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.

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.
