the tension between the hoist and the load is completely released, detach the hoist hook. -5 D4065/D4057 Ratchet Hoist Manual Follow regular maintenance to keep the hoist in good working condition. To avoid serious injury from hoist failure, never attempt to repair a hoist that malfunctions or becomes damaged. Hoist repair or service must be done by a qualified technician only. The hazard of an improper repair job is that it could cause the hoist to fail and unexpectedly drop the load, which could crush or kill people below, or cause major property damage. For this reason, we strongly recommend replacing the hoist if it malfunctions or becomes damaged. To avoid contaminating the friction brake during maintenance, you must know the difference between the gear cover and the brake cover (see Figure 1). The Gear Cover will be removed during routine maintenance. The Brake Cover should only be removed by a qualified technician; it encloses the friction brake and protects it from exposure to contaminants, such as liquids or lubrication, that will cause the brake to fail under load. Gear Cover Brake Cover Can be removed May be removed by operator for only by a qualified gear lubrication. technician. Cleaning To prevent the chains from jamming, clean away dirt and debris from the outside of the hoist housing and the chains. NOTICE DO NOT submerge the hoist housing in liquid of any kind or allow liquid to enter the brake cover during cleaning, or the braking mechanism may fail to work properly. Chain Lubrication When the chains are clean and dry, apply a thin coat of light machine oil to the links with an oiled shop rag to ensure smooth movement and prevent corrosion. Storage Before storing the hoist, clean and lubricate the chains. Always store the hoist in a clean, dry, and protected area to prevent corrosion or damage. A malfunctioning or damaged hoist may drop its load and crush or kill people below, or cause major property damage. To reduce this risk, observe all care and maintenance noted in the manual. If hoist malfunctions or becomes damaged, replace it, or have it serviced by a qualified service technician. Figure 1.

Items Needed Qty Wrench or Socket 13mm.................... 2 Mineral Spirits.....................As Needed Stiff-Bristled Brush .......................... 1 Shop Rags ..........................As Needed Multi-Purpose Gear Grease......As Needed To grease the hoist gears: 1. Lay the hoist housing on a flat working surface with the brake cover facing down. 2. Remove the three lock nuts that secure the gear cover, then remove the cover (see Figure 2). Figure 2. Gears exposed. Lock Nuts Splined Gear Gear Cover Disc Gears 3. Remove the two disc gears from the housing. 4. Use mineral spirits, a stiff-bristled brush, and shop rags to clean the old grease and grime from the disc and splined gears. Take care not allow the mineral spirits or lubricant to drip into the lower ratchet housing and onto the braking mechanism. 5. When the parts are dry, apply a medium coat of multi-purpose gear grease to the gear teeth. 6. Re-...
